DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) FIG. 1 shows the basic layer structure of a laminated body 1. The laminated body 1 is formed in particular in the form of a card, for example a bank card, identity card or credit card or banknote or a security document, for example an insert page of a passport booklet.

(14) The laminated body 1 has several successive films, which are laminated to form the laminated body by means of a laminating method. Of these films, several laminating films 22 to 27 and a laminating inlay 2 are shown by way of example in FIG. 1.

(15) The laminating inlay 2 has a laminating film 21 with a first surface 211 and a second surface 212 opposite it. At least one decorative ply detached from a carrier film of at least one transfer film and a radiation-curable adhesive layer, which is at least partially cured, arranged between the decorative ply and the first surface 211 of the laminating film 21 are provided in first partial regions 31 on the first surface 211 of the laminating film 211. In second partial regions 32 the at least one decorative ply is not provided on the first surface 211 of the laminating film 21 and is peeled off with the carrier film.

(16) The laminating films 21 to 27 preferably consist in each case of a thermoplastic film, and they at least partially fuse under the conditions of the laminating method used, with the result that during the laminating method the surfaces of the laminating films lying one on top of another are fused to each other at least over part of the surface, preferably over the whole surface. A corresponding intimate layer bond between the layers of the laminated body 1 is hereby achieved, which leads to a particularly high level of protection against forgery as well as resilience vis-à-vis environmental influences.

(17) At least some of the laminating films 21 to 27, preferably all of the laminating films 21 to 27, here preferably consist of polycarbonate. The laminating body 1 thus preferably has polycarbonate as main constituent. Such a laminating body is characterized by a particularly high resistance to scratching, wear and chemicals and a particularly good inter-layer adhesion, and thus has a much better fitness for use compared with usual security documents. However, it is furthermore also possible for one or more of the laminating films 21 to 27 to consist of another plastic material, for example of PET, PET-G, ABS or PVC.

(18) The laminating films 21 to 27 preferably have a layer thickness of between 30 μm and 400 μm, in particular between 40 μm and 130 μm.

(19) Thus; for example, the laminating films 21, 22, 23 and 27 in each case consist of a polycarbonate film with a layer thickness of 50 μm, the laminating films 24 and 26 consist of a multi-layered plastic film with a layer thickness of 150 μm and the laminating film 25 consists of a multi-layered laminating film, for example with a layer thickness of 350 μm, in which still further security features, for example a transponder chip and/or an antenna, which are integrated for contactless data communication.

(20) Furthermore, it is also possible for one or more of the laminating films 21 to 27 to be printed on over part of the surface or to be provided with an adhesion-promoting layer, which further improves the inter-layer adhesion to the neighboring laminating film, on the respective surfaces. A corona and/or plasma treatment can alternatively or additionally have been carried out on the respective surface to improve the inter-n layer adhesion.

(21) The laminating films 22 to 27 and the laminating inlay 2 are applied to each other for example in the sequence of layers shown in FIG. 1 and then laminated to form the laminated body 1 using heat and pressure. The laminating method to be used and the pressure and temperature to be used in the process are to be chosen here depending on the sequence of layers and the structure of the laminating films 21 to 27. A laminating method in which the sequence of layers shown in FIG. 1 is inserted between two heated rollers of a roll laminator or between the heated plates of a lifting press and, for example in the case of polycarbonate (PC), laminated to form the laminated body 1 by means of a pressure of from 10 N/cm.sup.2 to 400 N/cm.sup.2, preferably 40 N/cm.sup.2 to 200 N/cm.sup.2 and a temperature of more than 150° C., preferably between 160° C. and 210° C., is preferably used here. Other materials, such as for example PVC, can have settings deviating from this.

(22) As shown in FIG. 1, the laminating inlay 2 here is arranged in stacks of layers fed to the laminator in such a way that the first partial regions 31 with the decorative ply and the radiation-curable adhesive layer are provided between the laminating film 21 and the laminating film 22. Furthermore, preferably, as shown in FIG. 1, no further layers are provided between the two laminating films 21 and 22 in second partial regions 32, with the result that the opposing surfaces can touch the laminating films 21 and 22 in the second partial regions 32 during the laminating and thus the surfaces of the laminating films 21 and 22 are preferably fused to each other in the second partial regions 32. For the fusing of the laminating films 21 and 22, the decorative ply or decorative plies provided in the first partial regions 31 and the radiation-curable adhesive layer provided there are furthermore sunk into the laminating films 21 and 22, and thus preferably embedded in a monolithic body consisting of polycarbonate. During this process, the at least one decorative ply is protected from degradation and in particular too great a deformation by the radiation-curable adhesive layer.

(23) As already stated above, it is hereby made possible to insert decorative layers which have a low inherent stability, or in which the optical effects realized by them are particularly susceptible to the pressure and temperature loads occurring in the laminating method, into the at least one decorative ply.

(24) The area ratio of the one or more first partial regions 31 to the sum of the one or more first and second partial regions 32 here is preferably not more than 80% and in particular between 3% and 80%. It is furthermore advantageous to choose the area ratio of the first partial regions 31 to the second partial regions 32 such that the adhesion between the laminating film 21 and the laminating film 22 after the laminating is more than 3.0, preferably more than 5 Nm. And this measured in particular at a peel angle of 90°, a peeling speed of 300 mm/min and a strip width of 10 mm. The first and/or second partial regions 31 and 32 here preferably have a width of 0.1 mm or more, in particular a width of 0.2 mm or more. It is furthermore advantageous if one or more of the first partial regions 31 and/or the second partial regions 32 form raster elements of a raster which preferably comprises a plurality of raster elements, preferably more than 10, further preferably more than 20 raster elements.

