To simplify the production of a security element 300 with a first security feature 310 and a second security feature 320, the following method is proposed: (a) Provision of a light-sensitive film 200, which comprises at least one carrier layer 210 and in surface-to-surface contact with this a light-sensitive function layer 220; (b) Exposure of the light-sensitive film 200 at least area by area, with the formation of a pattern in the light-sensitive function layer 220, wherein the security element (300) is formed with a first security feature (310); (b′) Optional fixing of the exposed light-sensitive film; and (c) Printing of the carrier layer 210 and, as appropriate, of the protective layer 230, wherein a second security feature 320 is produced.

The present disclosure is directed towards a security sheet (11) for displaying data (16). The security sheet (11) comprises a data sheet (15) for displaying data (16) and an attachment layer (17). The attachment layer (17) comprises a plurality of tabs (25) extending from an attachment portion (26) for attaching the data sheet (15) into a security document (10). The plurality of tabs (25) are attached to the data sheet (15) such that the attachment layer (17) is attached to and extends from the data sheet (15). The attachment layer (17) can comprise a textile.

An identification document including a multilayer laminate having a core layer defining an opening therethrough, and a dynamic window in the opening. The dynamic window includes an optically variable coating on at least a front or a back of the dynamic window. The optically variable coating appears transparent when viewed from the front of the identification document in light transmitted through the dynamic window from the back of the identification document toward the front of the identification document, and appears nontransparent when viewed from the front of the identification document in light reflected from the front of the identification document. Fabricating an identification document with a dynamic window includes forming an opening in a core layer, positioning a dynamic window in the opening, and plate laminating the core layer and the dynamic window between at least one outer layer on each side of the core layer.

A method is provided for producing banknotes, which include, in each case, at least one integrated circuit. The banknotes are produced from a sheet or from a material web in a production panel. In at least a plurality of these banknotes, or in each of these banknotes, an aperture is created through their substrate. In each case, an integrated circuit is arranged in the relevant aperture. In a first method step, each of the integrated circuits to be arranged in one of the apertures is arranged, with respect to the intended position in each of the banknotes that include an aperture, in the correct position on a band-shaped foil, and, in the second method step, each of these integrated circuits is transferred from this band-shaped foil onto the relevant banknote. Owing to this transfer carried out in the second method step, one integrated circuit in each case, is arranged in the aperture created in the banknotes.

A method for producing a printed material includes forming a color image having an image area ratio of 20% or less on a peripheral edge portion of a recording medium by using a coloring material; providing pressure-induced phase transition particles to a region of the recording medium, the region including the peripheral edge portion; bonding the color image and the pressure-induced phase transition particles onto the recording medium; and folding the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and pressure-bonding the folded recording medium, or pressure-bonding the recording medium having the color image and the pressure-induced phase transition particles bonded thereon and another recording medium placed on top of each other. The pressure-induced phase transition particles contain a styrene resin and a (meth)acrylic acid ester resin, the styrene resin contains styrene and a vinyl monomer other than styrene as polymerization components, the (meth)acrylic acid ester resin contains at least two (meth)acrylic acid esters as polymerization components, and a mass ratio of the (meth)acrylic acid esters is 90 mass % or more of a total of all polymerization components of the (meth)acrylic acid ester resin. The pressure-induced phase transition particles have at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures of the pressure-induced phase transition particles is 30° C. or more.

Provided is a laminated body in which a print layer is provided downstream of a laser color development layer without lowering quality. A card is provided with an offset print layer laminated on a base material, a buffer layer laminated on the offset print layer and having translucency, and a laser color development layer laminated on the buffer layer. The buffer layer minimizes scratches on the offset print layer that occur with the heat generation of the laser color development layer.
