PRETREATMENT AGENT FOR ELECTROLESS PLATING, AND PLATING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of depositing a plating film having excellent adhesiveness to a base material by a simple means without performing etching by harmful chromic acid or the like. SOLUTION: This pretreatment agent for electroless plating contains cation exchange resin fine powder and coating film forming resin. Before the electroless plating step, pretreatment agent for plating is applied on a surface of a non-conductive base material and a coating film is formed thereon. Then, the coating film is immersed in aqueous solution containing metal ions to adsorb metal ions on the surface of the coating film of the pretreatment agent. Further, metallic nuclei are formed by the chemical reducing treatment, and the electroless plating is performed. The plating film having excellent adhesiveness can be obtained by the anchor effect to be represented by unevenness of the shape of ion exchange resin fine powder densely present on the surface of the coating film.
