SOLID SOLUTION PIGMENT NANOPARTICLES AND METHOD FOR PRODUCING SOLID SOLUTION PIGMENT NANOPARTICLES HAVING CONTROLLED SOLID SOLUTION RATIO

摘要

It is another object of the present invention to provide a method for producing solid solution pigment nanoparticles which are homogeneous employment ratios, solid solution pigment nanoparticles which are homogeneous employment ratios in each primary particle, and a method for controlling the employment ratio of solid solution pigment nanoparticles. At least one kind of pigment solution in which at least two kinds of pigments are dissolved in a solvent or at least two kinds of pigment solutions in which at least one type of pigment is dissolved in a solvent and a pigment precipitation solvent are mixed to precipitate at least two kinds of pigments Solid solution pigment nanoparticles, wherein the ratio of at least two kinds of pigments in the pigment solution mixed with the solvent for precipitating a pigment is such that at least two kinds of pigments in the primary particles of the solid solution pigment nanoparticles precipitated Wherein the ratio is within 25% in precision. The present invention also provides a method for producing solid solution pigment nanoparticles, solid solution pigment nanoparticles, and control method of employment ratio of solid solution pigment nanoparticles.;
