ARTICLE IN WHICH A NON-CONDUCTIVE SUBSTRATE IS COATED WITH ELECTROPLATED METAL AND PROCESS FOR ITS MANUFACTURE

摘要

An article comprises a non-conductive substrate, the surface of which has been chemically modified by treatment with an acidic reactant selected from oxidants and etchants, and subsequently coated with a film of at least one water-insoluble sulfide of at least one metal selected from Periodic Groups IB, IIB, IVA and IVB, the sulfide being formed on the surface in absence of elemental noble metal and platinum group metal compounds, and being coated with at least one electroplated metal superimposed directly on the sulfide film.
