Claim:
1. An ink composition comprising: a plurality of conductive nanowires, wherein the conductive nanowires are metal nanowires; a binding material, wherein the binding material is a crosslinkable polymer; a photosensitive compound selected from the group consisting of a mixture of oxy-phenyl-acetic acid 2-[2-oxo-2-phenyl-acetoxy-ethoxy]-ethyl ester and oxy-phenyl-acetic acid 2-[2-hydroxy-ethoxy]-ethyl ester, or an onium salt that is thermally degradable and is capable of causing structural damage to the metal nanowires when heated; and a polar solvent, wherein the metal nanowires are about 0.01-10% by weight of the ink composition, and wherein the ink composition is capable of forming a transparent conductive film comprising the metal nanowires and the photosensitive compound, both of which being dispersed in the binding material, and wherein the polar solvent has a polarity index of at least 4.
