ABSTRACT:
A process and catalyst for electroless plating of metal over a substrate. The process involves providing a catalyst that is the product of reaction of a noble metal with bromide ions where the ratio of bromide ions to noble metal ions is at least 100 to 1 and the noble metal is present in a concentration sufficient to catalyze an electroless plating reaction, contacting a substrate to be plated with the catalyst, and reducing the catalyst prior to or during plating of the substrate.
