Abstract
The problem addressed by the present invention is to provide; solid solution pigment nanoparticles having a homogeneous solid solution ratio; a method for producing solid solution pigment nanoparticles having a homogeneous solid solution ratio in each primary particle; and a method for controlling the solid solution ratio of solid solution pigment nanoparticles. The solid solution pigment nanoparticles are prepared by precipitating at least two types of pigment by mixing a pigment precipitation solvent and; at least one type of pigment solution wherein at least two types of pigment are dissolved in a solvent: or at least two types of pigment solution wherein at least one type of pigment is dissolved in a solvent. The solid solution pigment nanoparticles are wherein the solid solution ratio of the at least two types of pigment in the primary particles of the precipitated solid solution pigment nanoparticles with respect to the ratio of the at least two types of pigment in the pigment solution mixed with the pigment precipitation solvent having a precision within 25%.
