Claim Text:
1. A skinned composite comprising a) a substrate, b) an exterior plasticized polymeric skin having a thickness of 0.5 to 2 mm covering at least a portion of the substrate, the exterior plasticized polymer skin comprising a thermoplastic polymer and 25 to 45% by weight of a plasticizer based on the combined weight of the plasticizer and the thermoplastic polymer and further having one or more score lines on an exposed and/or an inner surface; and c) a polyurethane layer interposed between the substrate and the plasticized polymeric skin, wherein the polyurethane layer is the reaction product of a reaction mixture that contains one or more polyisocyanates and one or more isocyanate-reactive compounds that contain two or more isocyanate-reactive groups, wherein the polyurethane has a calculated molecular weight per crosslink of no greater than 1250 as calculated by the formula wherein A is the combined weight, in grams, of all isocyanate-reactive materials that contain at least 2 isocyanate-reactive groups/molecule, including any water, provided to the reaction mixture; B is the combined weight, in grams, of all isocyanate compounds provided to the reaction mixture; C is average functionality of all isocyanate-reactive compounds provided to the reaction mixture that contain at least 2 isocyanate-reactive groups/molecule, including any water; D is the average equivalent weight in grams per hydroxyl group of all isocyanate-reactive compounds provided to the reaction mixture that contain at least 2 isocyanate-reactive groups/molecule, including any water; E is the isocyanate index, calculated as the number of equivalents of isocyanate groups provided to the reaction mixture divided by the number of equivalents of isocyanate-reactive groups provided to the reaction mixture; F is the average functionality of all isocyanate compounds provided to the reaction mixture; and G is the average equivalent weight in grams per isocyanate group of all isocyanate compounds provided to the reaction mixture.
