High solids acrylic dispersion lacquer

A 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 binder consists essentially of about
• (1) 25-45% by weight, based on the weight of the binder, of Polymer A comprising about 90-99.5% by weight, based on the weight of Polymer A, of polymerized methyl methacrylate and about 0.1-5% by weight, based on the weight of Polymer A, of polymerized allyl methacrylate and 0.4-5% by weight, based on the weight of Polymer A, of polymerized alkyl amino alkyl methacrylate and having a weight average molecular weight, measured by gel permeation chromatography, of about 90,000-130,000;
• (2) 5-25% by weight, based on the weight of the binder, of Copolymer B comprising about 40-60% by weight, based on the weight of Copolymer B, of polymerized methyl methacrylate and 40-60% by weight, based on the weight of Copolymer B, of polymerized alkyl acrylate having 6-12 carbon atoms in the alkyl group and having a weight average molecular weight, measured as above, of about 20,000-40,000;
• and
• (3) 40-60% weight, based on the weight of the binder, of 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;
• and
• wherein
• the nonaqueous medium comprises
• (a) an aliphatic solvent which is at 25.degree. C. a nonsolvent for Polymer A and a solvent for Copolymer B;
• and
• (b) a coalescing solvent which at 50.degree. C. and above is a solvent for the binder and at 25.degree. C. is a nonsolvent for the binder.
