Abstract
It is an object of the present invention to provide a sulfonium group- and propargyl group-containing cationic electrodeposition coating composition whose curability can be enhanced without using any heavy metal-containing metal catalyst and which is further excellent in storage stability in a stationary state as well as a method of stabilizing cationic electrodeposition coating compositions. A cationic electrodeposition coating composition comprising a sulfonium group- and propargyl group-containing resin composition and a copper catalyst, the copper catalyst being a long-chain alkylsulfonic acid copper salt.
