Abstract
The present disclosure provides non-Newtonian inkjet inks and related methods. In one example, a non-Newtonian inkjet ink can comprise a low molecular weight organic gelator 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 20% by weight based on the total weight of the non-Newtonian inkjet ink; and an organic solvent. Additionally, the low molecular weight organic gelator and the salt can form a structured network and the inkjet ink can have a viscosity ranging from 100 cps to 10,000 cps at a temperature of 25° C. and a viscosity ranging from 1 cps to 10 cps at a temperature of 50° C.
