摘要： An object of the present invention is to provide an ink for inkjet textile printing and an inkjet textile printing method, stabilizing an emission speed and an emission direction from an inkjet recording device even when the ink contains a dye at a high concentration, capable of preventing landing deviation, and capable of drawing a straight line clearly and improving image sharpness particularly when textile printing is performed by a single pass method. The object is achieved by an ink for inkjet textile printing containing at least water, an alkylene glycol, a dye A, and a dye B, in which the dye A and the dye B are in an isomer relationship, the dye B is more hydrophobic than the dye A, and a content molar ratio between the dye A and the dye B (dye A/dye B) is from 40/60 to 80/20, and an inkjet textile printing method for performing textile printing by emitting the ink for inkjet textile printing from an inkjet head.
