ABSTRACT:
A low temperature curing solution coating composition is disclosed for the protection of solvent-sensitive thermoplastic moldings. In these compositions, a solvent medium consisting essentially of alcoholic solvents has dissolved therein a self-curing solution copolymer of monoethylenically unsaturated monomers containing an ether of an N-methylol functional monomer, especially isobutoxymethyl acrylamide. This solution is catalyzed with from 0.5% to 2.0%, based on the weight of the copolymer, of sulfuric acid. The catalyzed compositions are stable and cure at 150.degree. F. to 200.degree. F. without damaging the thermoplastic moldings.