(25) These measures ensure that, after the laminating, enough bonding bridges are formed between the laminating films 21 and 22 to prevent an impairment of the laminated body 1 in daily use as well as an impairment of the protection against forgery of the laminated body 1, and on the other hand to provide a decoration with good optical quality in the laminated body 1.

(26) The laminating inlay 2 can also be used in the laminating body 1 as a cover ply, wherein the transfer plies advantageously lie on the inside and are protected by the first laminating film 21. The observer thus sees the transfer plies mirror-inverted through the adhesive layer. Several transfer plies can also be applied to different laminating films and be present at different distances from the surface of the laminating body. Likewise, laminating plies can be applied to both sides of the first laminating film 21, advantageously registered relative to each other.

(27) FIG. 2 illustrates the schematic structure of the laminating inlay 2:

(28) The laminating inlay 2 has the laminating film 21, a radiation-curable adhesive layer 5 and a decorative ply 40, which is provided in one or more first partial regions 31 and is not provided in the one or more second partial regions 32.

(29) As represented in FIG. 2, the radiation-curable adhesive layer 5 is preferably arranged coextensive with and congruent with the decorative ply 40 in the first partial regions 31. However, it is also possible for the radiation-curable adhesive layer 5 to be arranged not absolutely coextensive with and congruent with the decorative ply 40, but to be formed with a slightly larger area or smaller area than the decorative ply 40. The radiation-curable adhesive layer 5 can thus, for example, not completely fill the partial regions 31 or also protrude slightly into the second partial regions 32.

(30) The decorative ply 40 provided in the first partial regions 31 is detached from the carrier film of one or more different transfer films and has at least one decorative layer. In the embodiment example according to FIG. 2 the decorative ply 40 is detached from the transfer film 4 shown in FIG. 3 and has several decorative layers 42, an adhesion-promoting layer 46 and a protective layer 45 and an optional separating layer or adhesion-promoting layer 44.

(31) The transfer film 4 has a carrier film 41 and the decorative ply 40 which is detachable from the carrier film and which has at least one decorative layer 42. In the embodiment example according to FIG. 2 and FIG. 3 the transfer film 4 furthermore also has additional optional layers, namely one or more detachment layers 43, the separating layer and/or adhesion-promoting layer 44, the protective layer 45 and the adhesion-promoting layer 46. These layers could also be dispensed with.

(32) The carrier film 41 preferably consists of a plastic film. This plastic film preferably has a particularly low surface roughness, in particular a surface roughness of less than 0.5 μm, on its surface oriented towards the carrier ply. The carrier film 41 preferably consists of a PET film and has for example a layer thickness of between 15 μm and 200 μm, for example 19 μm.

(33) The detachment layer 43 preferably has several thin layers, which reduce the detachment force between the decorative ply 40 and the carrier film 41. The detachment layer 43 here consists for example of one or more wax layers with respective thicknesses per wax layer in the range of from 0.05 g/m.sup.2 to 0.2 g/m.sup.2. The detachment layer 44 consists for example of a thin varnish layer, which is applied with an application weight of from 0.5 g/m.sup.2 to 1.5 g/m.sup.2. The detachment layer 44 can be transferred as part of the decorative ply 40 at least partially with it and/or remain on the carrier film 41 and be detached with it.

(34) The separating layer and/or adhesion-promoting layer 44 additionally supports the separation of the decorative ply 40 from the carrier film 41 and/or a later overprinting of the transferred decorative ply 40.

(35) The protective layer 45 preferably consists of a varnish layer, which is applied with a weight per unit area of from 0.7 g/m.sup.2 to 2.1 g/m.sup.2 and in particular contains one or more crosslinking components.

(36) The decorative layers 42 preferably consist of one or more of the decorative layers already described above and are in each case formed partially or also over the whole surface and thus consist for example of an at least partially formed HRI layer, a metal layer, a varnish layer, a layer containing dyes and/or pigments, in particular optically variable pigments, a volume hologram layer, an electrically conductive layer, a magnetic layer and/or a relief layer with surface relief introduced.

(37) In the embodiment example according to FIG. 3, for example, a relief layer is thus provided, into which, as indicated in FIG. 3, a surface relief is molded. This surface relief consists of different relief structures in regions, for example different diffractive gratings or different types of relief structures. For example, a first region with a matte structure, in particular an anisotropic matte structure, a second region with a diffraction grating, which generates primarily a first optically variable effect, a third region with a diffraction grating, which generates a color-change effect as zero-order diffraction structure for example when rotated, and a fourth region with a relief structure, which is formed as a blazed grating or microlens arrangement and generates an achromatic, optically variable effect. This decorative layer is furthermore, as also indicated in FIG. 3, underlaid for example with an HRI layer and/or metal layer as further decorative layer. The HRI layer and/or metal layer here can be formed over part of the surface or over the whole surface and can be formed transparent, semi-transparent or opaque, and thus correspondingly generate optical effects when observed in reflected light and/or when observed in transmitted light. Furthermore, above the relief layer, as decorative layer 42, a varnish layer containing dyes and/or pigments is provided, which in particular contains optically variable pigments in the form of interference layer pigments. This layer is preferably formed not over the whole surface, but partially and patterned, and can furthermore have opaque, translucent or transparent properties and thus generate corresponding optical effects coupled or de-coupled in the respective regions when viewed in reflected light or transmitted light.

