Abstract
Thermosetting solvent solution coating compositions are disclosed which form hard and impact resistant baked coatings of good gloss retention on exterior exposure. These compositions comprise a butanol-containing solvent having dissolved therein a solution copolymer obtained by copolymerizing from 55% to 75% of vinyl acetate with from 15% to 40% of C.sub.2 -C.sub.8 hydroxyalkyl acrylate or methacrylate, from 3% to 10% of C.sub.2 -C.sub.4 hydroxyalkyl acrylate or methacrylate, and from about 0.5% to about 5% of copolymerizable monoethylenically unsaturated carboxylic acid in organic solvent medium consisting essentially of a butanol at a solids content of at least 65%. This copolymer is used in admixture with a polyalkoxy-methyl melamine in an amount of from 8% to 20%, based on the mixture.
