ABSTRACT A direct metallization process is disclosed wherein plastic substrates may be electrolytically plated without the need for any prior electroless plating. The process uses a specially formulated post-activator composition at an elevated temperature to treat the activated substrate comprising either an alkaline solution containing an effective amount of metal ions which undergo a disproportionation reaction or an alkaline solution containing a metal ion such as Cu+2.
