Abstract:
A cationic resin composition comprising the following components:(A) an amino group-containing epoxy resin which is prepared by adding an amino group-containing compound (a-2) to an epoxy resin (a-1) having an epoxy equivalent of 400 to 3000, (B) a polyol-modified amino group containing epoxy resin which is prepared by making an epoxy resin (b-1) having an epoxy equivalent of 180 to 2500 react with an amino group-containing compound (b-2) and with a polyol compound (b-3) obtained by adding caprolactone to a compound having plural active hydrogen groups, and (C) a blocked polyisocyanate curing agent, component (A) being 40 to 70% by weight, component (B) being 4 to 40% by weight, and component (C) being 10 to 40% by weight, based on the total solid content of components (A), (B) and (C); and in said amino group-containing epoxy resin (A), the weight ratio of (a-1)/(a-2) being within a range of 90/10 to 60/40; and the resins (A) and (B) being neutralized with an acidic neutralizer.