(38) The adhesion-promoting layer 46 consists for example of a primer layer, which is applied in an application weight per unit area of from 0.02 g/m.sup.2 to 1.0 g/m.sup.2.

(39) As already stated above, the protective layer 45 and the adhesion-promoting layer 46 can also be dispensed with.

(40) The decorative ply 40 has a surface 401 facing away from the carrier film 41 and a surface 402 facing the carrier film 41.

(41) To produce the laminating inlay 2 illustrated in FIG. 2, a radiation-curable adhesive is now printed on the surface 211 of the laminating film 21 and/or the surface 401 of the decorative ply 40 of the transfer film 4. And such that the radiation-curable adhesive is applied to the respective surface 211 of the laminating film 21 and/or the surface 401 of the decorative ply in one or more first zones and forms the radiation-curable adhesive layer 5 in the one or more first zones. In contrast, the radiation-curable adhesive is not applied to the respective surface 211 of the laminating film 21 and/or 401 of the decorative ply 40 in one or more second zones.

(42) The transfer film 4 is then applied to the surface 211 of the laminating films 21. And this such that at least one partial region of the one or more first zones, in which the radiation-curable adhesive layer 5 is not applied, is arranged between the surface 401, the decorative ply 40 and the surface 211 of the laminating film 2 in at least one partial region of the one or more first zones with the radiation-curable adhesive layer 5. Then an at least partial curing of the radiation-curable adhesive layer 5 is preferably effected, whereby the adhesion between the transfer film 4 and the laminating film 21 is clearly increased in the first zones with the radiation-curable adhesive layer 5. Then the transfer film 4 is peeled off the laminating film 21, wherein in the one or more first partial regions 31 the decorative ply is detached from the carrier film 41 when peeled off and remains on the laminating film 21, and in the one or more second partial regions 32 of the laminating film of the decorative ply 40 remains on the carrier film and is peeled off with the carrier film 41.

(43) During the peeling, the decorative ply 40 “breaks” in the boundary region between the first and second zones, because of the different adhesive properties of the decorative ply 40 in the region of the first zones and second zones. This results in the effect, already described above, that the first zones and first partial regions 31 as well as second zones and second partial regions 32 substantially match, but slight deviations can result here because of the course of the breaking edge at the boundary lines.

(44) The performance of this method will now be described in detail below on the basis of FIGS. 4 to 10b:

(45) FIG. 4 illustrates by way of example production steps for producing a laminating inlay 2 as well as a production device 6 used for this:

(46) The production device 6 shown in FIG. 4 has an unwinding device 61 as well as an unwinding device 62, each of which comprises a transfer film 4 or laminating film 21 wound on a supply roll as well as a drive and/or a control device, by means of which the transfer film 4 or the laminating film 21 is unwound from the supply roll.

(47) FIG. 5 now illustrates a section from the laminating film 211 unwound by the unwinding device 62. This has two opposing surfaces 211 and 212, as indicated in FIG. 5.

(48) The laminating film 21 is preferably a film made of a thermoplastic, preferably a film containing polycarbonate (PC) as main constituent. The laminating film 21 thus consists for example of a polycarbonate film with a thickness of between 30 μm and 400 μm, preferably between 40 μm and 130 μm.

(49) The laminating film 21 preferably has at least one surface, which is designed such that it allows the UV-curable adhesive to be printed with a sufficiently good print quality and, after the curing of the UV-curable adhesive, makes a good bond possible both to the decorative ply of the transfer film 4 and, in a later laminating process, to further laminating films.

(50) By a sufficiently good print quality is meant here in particular that the lines can be printed up to 0.2 mm wide, preferably up to 0.1 mm wide, without interruptions in the line. This allows text to be produced up to a font size of 1 point, in particular up to a font size of 2 points. Furthermore, surface areas and lines must be printable in a covering manner, without holes or double edges (squeezed edges, in particular in the case of flexographic printing) or edges which smear.

(51) In order to achieve a correspondingly good print quality, it has proved to be essential to set the surface roughness of the laminating film in a correspondingly targeted manner. For this, it has proved to be advantageous to choose the surface roughness of the laminating film 21 such that it has a roughness Ra of less than 2 μm, further preferably Ra of less than 0.8 μm.

(52) It has furthermore proved to be advantageous to choose a surface with a gloss level which below 60° has according to ISO 2813 of more than 98.

(53) The laminating film 21 is now fed to a printing device 63 by means of a web-guiding device, not shown. The surface 211 here is preferably correspondingly optimized, as explained above, for achieving a good print quality.

(54) Furthermore, it is also possible to also provide one or more further machining stations before the feeding to the printing device 63. These machining stations can be for example machining stations which further improve the surface quality of the surface 211 for the subsequent machining processes. Thus, it is possible for example to provide cleaning devices here, for example cleaning brushes with compressed air support, surface-treatment devices which carry out a surface treatment by means of corona and/or plasma treatment, corresponding rolling and/or annealing devices which optimize the surface quality and in particular surface roughness, as described above, etc. Furthermore, it is also possible to provide still further printing devices, transfer devices or the like here, which apply additional register marks or decorative elements to one of the surfaces 211 and/or 212 of the laminating film 21.

(55) The printing device 63 is preferably a flexographic printing device. However, it is also possible for this to be a gravure printing or screen printing device or to be a digital printing device, for example to be an inkjet printing device.

(56) The printing of the radiation-curable adhesive on the laminating film 21 in the printing device 63 is illustrated by way of example in FIGS. 6a and 6b.

