PCT No. PCT/JP97/02379 Sec. 371 Date Mar. 10, 1998 Sec. 102(e) Date Mar. 10, 1998 PCT Filed Jul. 9, 1997 PCT Pub. No. WO98/02494 PCT Pub. Date Jan. 22, 1998This invention provides a cationic electrodeposition coating composition comprising (A) a resin prepared by reacting an epoxy- or carboxyl-containing acrylic polymer, a bisphenol compound and a bisphenol diglycidyl ether-type epoxy resin to produce an epoxy-containing resin and introducing thereinto cationic groups and (B) a hydroxyl- and amino-containing acrylic resin, the resins (A) and (B) being crosslinked and cured by urethanation reaction with (C) an isocyanate crosslinking agent component. The cationic electrodeposition coating composition of the invention is excellent in curability and in corrosion resistance of the cured coating film. |
