Abstract
A conductive metal layer is formed on a substrate by depositing copper or nickel particles on the substrate, contacting the metal particles with a specified developing agent, and heating the metal particles and the developing agent. The coated substrates have conductive surfaces and are useful for a variety of uses such as EMI shielding and printed circuit boards.
