Into a reaction vessel to which a stirring rod and a thermometer had been set, 683 parts by mass of water, 11 parts by mass of sodium salt of sulfuric acid ester of ethylene oxide adduct of methacrylic acid (“ELEMINOL RS-30,” product of 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 mss of ammonium persulfate were charged, and then stirred at 400 rpm for 15 min to thereby obtain a white emulsion. The resultant 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 thereto, followed by aging at 75° C. for 5 hours, to thereby obtain an aqueous dispersion liquid [fine resin particle dispersion liquid 1] of a vinyl resin (a copolymer of styrene-methacrylic acid-sodium salt of sulfuric acid ester of ethylene oxide adduct of methacrylic acid).
