Abstract
A cathodic electrodeposition paint containing as a binder resin an amine-epoxy resin adduct and a blocked polyisocyanate crosslinker is disclosed. The binder resin and the crosslinker are emulsified in an aqueous medium containing a neutralizing agent with the aid of amine adduct of a monoepoxide compound having a hydrophobic group or block. Not only the amine-monoepoxide adduct functions as a surfactant but also it is deposited electrically and then cured with the crosslinker integrally with the binder resin.
