1. A process for forming a conductive feature, wherein the process comprises the steps of:
- (a) applying a first ink comprising a metal precursor to at least a portion of a first substrate to form an at least partially coated substrate; and
(b) contacting the first ink with a primary reducing agent under conditions effective to reduce the metal in the metal precursor to its elemental form.

Abstract
Processes for forming conductive features from one or more inks and conductive features formed from the processes. In one aspect, the process includes a step of applying a first ink comprising a metal precursor to at least a portion of a first substrate to form an at least partially coated substrate. In a second step, the first ink is contacted with a reducing agent, optionally derived from a second ink, under conditions effective to reduce the metal in the metal precursor to its elemental form.
