Coloring composition, ink-jet ink and ink jet recording method

A coloring composition formed by dispersing coloring particulates in a water-based medium, the coloring particulates containing a nonionic oil-soluble polymer, a hydrophobic high boiling point organic solvent having a boiling point of 150° C. or more, and an oil-soluble dye, wherein the oil-soluble dye is represented by the following general formula (I):

• wherein, X represents the residue of a color coupler;
• A represents —NR4R5 or a hydroxyl group;
• R4 and R5 represent respectively independently a hydrogen atom, an aliphatic group, an aromatic group, or a heterocyclic group;
• B1 represents ═C(R6)— or ═N—;
• B2 represents —C(R7)═ or —N═;
• R2, R3, R6, and R7 represent respectively independently a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group, a heterocyclic group, a cyano group, —SR51, —SR52, —CO2R53, —OCOR54, —NR55R56, —CONR57R58, —SO2R59, —SO2NR60R61, —NR62CONR63R64, —NR65CO2R66, —COR67, —NR68COR69, or —NR70SO2R71;
• R51, R52, R53, R54, R55, R56, R57, R58, R59, R60, R61, R62, R63, R64, R65, R66, R67, R68, R69, R70, and R71 represent respectively independently a hydrogen atom, an aliphatic group, or an aromatic group;
• and
• R2 and R3, R3 and R4, R4 and R5, R5 and R6, and R6 and R7 optionally may be connected to each other to form rings.
