Document Type and Number:

WIPO Patent Application WO/2014/129323

Kind Code:

A1

Abstract:

This ink for ink jet printing contains water, a disperse dye, a water-soluble organic solvent, and an anionic polymer dispersant. The water-soluble organic solvent is a glycerin or other polyvalent alcohol. The water-soluble organic solvent content relative to the total ink mass is 25%-50% by mass. The anionic polymer dispersant is a styrene-(meth) acrylate-based copolymer having an acid value of 160-250 mgKOH/g and a weight-average molecular weight of 8,000-20,000, and contains an acetylene glycol-based compound indicated in chemical formula (I), as a penetration agent. As a result, an ink for ink jet printing is provided that contains a disperse dye, has high quality and stable recording properties, maintains the storage stability of the ink, and is capable of increasing printing concentration on fabric surfaces. Also provided is an inkjet printing method using same.
