Summary: | An example thermal inkjet dye sublimation ink consists of a disperse dye colorant dispersion, glycerol, 1,2-hexanediol, optionally a water soluble or water miscible organic solvent, optionally an additive, and a balance of water. The disperse dye colorant dispersion is present in an amount ranging from about 1 wt % actives to about 7 wt % actives based on a total weight of the ink. Glycerol is present in an amount ranging from about 5 wt % to about 30 wt % based on the total weight of the ink. 1,2-hexanediol is present in an amount ranging from about 2 wt % to about 25 wt %, and the optional water soluble or water miscible organic solvent present in an amount up to about 7 wt %, each based on the total weight of the ink. The optional additive is selected from the group consisting of a surfactant, a chelating agent, a buffer, a biocide, and combinations thereof. |
