A hot-stamping foil has a carrier that is a base film or a coated base film, and a laminated optical decoration formed on the carrier in a removable manner. The laminated optical decoration includes a laminated optical structure, an anchor layer formed on the laminated optical structure at a side opposite against the carrier, the anchor layer being a mixture of an acid-modified polyolefin and a vinyl chloride-vinyl acetate copolymer, and an adhesive layer which is formed on the anchor layer at a side opposite against the laminated optical structure. The adhesive layer has an adhesive domain containing an acid-modified polyolefin as a major component, and a non-adhesive domain containing a blocking preventing agent as a major component. The blocking preventing agent is one or both of a resin filler and an inorganic filler. A glass transition point of the blocking preventing agent is greater than 60° C.

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.

The present invention relates to a metal card manufacturing method including the steps of: preparing a metal sheet having a given size capable of accommodating a plurality of individual cards; forming holes on at least one or more edges of stacked sheets formed by stacking a plurality of sheets inclusive of adhesive sheets and an inlay sheet on which antenna coils are printed, the plurality of sheets having the same size capable of accommodating the plurality of individual cards as each other; fitting the holes formed on the stacked sheets to pins located on a loading plate; placing the metal sheet on top of the stacked sheets; forming a metal card sheet through lamination among the metal sheet and the stacked sheets; and cutting the metal card sheet along individual card outlines of the plurality of individual cards.

An identification document includes a first layer and a second layer fused to the first layer. The first layer and the second layer include polyester, and the identification document is non-delaminable. Forming the identification document includes providing variable data on a surface of a first layer including polyester, aligning the first layer and a second layer including polyester, and fusing the first layer and the second layer to yield a fused identification document.

An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. The images can produce one or more optical effects.

A display body includes a base material having a first region, a second region, and a third region. In the display body, the first region is formed with a code or an image of identification information, and the second region is formed with a hidden code containing information obtained by encoding at least a part of the identification information. An encrypted ciphertext is recorded in the third region, and the ciphertext is generated from at least one of the code of the identification information and the hidden code.

An optical product includes an array of lenses and first and second plurality of portions disposed under the array of lenses. Individual ones of the first plurality of portions can correspond to a point on a surface of a first 3D object, and include first non-holographic features configured to produce at least part of a first 3D image of the first 3D object. Individual ones of the second plurality of portions can correspond to a point on a surface of a second 3D object, and include second non-holographic features configured to produce at least part of a second 3D image of the second 3D object. The optical product can include an interference optical structure disposed with respect to the first and/or second non-holographic features.

A topcoat layer that has a defined surface structure on an outer surface thereof once the topcoat layer is laminated to a substrate. The surface structure of the topcoat layer provides a matte surface finish to the underlying substrate. Any attempt to alter the substrate or the topcoat layer will result in disruption or destruction of the surface structure of the topcoat layer making such tampering evident. Replication of the surface structure of the topcoat layer by a counterfeiter is also difficult without the appropriate equipment.
