Patent ID: 8809416

Claim:
A waterborne coating composition comprising (a) between 10 and 50% by weight of a water-dispersible and hydrophobic polyester resin comprising a reaction product of 30 to 70% by weight of a terephthalate polymer, 5 to 40% by weight of a hydroxyl-functional compound having at least two hydroxyl groups, 1 to 20% by weight of a carboxy-functional compound having at least two carboxyl groups, and 10 to 60% by weight of a hydrophobic compound selected from the group consisting of C 6 -C 24 straight chain or branched fatty acid or triglycerides thereof, and with the hydroxyl-functional compound being present at 1 to 3 times the equivalent of the hydrophobic moiety, (b) between 50 and 90% by weight of a metal salt of a fatty acid, with the amounts being based on the total solids content in the waterborne coating composition, and (c) a base in an amount of between 70% and 130% of the number of carboxylic acid groups in the resin.
