US 6,784,236 B2 · Electrodeposition coating composition

Abstract

The present invention provides an electrodeposition coating composition which has an excellent film forming property and which is excellent in performances such as a smoothness and an anti-corrosion performances even after storing over a long period of time. The electrodeposition coating composition comprises an ester compound selected from the group consisting of: (a) a diester compound of polyoxyalkylene glycol and aliphatic monocarboxylic acid, (b) a diester compound of polyoxyalkylene alkyl ether monoalcohol and aliphatic dicarboxylic acid and (c) a polyester compound obtained by reaction of aliphatic glycol having 2 or 3 carbon atoms, aliphatic dicarboxylic acid and aliphatic monoalcohol.
