CONDUCTIVE-SUBSTANCE-ADSORBING RESIN FILM, PROCESS FOR PRODUCING CONDUCTIVE-SUBSTANCE-ADSORBING RESIN FILM, METAL-LAYER-COATED RESIN FILM MADE FROM THE SAME, AND PROCESS FOR PRODUCING METAL-LAYER-COATED RESIN FILM

摘要

A conductive-substance-adsorbing resin film having a surface on which a conductive layer having excellent adhesion to the resin film and small irregularities at the interface with the resin film can be easily formed; a process for producing the resin film; a metal-layer-coated resin film which is obtained from the conductive-substance-adsorbing resin film and in which a highly precise wiring having excellent adhesion to the insulating resin film can be easily formed; and a process for producing a metal-layer-coated resin film which is a material capable of giving, by a simple method, a printed wiring board having a highly precise wiring. The conductive-substance-adsorbing resin film is composed of at least two resin layers, at least one of the resin layers being an adsorbent resin layer having the property of adsorbing a conductive substance or metal. The metal-layer-coated resin film can be obtained by adsorbing a metal onto this conductive-substance-adsorbing resin layer and then plating this layer.
