الإجراء التجريبي
Into a reaction vessel equipped with a stirring rod and a thermometer, 683 parts by mass of water, 16 parts by mass of sodium salt of sulfuric acid ester of ethylene oxide adduct of methacrylic acid, Eleminol RS-30 (manufactured by Sanyo Chemical Industries Ltd.), 83 parts by mass of styrene, 83 parts by mass of methacrylic acid, 110 parts by mass of butyl acrylate, and 1 part by mass of ammonium persulfate were charged, and then stirred at 400 rpm for 15 minutes to thereby obtain a white emulsion. The emulsion was heated to a system temperature of 75° C. and was allowed to react for 5 hours. Then, 30 parts by mass of a 1% by mass aqueous ammonium persulfate solution was added to the reaction mixture, followed by aging at 75° C. for 5 hours, to thereby obtain an aqueous dispersion liquid of a vinyl resin (a copolymer of styrene-methacrylic acid-butyl acrylate-sodium salt of sulfate ester of methacrylic acid-ethylene oxide adduct), i.e. fine resin particle dispersion liquid. The volume average particle diameter of the fine resin particle dispersion liquid was found to be 42 nm, when measured using LA-920 (manufactured by Horiba, Ltd.).
