Abstract: An ink composition including a metal nanoparticle; at least one aromatic hydrocarbon solvent, wherein the at least one aromatic hydrocarbon solvent is compatible with the metal nanoparticles; at least one aliphatic hydrocarbon solvent, wherein the at least one aliphatic hydrocarbon solvent is compatible with the metal nanoparticles; wherein the ink composition has a metal content of greater than about 45 percent by weight, based upon the total weight of the ink composition; wherein the ink composition has a viscosity of from about 5 to about 30 centipoise at a temperature of about 20 to about 30° C. A process for preparing the ink composition. A process for printing the ink composition comprising pneumatic aerosol printing.

Abstract: A metal nanoparticle ink dispersion is made by mixing ingredients comprising: a first solvent being nonpolar and having a boiling point above 160° C. at 1 atmosphere pressure; a second solvent having a boiling point above 230° C. at 1 atmosphere pressure, the second organic solvent being an aromatic hydrocarbon and having a higher boiling point than the first hydrocarbon solvent; and a plurality of metal nanoparticles. A method of printing the metal nanoparticle ink dispersion is also disclosed.
