Abstract
Abstract A COPOLYMER IS DISSOLVED IN A NONAQUEOUS DISPERSION CONSISTING ESSENTIALLY OF ACTIVE ETHENIC MONOMERS COPOLYMERIZED IN THE PRESENCE OF AN ALKYLATED AMINO RESIN. ACTIVE ETHENIC MONOMERS OF THE DISPERSION ARE FREE OF FUNCTIONAL HYDROXY GROUPS AND AT LEAST ONE HAS A FUNCTIONAL EPOXY GROUP. THECOPOLYMER HAS FUNCTIONAL GROUPS CAPABLE OF REACTING WITH THE ALKYLATED AMINO RESIN AND THE EPOXY GROUPS DURING FINAL FILM CURING. CONVENTIONAL TECHNIQUES ARE USED TO APPLY THE MIXTURE TO VEHICLE BODIES WHICH THEN ARE HEATED TO DRIVE OFF THE DISPERSION MEDIUM AND SOLVENT AND CURE THE REMAINING INGREDIENTS INTO A GLOSSY, DRABLE THERMOSETTING FILM.
