Patent ID: 8629218

Claim:
A curable film-forming composition comprising: a) a film-forming resin; and b) a crosslinking agent; wherein the film-forming resin comprises a polymer containing functional aromatic groups derived from functional aromatic acids having the structure: wherein substituents R 1 to R 7 are each independently —H; —OH; C 1 to C 18 alkyl or aryl; —OR; —OCOR; —OCO 2 R; —NH 2 ; —NHR; —NHRR′; —NHCOR; —NRCOR′; —SH; —SR; —SCOR; where R and R′ are each independently C 1 to C 18 aryl or alkyl; and provided that at least one of the substituents in each structure is attached to the aromatic ring through an —O—, —N—, or —S— linkage; and wherein the polymer is further prepared from an ethylenically unsaturated, beta-hydroxy ester functional monomer selected from the group consisting of: a) a reaction product of an ethylenically unsaturated, epoxy functional monomer and a saturated carboxylic acid having 13 to 20 carbon atoms; and b) a reaction product of an ethylenically unsaturated acid functional monomer and an epoxy compound which contains at least 5 carbon atoms and which is not polymerizable with the ethylenically unsaturated acid functional monomer.
