Patent ID: 10273374

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.
