A method of a processing of a silver halide color photographic material is disclosed. The process comprises a step of developing the exposed color photographic material and a step of treating the developed color photographic material with a bleach-fixing solution. The bleach-fixing solution contains an organic acid ferric complex. At least one layer of the emulsion layers of the photographic material contains silver halide grains containing from 0.5 to 25 mol % of silver iodide. The total dry-thickness of the photographic component layers contained in the photographic material is from 8 to 25 .mu.m and the swelling rate T1/2 of the photographic component layers is not more than 25 sec. The method is suitable for rapid processing of the fine grain-type high-speed silver iodide-containing color photographic material. The method uses a bleach-fixing bath enabling the rapid processing of the high-speed color photographic material.

Method of processing silver halide color photographic material

A method of processing of a silver halide color photographic light-sensitive material is disclosed. The color photographic material to be processed comprises a support and photographic component layers including a blue-sensitive, green-sensitive and red-sensitive silver halide emulsion layers, and at least one of the photographic emulsion layers comprises a silver halide containing 0.5 to 25 mol % of silver iodide. The total thickness of the photographic component layers is from 8 to 25 .mu.m and the swelling rate T1/2 of this layers is not more than 25 sec. At least one of the emulsion layers contains a specific coupler. The color photographic material is processed with a bleach-fixing solution containing an organic acid ferric complex after a developing treatment. The processing by this invention provides high sensitivity and minimized cyan dye loss of the photographic material.

Rapid bleach fixing of a silver halide color photographic

Disclosed is a color forming method which comprises subjecting a light-sensitive silver halide color photographic material having a photographic constituent layer comprising blue-sensitive, green-sensitive and red-sensitive silver halide emulsion layers on a support and having a total thickness of the photographic constituent layer of 25 .mu.m or less to imagewise exposure, then carrying out color developing processing of the exposed material in the presence of a dye forming coupler and processing the developed image with a bleach-fixing solution. The color forming method of the present invention enables rapid processing of a high sensitivity color light-sensitive material.

Color image forming method comprising processing with a bleach-fixing

Disclosed is a bleach-fixing solution for light-sensitive silver halide color photographic material, comprising a diethylenetriamine pentaacetic acid iron (III) complex salt and having a pH value of 4.0 or higher. Also disclosed is a method for processing a light-sensitive silver halide color photographic material, which comprises processing a light-sensitive silver halide color photographic material containing a cyan coupler by the use of the above bleach-fixing solution.
