<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a resin-containing grain that is not restricted from the sort of the resin to be used as a raw material of the grain, can reduce environmental load, and can protect from the development of rough and large grain, and can have a narrow grain diameter distribution. <P>SOLUTION: The resin-containing grain is produced by obtaining a dispersion 3 by dispersing a raw material 7 containing at least a resin, a supercritical insoluble grain 4, and a supercritical soluble organic compound 5 in a hydrophobic medium 6, feeding the dispersion 3 into a supercritical solution 1, stirring the solution while heating, and then by reducing the pressure of the supercritical solution 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
