PROCESS FOR PRODUCING METAL-FILM-COATED SUBSTRATE, METAL-FILM-COATED SUBSTRATE, PROCESS FOR PRODUCING METALLIC-PATTERN MATERIAL, AND METALLIC-PATTERN MATERIAL

摘要

A metal-film-coated substrate in which the metal film has excellent adhesion to the substrate and which has a small dependence on temperature and humidity; and a process for producing the substrate. Also provided are: a metallic-pattern material which comprises a substrate and a metallic pattern having excellent adhesion to the substrate, has a small dependence on temperature and humidity, and has excellent insulation reliability in the regions not covered by the metallic pattern; and a process for producing the material. The process for producing a metal-film-coated substrate is characterized by comprising: a step (a1) in which a polymer layer is formed on a substrate, the polymer layer being made of a polymer which has a non-dissociable functional group interacting with a plating catalyst or a precursor therefor and capable of multidentate coordination and which is directly and chemically bonded to the substrate; a step (a2) in which a plating catalyst or precursor therefor capable of multidentate coordination is imparted to the polymer layer; and a step (a4) in which the plating catalyst or precursor therefor capable of multidentate coordination is plated. It may be characterized by further including, after the step (a2), the following step (a3). Step (a3) in which a metal different from the plating catalyst or precursor therefor capable of multidentate coordination is incorporated into the polymer layer.
