Abstract
A process for treating a polymeric plastic substrate to render it receptive to electroless plating including the steps of etching the substate, rinsing and activating the etched substrate with an acidic tin-palladium complex, rinsing and thereafter accelerating the activated substrate employing an improved aqueous accelerating solution containing an aqueous soluble compatible substituted alkyl amine. The improved accelerating solution is stable, easy to control, tolerant to metallic impurities present in the solution, inhibits rack plating and is of versatile use.
