ABSTRACT:
A novel polyester is provided comprising the reaction product of: (1) an acid functional polyester which is prepared from: (a) a material of the structure: ##STR1## wherein X is a lower alkyl group having from about 1 to about 4 carbon atoms, and R and R' are independently lower alkylene groups having from about 1 to about 4 carbon atoms; (b) a polyol different from (a); and (c) a polyacid; and (2) a monoepoxide containing from about 3 to 20 carbon atoms. The reaction product is carbamoylated. The carbamoylated polyester can be present in a film-forming composition also having a carbamate functional acrylic polymer; and an aminoplast crosslinking agent. Also such a film-forming composition can be a clear coat in a multi-component composite coating composition.
