  • Publication number: 20220152971
    Abstract: The present invention relates to a layer arrangement, having: a foil layer (100) provided with optical information, and a three-dimensionally structured layer (200) having a smooth side (210) and a structured side (220) opposite the smooth side (210), wherein the structured side (220) has at least one face (230) which is not coplanar with the smooth side (210) and faces a previously defined reference location (400), and the structured side (220) has at least one face (235) which is not coplanar with the smooth side (210) and faces away from the previously defined reference location (400). The three-dimensionally structured layer (200) is formed by a thermoplastic polymer which has an optical haze Ty (D65/10°) according to ASTM D1003 of ?10% with a layer thickness of 4 mm. The foil layer (100) provided with optical information is connected to the structured side (220) of the three-dimensionally structured layer (200).

  • Patent number: 10526504
    Abstract: The present invention relates to a coating composition comprising at least one thermoplastic acrylonitrile-butadiene-styrene copolymer in a content of at least 30% by weight of the solids content of the coating composition, at least one UV-curable reactive diluent in a content of at least 30% by weight of the solids content of the coating composition, at least one photoinitiator in a content of ?0.1 to ?10 parts by weight of the solids content of the coating composition and at least one organic solvent, where the proportion of ethylenically unsaturated groups is at least 3 mol per kg of the solids content of the coating composition. This is used to provide films and mouldings coated therewith, having a metallizable, scratch-resistant and solvent-resistant surface.
