A process for preparing composite particles comprising particles and an organic compound in a vessel, comprising the steps of (a) contacting particles with an organic compound in the presence of supercritical carbon dioxide or liquefied carbon dioxide in the vessel; and (b) reducing the internal pressure of the vessel. The composite particles have controlled properties such as water repellency, oil repellency, optical properties, ultraviolet shielding ability, texture, safety, activity, color tone, stability of dispersion and weatherproof, which can be suitably used for paints, ink-jet ink and cosmetics, and the composite particles obtained. |
