ABSTRACT:
Essentially solvent free resinous coating compositions are provided which are sufficiently fluid to permit effective application, and which cure on baking to provide chemically resistant flexible coatings. These are made by copolymerizing monoethylenic monomers including monoethylenic monomer having a functional group reactive with N-methylol functionality and selected from carboxylic acid, hydroxy and amide groups, the copolymerization being carried out in a solvent medium consisting essentially of liquid water insoluble trihydric alcohol having a molecular weight of at least 500. The copolymer solution in trihydric alcohol has added thereto an aminoplast resin to provide a stable solution in which proportions are important so that coatings can be easily applied and cured to provide hard, flexible, adherent, and corrosion resistant films without liberating large amounts of volatile material.
