Abstract
A method for ink-jet textile printing including the steps of: (a) ejecting a pigment ink from a recording head onto a fabric, wherein the pigment ink contains at least water, a pigment and a polymer, wherein the polymer has a plurality of said chains in a hydrophilic main chain and is capable of cross-linking between the side chains by irradiation of active energy rays, and (b) forming an image by irradiation of active energy rays onto the ink ejected areas.

A method for ink-jet textile printing comprising the steps of:
- (a) ejecting a pigment ink from a recording head onto a fabric, wherein the pigment ink contains at least water, a pigment and a polymer, wherein the polymer has a plurality of side chains in a hydrophilic main chain and is capable of cross-linking between the side chains by irradiation of active energy rays, the hydrophilic main chain of the polymer being a saponified polyvinyl acetate which exhibits a polymerization degree of not less than 200 and not more than 2,000, wherein the polymer contains a unit of formula (5), and
- (b) forming an image by irradiation of active energy rays onto the ink ejected areas
- in the formula, R2 is methyl group or hydrogen, n is 1 or 2, X is —(CH2)m—COO—, —CH2—COO—, or —O—, Y is an aromatic ring or a single bond, and m is an integer of 0-6.
