Abstract: A thermal inkjet dye sublimation ink consists of a disperse dye colorant dispersion, a co-solvent system, an additive, and a balance of water. The colorant dispersion is present in an amount ranging from about 1 wt % actives to about 7 wt % actives. The co-solvent system is present in a total amount ranging from about 12 wt % to about 25 wt %. The co-solvent system consists of glycerol present in an amount ranging from about 9 wt % to about 16 wt %, ethoxylated glycerol present in an amount ranging from 0 wt % to about 5 wt %, and a water soluble or water miscible organic solvent present in an amount ranging from 0 wt % to about 7 wt %. The additive is selected from the group consisting of a surfactant, a chelating agent, a buffer, a biocide, and combinations thereof.

Abstract: 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.

Abstract: A thermal inkjet dye sublimation ink consists of a disperse dye colorant dispersion, primary and secondary solvents, a chelating agent, oleth-3-phosphate, additive(s), and water. The colorant dispersion is present in an amount ranging from about 1 wt % actives to about 7 wt % actives. The amount of the primary solvent (glycerol, ethoxylated glycerol, 2-methyl-1,3-propanediol, dipropylene glycol, or combinations thereof) ranges from about 10 wt % to about 22 wt %, and the amount of the secondary solvent ranges from 0 wt % to about 7 wt %. The chelating agent amount ranges from 0 wt % actives to less than 0.1 wt % actives, and the oleth-3-phosphate amount ranges from about 0.1 wt % to about 0.75 wt. The additive is selected from the group consisting of a buffer, a biocide, another surfactant, and combinations thereof.
