Pretreating agent for metal plating, and method for metal plating using the same.

摘要

A method for an electroless metal plating which can be easily applied to a powder or mirror substrate, and a pretreating agent for use in the method. The pretreating agent comprises a silane coupling agent obtained by the reaction of an azole type compound having an active functional group capable of forming a complex with a noble metal with an epoxysilane compound. A substrate to be metal-plated is subjected to a surface preparation using the pretreating agent, is then treated with a solution containing a noble metal ion, and thereafter is subjected to an electroless plating, to thereby provide a metal-plated product.
