A silver paste ink composition comprises a plurality of first particles comprising silver; a polymer binder; a carrier solvent; and a plurality of second particles comprising silver. The second particles are nanoparticles that are different than the first silver particles, the amount of second particles in the ink composition is sufficient to impart a first color to the uncured ink composition, the first color is different than the color of the same ink composition without the nanoparticles. The silver nanoparticles have a property of causing a change in the color of the ink composition when the ink composition is cured. |
