Abstract

Abstract A metal coated structure is disclosed and includes a substrate, an actinic-sensitive coating thereon which becomes adherent upon exposure to actinic radiation and a thin metal coating over the actinic-sensitive coating which will transmit actinic radiation for rendering the actinic-sensitive coating adherent to the substrate and the metal coating. After exposure to actinic radiation, the adhered metal coating is useful per se or provides a basis for further metal coatings such as electroless and electrolytic deposited metal coatings.
