ABSTRACT:
Coating compositions which may be applied by conventional techniques as well as by electrodeposition are provided by reacting a polyglycidyl ether of a polyphenol with an amino acid containing at least one amine group and one carboxyl group, wherein the amine group of the acid is preferentially reactive with the epoxy groups of the polyglycidyl ether. The resultant product can then be solubilized by neutralizing at least a portion of the acid functionality thereof with an amine or other base. Especially useful amino acids are the aminobenzoic acids.
