Abstract (en)

A method for storing an infrared-sensitive silver halide photographic material, comprising storing in a deoxidized state the infrared-sensitive silver halide photographic material comprising a support having thereon at least one silver halide light-sensitive emulsion layer spectrally sensitized with at least one sensitizing dye selected from a tricarbocyanine sensitizing dye, a hexamethinemerocyanine sensitizing dye, a pentamethinerhodacyanine sensitizing dye, and a heptamethinerhodacyanine sensitizing dye, said light-sensitive emulsion having a spectral sensitivity peak in the wavelength region of at least 720 n.m. and a photographic composite comprising an infrared-sensitive silver halide photographic material enclosed in a packaging material in a deoxidized state. The desensitization upon storage of the infrared-sensitive silver halide photographic material is remarkably improved.
