    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: 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.

    Abstract: A printing method includes selecting a dye sublimation ink, having: a disperse dye colorant dispersion; a primary solvent selected from the group consisting of glycerol, ethoxylated glycerol, 2-methyl-1,3-propanediol, dipropylene glycol, and combinations thereof; a surfactant selected from the group consisting of nonionic surfactants, anionic surfactants, and combinations thereof; an additive selected from the group consisting of a buffer, a biocide, a chelating agent, and combinations thereof; and a balance of water. An operating energy that includes a margin over a turn-on energy (TOE) for a thermal inkjet printhead is applied to a heating resistor of the printhead, wherein the margin ranges from about 10% to about 25% over the TOE. The dye sublimation ink is printed from the thermal inkjet printhead i) directly onto a textile substrate, or ii) onto a transfer medium to form an image thereon; and the image is transferred onto the textile substrate.
