Abstract
Abstract Described herein is an organic coating composition particularly useful in cathodic electrodeposition comprising a dispersion, solution or suspension of a coating composition characterized by (a) a reaction product of a conjugated fatty acid ester and an acrylic containing monomer, preferably containing oxirane rings; and (b) Formula A within the molecule, being the reaction product of reacting an oxirane ring and an amine; wherein Formula A is: --CH.sub.2 --C(Z)--CH.sub.2 --N═ wherein Z is hydrogen, hydroxyl, alkoxy of 1 to 6 carbon atoms; acyloxy of from 1 to 6 carbon atoms; (═O, as in a ketone), --OR'].sub.n H; --OR'].sub.n OH, and --OR'(CH.sub.2 OH)].sub.n OH, wherein R' is a saturated alkylene group of from 2 to 4 carbon atoms and n is a number from 1 to 6. Also described is a method of electrodepositing coating compositions containing said adducts onto a cathode.
