(57) [Abstract] [Problem] To be excellent in handling property, odor, safety, dispersion stability of colored fine particles, independent of paper, and excellent in color developing property and color tone when printing on arbitrarily selected paper. To provide a colored fine particle dispersion excellent in various properties. SOLUTION: This is a colored fine particle dispersion obtained by dispersing a colored fine particle containing an ionic group-containing polymer, an oil-soluble dye and a hydrophobic high-boiling organic solvent having a boiling point of 150 ° C. or more in an aqueous medium, wherein the colored fine particle dispersion is dispersed. The content of the hydrophobic high-boiling organic solvent in the product is 25 to 95% by mass based on the total of the ionic group-containing polymer, the oil-soluble dye, and the hydrophobic high-boiling organic solvent. This is a colored fine particle dispersion. Preferably, the colored fine particle dispersion is characterized in that the oil-soluble dye is represented by the following general formula (I).
