Abstract
The invention relates to a print carrier, in particular data or information carriers, which is provided at least in some areas with a transparent anisotropic layer, in particular an optically colourless birefractive layer, in particular which is arranged on a layer-oriented structure. Furthermore, the invention relates to a method for producing a print carrier with an optically anisotropic layer arranged at least in some areas on it, in which an anisotropic layer, in particular a birefractive nematogenous layer comprising liquid crystals, is applied by means of a printing process to at least one section of the print carrier which has at least one layer-oriented structure.
