On the other hand, magnesium aluminate metasilicate was dispersed in water as inorganic fine particles together with a very small amount of a surfactant (Surfinol 440, mfd. by Nissin Kagaku Kogyo K.K.), and the resulting dispersion, methyl methacrylate, butyl methacrylate, butyl acrylate and 3-trimethoxysilylpropyl methacrylate were mixed in the weight ratio of 3:2:3:2:0.2. The resulting mixture was treated with nitrogen to replace the air, after which potassium persulfate was added and emulsion polymerization was carried out at 60° C. for 8 hours. After completion of the reaction, the concentration was adjusted with water to prepare an (inorganic fine particles)-coated organic fine particles dispersion F (40 wt %) in which magnesium aluminate metasilicate fine particles had been formed on the surfaces of the acrylic copolymer resin fine particles.
