Abstract
In a method for producing composite particles containing polymer particles and silica particles that adhere to the polymer particles, the composite particles are obtained by subjecting a polymerizable monomer to aqueous suspension polymerization in a presence of silica particles and a cellulose compound adsorbing onto the silica particles. The composite particles contain the polymer particles, the silica particles that adhere to surfaces of the polymer particles, and the water-soluble cellulose compound.

A method for producing composite particles containing polymer particles and silica particles that adhere to the polymer particles, comprising:
- a polymerization step of subjecting a polymerizable monomer to aqueous suspension polymerization in a presence of silica particles and a water-soluble cellulose compound adsorbing onto surfaces of the silica particles so as to obtain the composite particles;
- and
- an adsorption step of treating the silica particles with the water-soluble cellulose compound before the polymerization step so as to adsorb the water-soluble cellulose compound onto the surfaces of the silica particles.
