Abstract:
A thermoplastic multilayer article comprises: a polycarbonate substrate comprising a polycarbonate composition comprising at least one of a polycarbonate homopolymer, a copolycarbonate, or a polycarbonate copolymer, the polycarbonate substrate having a first surface and an opposing second surface; and a first polyurethane layer laminated or coextruded on at least a portion of the first surface of the polycarbonate substrate, the first polyurethane layer comprising a first aliphatic thermoplastic polyurethane and a polyurethane UV stabilizer, wherein the first aliphatic thermoplastic polyurethane comprises first segments formed via a reaction of caprolactone and an aliphatic isocyanate, and second segments formed via a reaction of a chain extender and the aliphatic isocyanate.
