High solids coating compositions containing liquid bishydroxy propyl ether of a bisphenol

A fluid resinous coating composition containing less than about 30% of volatile organic solvent and which cures on baking, said coating composition consisting essentially of a mixture of:

• 1. a copolymer of monoethylenic monomers including from about 5-20% of monoethylenic monomer having a functional group reactive with the N-methylol group and selected from carboxylic acid, hydroxy, and amide groups, said copolymer being produced by copolymerization in an organic solvent solution containing a major proportion of component (2) below;
• 2. liquid bishydroxy propyl ether of a bisphenol formed by reacting propylene oxide with a bisphenol;
• and
• 3. an aminoplast resin;
• said copolymer constituting from about 4.5% to 35% of the mixture, the bishydroxy propyl ether constituting from about 20% to 40% of the mixture, and the balance of the mixture of the three components consisting essentially of aminoplast resin, there being at least about 0.8 parts of aminoplast resin per part of copolymer, and said copolymer being present in an amount of from about 15-80% of the weight of the bishydroxy propyl ether.
