Abstract
An object of the present invention is to find a method for producing a cationic electrodeposition coating composition that is excellent in storage stability, low-temperature curability, finished appearance, and corrosion resistance, and to provide a coated article excellent in these properties. The method for producing a cationic electrodeposition coating composition comprises mixing three components, i.e., an aqueous dispersion of an amino group-containing epoxy resin (A), an aqueous dispersion of a blocked polyisocyanate compound (B), and a pigment dispersion paste (C), wherein the aqueous dispersion of a blocked polyisocyanate compound (B) comprises a blocked polyisocyanate compound (b) and an emulsifier.
