<p><P>PROBLEM TO BE SOLVED: To provide acrylic resin fine particles capable of being used for an ion-less use, and exhibiting a high weather resistance and waterproof property in the case of using them as a coating material, etc. <P>SOLUTION: The acrylic resin fine particles do not contain a surfactant and suspension stabilizer. The acrylic fine particles preferably have≤1μm mean particle diameter,≤5 % CV value of the particle diameter and≤1.25 sphericity. The acrylic resin fine particles can be produced by subjecting the acrylic resin such as a polymethyl methacrylate and liquid which does not dissolve the acrylic resin in a normal temperature and pressure under a supercritical state. <P>COPYRIGHT: (C)2004,JPO</p> |
