Abstract
Invention concerning a method for the production of a multilayer matte coated surface, where the carrier (1) is covered with a layer of coating (4) containing an additive to increase the bond strength of the coating between the layers.

A least one other layer of coating with bond strength improving additive is applied to the first layer, which is again exposed to excimer radiation and an electron beam or UV radiation with the same dose as for the first layer. if the second layer is the outer layer, i.e. the last layer (6), the entire surface is treated with an electron beam with the dose required to finish the polymerisation process of all coating layers, or is treated with appropriate UV radiation, in order to achieve an adequate hardening effect.

EXAMPLE 1A—POSITIVE MOULD, SYNCHRONOUS EFFECT
[0026] The foil production process is based on rotary intaglio printing. A wood-like design pattern 2 is applied onto carrier 1 which is made of paper foil. The design is transferred onto the band by pressing it with a special roller coated with rubber of adequate hardness to the printing cylinder. The cylinder is immersed in a rotating toner container with a feed roller. Excess paint is removed by means of an adjustable scraper blade on the printing cylinder. The band with the paint is then dried in a hot air chamber and afterwards transported to the next printing unit. The carrier passes through three printing stations. This process is performed with the use of water-soluble paints.
[0027] The next stage is to coat the carrier 1 with a protective layer 3. This is achieved by means of a special intaglio cylinder for the application of the primer 3717.212. The cylinder applies about 6 g/m.sup.2 of the primer which, like the paint, is hardened in a gas dryer at a temperature of 140° C.
[0028] The next step is to apply the first layer of EB coating 4 by means of a 3WS coating system. At this stage of the process, the coat A has the following composition: [0029] FL 27692—1 part [0030] FLE 27800—0.1 parts [0031] FZ 2711—0.07 parts [0032] FZ 2720—0.15 parts

[0036] The obtained surface has a gloss level below 6° measured in a 60° geometry. Then the carrier band is transported to a station with an intaglio cylinder with a synchronous pattern for the different elements of the main design. The structure 6 is imprinted using coating B composed of: [0037] FLE 27800—1 part [0038] FZ2720—0.15 parts
[0039] The surface is exposed to an excimer lamp and then hardened by means of electrons in an EB generator over the entire thickness of all coating layers. The hardening parameter values are: [0040] Dose 40 kGy [0041] High voltage 110 kV
[0042] The obtained foil, a cross-section of which is presented in
[0043] The content of the coating mixture in both application units is characterised by a special additive improving the bond strength between the individual layers. An additional condition for achieving good bond strength is that the coatings are subjected to a preliminary polymerisation (gelatinisation) of the coating layer at the stage of the production of the first matte surface coating.

The structure is imprinted using coating B 6 composed of: [0240] FLE 27800—1.0 parts [0241] FZ2720—0.15 parts
[0242] The surface is exposed to an excimer lamp and then hardened by means of electrons in an EB generator over the entire thickness of all coating layers. The hardening parameter values are: [0243] Dose 40 kGy [0244] High voltage 110 kV
[0245] The obtained foil offers, apart from the visual effect of the imprinted design, also a three-dimensional impression. The “porous” structure not correlating with the different elements of the main design has a gloss level of 1-2° measured in a 60° geometry.
[0246] The content of the coating mixture in both application units is characterised by a special additive improving the bond strength between the individual layers. An additional condition for achieving good bond strength is that the coatings are subjected to a preliminary polymerisation (gelatinisation) of the coating layer at the stage of the production of the first matte surface coating.
