ABSTRACT:
Coating compositions comprised of a film forming polymer which is the reaction product of (a) a compound containing pendant and/or terminal hydroxyl or epoxy functional groups and (b) citric acid or citric acid anhydride. The coating compositions have enhanced adhesion to galvanized and galvanealed steel substrates without the use of a chrome containing wash primer.
