PALLADIUM COMPLEX AND CATALYST-IMPARTING TREATMENT SOLUTION USING THE SAME

摘要

The object is to provide a technique for forming a selective metal coating film on a non-conductive resin by allowing a catalyst metal to adsorb selectively onto an anionic group (e.g., a carboxyl group) on the resin. Thus, disclosed are: a palladium complex represented by the formula (I) below or a structural isomer thereof; a catalyst-imparting treatment solution for electroless plating, comprising the palladium complex or the isomer as an active ingredient; and a method for formation of a metal plating coating film on a non-conductive resin, comprising the steps of subjecting a non-conductive resin having an anionic group formed on its surface to a catalyst-imparting treatment with the catalyst-imparting treatment solution and then performing reduction treatment, electroless metal plating and electrolytic plating. (I) wherein L represents an alkylene group; and R represents an amino group or a guanidyl group.
