Abstract

An electrodeposition coating composition is described comprising: (a) an aqueous dispersion of a water-dispersible, electrically-depositable, at least partially neutralized cationic resin, and (b) polymer microparticles, said polymer particles being prepared by: PA1 (1) blending an acid-neutralized tertiary amino-functional acrylic polymer and a polyepoxide, PA1 (2) dispersing the blended mixture in an aqueous medium to form a dispersion of microparticles of the blended mixture, and PA1 (3) heating the dispersion to crosslink the acrylic and polyepoxide in the microparticles.
