COMPOSITE PARTICLE OF ORGANIC FINE PARTICLE AND INORGANIC FINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a composite particle that is a composite particle composed of an organic fine particle and an inorganic fine particle and has sufficiently excellent in mixing uniformity of the composite particle with a material to be mixed.SOLUTION: The composite particle includes an organic fine particle a having a melting temperature of 240°C or higher and an average primary particle size of 100 to 1,500 nm and an inorganic fine particle b and is produced by bonding at least a part of the organic fine particles a and at least a part of the inorganic fine particles b through an organic hydrophobizing agent.SELECTED DRAWING: None
