Abstract

Pigment dispersion resins for use in cathodic electrocoat paint systems are the reaction products of (A) the reaction product of an aromatic diglycidyl ether and a bis-aryl alcohol or aromatic diol; (B) a primary amine which includes a diamine, an amino alcohol, an aminopolyalkoxy alcohol, a fatty amine, or any mixture thereof; and (C) a monoepoxide. In one embodiment, the fatty amine is provided in an effective amount to eliminate the necessity of the inclusion of the monoepoxide.
