Procedure

In a mixed solution of 75 parts of dodecyl methacrylate and 25 parts of methyl methacrylate, 0.1 parts of azobisdimethylvaleronitrile was dissolved. In the mixture, a mixed solution of 2.0 parts of sodium dodecylbenzenesulfonate and 300 parts of distilled water was added and, after stirring using a homomixer at 10000 rpm for 4 minutes, it was passed through a homogenizer twice at a pressure of 300 kg/cm2 to obtain a stable dodecyl methacrylate/methylmethacrylate preliminary dispersion. This dispersion was then charged into a separable flask equipped with a stirrer, a condenser, a thermocouple and a nitrogen inlet, and the mixture was raised to an internal temperature of 80° C. in a nitrogen gas flow and stirred for 3 hours for radical polymerization to obtain a dodecyl methacrylate/methyl methacrylate copolymer particle dispersion (hereunder referred to as P-2).
