Patent ID: 6958190

Claim:
An article comprising a panel structure mountable in an automobile vehicle to form a part of a vehicle interior thereof, the panel structure having an exterior surface, at least a portion of which is exposed to the vehicle interior, and an interior surface, said panel structure comprising: a reinforcing substrate; a layered composite structure comprising an outer layer defining at least a portion of said exterior surface of the panel structure and an inner layer, said layered composite structure being united to a surface of said reinforcing substrate; said outer layer comprising at least one light-stable aliphatic thermoplastic polyurethane containing at least one pendent functional group selected from the group consisting of hydroxyl and carboxyl functional groups, and at least one heat-activated crosslinking monomer or agent; and said inner layer being formed directly on said outer layer such that said inner layer has an outer surface adjacent an inner surface of said outer layer, said inner layer comprising a thermoplastic polyurethane resin material having at least one ethylenically unsaturated bond in its backbone, at least one pendent hydroxyl group, or a combination thereof, wherein an interfacial chemical bond is formed between at least one of an unreacted functional group of said at least one light-stable aliphatic thermoplastic polyurethane and an unreacted functional group of said at least one heat activated crosslinking monomer or agent of said outer layer and at least one of said at least one ethylenically unsaturated bond and at least one pendent hydroxyl group of said inner layer.
