Procedure

Water and octylphenylhydroxypolyoxyethylene were mixed in a glass reaction vessel fitted with a stirrer, and the mixture was heated to 70° C. Butyl acrylate, styrene and the crosslinking monomer were added, followed by potassium persulfate in aqueous solution. The resulting mixture was stirred at a rate of the order of 250 rpm, while the temperature was maintained at 70° C. The polymerization time was 4 hours. The resulting latex had a solid content of 22.8% by weight, and a mean particle diameter of 330 nm.
