Abstract
A non-Newtonian photo-curable ink composition that comprises a combination of metal oxide particles in an amount ranging from about 0.1 wt % to about 20 wt % based on the total weight of the ink; 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.
