Patent ID: 8647803

Claim:
A method for producing colored resin particles, comprising: (i) dissolving or dispersing at least a binder resin and a colorant in an organic solvent to prepare an oil phase; (ii) dissolving resin A and a basic compound in an aqueous medium to prepare an aqueous phase, where the resin A has a solubility of less than 2.0 g in 100 g of an acidic aqueous solvent having a pH of 3.0 at a temperature of 25° C. and a solubility of equal to or more than 2.0 g in 100 g of a basic aqueous solvent having a pH of 10.0 at a temperature of 25° C.; (iii) dispersing the oil phase in the aqueous phase to prepare a core particle dispersion liquid in which core particles formed of the oil phase are dispersed; (iv) dispersing fine resin particles in an aqueous medium to prepare a fine resin particle dispersion liquid, and adding the fine resin particle dispersion liquid to the core particle dispersion liquid, prepare thereby obtaining a combined dispersion liquid, wherein the combined dispersion liquid comprises particles each comprising the core particle with the fine resin particles attached; (v) removing the organic solvent from the combined dispersion liquid; and (vi) subsequently washing and then drying the particles each comprising the core particle with the fine resin particles attached, thereby obtaining the colored resin particles.
