Procedure

141 g of a 30 percent dispersion of a copolymer of equal parts of methacrylic acid and ethyl acrylate (42 g of solids) were mixed with 328 g of a 30 percent dispersion of film forming copolymer of ethyl acrylate and methyl methacrylate in a ratio of 2:1 (98 g of solids). A suspension of 70 g of talc in 514 g of water was then added. The mixture had a pH of 5.7. (The film forming copolymer has a Tλmax of 29° C. The minimum film forming temperature of the aqueous dispersion is 8° C.).