(57) FIG. 6a shows a sectional representation with the laminating film 21 as well as, schematically, a section of a printing roller of the printing device 63, by means of which the radiation-curable adhesive is printed onto the surface 211 of the laminating film 21. FIG. 6b schematically shows a top view of a section of the laminating film 21 with the radiation-curable adhesive printed on by the printing device 63.

(58) As shown in FIG. 6a and FIG. 6b, the radiation-curable adhesive is applied to the surfaces 211 of the laminating film 21 in one or more first zones 51 and is not applied to the surface 211 of the laminating film 21 in one or more second zones 52. The first zones 51 here are preferably, as shown in FIGS. 6c, 6b, formed in the form of patterns, letters, numbers, codes or symbols or other graphic and/or alphanumerical and/or coded motifs, and surrounded by one or more second zones 52.

(59) As already stated above, the area ratio of the first zones 51 to the total surface area, i.e. to the sum of the first and second zones 52, is here preferably to be chosen such that it is not more than 80%. Furthermore, the dimensions of the first and/or second zones 51 and 52, and their molding and arrangement relative to each other are preferably to be formed as described above with respect to the first and/or second partial regions 31 and 32, in order thus to achieve the advantages correspondingly described there after the laminating of the laminating inlay 2 to form the laminated body 1.

(60) Adhesives which can be cured by means of a UV radiation source or by means of e-beam (electron beam) are preferably used as radiation-curable adhesives here. These adhesives preferably contain reactive acrylates, epoxies, or enol ethers and photoinitiators. During exposure to light, the photoinitiators form radicals or reactive cations (superacids) and induce a polymerization or crosslinking reaction of longer-chain molecules. Adhesive components can be for example monoacrylates, diacrylates, triacrylates, oligomers and monomers.

(61) Adhesives which contain photoinitiators which react to different wavelengths can furthermore also be used here as radiation-curable adhesives, with the result that the curing of the adhesive can hereby be carried out in a very targeted manner in several successive curing steps.

(62) Radiation-curable adhesives in which the crosslinking reactions can be initiated by means of wavelengths between 250 nm and 420 nm, preferably in the range between 350 nm and 400 nm, are preferably used.

(63) For example, an adhesive with the following formula n be used as radiation-curable adhesive: Urethane acrylate oligomer 40% Acrylate monofunctional 2(2-ethoxyethoxy)ethyl acrylate/(EOEOEA) 10% Acrylate difunctional ethoxylated (5) hedanediol diacrylate/(HD(5EO)DA) 15% Aliphatic urethane acrylate oligomer 20% Propoxylated trimethylolpropane triacrylate 10% Initiator 5%

(64) In the case of the application by means of flexographic printing, the UV-curable adhesive is preferably printed with a dynamic viscosity of between 400 mPas and 2,000 mPas, preferably 500 mPas to 1,200 mPas.

(65) It has been shown that a correspondingly good print quality can be achieved hereby.

(66) Furthermore, it is also possible for the printing device 63 to have a curing device, by means of which the UV-curable adhesive is pre-cured during the printing or immediately after the printing. For this, it has proved worthwhile to carry out a pre-curing of the adhesive of more than 50%, preferably more than 80, and/or to increase the dynamic viscosity of the radiation-curable adhesive by means of the pre-curing by a value of from 20 mPas to 3,000 mPas, preferably by 50 mPas to 1,000 mPas. It has been shown that, through these measures, the print quality can furthermore be clearly improved, or respectively the stability of the radiation-curing adhesive is improved during the feeding of the transfer film.

(67) In addition to the use of flexographic printing, the radiation-curable adhesive can also be printed by means of gravure printing, screen printing or digital printing or a combination of these printing methods.

(68) In the case of gravure printing, the desired design is copied onto a gravure roller. With such a gravure roller, corresponding to the known gravure printing method, the radiation-curable adhesive is then printed onto the laminating film 21. The viscosity of the radiation-curable adhesive is preferably chosen to be less than 1,000 mPas in the case of gravure printing. Here too, the combination with a pre-curing device, as already stated above, has proved worthwhile in order to prevent a smearing of the radiation-curable adhesive in the subsequent process as far as possible.

(69) Furthermore, it is also advantageous to print the radiation-curable adhesive by means of an inkjet printhead. In comparison with printing methods using fixed printing blocks, even individual, real-time designs are hereby possible. Here too, the use of a pre-curing device has proved worthwhile.

(70) Furthermore, it is also possible for the printing device 63 to comprise different printing tools, for example a combination of a screen printing tool and/or a flexographic printing tool and/or an inkjet printing mechanism.

(71) The transfer film 4 is unwound by the unwinding device 61 and initially fed to an optional surface-machining device 65 via web-guiding devices, not shown.

(72) The transfer film 4 is for example constructed as illustrated in FIGS. 7a and 7b: the transfer film 4 has a carrier film 41, an optional detachment layer 44 and a decorative ply 40, which consists of one or more decorative layers 42.

(73) The decorative ply 40 has a surface 401 facing away from the carrier film 41 and a surface 402 facing the carrier film 41.

(74) The decorative layers 42 here can be formed as already described above in FIG. 2 and FIG. 3 with respect to the decorative layers 42. Here, the decorative ply 40 preferably has regions 421, 422 and 433, in which one or more of the decorative plies 42 are formed differently. Thus, by way of example, a top view of a section of the transfer film 4 with the three regions 421, 422 and 433 is shown in FIG. 7b, in which one or more of the decorative plies 42 are formed differently. Thus, it is possible for example for different optical relief structures, which generate in each case a different optically variable appearance, for example a different color change, when tilted and/or rotated, to be introduced into one of the decorative layers 42 in the regions 421, 422 and 433.

