Reaktionsschritte

A mixed solution of the whole amount of the above-described resin grain dispersion (as seed) and 10 g of Dispersion Stabilizing Resin (Q-1) was heated to a temperature of 60° C. under nitrogen gas stream with stirring. To the mixture was added dropwise a mixture of 85 g of benzyl methacrylate, 15 g of methyl acrylate, 1.0 g of methyl 3-mercaptopropionate, 0.8 g of AIVN and 200 g of Isopar H over a period of 2 hours, followed by further reacting for 2 hours. Then 0.8 g of AIVN was added to the reaction mixture, the temperature thereof was raised to 70° C., and the reaction was conducted for 2 hours. Further, 0.6 g of AIVN was added thereto, followed by reacting for 3 hours. After cooling, the reaction mixture was passed through a nylon cloth of 200 mesh to obtain a white dispersion which was a latex of good monodispersity having a polymerization ratio of 98% and an average grain diameter of 0.25 μm.
