SURFACE TREATMENT AGENT, ARTICLE SURFACE−TREATED THEREWITH AND METHOD OF NICKEL PLATING USING THE AGENT

摘要

A surface treatment agent which comprises a liquid prepared by mixing or reacting a noble metal compound with a silane coupling agent having a functional group capable of capturing a metal in the molecule thereof; and the surface treatment agent further comprising an oxidizing agent, which has improved stability. The surface treatment agent allows the reduction of the make−up frequency for a catalyst liquid for use in, for example, an electroless nickel plating on copper or a copper alloy, and is improved in stability, and further improves the wettability of a surface, in particular, of a metal.
