An ink jet textile printing ink composition contains a sulfonic acid group-containing dye having a ligand coordinated to a metal atom, the ligand being represented by Formula (1) below:wherein at least one of R<sub>1</sub>and R<sub>3</sub>represents SO<sub>3</sub><sup>-</sup>or SO<sub>3</sub>Y, where Y represents a hydrogen atom, an alkali metal atom, or an alkaline earth metal atom; when not representing SO<sub>3</sub><sup>-</sup>or SO<sub>3</sub>Y, R<sub>1</sub>and R<sub>3</sub>represent a halogen atom or a hydrogen atom; R<sub>2</sub>and R<sub>4</sub>each independently represent a hydrogen atom, a halogen atom, a sulfo group, a nitro group, an aryl group, a sulfonamide group, a carboxy group, an alkyl group of 1 to 4 carbon atoms, SO<sub>2</sub>NHR<sub>5</sub>, or COOR<sub>5</sub>, where R<sub>5</sub>represents a hydrogen atom or an alkyl group; and X represents a metal atom. |