(75) The optional surface-machining device 65 consists for example of a device which improves the surface quality of the surface 401, of the decorative ply 40 by means of corona and/or plasma treatment. Furthermore, it is also possible to provide the machining station already described above with respect to a pre-treatment of the laminating film 21 in addition to or as an alternative to the surface-machining device 65.

(76) Optionally, the printing of the adhesive layer 5 can also be effected onto the transfer film 4 or a printing can be carried out both on the laminating film and on the transfer film 4. The two adhesive layers can be different or also similar or identical in terms of the composition and/or application weight.

(77) The laminating film 21 and the transfer film 4 are then fed to a laminating device 64 via web-guiding devices, not shown. The laminating device 64 consists for example of two rollers, which bring the radiation-curable adhesive layer 5 printed on the surface 211 of the laminating film 211 into contact with the surface 401 of the decorative ply 40 of the transfer film 4 via roller gap formed between them.

(78) This is illustrated by way of example in FIGS. 8a and 8b:

(79) FIG. 8a schematically shows a section of the two rollers of the laminating devices 64, which correspondingly bring together the laminating film 21 and the transfer film 4, with the result that the radiation-curable adhesive layer 5 is arranged between the laminating film 21 and the decorative ply 40. It is advantageous here to choose the contact pressure correspondingly, that the radiation-curable adhesive layer 5 wets both the surface 211 of the laminating film 21 and the surface 401 of the decorative ply 40 in the region of the first zones 51. The contact pressure of the laminating device 64 here is preferably to be set in such a way that a smearing of the radiation-curable adhesive layer is avoided during the laminating. For this, it has proved worthwhile to choose the contact pressure of the laminating device 64 to be between 0.05N/cm.sup.2 and 100 N/cm.sup.2, further preferably between 1 N/cm.sup.2 and 10 N/cm.sup.2.

(80) Furthermore, the application of the transfer film 4 to the laminating film 21 is preferably controlled by means of a registration device. This registration device preferably has regulating means, by means of which it can bring about an alteration of the distance or tension of the laminating film 21 and/or the transfer film 4. By means of these regulating means and data about the positioning of the adhesive overprint, the laminating film 21 and/or the transfer film 4, which it detects for example by means of optical sensors, it regulates the positioning of the laminating film 21 with the radiation-curable adhesive layer 5, as well as the transfer film 4 with the differently formed decoration regions relative to each other in such a way that the adhesive overprint and the allocated regions of the transfer film 4 are applied to each other registered relative to each other by the laminating device 64.

(81) A further option for registered transfer is to vary the circumferential speed of the printing tool, for example the printing roller or the printing screen relative to the movement speed of the transfer film 4 or the laminating film 21. This varying, known as tracking, can be −10 per mil to +10 per mil, preferably −5 per mil to +5 per mil of the movement speed of the transfer film 4 or the laminating film 21. This tracking can particularly preferably be carried out by means of inkjet, by controlling the ink ejection correspondingly in terms of timing, i.e. delaying or accelerating it. A combination of extending/adapting the distance of the transfer film 4 or the laminating film 21 and a tracking of the printing mechanism can also be used.

(82) If the transfer film 4 is fed not as a single coherent web, but as several webs in individual webs separated from each other, the relative positions of the several webs are detected and synchronized through suitable measures described above.

(83) This is illustrated for example in FIG. 8b, which illustrates a top view of the transfer film 4 laminated onto the laminating film 21 by the laminating device 64 after the laminating: as shown there, the regions 421, 422 and 423 of the decorative ply 40, in which it has different decorative layers, overlap here with correspondingly allocated first zones 51, in which the radiation-curable adhesive layer is provided. Thus, for example, the punctiform first zone 51 overlaps the allocated region 423, the cruciform first zone 51 overlaps with the allocated region 422 and the first zone 51 formed in the form of a lettering overlaps with the allocated region 421.

(84) In order to guarantee this registration, register marks are preferably applied during the overprinting of the radiation-curable adhesive by means of the printing device 63, for example in the form of an overprint, a perforation, etc. Corresponding register marks are preferably also applied to the transfer film 4 or are already provided in the transfer film 4. Alternatively, the registration can also be effected through corresponding image acquisitions of decorative elements of the transfer film 4 or the laminating film 21 or the radiation-curable adhesive layer 5.

(85) The layer structure of transfer film 4 and laminating film 21 is then fed to a curing device 65.

(86) The curing device 65 is preferably a UV emitter or e-beam emitter. It has proved worthwhile here for example to use a mercury vapor lamp in such a way that a UV dose of more than 50 mJ/cm.sup.2 is achieved. This can be in particular a radiation doped with iron or gallium. Furthermore, a UV-LED emitter can also be used. It is furthermore also possible here not to carry out the irradiation over the entire width of the material web, but to carry it out only selectively in the regions in which the radiation-curable adhesive layer 5 is provided. This can be effected for example through the use of corresponding masks or through corresponding activation, for example of a UV emitter matrix.

(87) A corresponding irradiation of this layer structure with the curing device 65 is shown in FIG. 9: thus, for example, the layer structure consisting of carrier film 41, optional detachment layer 44, decorative ply 40, radiation-curable adhesive layer 5 and laminating film 21 is irradiated from sides of the carrier film 41 with the radiation source of the curing device 65. Furthermore, it is also possible to carry out the irradiation from the opposite side, or to provide several radiation sources, also on both sides of the layer structure according to FIG. 9, in the curing device 65.

