Abstract
A conductive metal layer is formed on a substrate having a softening point above about 200.degree. C. by depositing copper and nickel particles having a substantially continuous oxide coating thereon on the substrate, and heating and pressing the metal particles at a temperature of at least 200.degree. C. Unlike similar methods wherein oxide coated metal particles are used, no developing agent is required to render the metal layer conductive. The coated substrates are useful for a variety of uses such as EMI shielding and printed circuit boards.
