摘要:
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.
