Abstract
An aminoplast-curable film-forming composition is disclosed. The film-forming 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 composition provides a coating with improved acid etch resistance, making the coating particularly useful as an automotive clear coat.
