摘要： Hollow silicone fine particles have high productivity, low breakability, a narrow particle size distribution and a volume average particle diameter equal to or lower than 1 μm. The hollow particles are made by removing organic macromolecular particles and/or an organic solvent away form inside core-shell particles produced by coating particles made from the organic macromolecular particles and/or the organic solvent with silicone compound that is made from one or more units selected from the group consisting of SiO4/2 unit, RSiO3/2 unit, and R2SiO2/2 unit (wherein R is C1-4 alkyl groups, C6-24 aromatic groups, a vinyl group, a γ-(meth)acryloxypropyl group or organic groups having an SH group(s)), the silicone compound containing R2SiO2/2 unit by 20 mole % or less.
