SOLID SOLUTION PIGMENT NANOPARTICLE DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide solid solution pigment nanoparticles having a homogeneous solid-solution ratio.SOLUTION: There are provided solid solution pigment nanoparticles prepared by precipitating at least two types of pigments by mixing at least one type of pigment solution in which at least two types of pigments are dissolved in a solvent or at least two types of pigment solutions in which at least one type of pigment is dissolved in a solvent and a pigment precipitation solvent. The precision of the solid solution ratio of at least two types of pigments in primary particles of the precipitated solid solution pigment nanoparticles to the ratio of at least two types of pigments in the pigment solution mixed with the pigment precipitation solvent is within 25%.SELECTED DRAWING: Figure 5
