Base solubilization of an azole-functional resin and electrodeposition of such solubilized resin

A method of imparting water solubility or dispersibility to a reaction product comprising:

• mixing the reaction product with a base and water, the amount of base being sufficient to impart water solubility or dispersibility to the reaction product, wherein the product results from the reaction of
• (A) a N-heterocyclic compound selected from the group consisting of a triazole, a tetrazole and a mixture thereof, said N-heterocyclic compound substituted on at least one carbon atom in the N-heterocyclic ring by a group of the formula --X).sub.n wherein
• X represents an alkylene group containing from 1 to 6 carbon atoms optionally halogen substituted, a cycloalkylene group containing from 5 to 8 carbon atoms optionally halogen substituted, or a phenylene group optionally substituted by halogen and/or an alkyl group containing from 1 to 6 carbon atoms, and n represents 0 or 1, and
• (B) a polyepoxide containing 1,2-epoxy groups, wherein the ratio of equivalents of said N-heterocyclic compound to epoxide equivalents of said polyepoxide is from about 0.5:1.0 to about 1.5:1.0.
