ABSTRACT:
A color-plus-clear coating system is disclosed. A pigmented or colored basecoat is first applied to a substrate followed by the application of a transparent topcoat to the basecoat. The transparent topcoat composition is a crosslinkable composition comprising (1) a material containing a plurality of carbamate and/or urea functional groups and (2) an aminoplast crosslinking agent. The topcoat composition provides a composite coating with improved acid etch resistance, making the composite coating particularly useful as an automotive topcoat.
