<p><P>PROBLEM TO BE SOLVED: To provide a method for producing colored resin particles to produce colored resin particles made by efficiently adhering resin fine particles onto the surface of the particles with little environmental loads. <P>SOLUTION: The method for producing colored resin particles includes at least: a step of preparing an oil phase in which at least a resin and a colorant are dissolved or dispersed in an organic solvent; a step of preparing an aqueous phase containing at least a surfactant in an aqueous medium; a step of dispersing the oil phase in the aqueous phase to prepare a colored particle dispersion liquid so as to form core particles; a step of causing resin fine particles to adhere to surfaces of the core particles by adding at least the resin fine particles to the colored particle dispersion liquid, in which the core particles have been formed; a step of removing the solvent from the colored particle dispersion liquid to obtain colored resin particles; a step of cleaning the colored resin particles; and a step of drying the colored resin particles, wherein an inorganic base is dissolved in the colored particle dispersion liquid. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
