ABSTRACT:
A cationic electrophoretic coating composition comprising:
(A) a water-soluble or water-dispersible resin prepared by neutralizing with an acid addition products of partially blocked polyisocyanate and the reaction products, said reaction products being prepared by reacting at least one of fatty acid and polyamide with adducts prepared by being allowed an epoxy resin to react with a basic amino compound, and
(B) at least one of addition polymers of at least one of ethylene oxide and propylene oxide and derivatives of the addition polymers, the polymers and the derivatives thereof having a number average molecular weight of 500 to 10,000 and having a solubility of up to 60 parts by weight in 100 parts by weight of water at 25.degree. C.
