发明名称 Production process of colored fine particulate composition and colored fine particulate composition produced by the process
摘要 A process is provided for producing a colored fine particulate composition by dissolving or dispersing a coloring matter or a coloring matter and charge control agent in a condensation-polymerized resin component and forming the resultant resin composition into fine particles. The coloring matter or the coloring matter and charge control agent are added to a raw material component for the production of the resin component, or to the resin component in a period from initiation to completion of polymerization of the resin component or while the resin component is in a molten state subsequent to the completion of the polymerization, whereby the coloring matter or the coloring matter and charge control agent are dissolved or dispersed in the resulting resin component. A colored composition obtained subsequent to the dissolution or the dispersion is cooled. The colored composition so cooled is then formed into fine particles.
