    摘要： A non-white textile printing ink jet ink composition according to the present disclosure contains a pigment, a resin particle, an acetylene-based surfactant having an HLB value of 6 or more and 10 or less, and water, wherein a content of the acetylene-based surfactant is 0.5% by mass or more and 2.0% by mass or less relative to a total amount of the ink composition, and the ink composition is used for a fabric having water absorbency evaluated using a method described below is 1 or more,



    method:
    a test fabric cut into 2 cm square is mounted on a water surface in a glass bottle which has a volume of 50 mL and in which 30 mL of pure water is introduced so that a height from a bottom to the water surface is 4 cm, a fabric surface being set to be parallel to the water surface, and a time elapsed from the fabric being mounted until a portion of the fabric reaching the bottom of the glass bottle is denoted as water absorbency in seconds.
