A WATER-BASED DYE SUBLIMATION INK JET INK FOR TEXTILE PRINTING WITH ENVIRONMENTAL PROPERTY

摘要

Provided is an aqueous transfer ink for eco-friendly ink jet printing, which emits no harmful organic chemical compounds including acetonitrile, dimethyl sulfate, dimethanol amine formaldehyde or urea during a transfer process. The aqueous transfer ink for eco-friendly ink jet printing comprises: at least one dispersion pigment; an acrylic polymer dispersant; ultrapure water; a KOH pH buffering solution; a thickener formed of a mixed ethylene glycol solution containing at least one compound selected from ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and polyethylene glycol, and ultrapure water; and a moisturizing agent formed of a mixed diol solution containing at least one selected from glycerin, butanediol, propanediol and hexanediol, and ultrapure water, NMP and 2-pyrrolidone. The aqueous transfer ink emits no harmful chemicals during a transfer process performed at 180-200 deg.C.
