Cathodic electrodeposition compositions employing fatty acid derivatives

Abstract

Described is an organic coating composition particularly useful in cathodic electrodeposition comprising a dispersion, solution or suspension of a coating composition containing an acrylic polymer; the coating composition characterized by being the product of a reaction with a fatty acid and also containing Formula A within said polymer molecule, and said Formula A group being derived from an oxirane ring wherein the coating composition has substantially no oxirane rings therein: Formula A: --CH.sub.2 --C (Z)--CH.sub.2 --N.dbd. wherein Z is hydrogen, hydroxyl, alkyl ether of 1 to 6 carbon atoms; acyloxy of from 1 to 6 carbon atoms; (.dbd.O, as in a ketone) --OR'].sub.n H; --OR'].sub.n OH, and --O-R'(CH.sub.2 OH)].sub.n OH where R' is saturated alkylene of from 2 to 4 carbon atoms and n is from 1 to 6.
