摘要： 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.
