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.

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.

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.

An authentication method includes receiving, at a processor, a signal representing an image of a serialization code and multiple flecks of a label, the flecks having a random distribution. The processor detects the serialization code and applies a modification to the image to produce a modified image. A subset of flecks of the modified image is detected, and metrics associated with each fleck from the subset of flecks are identified. The identified metrics are compared with metrics associated with a unique signature, and a message is displayed, via a user interface, indicating an authenticity of the label based on the comparison.

A security device made up of a security film (130) having (i) an array of image elements (103); (ii) an array of focusing elements (106); and (iii) at least one anti-viscid agent (115), is provided. The array of focusing elements and the array of image elements are disposed relative to each other such that a synthetic image is projected by the security film when at least a portion of the array of image elements are viewed through at least a portion of the array of focusing elements. The anti-viscid agent is coupled with the array of focusing elements.

The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses selectively located barriers to the adhesive regions. A structurally weak wavelength-selective material includes portions that contact the adhesive regions and break to remain in contact with the adhesive. The wavelength-selective material does not contact the adhesive regions covered by the barrier and is removed leaving a wavelength-selective film in a pattern at the adhesive regions.

The present invention is directed at a method for manufacturing a card-shaped data carrier, in which a material from nature, for example wood, is installed in a particularly advantageous manner. The invention is further directed at a correspondingly adapted apparatus for manufacturing the card-shaped data carrier as well as at the data carrier itself. Further, a computer program product is proposed, having control commands that implement the method and/or operate the proposed apparatus.
