Abstract

Record carriers on the basis of layers of plastic having features in the form of patterns or characters, the light-dark contrast of which changes from incident light to transmitted light, which are available in the form of information which is applied with the aid of a laser beam and modifies the optical characteristics of the record carrier material, the visual impression of which is different when viewed in incident light from that when viewed in transmitted light, and a method of producing said record carriers by generating information having a different visual impression by destroying a pigment which is dispersed in the substrate and absorbs and/or reflects the light with formation of light-permeable reaction products with the aid of a laser beam in the substrate.
