Abstract:
1. A method for producing a light-transmitting electromagnetic wave-shielding film having a conductive metal portion and a light transmitting portion, which comprises exposing a silver salt-containing layer to an electromagnetic wave, wherein the silver salt-containing layer contains a silver salt and the silver salt-containing layer is provided on a support, developing said exposed silver salt-containing layer with a development technique used for a silver salt photographic film so as to form a metal silver portion, and subjecting the metal silver portion to physical development and/or plating to form the conductive metal portion consisting of the metal silver portion carrying conductive metal particles; wherein the silver salt-containing layer contains Ag and a binder and has an Ag/binder volume ratio of 1/1 or higher.
