Claims
- 1. A curable coating composition comprising the following components:
- (a) a carboxyl functional adduct comprising the reaction product of the following reactants:
- (i) a compound, polymer or oligomer containing pendant and/or terminal hydroxyl or epoxy functional groups; and
- (ii) a material selected from the group consisting of citric acid anhydride and citric acid,
- wherein the carboxyl functionality of the adduct is in a terminal and/or pendant position and is derived from the reaction of the hydroxyl functional groups with citric acid anhydride and/or the reaction of the epoxy functional groups with citric acid; and
- (b) an anhydride functional curing agent.
- 2. The curable coating composition of claim 1 wherein reactant (i) is an acrylic polymer containing pendant and/or terminal hydroxyl or epoxy functional groups.
- 3. The curable coating composition of claim 1 wherein reactant (i) is a polyester polymer containing pendant and/or terminal hydroxyl or epoxy functional groups.
- 4. The curable coating composition of claim 1 wherein reactant (i) is a polyglycidyl ether of a cyclic polyol containing pendant and/or terminal epoxy groups.
- 5. The curable coating composition of claim 1 wherein reactant (i) is an acrylic monomer containing pendant and/or terminal hydroxyl groups.
- 6. The curable coating composition of claim 1 further comprising at least one pigment.
