An ink composition for inkjet printing, the ink composition containing a linear diol compound which has 4 or more carbon atoms and has hydroxide groups on both ends of the molecular structure thereof, a dispersing dye and a dispersant; and a textile printing method for a hydrophobic fiber by using the ink composition for inkjet printing.

Provided herein is a water-based metallic ink composition specifically adapted for direct digital inkjet printing on non-while fabrics and textile, which affords high resolution, high gloss and high luster metallic effect (high flop index) in decorations and designs that are wash-fast and stretchable. Also provided are processes of using the metallic ink compositions with other colored ink composition in direct digital inkjet printing on textile.

Provided herein is a digital ink composition containing a minimal amount of volatile organic compounds (VOC), and a method for reducing VOC emission during digital printing of an image on a fabric.

An inkjet textile printing method includes: a step A of preparing a light-colored textile pretreated with a pretreatment solution; a step B of applying by inkjet a white ink composition containing a white pigment, a water-dispersible resin, and water, to the pretreated light-colored textile; and a step C of applying by inkjet a chromatic color ink composition containing a chromatic color pigment, a water-dispersible resin, and water, onto an ink layer formed by the application of the white ink composition, in which an application amount of the white ink composition per unit area in an application region of the white ink composition is 3.0 to 13.0 times relative to an application amount of the chromatic color ink composition per unit area in an application region of the chromatic color ink composition in terms of solid content mass ratio.
