Abstract
A producing method for a translucent electromagnetic shield film comprising exposing a photosensitive material having an emulsion layer containing a silver salt and a dye on a substrate, then executing a development process to form a metallic silver portion and a light transmitting portion respectively in an exposed area and an unexposed area, and applying a physical development and/or a plating process to the metallic silver portion thereby causing the metallic silver portion to carry a conductive metal. The producing method allows to inexpensively mass produce a translucent electromagnetic shield film without a moiré pattern, having a high EMI shield property and a high transparency at the same time.
Claims9
A conductive silver material containing a conductive metallic silver image having a volume resistivity of 1.6 to 100 μΩcm, wherein the conductive metallic silver image is produced by:
- coating a photosensitive silver halide emulsion including at least a silver halide on a substrate to form a silver salt containing layer, and
- subjecting the silver salt containing layer to exposure and chemical development.
