Particularly, in recent years, the need for simple and rapid processing has increased. For example, in silver halide color printing paper, the time for immersion in a color developing solution is 1 minute or less, and the time for development including drying is 4 minutes or less.

In the present invention, the cyan coupler of the general formula (I) is usually used in an amount of from 0.002 to 2.0 per mol of the photosensitive silver halide.
It is used in moles, preferably 0.01 to 1.0 moles.
The coating amount per square meter is 0.01 to 5 mmol, preferably 0.1 to 2 mmol.

Some of the compounds of the general formula (I) are described in JP-A-59-1056.
No. 44 is known. According to the specification, the use of this coupler improves the hue and color image fastness of the cyan dye, makes it difficult for the dye to undergo reductive fading in a bleach-fix bath, and makes it possible to remove benzyl alcohol. It is disclosed. However, there was no mention of the problem of color development and color mixing during rapid processing.
This has been solved for the first time by the combined use of the contained silver halide and the cyan coupler of the general formula (I).

In the light-sensitive material of the present invention, the cyan coupler represented by the general formula (I) may be used alone or in combination of two or more. However, in this case, the proportion of the cyan coupler represented by the general formula (I) in all the cyan couplers is preferably 50 mol% or more, and 75 mol% or more.
It is more preferable if it is above. The cyan coupler represented by formula (I) may be added to either the emulsion layer or the intermediate layer, but is most preferably added to the red-sensitive emulsion layer.

The color photographic light-sensitive material of the present invention can be constituted by coating at least one blue-sensitive silver halide emulsion layer, one green-sensitive silver halide emulsion layer and one red-sensitive silver halide emulsion layer on a support. In general, color printing paper is usually coated on a support in the order described above, but may be in a different order. Further, an infrared-sensitive silver halide emulsion layer can be used in place of at least one of the above-mentioned emulsion layers. In these light-sensitive emulsion layers, a silver halide emulsion having a sensitivity in each wavelength region and a dye having a complementary color with the light to be exposed, that is, yellow for blue, magenta for green, and cyan for red are formed. By incorporating a so-called color coupler, the color reproduction by the subtractive color method can be performed. However, the photosensitive layer and the color hue of the coupler may not have the above correspondence.

As the silver halide emulsion used in the present invention, an emulsion composed of silver chlorobromide or silver chloride containing substantially no silver iodide can be preferably used. Here, "contains substantially no silver iodide" means that the silver iodide content is 1 mol% or less, preferably 0.2 mol% or less. The halogen composition of the emulsion may be different or the same between grains. However, when an emulsion having the same halogen composition between grains is used, it is easy to make the properties of each grain uniform. Regarding the halogen composition distribution inside the silver halide emulsion grains, grains having a so-called uniform structure having the same composition in any part of the silver halide grains, a core inside the silver halide grains and a shell surrounding the core are used. (Shell) [single or multiple layers] and a so-called stacked structure particle having a different halogen composition, or
Particles having a structure having a different halogen composition in a non-layered manner inside or on the surface of the particle (in the case of being on the surface of the particle, a structure in which different composition portions are bonded on the edge, corner or surface of the particle) are appropriately selected and used. be able to. In order to obtain high sensitivity, it is advantageous to use one of the latter two particles rather than particles having a uniform structure, and this is also preferable from the viewpoint of pressure resistance. In the case where the silver halide grains have the above-described structure, even if the boundary between different portions in the halogen composition is a clear boundary, it is an unclear boundary by forming a mixed crystal due to a composition difference. It is also possible to employ a structure in which a continuous structural change is positively provided.

Regarding the halogen composition of these silver chlorobromide emulsions, the silver chloride content is usually 90 mol% or more, and preferably 95 mol% or more. If the amount of silver chloride is less than 90 mol%, the color development during rapid processing becomes extremely low, and the color mixture becomes remarkable.

Such a high silver chloride emulsion preferably has a structure having a silver bromide local layer in a layered or non-layered form inside and / or on the surface of silver halide grains as described above.
The halogen composition of the localized phase is preferably at least 10 mol% in terms of silver bromide content, and more preferably more than 20 mol%. These localized layers can be inside the grains, at the edges, corners or planes of the grain surfaces. One preferred example is a layer grown epitaxially at the corners of the grains.

On the other hand, in order to minimize the decrease in sensitivity when the photosensitive material is subjected to pressure, even in a high silver chloride emulsion having a silver chloride content of 90 mol% or more, grains having a uniform distribution of the halogen composition in the grains are used. It is also preferably used.

It is also effective to further increase the silver chloride content of the silver halide emulsion in order to reduce the replenishment amount of the developing solution. In such a case, the silver chloride content is 98 mol% to 10 mol%.
Emulsions of substantially pure silver chloride, such as 0 mol%, are also preferably used.

The average grain size of the silver halide grains contained in the silver halide emulsion used in the present invention (the grain size is defined by the diameter of a circle equivalent to the projected area of the grain, and the number average thereof) is 0.1 μm to 2 μm. preferable.

