(57) [Problem] To provide a pigment ink for ink jet textile printing having excellent printing stability, ejection stability, storage stability, and washing fastness. SOLUTION: There is provided a pigment ink for ink-jet printing comprising at least a colorant, a water-soluble organic solvent, a blocked isocyanate and water, wherein the colorant is obtained by coating a pigment with a resin. By performing a heat treatment after the upper inkjet printing, the blocked isocyanate is cleaved and polymerized, so that the ink can achieve strong fixability. |
