Abstract
Polyepoxide resins are adducted with amines and the adducts are then reacted with cyclic dicarboxylic acid anhydrides. The resulting resinous products when salted with an amine are water soluble or water dispersible. The resinous solutions or dispersions can be formulated into coating compositions particularly useful for metal substrates.
