Description

TECHNICAL FIELD The present invention relates to a silver halide color photographic light-sensitive material containing a high content of silver chloride, and more specifically, it can be rapidly processed and has high sensitivity. The present invention relates to a silver halide color photographic light-sensitive material having a small performance variation due to a change in manufacturing lot.

BACKGROUND OF THE INVENTION Silver halide color photographic light-sensitive materials are very widely used today because of their high sensitivity and excellent gradation.

However, the development processing of a silver halide color photographic light-sensitive material is a so-called wet processing, and it takes time to prepare a processing solution, it becomes dirty, a waste solution containing various chemicals is produced, a dark room is required, and after the operation is started. There are various drawbacks such as a long time until the first print is obtained. In order to make up for these drawbacks and make full use of the advantages of the silver halide color photographic light-sensitive material described above, until now, a skilled engineer has concentrated on the development of color negatives to the production of color prints at a few large development laboratories. Has been adopted.

However, although the essence of wet processing has not changed in recent years, improvements in equipment such as printers and automatic processors, improvements in developing solutions, improvements in silver halide color photographic light-sensitive materials and their packaging forms have been accumulated, and department stores The so-called minilab, which consistently processes from the development of color negatives to the production of color prints in a small space in stores, is rapidly becoming popular.

Under these circumstances, it has been desired that color prints of even better quality can be produced more easily and in a shorter time.

In order to achieve rapid processing of silver halide color photographic light-sensitive materials, it is necessary to shorten each of the basic steps of color photography, color development, bleaching, fixing, washing and drying. In particular, the color developing step is long in time and the effect of improvement is great.

In order to shorten the processing time in the color development step, there is a method of increasing the silver chloride content of silver halide grains contained in the light-sensitive material. However, in this method, the sensitivity of the blue-sensitive emulsion layer is lowered, and as a result, in the yellow high density region,
Magenta turbidity occurs due to long-wavelength blue light. Further, there is a drawback that the fog is significantly increased even by a bleach-fixing solution which is mixed in a very small amount in the color development processing solution.

As a method for improving the low sensitivity, by using the compound of the general formula [I], the high chloride silver halide emulsion can be
In particular, the efficiency of color sensitization is high and preferable spectral sensitivity can be provided.

In JP-A-55-135,832, a silver halide emulsion consisting of 80 mol% or more of silver chloride, 5 mol% or more of silver iodide and the rest of silver bromide is doped with cadmium, copper, lead and zinc. It is disclosed that a highly sensitive emulsion can be obtained by sensitizing the surface of the emulsion. By chemically ripening the silver halide emulsion doped with this metal ion and containing the compound of the general formula [I], it has preferable spectral sensitivity and extremely high sensitivity as compared with the case where each technology is used alone. A silver halide emulsion of is obtained.

However, it has been found that the sensitivity is increased and the tone becomes softer if it is set and stored after the chemical ripening and before the production of the light-sensitive material. This means that if the period from the chemical ripening of the silver halide emulsion to the production of the light-sensitive material is different, the sensitivity and gradation of the light-sensitive material produced will be different and the performance variation for each production lot will be large. If the performance variation for each production lot becomes large, it will be necessary to reset the conditions at the time of lot switching, and it will take a lot of time, which is not preferable.

In addition, as one method for shortening the processing time in the color developing step, a development accelerator is used when the exposed silver halide color photographic light-sensitive material is developed using an aromatic primary amine type color developing agent. Is known to be used.
For example, a development accelerator containing a quaternary nitrogen atom, a polyethylene oxide type development accelerator, an imidazole type development accelerator, a polyacrylamide polyacrylic acid development accelerator, and a development accelerator having a thione group are known.

However, among such development accelerators, compounds having a relatively high activity often have the drawback of forming fog.

Further, it is known that 1-arylpyrazolidones such as 1-aryl-3-pyrazolidone are added to a silver halide color photographic light-sensitive material and processed within an extremely short developing time.

However, each of these techniques is not always satisfactory in terms of obtaining a dye image having a sufficient color developing rate and a high color density, and there is still room for improvement.

Further, in JP-A-58-50533, 1-aryl-3-
Although a method of promoting development by the combined use of pyrazolidone and a non-photosensitive silver halide grain is disclosed, a sufficient development promoting effect is not obtained even in this method.

Under such circumstances, the present inventors have focused their attention on the silver halide emulsion containing high temperature silver halide, and as a result of continuing the research, as a result, the sensitivity decrease when a high silver chloride containing emulsion is used as a color photographic emulsion. Could be improved by sensitizing with the compound represented by the general formula [I] and by doping with metal ions. However, the performance fluctuation as described above (for example, performance fluctuation for each production lot). Was rather large and forced to reset the conditions due to fluctuations, which resulted in the drawback of being against time reduction, and still this drawback could not be ameliorated.

