ABSTRACT The invention is a water dispersible epoxy resin composition comprising: A) the reaction product of one or more polyepoxides optionally, one or more poly (aromatic hydroxy) containing compounds optionally, one or more chain terminators, and one or more nominally difunctional C12-36 fatty acids or a dimer of an unsaturated, fatty acid; wherein the composition further comprises: B) a sufficient amount of a surfactant to form a stable dispersion of the epoxy resin in water wherein the surfactant comprises an alkyl aryloxy poly(propyleneoxy) poly(ethyleneoxy) ethanol or a C12-36 hydrocarboxy poly(propyleneoxy) poly(ethyleneoxy) 38,977-F ethanol wherein the hydrocarboxy moiety is the residue of a C12-36 fatty alcohol or fatty acid. In another aspect the invention is a high solids aqueous emulsion of such epoxy resin reaction product and surfactant. In yet another aspect, the invention is a coating composition comprising an aqueous emulsion containing the hereinbefore described epoxy resin coating composition, and a water-soluble dispersible, or emulsifiable curing agent or hardener for such epoxy resin composition. 38,977-F
