An ink composition including a metal nanoparticle; a viscous heat decomposable liquid, wherein the viscous heat decomposable liquid imparts a desired viscosity to the ink composition and which evaporates at a sintering temperature of the metal nanoparticle; an optional solvent; wherein the ink composition has a metal content of less than about 25 percent by weight, based upon the total weight of the ink composition; and wherein the ink composition has a viscosity of from about 50 to about 200 centipoise at a temperature of about 20 to about 30 °C. A process for preparing the ink composition and for printing the ink composition. A flexographic printing process or gravure printing process including the ink composition.
