<p><P>PROBLEM TO BE SOLVED: To provide resin particles having a sharp particle size distribution and not having a hydrophilic component left in or on the surface of the resin particles; and to provide a method for producing the resin particles by using carbon dioxide in a supercritical state. <P>SOLUTION: The method for producing the resin particles comprises dispersing a molten liquid of a resin (b) or a solvent solution of the resin (b) in a dispersion medium (XO) obtained by dispersing fine particles (A) in carbon dioxide (X) in a liquid or super critical state, and containing a dispersion stabilizer (D) having at least one group of a dimethylsiloxane group and a fluorine-containing functional group to afford a dispersion (XI) of the fine particles (C1), and removing the carbon dioxide (X) in the liquid or supercritical state by reducing the pressure to afford the resin particles (C) wherein the fine particles (A) is attached to the surfaces of the resin particles (B) comprising the resin (b). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
