CA 1339166
A coating composition useful for a finish for automobiles and trucks in which the film forming binder contains reactive binder components of about (a) 25-90% by weight, based on the weight of the binder, of an acrylic polymer having at least two reactive anhydride groups composed of polymerized monomer of an ethylenically unsaturated anhydride and polymerized monomer from the group consisting of alkyl methacrylate, alkyl acrylate and any mixtures thereof, wherein the alkyl groups have 1-8 carbon atoms and the polymer has a weight average molecular weight of about 2,000-50,000; (b) 5-50% by weight, based on the weight of the binder, of a gycidyl component having at least two reactive glycidyl groups; (c) 5-40% by weight, based on the weight of the binder, of a monomeric or oligomeric anhydride component; and the composition contains about 0.1-5% by weight, based on the weight of the binder, of a catalyst.
