Abstract
A process for treating a polymeric plastic substrate to render it receptive to electroless plating in a process of the type including the steps of etching the substrate and activating the etched substrate. The present improvement includes the step of accelerating the activated substrate with an improved aqueous accelerating solution containing an aqueous soluble compatible oxidizing agent present in an amount effective to increase the activity of the accelerating solution. The improved accelerating solution inhibits the plating of stop-off coatings and plating racks and is of versatile use.
