<p>Autocatalytic plating is a form of electrode-less plating in which a metal, for example, cobalt, nickel, gold, silver or copper, is deposited onto a substrate via a chemical reduction process. Coatings derived from this process are usually more uniform and adherent than from other processes and can be applied to unusually shaped surfaces. Non-metallic surfaces can also be coated via this process following suitable sensitisation of the substrate. Autocatalytic deposition is used to coat whole surfaces and the formation of metal patterns requires additional and costly additional processing such as photolithography and etching. This invention therefore provides a method of preparing a substrate material for subsequent autocatalytic deposition of a metal coating in a pre-determined pattern.</p> |
