摘要： Cathodic electrodeposition paints are rendered hardly susceptible to oil droplet-induced craters by incorporating an amine-modified acrylic copolymer of t-butyl (meth)acrylate with a hydroxyl group-containing monomer and an oxirane ring-containing monomer in the form of an aqueous emulsion. The amine-modified acrylic copolymer may be an adduct with a half blocked organic diisocyanate. The paint gives a cured film substantially free from oil droplet-induced craters and having a good adhesion to an overcoating and a good surface smoothness.
