Abstract
PURPOSE: To provide a coating composition for cathode electrodeposition comprising a resin prepared by reacting the reaction product of an epoxy compound with specific carboxyl group-containing copolymer, with an amino group-containing compound and/or an isocyanate group-containing compound.
CONSTITUTION: (A) The reaction product of (a) an epoxy group-containing compound with (b) a carboxyl group-containing butadiene-acrylonitrile copolymer, wherein the amount of the free carboxyl group of (b) is 0.2 W 0.7 equivalent on the basis of 1 equivalent of the epoxy group of (a), is reacted with (B) a partially blocked isocyanate group-containing compound and/or (C) an amino group-containing compound, e.g. ethylene diamine, etc., and the reaction product is compounded with (D) pigments, an antioxidant, etc. to given the desired composition.
EFFECT: The coating films have excellent adhesive property, corrosion resistance, turnover property, impact resistance and selectivity for surface treatment.
