Abstract

A novel method for processing a silver halide color photographic material. The process comprises imagewise exposing a silver halide color photographic light-sensitive material to light, color-developing the light-sensitive material, and then desilvering the light-sensitive material, wherein: (a) said silver halide color photographic light-sensitive material contains a compound which reacts with an oxidation product of anaromatic primary amine color developing agent to form a bleaching accelerator, (b) the desilvering step is conducted with a processing solution containing a ferric complex salt of an organic acid, and (c) the total amount of replenisher of the processing solution to be used in the desilvering step satisfies either the following conditions (i) or (ii): (i) the total amount of replenisher is 1,000 ml or less per m 2 of the light-sensitive material if the coated amount of silver per m 2 of the light-sensitive material is 2.0 g or more; (ii) the total amount of replenisher is 400 ml or less per m 2 of the light-sensitive material if the coated amount of silver per m 2 of the light-sensitive material is less than 2.0 g.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method for processing a silver halide color photographic material comprising a silver bromoiodide emulsion layer having a silver iodide content of 40 mol % or less, which method comprises imagewise exposing a silver halide color-photographic light-sensitive material to light, color developing the light-sensitive material, and then desilvering the light-sensitive material, wherein: (a) said silver halide color photographic light-sensitive material contains a compound which reacts with an oxidation product of an aromatic primary amine color developing agent to form a bleaching accelerator,   (b) said desilvering step is conducted with a processing solution containing a ferric complex salt of an organic acid, and   (c) the total amount of replenisher of the processing solution to be used in said desilvering step satisfies either the following conditions (i) or (ii); (i) the total amount of replenisher if from 100 to 1,000 ml per m 2  of said light-sensitive material if the coated amount of silver per m 2  of said light-sensitive material is from 2.0 g to 20 g;   (ii) the total amount of replenisher is from 50 to 300 ml per m 2  of said light-sensitive material if the coated amount of silver per m 2  of said light-sensitive material is from 0.3 to less then 2.0 g.     
     
     
       2. A method as claimed in claim 1, wherein the total amount of replenisher of the processing solution to be used in said desilvering step satisfies either the following conditions (i) or (ii): (i) the total amount of replenisher is 100 to 700 ml per m 2  of said light-sensitive material if the coated amount of silver per m 2  of said light-sensitive material is 2.0 g or more;   (ii) the total amount of replenisher is from 50 to 300 ml per m 2  of said light-sensitive material if the coated amount of silver per m 2  of said light-sensitive material is less than 2.0 g. l   
     
     
       3. A method as claim in claim 1, wherein said desilvering step is conducted with a processing solution having a bleaching capability or a subsequent processing solution having a blixing capability.
