TRANSPARENT ELECTROMAGNETIC SHIELDING FILM AND OPTICAL FILTER USING THE SAME

摘要

Disclosed is a transparent electromagnetic shielding film having excellent electromagnetic shielding performance, high transparency and excellent durability. In addition, the color tone of this electromagnetic shielding film hardly changes in response to temperature/humidity changes. Also disclosed is an optical filter using such a transparent electromagnetic shielding film. Specifically disclosed is a transparent electromagnetic shielding film wherein a conductive pattern is formed on a supporting body by exposing and then developing a photosensitive material having a gelatin layer containing a photosensitive silver halide. This transparent electromagnetic shielding film is characterized in that the mass ratio of the thiosulfuric acid ion content in the gelatin layer relative to the silver content in the gelatin layer is not more than 1.0%.
