Abstract
A process is described for providing a conductive metal circuit using a coherent radiation source. The circuit pattern is directly written onto a laser addressable element having a supercooling material layer. A conductive metal toner is then applied to the light struck areas and fired in a furnace to provide a conductive metal circuit.
