(57) [Abstract] [Problem] It is not dependent on paper, has excellent color developability and color tone when printed on arbitrarily selected paper, and has easy handling, odor, safety, Provided is a coloring composition which is excellent in water resistance, light resistance, etc., enables high recording density and high image quality, and is suitable for aqueous ink for writing. SOLUTION: This is a coloring composition containing an oil-soluble dye represented by the following general formula (1). An embodiment in which an oil-soluble dye is dispersed in an aqueous medium, an oil-soluble dye dissolved in a high-boiling organic solvent having a boiling point of 150 ° C. or higher and a relative dielectric constant of 3 to 12 at 25 ° C. in an aqueous medium. Preferred are an embodiment including a dispersed dye dispersion, and an embodiment including a colored fine particle dispersion in which colored fine particles containing an oil-soluble dye and an oil-soluble polymer are dispersed in an aqueous medium. In the general formula (1), A represents an aryl group or a heterocyclic group, X represents an atom or an atomic group that can be a cation, and R represents a substituent. n represents the integer of 0-4.
