Abstract
Water-dispersible resins formed from polyglycidyl ethers of polyphenols and N-heterocyclic compounds and containing cationic salt groups are disclosed. The resins can be dispersed or dissolved in water, and can be applied to a wide variety of different substrates by electrodeposition, depositing on the cathode to provide superior corrosion-resistant coatings.
Claims11
A water-dispersible resin which is electrodepositable on a cathode and which contains in the resin molecule cationic salt groups selected from the class consisting of amine salt groups, onium salt groups and mixtures thereof, said resin being prepared from polyglycidyl ethers of polyphenols which contain in the resin molecule N-heterocyclic moieties obtained by reacting said polyglycidyl ether of a polyphenol with an N-heterocyclic material containing a 5 or 6-membered ring and containing ##STR20##
