Abstract: 
The invention is to printed resistors and processes for forming same. The resistors comprise a conductive phase, preferably comprising conductive nanoparticles, and a resistive phase. In the processes of the invention, a resistor may be formed from a single ink or a plurality of inks. In the single ink embodiment, an ink is deposited which comprises a conductive phase precursor, a resistive phase precursor and a vehicle. The vehicle in removed and the conductive and resistive phase precursors are converted to a conductive phase and a resistive phase, respectively. In the multiple ink embodiment, a first ink comprising the conductive phase precursor and a first vehicle and a second ink comprising the resistive phase precursor and a second vehicle are deposited on the substrate. The vehicles are removed and the conductive and resistive phase precursors are converted to a conductive phase and a resistive phase, respectively.
