Abstract
Coating compositions are disclosed comprising a polyester comprising at least two reactive hydroxyl groups, a material comprising at least two functional groups reactive with the hydroxyl groups of the polyester, and a free acid. Methods of using the coatings, methods for refinishing an article with the coatings, and the substrates coated therewith, are also disclosed.
Claims19
A coating composition comprising:
- (a) a polyester comprising at least two reactive hydroxyl groups, wherein the polyester comprises the reaction product of reactants comprising:
- (i) a polycarboxylic acid comprising more than two acid groups per molecule, and
- (ii) a hydroxyl-containing compound comprising no more than two hydroxyl groups per molecule;
- (b) a material comprising at least two functional groups reactive with the hydroxyl groups of the polyester;
- and
- (c) a free acid.

A coating composition comprising:
- (a) a polyester comprising at least two reactive hydroxyl groups;
- (b) a material comprising at least two functional groups reactive with the hydroxyl groups of the polyester (a);
- and
- (c) a free acid,
- wherein the polyester is present in the composition in an amount sufficient to result in a coating having chip resistance improved when compared to a coating deposited at similar conditions from a similar coating composition that does not include the polyester.
