Abstract
A photosensitive film, which has a transparent support and a silver salt emulsion layer containing a silver salt formed thereon, is exposed and developed to form a metallic silver portion. The base material to be plated is electrified in an electrolytic solution free of plating substances, using the metallic silver portion as a cathode. Then, the electrified base material is subjected to an electroless plating treatment to form a first plated layer only on the metallic silver portion. The base material is subjected to an electroplating treatment to form a second plated layer on the first plated layer, further form a third plated layer on the second plated layer.
Claims10
A method for producing a conductive material, comprising the steps of:
- exposing and developing a photosensitive film having a support and a silver salt emulsion layer containing a silver salt formed thereon, to form a metallic silver portion;
- electrifying said photosensitive film in an electrolytic solution substantially free of plating substances by bringing a metal electrode into contact with said metallic silver portion, the metal electrode having a hydrogen overvoltage higher than a hydrogen overvoltage of the metallic silver portion, said metallic silver portion being used as a cathode;
- and
- subjecting said metallic silver portion to a plating treatment to form a conductive layer.
