Abstract: A thermal inkjet ink composition includes cellulose nanocrystals (CNCs). The cellulose nanocrystals are present in the thermal inkjet ink composition in an amount ranging from 0.5 wt % up to 3.5 wt %, based on a total weight of the thermal inkjet ink composition. The thermal inkjet ink composition further includes a sugar alcohol present in an amount ranging from 3 wt % up to about 8 wt % based on the total weight of the thermal inkjet ink composition, an organic salt present in an amount ranging from about 0.05 wt % to about 0.5 wt % based on the total weight of the thermal inkjet ink composition, a pigment, a polar solvent, and a balance of water.

Abstract: An inkjet ink composition includes cellulose nanocrystals and a metal oxide. The cellulose nanocrystals are present in the inkjet ink composition in an amount ranging from 0.5 wt % up to 2 wt %, based on a total weight of the inkjet ink composition, and the metal oxide is present in the inkjet ink composition in an amount ranging from 0.5 wt % up to 7 wt %, based on the total weight of the inkjet ink composition. The inkjet ink composition further includes a pigment, a polar solvent and a balance of water.