The particle size distribution is preferably a so-called monodisperse coefficient of variation (a standard deviation of the particle size divided by the average particle size) of 20% or less, and preferably 15% or less. At this time, for the purpose of obtaining a wide latitude, it is also preferable to use the above monodispersed emulsion by blending it in the same layer, or to perform multi-layer coating.

The silver halide grains contained in photographic emulsions have a regular (regular, cubic, tetradecahedral or octahedral) shape.
r) Those having a crystal form, those having an irregular crystal form such as a sphere or a plate, or those having a complex form thereof can be used. Also,
It may be composed of a mixture having various crystal forms. In the present invention, among these, the particles having the above-mentioned regular crystal form should be contained in 50% or more, preferably 70% or more, and more preferably 90% or more.

In addition, emulsions in which tabular grains having an average aspect ratio (diameter / circle diameter in circle) of 5 or more, preferably 8 or more, as projected area exceeds 50% of all grains can be preferably used.

May be used. A method of forming particles in an atmosphere containing excess silver ions (a so-called reverse mixing method) can also be used. As one type of the double jet method, a method of maintaining a constant pAg in a liquid phase in which silver halide is formed, that is, a so-called controlled double jet method can be used.
According to this method, a silver halide emulsion having a regular crystal form and a nearly uniform grain size can be obtained.

In the silver halide emulsion used in the present invention, various polyvalent metal ion impurities can be introduced during the process of forming emulsion grains or physical ripening.

After desilvering such as fixing or bleach-fixing, washing and / or stabilization are generally performed.

The amount of rinsing water in the rinsing process can vary widely depending on the characteristics of the photosensitive material (for example, the material used such as a coupler), the application, the rinsing water temperature, the number of rinsing tanks (number of stages), the replenishment method such as countercurrent, forward flow, and other various conditions. Can be set. Among them, the relationship between the number of washing tanks and water volume in the multi-stage countercurrent method is described in Journal of the Society of Motion Picture and Television Engineers (Journa
l of the Society of Motion Picture and Television
Engineers), Vol. 64, pp. 248-253 (May, 1955). Usually, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 4.

According to the multi-stage countercurrent method, the amount of washing water can be greatly reduced,
For example, 0.5 l to 1 per m ^{2 of the} photosensitive material is possible, and the effect of the present invention is remarkable. However, due to the increase in the residence time of water in the tank, bacteria are propagated, and the generated suspended matter is generated on the photosensitive material. Problems such as adhesion occur. As a solution to such a problem, the method of reducing calcium and magnesium described in JP-A-62-288838 can be used very effectively. Further, isothiazolone compounds and thiabendazoles described in JP-A-57-8542, 61-12

Further, in the washing water, a surfactant as a draining agent and a chelating agent represented by EDTA as a hardening agent can be used.

It is possible to carry out the treatment with the stabilizing solution directly after the washing step or without the washing step. A compound having an image stabilizing function is added to the stabilizing solution, for example, an aldehyde compound represented by formalin, or a film suitable for stabilizing a dye.
Examples include a buffer for adjusting the pH, and an ammonium compound. Further, in order to prevent the growth of bacteria in the liquid and impart fungicidal properties to the processed photosensitive material, the above-mentioned various bactericides and fungicides can be used.

Further, a surfactant, a fluorescent whitening agent and a hardening agent may be added. In the processing of the light-sensitive material of the present invention, when stabilization is directly performed without going through a washing step, a method disclosed in
Known methods described in JP-A Nos. 8543, 58-14834, 60-220345, etc. can all be used.

In addition, it is also a preferred embodiment to use a chelating agent such as 1-hydroxyethylidene-1,1-diphosphonic acid, ethylenediaminetetramethylenephosphonic acid, or a magnesium or bismuth compound.

A so-called rinsing liquid is also used as a washing liquid or a stabilizing liquid used after the desilvering treatment.

The preferred pH of the washing step or the stabilization step is 4 to 10, more preferably 5 to 8. The temperature can be set variously depending on the use and characteristics of the photosensitive material, but is generally 15 to 45 ° C, preferably 20 to 40 ° C. The time can be set arbitrarily, but a shorter time is desirable from the viewpoint of reducing the processing time. Preferably
15 seconds to 1 minute and 45 seconds, more preferably 30 seconds to 1 minute and 30 seconds.
It is preferable that the replenishing amount is small in view of running cost, reduction of discharge amount, handleability, and the like.

A specific preferable replenishing amount is 0.5 to 50 times, preferably 3 to 4 times the amount of light-sensitive material and the amount brought in from the previous bath per unit area.
It is 0 times. Alternatively, the amount is 1 or less, preferably 500 ml or less per 1 m ^{2 of the} photosensitive material. Replenishment may be performed continuously or intermittently.

The liquid used in the water washing and / or stabilizing step can be further used in the previous step. As an example of this, the overflow of the washing water is reduced by a multi-stage countercurrent method, and is allowed to flow into a bleach-fix bath preceding the bath, and the bleach-fix bath is replenished with a concentrated solution to reduce the amount of waste liquid.

Next, the results of the present invention will be specifically described with reference to examples.
