Patent ID: 7241494

Claim:
A radiation-curable, composite layered sheet or film comprising at least one substrate layer, one outer layer, and a coloring interlayer between the at least one substrate layer and the outer layer, wherein the at least one substrate layer comprises a thermoplastic polymer selected from the group consisting of polymethyl methacrylates, polybutyl methacrylates, polyethylene terephthalates, polybutylene terephthalates, polyvinylidene fluorides, polyvinyl chlorides, polyolefins, polyamides, polycarbonates, acrylonitrile-butadiene-styrene (ABS) polymers, acrylic-styrene-acrylonitrile (ASA) copolymers, acrylonitrile-ethylene-propylene-diene-styrene copolymers (A-EPDM), polyether imides, polyether ketones, polyphenylene sulfides, polyphenylene ethers and mixtures thereof; wherein the outer layer comprises a radiation-curable composition comprising an ethylenically unsaturated binder having a glass transition temperature of more than 40° C., and wherein the ethylenically unsaturated binder is a polymer comprising more than 60% by weight of polymerized acrylic monomers.
