摘要： Ink for inkjet textile printing of the present invention contains water, a disperse dye, a water-soluble organic solvent and an anionic high-molecular dispersant. The water-soluble organic solvent is a polyhydric alcohol such as glycerin. The water-soluble organic solvent is contained in an amount of 25 to 50 mass % with respect to the total mass of the ink. The anionic high-molecular dispersant is a styrene-(meth)acrylic acid-based copolymer having an acid value of 160 to 250 mg KOH/g and a weight-average molecular weight of 8,000 to 20,000. The ink for inkjet textile printing further contains an acetylene glycol-based compound expressed by the following Chemical Formula (I) as a penetrant. With this ink for inkjet textile printing, provided is disperse dye-containing ink for inkjet textile printing that has a high-quality and stable recording performance and achieves a high print density on the surface of a fabric while maintaining an ink storage stability, and an inkjet textile printing method using the ink for inkjet textile printing.