(88) Furthermore, it is also possible to dispense with the curing device 65 if the radiation-curable adhesive layer 5 already ensures a sufficient difference in adhesion in the first and second zones 51 and 52 in the present state.

(89) The present layer structure is then fed to a separating device 65. The separating device 65 preferably consists of a pair of rollers and/or a deflection about a knife blade and/or a separating blade and/or a blast air strip, or a combination thereof, which allows the transfer film 4 to be peeled off the laminating film 21 under controlled conditions.

(90) During the peeling, the difference in the inter-layer adhesion between the first zones 51 with the radiation-curable adhesive layer 5 and the second zones 52 without the radiation-curable adhesive layer 5 between the decorative ply 40 and the laminating film 21 has the effect that in first partial regions 31 the decorative ply 40 is detached from the carrier film 41 when peeled off and remains on the laminating film 21, and in second partial regions 32 the decorative ply 40 and the carrier film 41 remains and is peeled off with the carrier film 41.

(91) This is illustrated by way of example in FIG. 10a and FIG. 10b:

(92) FIG. 10a shows a sectional representation of the layer structure after peeling off. A layer structure of the radiation-curable adhesive layer 5 and the decorative ply 40 is provided on the laminating film 21 in the first partial regions 31 on the surface 211. This layer structure forms a laminating inlay 2, which is wound onto a supply roll in a winding device 67. The “rest” of the transfer film 4 peeled off this only has the decorative ply 40 still in the second partial regions 32. This rest of the transfer film is fed to a winding device 66 and wound onto a supply roll there. This rest can optionally be re-used in order to make it possible to utilize the decorative ply 40 as much as possible.

(93) FIG. 10b shows a top view of a section of the laminating inlay 2: because of the above-described register-accurate application of the transfer film 4 relative to the radiation-curable adhesive layer 5, the laminating inlay 2 has different first partial regions 31, in which different motifs with different optically variable effects are produced.

(94) The procedure according to FIG. 4 is a roll-to-roll machining process, which preferably proceeds at a rate of between 0 al/min and 80 m/min, preferably between 15 m/min and 45 m/min. Alternatively, however, the method can also be carried out in a sheet method, in which individual sheets are correspondingly printed, laminated, cured and separated.

(95) The laminating inlay 2 produced according to FIG. 4 can then also be processed further by means of a sheet-based method. For this, the width of the laminating films 21 corresponds at least to the width of the sheet format used for this or a multiple of this sheet format. The laminating film 21 can furthermore also have a larger width for the transfer process and the edges can be cut to the desired width in a later machining process. An excess width has the advantage that, because of the subsequent cutting, the edges are clean, and possible tolerances of the printing relative to the web edge can be compensated for. However, logistical reasons can also argue for this if a web width is easily available or can be used as standard. Furthermore, depending on the plant design for precisely advancing the laminating film 21, transport tracks can necessarily be provided there, which have to be removed. It can also be necessary to apply position marks or register marks and other items of information, control tracks, etc. to the laminating film 21, which then have to be cut off again subsequently.

(96) Furthermore, an adhesive layer can additionally also be printed on the laminating film 21 in order to improve the adhesion for the laminating with plastic films, for example made of PET, PET-G, ABS and PVC, This coating can be effected on one or both sides and can be effected for example before the radiation-curable adhesive is printed on and/or after the transfer film is peeled off.

(97) During the laminating of the laminating inlay 2 with further laminating films to form a laminated body, a roll-to-roll process, but also a sheet-based process, can likewise be used. It is advantageous here likewise to provide a corresponding registration between the films laminated with each other.

(98) The laminating inlay 2 here can have the same width in the format as the laminating films with which it is laminated. Furthermore, it is also possible for the laminating inlay 2 to be fed on the basis of several individual rolls, which have for example the width of the individual documents. Advantageously, the width of the film rolls with the laminating inlay 2 here is a little larger than the counter-laminated laminating film in order to mask lateral tolerance during the feeding or in order to leave space for register marks and further technical tracks necessary if need be.

(99) In the case of individual tracks fed, it is particularly advantageous that these individual rolls are guided registered relative to each other, both transverse to and along the direction of travel.

(100) The laminating inlay 2 can also be correspondingly cut to size and finished before the laminating with further laminating films, in order to be processed further for example in a sheet process. Thus, the laminating inlay 2 can for example be cut to sheet format or cut into webs with a smaller width, in order to adapt the film width to that of a belt laminator which is used for the lamination with the further laminating films. For the laminating, the laminating inlay 2 is bundled with one or more laminating films to form a laminating packet, which preferably corresponds to the desired security document. After the laminating, the desired document formats are stamped out of the joined plates and processed further e.g. with personalization.

(101) Further materials that can be laminated consist for example of a carrier made of polyester, which is coated with a heat seal adhesive. Typical thicknesses lie in the range between 25 μm and 200 μm, both with respect to the polyester carrier and with respect to the heat seal adhesive. The decorative plies are applied to the surface of the adhesive layer. After application, at least partial overcoating with a further adhesive layer is effected, with the result that a bond to the document substrate is also achieved in the region of the decorative ply in the subsequent laminating process. Such a structure is suitable in particular to prevent manipulation attempts. Such laminating films are used for example to seal paper-based documents on one or two sides in a roll laminator.

