Abstract
A coating composition is used to form a clearcoat layer of a film system including a basecoat layer and the clearcoat layer. The coating composition includes a carbamate functional polymer, a cross-linking agent reactive with the carbamate functional polymer, and an acid functional polymer substantially non-reactive with the carbamate functional polymer and the cross-linking agent. The acid functional polymer has an acid value of at least 50 mg KOH/g and contributes to an increased resistance to acid etch of the clearcoat layer. The acid functional polymer also contributes to an increased intercoat adhesion of the basecoat layer and the clearcoat layer thereby decreasing a possibility of separation/delamination of the basecoat layer and the clearcoat layer.
