ABSTRACT:
Flexible, aminoplast-curable film-forming compositions and multi-component composite coating compositions comprising at least one pigmented or colored base coat and at least one transparent clear coat are disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a clear coat to the base coat. Both the colored base coat and the clear coat are flexible, curable film-forming compositions having an aminoplast crosslinking agent, and the base coat and optionally the clear coat has carbamate functional polymers. The flexible, multi-component composite coating compositions provide improved durability, water spotting resistance, and/or acid etch resistance, making the composite coatings particularly useful for plastic automotive parts.
