Abstract

PURPOSE:To save energy and time by quenching a liquid dispersion of a colorant, a resin for dispersing said colorant, and a liquid carrier and forming finely dispersed particles. CONSTITUTION:The cooling is executed by passing cooling water or a cooling medium through a dispersing machine, such as a roll mill or a media dispersing machine, to be used for dispersing a colorant, such as pigments or dyes. A mixture of the colorant, such as pressed cake or pigments, and the liquid carrier, such as a nonpolar solvent, is fed to the dispersing machine, while it is heated and stirred, and dispersed and then, quenched, thus permitting particle size to be easily controlled and the dispersion of the fine particles of the colorant dispersed in the thermoplastic resin to be dispersed in the nonpolar solvent, and accordingly, energy and time to be saved.
