Abstract
The present invention concerns an aqueous plating bath composition for electroless deposition of palladium and/or palladium alloys and a method which utilises such aqueous plating bath compositions. The aqueous plating bath comprises a source of palladium ions, a reducing agent, a nitrogenated complexing agent which is free of phosphorous and at least one organic stabilising agent comprising 1 to 5 phosphonate residues. The aqueous plating bath and the method are particularly useful if the aqueous plating bath comprises copper ions.
