Title: Electrodeposition of N-heterocyclic-containing resins

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.
