Zusammenfassung:A composite structure including a first layer, comprising a styrenated polyester, and a polyurethane layer is disclosed. The first layer is a show surface of the composite structure. The polyurethane layer is the reaction product of a resin component and a stochiometric excess of polyisocyanate relative to the polyol. The resin component includes a polyol having a propylene oxide cap of at least 80 percent by weight.