As a result of further research on this point, a silver halide emulsion having a high silver chloride content was doped with a metal ion and sensitized with a compound represented by the general formula [I]. By adding the compound shown, it has become possible to produce a silver halide color emulsion having high sensitivity, desensitization, and small performance variation between production lots.

[Object of the Invention] An object of the present invention is to provide a silver halide color photographic material capable of rapid development, capable of obtaining an image of high sensitivity and stable quality, and having small performance fluctuation.

 The present invention will be described more specifically.

In the silver halide emulsion used in the present invention, 80 mol% or more of the total silver halide is silver chloride, and the balance is silver bromide and / or silver iodide. Preferably, it contains silver chloride in an amount of 95 mol% or more of the total silver halide.

An emulsion containing only 80 mol% or less of silver chloride is not suitable for rapid processing, and the effect of the present invention cannot be sufficiently exhibited.

The content of the remaining silver bromide and silver iodide is preferably substantially free of silver iodide, but may be 0.5 mol% or less, preferably 0.2 mol% or less.

The distribution state of silver halide other than silver chloride in the grains is not particularly limited. For example, it may be localized in the central portion of the particle, a portion between the particle and the surface, or may be distributed on the average. It is preferable that the particles are distributed on average. The average grain size of the silver halide grains used in the present invention is preferably 1 μm or less. The average particle size is expressed as follows. In the case of cubic silver halide grains, the grain size of silver halide grains is the length of one side, and in the case of grains other than cubes such as spheres, when converted to cubes having the same volume. The particle diameter is defined by the length of one side, and the average particle diameter is ri which is the particle diameter of each particle and ni is the number of particles having the particle diameter ri. Expressed as

The particle size distribution of the silver halide particles used in the present invention,
It may be polydisperse or monodisperse, but a monodisperse emulsion is more preferable. Here, monodisperse refers to the particle size distribution of silver halide grains contained in the emulsion,
An emulsion having a coefficient of variation of 22% or less, preferably 15% or less.

The coefficient of variation is a coefficient indicating the breadth of the particle size distribution and is defined by the following equation.

The above particle size can be measured by various methods generally used in the art for the above purpose. A representative method is Loveland's "Particle Size Analysis" ASTM Symposium on.
Wright Microscopy, 1955, pp. 94-122, or "Theory of Photographic Processing," co-authored by Mies and James,
It is described in Chapter 2 of the third edition, published by Macmillan Company (1966).

The silver halide grains used in the silver halide emulsion of the present invention may be obtained by any of an acidic method, a neutral method and an ammonia method. The grains may be grown at one time, or may be grown after the seed grains are made. The method of forming seed particles and the method of growing seed particles may be the same or different.

In the silver halide emulsion, halide ions and silver ions may be mixed at the same time, or the other may be mixed in a liquid containing either one. Alternatively, it may be formed by sequentially and simultaneously adding halide ions and silver ions while controlling the pH and pAg in the mixing vessel while taking into account the critical growth rate of silver halide crystals.

By this method, monodisperse silver halide grains having a regular crystal form and grains which are almost uniform can be obtained.

The crystal habit of the silver halide grains according to the present invention is generally a cubic habit, but regular grains such as octahedra and tetradecahedrons obtained by the presence of various compounds in the grain growth process. It may have a different crystal form, or may have an irregular crystal form such as a sphere or a plate. In these particles, any ratio of (100) plane to (111) plane can be used. Further, it may have a composite form of these crystal forms, and particles of various crystal forms may be mixed.

When cubic particles are used in the present invention, higher sensitivity is obtained, which is preferable.

The silver halide emulsion of the present invention may be used as a mixture of two or more kinds of silver halide emulsions formed separately.

The metal ion added to the silver halide photographic emulsion used in the present invention is not particularly limited, but preferably cadmium, lead, copper, zinc, rhodium, palladium, iridium, platinum, thallium, iron or the like is used, In particular, iridium, cadmium, and lead are preferable because they can increase the sensitivity. These metal ions are preferably used in the form of a metal salt or a metal complex salt.

The addition amount is as described above per mol of silver halide
The amount is 10 ^-8 to 10 ^-5 mol, and in this range, the optimum amount is appropriately selected in combination with the grain size of the silver halide grains, crystal habit, and further in combination with other additives such as a sensitizing dye. Generally, if the amount is less than 10 ^-8 mol, the effect of the present invention cannot be sufficiently exerted,
If the amount exceeds 10 ^-5 mol, other photographic properties such as desensitization may be adversely affected.

