OXIDIZING AGENT FOR ACIDIC ACCELERATOR ABSTRACT OF THE DISCLOSURE A process for treating a polymeric plastic sub- strate to render it receptive to electroless plating in a process of the type including the steps of etching the sub- strate and activating the etched substrate. The present improvement includes the step of accelerating the activated substrate with an improved aqueous accelerating solution con- taining an aqueous soluble compatible oxidizing agent present in an amount effective to increase the activity of the accelera- ting solution. The improved accelerating solution inhibits the plating of stop-off coatings and plating racks and is of versatile use.
