Thermal inkjet dye sublimation ink

A cyan thermal inkjet dye sublimation ink, consisting of:

• a cyan disperse dye colorant dispersion present in an amount ranging from about 1 wt % actives to about 7 wt % actives based on a total weight of the ink, the cyan disperse dye colorant dispersion consisting of a single cyan disperse dye, a dispersant, and a dispersion vehicle;
• glycerol present in an amount ranging from about 6 wt % to about 15 wt % based on the total weight of the ink;
• 1,2-hexanediol present in an amount ranging from about 2 wt % to about 6 wt % based on the total weight of the ink;
• optionally a water soluble or water miscible organic solvent present in an amount up to about 7 wt % based on the total weight of the ink;
• optionally an additive selected from the group consisting of a surfactant, a chelating agent, a buffer, a biocide, and combinations thereof;
• and
• a balance of water.

A printing method, comprising:

• thermal inkjet printing, from a thermal inkjet printhead, a dye sublimation ink:
• i) directly onto a textile fabric to form an image;
• or
• ii) onto a transfer medium to form an image on the transfer medium;
• and
• transferring the image from the transfer medium onto a textile substrate;
• wherein the dye sublimation ink consists of:
• a disperse dye colorant dispersion present in an amount ranging from about 1 wt % actives to about 7 wt % actives based on a total weight of the ink;
• glycerol present in an amount ranging from about 5 wt % to about 30 wt % based on the total weight of the ink;
• 1,2-hexanediol present in an amount ranging from about 2 wt % to about 25 wt % based on the total weight of the ink;
• optionally a water soluble or water miscible organic solvent present in an amount up to about 7 wt % based on the total weight of the ink;
• optionally an additive selected from the group consisting of a surfactant, a chelating agent, a buffer, a biocide, and combinations thereof;
• and
• a balance of water.
