Abstract
An acid-neutralizable cationic electrodepositable resin composition comprising as a film-forming ingredient the reaction product of PA1 (A) an epoxy resin or an adduct of an epoxy resin with a primary amine and/or a secondary amine, PA1 (B) an amino-terminated condensation product between a maleinized fatty acid and a polyamine, and PA1 (C) a partially blocked polyisocyanate compound. The composition can form a cathodically electrodepositable aqueous bath by being neutralized with an acid, and can give a coated film having superior surface smoothness and corrosion resistance with a high throwing power.
