发明名称 Method for producing a laminar compound for transferring optically variable single elements to objects to be protected
摘要 The invention relates to a method for producing a lammar 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 comprises the steps of: providing a carrier substrate; applying at least one embossable layer on said carrier substrate with the contour shape of said element to be transferred; forming a diffraction structure in said embossable layer in the form of a relief; and forming a reflecting layer on said diffraction structure.