(102) Furthermore, it is also possible for the process illustrated in FIG. 4 to be repeated multiple times with different transfer films 4 or for not only one, but several transfer films 4 to be brought into contact with the laminating film 21 at the same time or in succession in the process shown in FIG. 4. Furthermore, it is also possible here to use in each case different radiation-curable adhesives or to use differently dyed radiation-curable adhesives. The furthermore applied decorative plies 40 can here be applied to the same side of the laminating film 21, or also to different sides of the laminating film. The decorative plies 40 applied by means of different transfer films and/or radiation-curable adhesive layers here are advantageously arranged registered relative to each other. This is achieved through corresponding registration of the printing processes and/or registration of the transfer films relative thereto, as already described above.

(103) Furthermore, it is also possible for additional decorative layers to be printed, by means of further printing mechanisms, on the laminating film 21 and/or the decorative ply 40, preferably registered, and/or to be transferred by means of stamping processes, such as for example hot stamping.

(104) Several laminated bodies 1 in the form of security documents, which are produced by means of corresponding laminating inlays 2, are shown in FIGS. 11 to 13:

(105) FIG. 11 to FIG. 13 in each case show a laminated body 1, the layer structure of which corresponds to the laminated body according to FIG. 1.

(106) In the case of the laminated body 1 according to FIG. 11, the first partial regions 31 are formed in the form of a raster with raster elements, which are molded in the form of a sequence of letters (sequence of letters “UTO”). The decorative ply 40 provided there consists of a diffractive structure which is provided with an HRI layer and which has a background over the whole surface for the further security elements provided in the layer structure, here a passport photo 35 as well as individual items of information 33 and 34 produced by means of laser personalization. The first partial regions 31 here are surrounded over the whole surface by a second partial region 32.

(107) The laminated body 1 according to FIG. 12 has first partial regions 311, 312, 313 and 314, which in each case have decorative plies 40 of different transfer films 4. In the first partial regions 311 a decorative ply 40 is provided, which is formed of a diffractive structure and an HRI layer. The first partial region 312 is provided with a decorative ply 40, which has only an HRI layer. The first partial regions 313 have a decorative ply 40 with an HRI layer, wherein the radiation-curable adhesive layer is applied here by means of a digital printing method, in particular inkjet printing.

(108) Furthermore, it is also possible for the first partial regions 313 to have an overprint produced by means of a digital printing method, in particular inkjet printing, in particular a personalized overprint. This overprint is for example printed onto the decorative ply 40 or onto the laminating film 21. The radiation-curable adhesive layer 5 preferably overlaps this overprint at least in regions.

(109) The first partial regions 314 have in each case a structured metal layer registered relative to a further diffractive structure. The first partial regions 311, 312, 313 and 314 here are arranged registered relative to each other and furthermore registered relative to the remaining security features 35, 34, and 33. This is achieved through the above-described measures.

(110) The partial regions 311 and 314 here in each case form a motif region, inside which in each case at least one motif of the decorative ply 40 is provided. The molding of the respective motif region is indicated with respect to the partial regions 311 by means of a dashed outline, inside which a motif in the form of a spiral is arranged by way of example. With respect to the partial regions 314, in FIG. 12 this is indicated by a border line, by way of example a rectangular, circular and octagonal border line, which forms the boundary line of the respective motif region and in which in each case at least one motif is provided in the decorative ply 40, here in the form of the letters U, T and O by way of example.

(111) The motif regions here preferably have a closed contour line, which is formed in particular in the form of a geometric figure, a logo, an alphanumeric character or a pattern. Inside the respective motif region, one or more motifs are provided, which are preferably formed in the form of alphanumeric characters, codes, graphics, images or patterns. Outside the motifs, the respective partial region 311 or 314 of the decorative ply is preferably formed transparent and for example has no opaque decorative layer in these partial regions. Here, the transparency outside the motifs of the decorative ply 40 is preferably formed such that for the human observer the decorative ply 40 is indistinguishable from the background there and thus does not appear optically for the human observer.

(112) In the first partial regions 311, the laminated body 1 according to FIG. 13 has a decorative ply 40 with an HRI layer and a diffractive structure, which is provided on a dyed, radiation-curable adhesive layer 5. The color of the diffractive structure is thus determined correspondingly by the radiation-curable adhesive layer 5. The first partial regions 312 have a decorative ply 40, which have a patterned varnish layer with IR pigments as well as optionally further decorative layers. Here too, the first partial regions 311 and 312 are arranged registered relative to each other as well as to the further security features 31, 34 and 35. This is achieved through the above-described measures.

(113) FIG. 14 shows a laminated body 1 with the laminating inlay 2 and the laminating film 21, which is in particular the above-mentioned first laminating film, as well as the laminating film 22, which is in particular the above-mentioned second laminating film, and the laminating film 71, which is in particular the above-mentioned first laminating film of the one or more further laminating films. Here, the laminating film 21 advantageously comprises polycarbonate, wherein the laminating film 71 and the laminating film 22 preferably comprise polyvinyl chloride.

(114) FIG. 14 shows in particular the layer structure shown in FIG. 1 of a laminated body 1, except for the fact that the laminating films 23 to 27 are not shown, and the laminating film 71 is shown instead. However, it is also conceivable that at least one of the laminating films 23 to 27 is provided and/or laminated to form the laminated body.

(115) The laminating film 21 is preferably opaque, in particular in the wavelength range visible to the human eye. The laminating films 22 and 71 here are preferably transparent, in particular in the wavelength range visible to the human eye. It is furthermore also possible for the laminating film 21 to be white and/or to be printed for the human eye.

