Abstract (en)
[origin: EP0044878A1] A stable colloidal solution useful for activating non-conductive substrates for subsequent alectroless plating containing colloidal copper and/or copper oxide particles as the effective activating agent, said particles having a zeta potential between about +3 and +13 millivolts a particle size between about 10 and 100 millimicrons and being stable and capable of activating a non-conductive substrate over practically the entire pH range and advantageously between a pH of about 2 through 8. Also a method of activating a non-conductive substrate using the stable colloidal solution is disclosed.
