摘要：
A polyurethane coated polyvinyl chloride or co-polymer which resists discoloration is provided by coating the substrate surface with an aqueous dispersed polyurethane treated with a mono-acid halide, mono-acid anhydride, carbethoxy cyclic imide or monoisocyanate. The coated composite even when subjected to temperatures in excess of 100 degrees C. for extended periods resists discoloration and remains thermo-color stable with extended use.
