ABSTRACT:
An adherent bright metallic coating which may be any metal or alloy capable of being deposited electrolessly, is applied to the surface of a plastic or other dielectric part (or to a metal part) by an electroless process comprising suitable pretreatment of said surface, deposition of a primary electroless copper to produce an underlayer, then depositing a bright secondary electroless coating of the desired metal (the overlayer) with complete elimination of any subsequent electroplating process [usually required to achieve this brightness]. The required overlayer may also be limited to selected surface areas of a coated part by mechanically removing portions of the primary electroless copper prior to immersion of the part in the secondary electroless bath to produce the desired overlayer metal.
