Procedure

In a mixed solution of 75 parts of dodecyl methacrylate and 25 parts of methyl methacrylate there was dissolved 0.1 part of 2,2′-azobis(2,4-dimethylvaleronitrile). To this there was then added a mixed solution containing 2.0 parts of sodium dodecylbenzenesulfonate and 300 parts of distilled water, and after stirring for 4 minutes at 10,000 rpm with a homomixer, it was passed twice through a homogenizer at 30 MPa pressure to obtain a stable dodecyl methacrylate/methyl methacrylate preliminary dispersion. This was charged into a separable flask equipped with a stirring blade, condenser, thermocouple and nitrogen inlet, the internal temperature was raised to 80° C. under a nitrogen stream and the mixture was stirred for 3 hours for radical polymerization, to obtain a dodecyl methacrylate/methyl methacrylate copolymer particle dispersion (hereunder referred to as “B-4”).
