COATING COMPOSITION AND METHOD FOR FORMING COATING FILM USING SAME

摘要

The problem that the present invention should solve is to provide cationic electrodeposition paint excellent in throwing properties in a gap part (clearance coating properties), edge anticorrosion properties and finish properties. The present invention provides a cationic electrodeposition paint composition including specific amino group-containing epoxy resin (A), blocked polyisocyanate (B) obtained by reacting a polyisocyanate compound and an active hydrogen-containing component containing propylene glycol, and cationic electrodepositing gelled microparticulate polymer (C), in which acrylic copolymer containing a hydrolyzable alkoxysilane group and a cationic group is cross-linked, in from 0.1 to 20 parts by mass relative to total 100 parts by mass of solid contents of the amino group-containing epoxy resin (A) and the blocked polyisocyanate compound (B).
