ABSTRACT:
Essentially solvent-free resinous coating compositions are provided which are sufficiently fluid to permit effective application, and which cure on baking at low temperature to provide hard stain- and detergent-resistant 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 tetrahydric adduct of propylene oxide with pentaerythritol having a molecular weight of at least about 400. The copolymer solution 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 the desired characteristics without liberating large amounts of volatile material.
