ABSTRACT:
Resinous coating compositions of low volatile solvent content 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 of outstanding flexibility. 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 solution containing a major proportion of liquid bishydroxy ethyl ether of a bisphenol, alone or together with the corresponding bishydroxy propyl ether. 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 excessive amounts of volatile material.
