Patent ID: 10844233

Abstract:
A non-Newtonian photo-curable ink composition that comprises from about 0.1 wt % to about 10 wt % of metal oxide particles having an average particle size ranging from 1 to 50 nm; from about 0.05 wt % to about 10 Wt % of an inorganic salt; an organic solvent; a photo-initiator; and a polymerizable material; wherein the ink composition has a first dynamic viscosity ranging from 25 cps to 10,000 cps at a first state and a second dynamic viscosity ranging from 1 cps to 50 cps at a second state. Also described herein is a method for making such non-Newtonian photo-curable ink composition and a method for producing printed images using such non-Newtonian photo-curable ink composition.
