Title:

COMPOSITE PHTHALOCYANINE MICROPARTICLES AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2016/098777

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide: composite phthalocyanine microparticles of a nano-order level, preferably on the order of 100 nm, that are optimal as a coloring material; and a method for producing the same. Provided is a method for producing composite phthalocyanine microparticles, the method being characterized by including a step (1) for preparing a dissolved solution by dissolving at least copper phthalocyanine and titanyl phthalocyanine and/or cobalt phthalocyanine as raw materials in a first solvent, a step (2) for precipitating composite phthalocyanine by mixing the dissolved solution obtained in step (1) with a second solvent that serves as a poor solvent of the abovementioned raw materials, and a step (3) for causing an organic solvent to act on the composite phthalocyanine obtained in step (2). Also provided are composite phthalocyanine microparticles containing at least copper phthalocyanine and titanyl phthalocyanine and/or cobalt phthalocyanine, the composite phthalocyanine microparticles having an aspect ratio of 1.1-2.5 and a particle size of 5-100 nm.
