Cationic electrodeposition coating composition containing long-chain alkyl sulfate copper salt component and method of producing the same

Abstract

The present invention is to provide a method by which a cationic electrodeposition coating composition comprising, as a basic resin, a sulfide-modified epoxy resin having a propargyl group and an unsaturated double bond-containing hydrocarbon group can be improved in curability without using a metal catalyst containing a hazardous heavy metal. The cationic electrodeposition coating composition of the invention comprises a long-chain alkyl sulfate ester copper salt component and a sulfide-modified epoxy resin having a propargyl group and an unsaturated double bond-containing hydrocarbon group.
