<p><P>PROBLEM TO BE SOLVED: To provide resin particles retaining no surface active material in or on the surface of the resin particles and having a sharp particle size distribution. <P>SOLUTION: A method of manufacturing resin particles (C) which comprises minute particles (A) attached on the surface of resin particles (B) comprising resin (b) is used, in which, the resin particles (C) are obtained by removing carbon dioxide (X) from a dispersion (X1) by reducing pressure of the dispersion (X1) of minute particles (C1) which is obtained by dispersing a melt liquid of a resin (b) or a solvent solution of the resin (b) in a dispersion medium (X0) comprising carbon dioxide (X) in a liquid or supercritical state in which minute particles (A) are dispersed. It is possible to use a method in which a precursor (b0) of the resin (b) in place of the resin (b) is used and the (b0) in the dispersion (X1) is subjected to polymerization. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
