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.
