Laminar substrate for identifying falsification of e.g. passport, has dielectric layer, at which two image upper surfaces are arranged in form of pattern and lining, respectively, which are from electrically conductive material

摘要

The substrate has a dielectric layer (1), where an upper surface of an image (4) is arranged at the layer in a form of a corresponding pattern from an electrically conductive material. Another upper surface of the image is arranged in a lining, which is from the electrically conductive material. The electrically conductive material of the lining and the pattern are made from gold. The dielectric layer is a polymer foil, copolymer foil or a laminate of polymer or copolymer foil, where the foil material is polypropylene, polyethylene or polycarbonate. An independent claim is also included for a method for manufacturing a laminar substrate.
