<P>PROBLEM TO BE SOLVED: To provide novel composite fine particles having novel superior properties and being suitable for cosmetics and light diffusion members. <P>SOLUTION: The composite fine particles are synthesized by a step including steps of: preparing a reaction liquid by mixing spherical silicon fine particles, a solvent, a polymerizable monomer having one unsaturated group, a polymerizable monomer having two or more unsaturated groups, a polymerization initiator, and a dispersion stabilizer together; turning the reaction liquid into droplets; and polymerizing the droplets. A spherical silicon fine particle dispersion may be used as the spherical silicon fine particles and the solvent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
