Reaction Steps

A polymerizable monomer consisting of 80.5 parts of styrene and 19.5 parts of n-butyl acrylate (Tg of the copolymer obtained by copolymerizing these monomers=55° C.), 0.3 part of polymethacrylic acid ester macromonomer (manufactured by Toagosei Co., Ltd.; trade name: AA6; Tg=94° C.), 0.5 part of divinyl benzene, 1.2 parts of t-dodecyl mercaptan, 7 parts of carbon black (manufactured by Mitsubishi Chemical Corporation; trade name: #25B) , and 7 parts of an antistatic resin (manufactured by Fujikura Kasei Co., Ltd.; trade name: FCA-626M were wet-ground using a media-type wet-grinding machine to prepare a polymerizable monomer composition for the core.
