Abstract: A process for making high solids acrylic dispersion lacquer coating composition having an acrylic polymer binder content of about 25-45% by weight in a nonaqueous medium; wherein the acrylic polymer is a blend of(1) Polymer A of methyl methacrylate and a polymerized monomer of allyl methacrylate, alkyl amino alkyl methacrylate or mixtures thereof;(2) Copolymer B of methyl methacrylate and an alkyl acrylate having 6-12 carbon atoms in the alkyl group; and(3) A graft copolymer of Polymer A which forms a backbone of the graft copolymer and Copolymer B attached to the backbone which forms side chains of the graft copolymer; andwherein the nonaqueous medium is a blend of(a) an aliphatic solvent which at 25.degree. C. is a nonsolvent for Polymer A and a solvent for Copolymer B; and(b) a coalescing solvent for the binder;the composition is useful as an exterior finish for automobiles and trucks.

Abstract: An aqueous dispersion lacquer composition of a binder in an aqueous medium; the binder is comprised of(1) a dispersed Polymer A of methyl methacrylate that can contain small amounts of adhesion promoting monomers such as diethyl amino ethyl methacrylate and other monomers that lower the glass transition temperature of the poolmer such as butyl methacrylate or butyl acrylate;(2) a dispersant Polymer B of methyl methacrylate, optionally, styrene, an alkyl acrylate or an alkyl methacrylate and an ethylenically unsaturated carboxylic acid; and(3) a graft copolymer of the dispersed Polymer A and the dispersant Polymer B; andThe composition contains sufficient base such as amine or ammonium hydroxide to provide a pH of about 7-9 and usually contains conventional plasticizers, pigments and other additives as are used in aqueous coating compositions.The composition is used an an exterior finish for automobile and truck bodies.