(116) With respect to the design of the laminating inlay 2, in particular the decorative ply in the first partial regions 31 of the laminating inlay 2, reference is made here in particular to FIG. 1 and/or FIG. 2.

(117) FIG. 15 shows the laminated body 1 shown in FIG. 14, except for the fact that a lasered partial region 100 is introduced into the laminating inlay 2, in particular the laminating film 21, which preferably forms a grayscale image, in particular through a halftone raster generated by means of lasers. The lasered partial region 100 here is arranged, for example when viewed perpendicular to a plane spanned by the laminating film 21, preferably in the direction from the laminating film 22 to the laminating film 21, registration-accurately under and next to the first partial regions 31.

(118) FIG. 16 shows a laminated body 1 with the laminating inlay 2 and a laminating inlay 3, which is in particular the above-mentioned further laminating inlay, with the laminating films 21, 22 and 71 and with the laminating film 73, which is in particular the above-mentioned third laminating film of the one or more further laminating films.

(119) FIG. 16 shows in particular the layer structure shown in FIG. 1 of a laminated body 1, except for the fact that the laminating films 23 to 27 are not shown, and the laminating films 71 to 73 are shown instead. However, it is also conceivable that at least one of the laminating films 23 to 27 is provided and/or laminated to form the laminated body 1.

(120) The laminating inlay 3 has first partial regions 311, which are in particular the above-mentioned one or more further first partial regions with the further decorative ply, and has second partial regions 321, which are in particular the above-mentioned one or more further second partial regions.

(121) With respect to the design of the laminating inlay 3, in particular the decorative ply, preferably the further decorative ply, in the first partial regions 311 of the laminating inlay 3, reference is made here in particular to FIG. 1 and/or FIG. 2.

(122) As can be seen in FIG. 16, the first partial regions 311 and the second partial regions 321 of the further laminating inlay 3 can be designed offset relative to the first partial regions 31 and the second partial regions 32 of the laminating inlay 2 represented at the top in FIG. 16.

(123) Furthermore, it is possible for the decorative ply in the first partial regions 311 of the laminating inlay 3 and the decorative ply in the first partial regions 31 of the laminating inlay 2 represented above it to be designed differently.

(124) The laminating film 21 and the laminating film 72 preferably consist of polycarbonate and/or comprise polycarbonate, wherein the laminating films 22, 71 and 73 preferably consist of polyvinyl chloride and/or comprise polyvinyl chloride.

(125) The laminating film 71 is preferably opaque, in particular in the wavelength range visible to the human eye. The laminating films 71, 21, 73 and/or 22 are preferably transparent, in particular in the wavelength range visible to the human eye.

(126) Advantageously, the laminating film 71 is single- or multi-layered and in particular acts as adhesion-promoter between the laminating film 21 and the laminating film 72.

(127) The laminating film 21, 71 and/or 72 is preferably machined by means of a laser at least partially through one of the partial regions 31 and/or 311 of the laminating inlay 2 and/or of the laminating inlay 3, in particular with the result that a lasered partial region is arranged registration-accurately over, under and/or next to the first partial regions 31 and/or 311 of the laminating inlay 2 and/or of the laminating inlay 3.

(128) Furthermore, it is preferably possible for additional laminating inlays made of additional laminating films with additional decorative plies to be arranged in the laminated body 1, in particular on a side of the laminating film 22 and/or of the laminating film 73 facing away from the laminating film 21.

(129) In FIG. 16 additional laminating films are also conceivable, in particular which are arranged on the side of the laminating film 22 and/or of the laminating film 73 facing away from the laminating inlay 2 and/or the laminating inlay 3 and/or on an additional laminating inlay and which in particular comprise polyvinyl chloride and/or are made of polyvinyl chloride and/or are transparent, in particular in the wavelength range visible to the human eye.

(130) FIG. 17 shows the laminated body 1 shown in FIG. 14 and/or FIG. 15, except for the fact that the laminated body 1 furthermore has the laminating film 73, which is in particular the above-mentioned third laminating film of the one or more further laminating films, and the laminating film 74, which is in particular the above-mentioned fourth laminating film of the one or more further laminating films.

(131) FIG. 17 shows in particular the layer structure shown in FIG. 1 of a laminated body 1, except for the fact that the laminating films 23 to 27 are not shown, and the laminating films 71 and 73 are shown instead, and furthermore in particular the laminating film 74 is shown in the layer structure.

(132) It is preferably possible here for the one or more further laminating films not to have the second laminating film of the one or more further laminating films here, in particular with the result that the laminated body 1 has a laminating inlay 2.

(133) Here, the laminating films 73 and 74 preferably consist of polyvinyl chloride and/or comprise polyvinyl chloride. The laminating films 73 and 74 are preferably transparent, in particular in the wavelength range visible to the human eye.

(134) Furthermore, it is preferably possible for additional laminating inlays made of additional laminating films with additional decorative plies to be arranged in the laminated body 1, in particular on a side of the laminating film 74 and/or of the laminating film 73 facing away from the laminating film 21.

(135) Additional laminating films are also conceivable, in particular which, in FIG. 17, are arranged on the side of the laminating film 73 and/or of the laminating film 74 facing away from the laminating inlay 2 and/or the laminating inlay 3 and/or on an additional laminating inlay and which in particular comprise polyvinyl chloride and/or are made of polyvinyl chloride and/or are transparent, in particular in the wavelength range visible to the human eye.
