Abstract

Procedure for preparing a silver image in the same sense as the original, in a photographic material containing at least one photosensitive emulsion, constituted by a silver halide, by exposure, first development to form a metallic silver image, conversion of the metallic silver image in an image of silver salt of easier solution than the mentioned silver halide, dissolution of the silver salt image with a solvent for silver salts and reduction of the undisclosed silver halide, whose procedure is characterized by the The material is treated, at the earliest after the first development and at the latest during the performance of the solvent for silver salts, with a passivating compound that forms an even more difficult silver dissolution compound with silver. Silver halide mentioned. (Machine-translation by Google Translate, not legally binding)
