Abstract
The present disclosure provides non-Newtonian inkjet inks and related methods. In one example, a non-Newtonian inkjet ink include a dispersion of metal oxide particles in an amount ranging from 0.1% to 10% by weight based on the total weight of the non-Newtonian inkjet ink; a salt in an amount of 0.05% to 10% by weight based on the total weight of the non-Newtonian inkjet ink; and an organic solvent. Additionally, the metal oxide form a structured network in a presence of the salt and the inkjet ink have a dynamic viscosity ranging from 25 cps to 10,000 cps at shear rate of 5 sand a dynamic viscosity ranging from 1 cps to 50 cps at a shear rate of 10,000 s.
