Koehl, M.M.KoehlBrucker, FranzFranzBrucker2022-03-082022-03-082003https://publica.fraunhofer.de/handle/publica/305825Die Erfindung betrifft ein Verfahren zur Beeinflussung der optischen Eigenschaften von Polymeren, bei dem in die Oberflaeche oder in oberflaechennahe Bereiche eines Polymers bzw. einer Polymerschicht Pigment-Partikel eingebettet werden.WO 200044817 A UPAB: 20001006 NOVELTY - The optical properties of a polymer (1) are modified by embedding particles of pigment (2) into a surface layer. The particles can be fully embedded in a transparent layer and can be applied by dissolving a surface layer, hot pressing, mechanical rolling, stamping, injection molding, and can be combined with imparting a surface micro-structure. USE - Changing the optical properties of a polymer, e.g. appearance, color, luminescence. ADVANTAGE - Economical method for providing durable effects even with non-compatible pigments.de608621697patent1999-19903632
