Abstract
An object of the present invention is to find a cationic electrodeposition coating composition excellent in throwing power, anti-GA gas pinhole properties, and anti-corrosion properties, and to provide a coated article excellent in these coating film properties. The present invention provides a cationic electrodeposition coating composition containing an amino-containing epoxy resin (A), a blocked polyisocyanate curing agent (B), and a pigment (C), the amino-containing epoxy resin (A) being obtained by reacting an epoxy resin (A1), a polyphenol compound (A2), a dimer acid diglycidyl ester (A3), and an amine compound (A4).
