摘要:
A method of processing a silver halide color photographic material comprises the steps of color-developing an image-wise exposed silver halide color photographic material and subjecting the developed material to desilvering in a processing bath having a fixing function and containing a thiosulfate compound and the following compound or analogue thereof in a molar ratio of 1/0.05 to 1/0.30. In this process, the fixing speed is extremely high even when the replenishing rate is low and the processed photosensitive material has an excellent resistance to fading by light.

Disclosed herein is a silver halide photographic light-sensitive material comprising at least one layer made of a silver halide emulsion comprising a dispersion medium and silver halide grains dispersed in the dispersion medium. Each of the silver halide grains contains a metal or metal ions other than silver. The emulsion has been chemically sensitized in the presence of a tellurium compound which has a pseudo-first order reaction rate constant k of 1.times.10.sup.-8 to 1.times.10.sup.-0 min.sup.-1. The metal is at least one polyvalent metal selected from the group consisting of Ir, Rh, Pd, Ru, Pt, Os, Fe, Ni and Co. The metal ions are ammonium salt, acetate, nitrate, sulfate, phosphate, hydroxide, or complex salt of the metal. Telluroketones or phosphinetellurides is used as the tellurium compound. It is desirable that the silver halide emulsion is a monodispersed emulsion having a variation coefficient of 22% or less. The silver halide photographic light-sensitive material has its photographic properties, particularly the gradation and the reciprocity, improved, with no reduction of its sensitivity.
