Abstract

The refractive index of a transparent, hard-elastic amorphous plastics body is increased by means of modifying agents. A solid modifying agent dissolved in a common solvent is incorporated into the polymer or monomer solutions from which the polymer is to be formed and the solvent is removed after working and/or synthesis of the plastics material. The polymer may be thermoplastic and/or formed from a plurality of polyadditionable components. The modifying agent may be thionalide, acridine, pyrene or N- phenylurea. For impressable layer bodies, the polymerisation plastics material has a give refractive index, softening point and melting point. For those, the solvent may be tetrahydrofuran, cyclohexane, methyl ethyl ketone or dimethylformamide; for multi- components plastics materials, it is a polyhydroxy alcohol. Machine-readable information carriers comprise a carrier, the impressable modified plastics layer and a protective layer. If transparent colouring agents and/or pigments are mixed with the high-refraction lacquer, paints or colours with a particularly high sheen are obtained.
