Abstract
Abstract An aqueous coating composition having a film-forming binder of a polymer of (a) methyl methacrylate, styrene or a mixture of methyl methacrylate and styrene, (b) a vinyl oxazoline ester of drying oil fatty acids, and (c) and ethylenically unsaturated carboxylic acid; and contains sufficient ammonia or amine to provide a pH of about 7.5-9.5. The composition is a non-air polluting coating composition designed to be used as a finish for automobile and truck bodies.
