摘要:
PROBLEM TO BE SOLVED: To provide color particles capable of forming a recorded image micronized and having high image density. SOLUTION: In the color particles containing a dye and a polymer compound, the average particle diameter of the color particles measured by a dynamic light scattering method is 10 to 80 nm, the content of the dye of the color particles is in the range of 60 to 90 mass%, and the dye has a solubility index of 7.50 or more in water having a pH of 6.0 to 11.0, the solubility index being represented by the following equation (1): solubility index=log(1/aqueous solubility of dye [mol/L]).
