PROBLEM TO BE SOLVED: To provide a dispersion of colored fine particles which shows an excellent dispersion stability of colored particles, has no dependence on papers, yields an excellent color development and color tone when printed on a randomly selected paper, shows an excellent water resistance and light resistance and is suitable as an aqueous ink for writing, an aqueous printing ink, an ink for data recording, etc. SOLUTION: The dispersion of colored fine particles comprises colored fine particles containing an oil-soluble dye of formula (I) and an oil-soluble polymer. Preferably, the oil-soluble polymer is a vinyl polymer, and the dissociative groups in the vinyl polymer comprises at least a carboxyl group or a sulfonate group. |
