Abstract
An inkjet ink composition for textile printing comprising a white pigment, a pigment dispersant, a polyurethane-based binder, a nano-sized layered silicate and an aqueous liquid vehicle. Also described herein is a fluid set comprising said ink and a fixer composition including a cationic polymer and a fixer vehicle; as well as the textile printing method using it.
Claims18
An inkjet ink composition for textile printing, the inkjet ink composition comprising:
- a. a white pigment;
- b. a pigment dispersant;
- c. from 10 wt % to about 20 wt % of a polyurethane-based binder based on a total weight of the inkjet ink composition, the polyurethane-based binder being selected from the group consisting of a polyester-polyurethane binder, a polyether-polyurethane binder, a polycarbonate-polyurethane binder, and combinations thereof, wherein the polyurethane-based binder has a weight average molecular weight (Mw) ranging from about 300,000 to about 1,000,000;
- d. a nano-sized layered silicate;
- and
- e. an aqueous liquid vehicle.
