ABSTRACT:
A water-reducible acrylic enamel coating composition capable of being substantially completely cured at a relatively low temperature, such as about 250.degree. F. and containing a water-miscible partially etherified melamine formaldehyde cross-linking agent and an acrylic copolymerization product of about 3% to about 8% of an unsaturated carboxylic acid, about 10% to 30% of a hydroxy functional monomer and about 62% to 87% of a nonfunctional monomer. The acrylic copolymer is further characterized as having a glass transition temperature of about -10.degree. C. to 45.degree. C. and a molecular weight of about 2,000 to about 100,000. The aminoplast resin preferably is only partially etherified and contains about 10% to about 30% by weight reactive methylol groups.
