Vorschrift

A reactor equipped with a stirring rod and a thermometer was charged with: 683 parts by mass of water; 16 parts by mass of a sodium salt of sulfuric acid ester of methacrylic acid ethylene oxide adduct (ELEMINOL RS-30, manufactured by Sanyo Chemical Industries, Ltd.); 83 parts by mass of styrene; 83 parts by mass methacrylic acid; 110 parts by mass of butyl acrylate; and 1 part by mass of ammonium persulfate, which was stirred at 400 rpm for 15 minutes, and a white emulsion was obtained. The emulsion was heated so that the system has a temperature of 75° C. and was subjected to a reaction for 5 hours. Further, 30 parts by mass of a 1-% by mass aqueous solution of ammonium persulfate were added, which was aged at 75° C. for 5 hours, and an aqueous dispersion solution of a vinyl resin (a copolymer of styrene-methacrylic acid-butyl acrylate-sodium salt of sulfate ester of methacrylic acid ethylene oxide adduct) [Resin Fine Particles Dispersion 1] was obtained. A volume-average particle diameter of [Resin Fine Particles Dispersion 1] was measured by LA-920 (manufactured by Horiba Ltd.), and it was found to be 9 nm.
