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.
