실험 절차

683 parts of water, 11 parts of the sodium salt of the sulfuric acid ester of methacrylic acid ethylene oxide adduct (ELEMINOL RS-30, Sanyo Chemical Industries, Ltd.), 83 parts of styrene, 83 parts of methacrylic acid, 110 parts of butyl acrylate and 1 part of ammonium persulphate were introduced into a reaction vessel provided with a stirrer and thermometer, and stirred at 400 rpm/min for 15 minutes to give a white emulsion. This was heated, the temperature in the system was raised to 75° C. and the reaction performed for 5 hours. Next, 30 parts of an aqueous solution of 1% ammonium persulphate was added, and the reaction mixture matured and 75° C. for 5 hours to obtain an aqueous dispersion of a vinyl resin (copolymer of styrene-methacrylic acid-butyl acrylate-sodium salt of the sulfuric acid ester of methacrylic acid ethylene oxide adduct), “particulate emulsion 1.” The volume average particle diameter of particulate emulsion 1 measured by LA-920 was 105 nm. After drying part of “particulate emulsion 1” and isolating the resin, Tg of the resin was 59° C. and the volume average molecular weight was 150000.
