METHOD FOR PRODUCING COMBINED PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing combined particles the individual of which is dispersed excellently and in which a single organic compound particle is not contained.SOLUTION: The method for producing combined particles includes: a step (1) of dry-mixing a coating fine particle, an organic solvent and a mother particle to obtain a mixture; a step (2) of injecting carbon dioxide into a mixture-charged pressure-resistant vessel to combine the mother particle with the coating fine particle in a supercritical or subcritical condition; and a step (3) of removing the organic solvent and the carbon dioxide from the pressure-resistant vessel.
