摘要： The surface-modified polymethylsilsesquioxane spherical fine particles of this invention comprise polymethylsilsesquioxane spherical fine particles serving as nuclei, and at least one member of an alkyl group having two or more carbon atoms, an alkenyl group, a phenyl group, an epoxy group, an acryloxy group and an amino group is bonded to the surface of a particle. They are prepared by a process comprising the step of carrying out reaction in an aqueous suspension of polymethylsilsesquioxane fine particles in the presence of an alkali catalyst. The surface-modified spherical fine particles can have various organic groups on their surfaces, and are used in various fields such as rubbers, plastics, coating materials, inks, and cosmetics, depending on the types of the organic groups.

摘要： Amorphous spherical silica microparticulates having a specific surface area of 5-50 m2/g and a particle size distribution of 5-1,000 nm are added to toner particles to form an electrostatic image developer which has improved fluidity and cleaning characteristics. On account of the minimized impurity content of the spherical silica microparticulates, the developer is effective for high-quality and high-speed duplication.
