Abstract: There is provided a new process for the production of printed circuits. The process comprises coating a base with a layer of copper, nickel, cobalt or iron salts or salt compositions, which on exposure to radiant energy, such as heat, light, etc., thermal or chemical reducing agents are converted to a layer of metal nuclei that is non-conductive, but which is capable of catalyzing the deposition of metal onto the base from an electroless metal deposition solution in contact with the metal nuclei.
