摘要：
The present invention provides a cationic electrodeposition coating composition comprising: a specific amino group-containing modified epoxy resin (A); a blocked polyisocyanate curing agent (B); a water-soluble zirconium compound (C); and sulfamic acid, wherein the water-soluble zirconium compound (C) is present in an amount of 10 to 10,000 ppm, calculated as the mass of the elemental zirconium, relative to the mass of the cationic electrodeposition coating composition.
