Abstract
A method of fixing a developed photographic silver halide material comprising at least 2 silver halide layers sensitized to different regions of the spectrum, comprising placing the material in face-to-face contact with a fixer sheet in the presence of a processing solution and a silver halide solvent which forms a solubilized silver halide species from the undeveloped areas of the material, wherein the fixer sheet contains reducing means capable of forming metallic silver therein from the solubilized silver halide.

A method of fixing a developed photographic silver halide material comprising at least two silver halide layers sensitized to different regions of the spectrum and having one or more undeveloped areas, comprising:
- providing a fixer sheet which comprises reducing means capable of forming metallic silver in said fixer sheet from solubilized silver halide, said reducing means comprising particles of a metal more electropositive than silver dispersed in said fixer sheet, and placing said photographic material in face-to-face contact with said fixer sheet in the presence of a processing solution and a silver halide solvent capable of forming a solubilized silver halide species from the undeveloped areas of the material, whereby metallic silver is formed in said fixer sheet.
