Abstract: The invention relates to a method of preparing a birefringent marking by printing a polymerisable liquid crystal material onto at least one side of a substrate and polymerising the liquid crystal material, to a birefringent marking obtained by this method, and to the use of the birefringent marking for decorative, security, authentification and identification applications.

Abstract: The invention relates to a method in which a chiral liquid-crystal layer is brought into contact with an extraction medium (extractant) by coating or printing methods in such a way that diffusion of substances out of the liquid-crystal layer into the extractant occurs.

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 colorless 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.

Abstract: Process for the production of an oriented plastic film from polyolefins and/or combinations of polyolefins and polyamide that are manufactured by the extrusion and/or coextrusion blowing process, where initial biaxial orientation is carried out during the blowing process and this is followed by another orientation operation.

Abstract: The invention relates to a method for printing a surface of a print material with a coating agent to produce a freely programmable printed image, in particular an optical effect, in which a coating agent having at least one temperature-dependent optically variable component is applied, in a first step, to a printing material, at least partially, by a printing process and, in a second step, is subjected to a temperature treatment, at least locally, to produce at least one printed image, in particular an optical effect of the printing material, in particular the printed surface of the printing material. Furthermore, the invention relates to a printed product having a coating agent applied to it, in which the coating agent has at least one temperature-dependent optically variable component, in particular liquid crystals, to produce a variable printed image, in particular at least one optical effect.
