Abstract
The present invention provides a polymerizable monomer composition particle and a resin particle, both of which display a narrow particle diameter distribution. A process for producing a resin particle comprises the steps of: passing two liquids through a static type in-line mixer having a liquid-dividing mechanism standing in a static state, wherein the two liquids are formable into two phases including one of the two liquids as a dispersing phase component and the other as a continuous phase component; then passing the two liquids through a high speed shearing type dispersing machine having a liquid-shearing mechanism which revolves at a high speed, thus dispersing a fine liquid drop of the dispersing phase component into the continuous phase component; and forming a resin particle from the resultant liquid drop.
