Abstract
A method for the manufacture of a copolymer coating composition comprises copolymerizing two or more copolymerizable monomers in dispersion in an aqueous medium in the presence of a surfactant to provide a dispersion of the copolymer containing between 30% and 70% by weight of solids then adding the copolymer dispersion with agitation to a sufficient amount of a volatile organic solvent for the copolymer to provide a water-in-solvent emulsion containing between 10% and 25% by weight of copolymer. Substrates coated with the copolymer coating compositions are also disclosed.
