CATHODE-PRECIPITATING ELECTRODEPOSITION COATING COMPOSITION

摘要

A cathode-precipitating electrodeposition coating composition consisting essentially of (A) 100 parts of a high-molecular-weight compound having a molecular weight of 500 to 10,000 and containing an amino group and a carbon-carbon double bond, (B) 3 to 200 parts by weight of a reaction product obtained by reacting an unsaturated carboxylic acid having 3 or 4 carbon atoms with the terminal glycidyl group of a glycidyl compound obtained by reacting a bisphenol with epichlorohydrin, and (C) 0.2 to 20 parts by weight of an oil-soluble manganese salt of a monoester of a 1,2-dicarboxylic acid or a manganese salt of sulfonated or maleinized polybutadiene having a molecular weight of 300 to 3,000.
