Embodiment 1

[0342] Emulsion (preparation of B-11~14) control example: silver chloride cube, side length 0.46 microns

[0343] High silver chloride cubic particles were prepared by a conventional method of simultaneously adding and mixing silver nitrate and sodium chloride to a stirred aqueous gelatin solution. Among them, potassium bromide is added during the period of adding 80% to 90% of silver nitrate. Inside, add K 4 [Ru(CN) 6 ]. And during the period of adding 83% to 88% of silver nitrate, adding K 2 [IrCl 6 ], during the period of adding silver nitrate 90% to 95%, adding K 2 [Ir(5-methylthiazole)Cl 5 ]. After desalting the obtained emulsion, gelatin was added to redisperse it. The resulting particles are cubic emulsions with side lengths of 0.46 microns and a coefficient of variation of 9.5% surrounded by six parallel {110} faces.

[0344] Dissolve the emulsion at 40°C, add sensitizing pigment Dye-1 and sodium thiosulfonate, add sodium thiosulfate pentahydrate as a sulfur s...

Description

technical field [0001] The invention relates to a silver halide color photographic photosensitive material and a method for forming a color image. More specifically, the invention relates to a method suitable for rapid processing, high sensitivity, and the influence of temperature changes and treatment liquid changes on sensitivity during exposure. Small silver halide color photographic photosensitive material and color image forming method. Background technique [0002] As we all know, color photography is developed by using an aromatic primary amine-based color-developing main agent to develop a photosensitive material containing a pigment on a support to form a coupler (coupler) and a silver halide emulsion. The reaction of the pigment to form a coupler (hereinafter referred to as the coupler) to obtain a method of forming an image with a pigment can obtain a high-quality color photo. [0003] However, in recent years, as other color printing methods, technologies such a...
