Abstract:
A method for producing a laminar compound for transferring optically variable elements to objects to be protected, the laminar compound comprising a carrier substrate and isolated single elements on said carrier substrate in the contour shape of the elements to be transferred, the method comprising the steps of:providing a carrier substrate;producing at least one embossable layer on that carrier substrate in the contour shape of said element to be transferred;forming a diffraction structure in said embossable layer in the form of embossed reliefs after said embossable layer is produced on that carrier substrate; andforming a reflecting layer on each of the embossed reliefs thereby forming the isolated single elements, whereby the reflecting layer is formed on the embossed reliefs so that each of the isolated single elements has an embossed, reflecting inner area and an edge area, surrounding the embossed, reflecting inner area where the embossed relief and the reflecting layer are not present.
