ABSTRACT:
A color-plus-clear coating system is disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a transparent top coat to the base coat. The transparent top coat composition is a liquid crosslinkable composition comprising a polyepoxide and a polyacid curing agent. The polyepoxide-polyacid curing agent in the transparent top coat provides a composite coating with outstanding gloss and distinctness of image making the composite coating particularly useful as an automotive top coat.
