Abstract
The present disclosure provides non-Newtonian inkjet inks and related methods. In one example, a non-Newtonian inkjet ink can comprise silica, alumina, and organic solvent. The non-Newtonian inkjet ink can be an aqueous ink having a pH from 9 to 12 and a conductivity from 100 to 2000 μS/cm.
Claims15
A non-Newtonian inkjet ink, comprising:
- silica in an amount ranging from 0.1% to 10% by weight based on the total weight of the non-Newtonian inkjet ink;
- alumina in an amount from 0.25% to 5% by weight based on the total weight of the non-Newtonian inkjet ink;
- and
- organic solvent in an amount from 5% to 50% by weight based on the total weight of the non-Newtonian inkjet ink,
- wherein the non-Newtonian inkjet ink is an aqueous ink having a pH from 9 to 12 and a conductivity from 100 to 2000 μS/cm.
