ABSTRACT:
A water reducible epoxy ester is prepared by reacting an epoxy resin, preferably a diglycidyl ether of bisphenol A, with a monocarboxylic acid (C.sub.8 -C.sub.18) and a dibasic acid (e.g., azelaic acid) followed by reaction with trimellitic anhydride and neutralization of free carboxyl groups. This material is dispersed in an aqueous vehicle, applied to a metal substrate, and baked.
