    Abstract: An ink composition is described herein. In one example, an ink includes at least one pigment, at least one dispersant, and at least one durable polymer in a water-based dispersion medium including at least one hydrophilic solvent. The dispersant is present at from about 0.05 wt % to about 15 wt % of the ink composition. Further, the ink composition includes at least one dispersion additive.

    Abstract: The present disclosure provides a white ink including an aqueous ink vehicle, from 5 wt % to 50 wt % of a white metal oxide pigment having an average particulate size from 100 nm to 2,000 nm, from 0.1 wt % to 4 wt % of anionic oxide particulates having an average particulate size from 1 nm to 100 nm, from 2 wt % to 30 wt % of latex particulates having a glass transition temperature from 0 C. to 130 C., and a non-ionic or predominantly non-ionic dispersant having an acid number not higher than 100 mg KOH/g based on dry polymer weight. The white metal oxide pigment and anionic oxide particulates are present in the white ink at a weight ratio from 5:1 to 200:1.

    Abstract: The present disclosure is drawn to a fluid set for inkjet imaging which includes a white inkjet ink and a fixer fluid. The white ink can include an aqueous ink vehicle, from 5 wt % to 50 wt % of a white metal oxide pigment having an average particulate size from 100 nm to 2,000 nm, and from 0.1 wt % to 4 wt % of anionic oxide particulates having an average particulate size from 1 nm to 100 nm. The white ink can also include a non-ionic or predominantly non-ionic dispersant having an acid number not higher than 100 mg KOH/g based on dry polymer weight. The fixer fluid can include an aqueous fixer vehicle and from 0.1 wt % to 25 wt % cationic polymer.

    Abstract: The present disclosure is drawn to fluid sets for inkjet imaging and can comprise a white ink and a fixer fluid. The white ink can include an aqueous ink vehicle, from 5 wt % to 50 wt % of a white metal oxide pigment, and from 0.02 wt % to 2 wt % of an anionic low molecular weight polymer. The white metal oxide pigment can have an average particulate size from 100 nm to 2,000 nm, and can be dispersed by a non-ionic or predominantly non-ionic dispersant having an acid number not higher than 100 mg KOH/g based on dry polymer weight. The anionic low molecular weight polymer can have a weight average molecular weight of 3,000 Mw to 50,000 Mw and an acid number higher than 100 mg KOH/g based on dry polymer weight. The fixer fluid can include an aqueous fixer vehicle and from 0.1 wt % to 25 wt % cationic polymer.
