ABSTRACT:
Heat-hardenable synthetic resins which are water soluble upon partial or total neutralization comprising the reaction products of epoxy groups containing unsaturated diene polymers and amine compounds, graft polymerized with alpha, beta-ethylenically unsaturated monomers which are free from epoxy reactive groups, the homopolymers of the monomers having a glass transition temperature of over 320.degree. K. A process of preparing the heat-hardenable resins is also described. The synthetic resins can be employed as binders for cathodically depositable aqueous coating compositions to provide coatings which will cure at relatively low temperatures and relatively short curing times to provide smooth and hard films having good resistance to water, chemicals, and corrosion; and which adhere well to the coated surface.
