1. A method for printing on a textile, comprising:
- generating a print by thermal inkjet printing a thermal inkjet ink on a cotton fabric, the thermal inkjet ink including;
a pigment;
a single dispersant and binder resin, the single dispersant and binder resin being a styrene acrylic resin having an acid number greater than 100 mg KOH/g and a weight average molecular weight less than 50,000;
a vehicle including a co-solvent, an anti-kogation agent, an anti-decel agent, a surfactant, a biocide, a pH adjuster, or combinations thereof; and
a balance of water;
wherein the print is generated without a post-printing curing process.

Abstract
In an example of a method for printing on a textile, a print is generated by thermal inkjet printing a thermal inkjet ink on a cotton fabric. The thermal inkjet ink consists of a pigment, a single dispersant and binder resin, a vehicle, and a balance of water. The single dispersant and binder resin is a styrene acrylic resin having an acid number greater than 100 mg KOH/g and a weight average molecular weight less than 50,000. The vehicle includes a co-solvent, an anti-kogation agent, a humectant, a surfactant, a biocide, or combinations thereof. The print is generated without a post-printing curing process.
