Beschreibung
Zusammenfassung:	The present invention concerns an electroless nickel plating bath suitable for application in plating on plastic processes. The plating bath is free of hazardous substances such as lead ions and ammonia and allows deposition of nickel phosphorous alloys on plastic substrates at plating temperatures not higher than 55° C. Furthermore, the deposition of copper from an immersion type copper plating bath onto the nickel phosphorous coatings require no activation step which results in less process steps and less waste water production.
