Abstract
A cathodic electrodeposition paint containing a cationically modified epoxy resin and a crosslinker dispersed in an acidic aqueous medium is disclosed which contains an auxiliary resin component which is capable of improving the surface smoothness of the cured paint films and which is a reaction product produced by reacting a t-alkylphenol novolac epoxy resin with an amount of an active hydrogen compound sufficient to open all epoxy rings. When the thus produced auxiliary resin has a hydroxyl group, reaction thereof with a lactone or alkylene oxide, to graft a soft segment to the auxiliary resin improves not only the surface smoothness but also the impact strength of the paint films.
