  • Publication number: 20060093732
    Abstract: Systems and methods for forming templates for trace or circuit deposition are described. Specifically, a method of forming a template for trace or circuit deposition can comprise steps of jetting an ink-jettable composition onto a substrate in a predetermined pattern, wherein the ink-jettable composition includes a liquid vehicle and at least one coupling agent dispersed therein. The substrate can include functional groups interactive with the coupling agent, wherein upon contact between the coupling agent and the substrate after the jetting step, the coupling agent becomes attached or attracted to the substrate. The method can also include the step of contacting the coupling agent with a metal-containing composition such that a metal of the metal-containing composition becomes attached or attracted to the coupling agent.