The metal ion used in the present invention may be added at any stage of nucleation, grain growth and physical ripening of the silver halide grain of the present invention, or may be dividedly added.
These metal ions are used in the form of a metal salt or a metal complex salt, and these compounds are dissolved in water or a suitable solvent and added.

The high chloride silver halide emulsion is very excellent in developability, but has the drawbacks of slightly high fog and low sensitivity. In a color photographic light-sensitive material, a large amount of anti-irradiation dye is used for improving sharpness, and the sensitivity of the blue-sensitive emulsion layer is further lowered. Therefore, development of a high chloride silver halide blue sensitive emulsion having sufficient sensitivity has been desired.

By sensitizing the high chloride silver halide emulsion doped with metal ions according to the present invention with the compound of the general formula [I], a silver halide emulsion having sufficiently high sensitivity and low fog can be obtained. Was given.

Among these mercapto compounds, a [II b] type mercaptotetrazole compound is particularly preferable. The above compounds are available from the Journal of Chemical Society (J.
Chem.Soc.) 49 , 1748 (1927) Journal of Organic Chemistry (J.Org.Chem) 39 , 2469 (1965)

The compound represented by the general formula [II] (hereinafter appropriately referred to as "the compound of the present invention" or the compound [II]) is contained in the silver halide emulsion layer in water or an organic compound miscible with water. It may be added after being dissolved in a solvent (for example, methanol, ethanol, etc.). The compound [II] may be used alone, or another compound represented by the general formula [II],
Alternatively, it may be used in combination with a stabilizer other than the compound represented by the general formula [II], or an antifoggant. Various stabilizers and antifoggants that can be used in combination will be described later.

The compound [II] is preferably added after the formation of silver halide grains. The time of addition may be any time, for example, from the end of silver halide grain formation to the start of chemical ripening, during chemical ripening, at the end of chemical ripening, or from the end of chemical ripening to coating. Preferably, it is added during chemical ripening, at the end of chemical ripening, or from the end of chemical ripening to the coating. The addition may be carried out all at once or may be added in a plurality of times.

It may be added directly to the silver halide emulsion or the silver halide emulsion coating solution, or to the coating solution for the adjacent non-photosensitive hydrophilic colloid layer, and then added by diffusion during multilayer coating.

In the present invention, the reason why the compound represented by the general formula [II] is used is that a silver halide emulsion containing a high silver chloride doped with a metal ion is sensitized with a compound represented by the general formula [I]. Sensitivity can be obtained, but after chemically ripening this emulsion, set the emulsion by cooling, store refrigerated in this state, redissolve it every time for a certain period of time, coat it on a support and examine its performance Then, sensitivity change and softening of the legs were observed. Therefore, this is to prevent performance fluctuation due to storage after such setting. This performance variation is particularly large when the emulsion doped with a metal ion is sensitized with the compound of the general formula [I], but the addition of the compound of the general formula [II] improves the adverse effect such as desensitization. To be done.

The silver halide emulsion of the present invention can be chemically sensitized by a conventional method. That is, a sulfur sensitizing method, a selenium sensitizing method, a reduction sensitizing method, a noble metal sensitizing method using a gold or other noble metal compound can be used alone or in combination.

In the color development processing, the emulsion layer of the light-sensitive material of the present invention undergoes a coupling reaction with an oxidant of an aromatic primary amine developer (for example, p-phenylenediamine derivative, aminophenol derivative, etc.) to form a dye. Dye forming couplers are used.

The dye-forming couplers are usually selected such that for each emulsion layer a dye is formed that absorbs the light in the sensitive spectrum of the emulsion layer, with the blue-sensitive emulsion layer containing a yellow dye-forming coupler and a green dye-forming coupler. A magenta dye-forming coupler is used in the light-sensitive emulsion layer, and a cyan dye-forming coupler is used in the red-sensitive emulsion layer.

However, the silver halide color photographic light-sensitive material may be prepared by using the combination different from the above combination depending on the purpose.

It is desirable that these dye-forming couplers have a group called a ballast group, which has a carbon number of 8 or more, which makes the coupler non-diffusible. Also, these dye-forming couplers are 1
Either four equivalents, in which four silver ions need to be reduced in order to form a molecular dye, or two equivalents, in which only two silver ions need to be reduced may be used.

DIR, which releases a development inhibitor to these dye-forming couplers with development, improving image sharpness and image graininess
Couplers may be used in combination. At this time, it is preferable that the DIR coupler is of the same system as the dye formed from the coupler is the same as the dye formed from the dye-forming coupler used in the same emulsion layer. It may be one that forms the dye. Instead of the DIR coupler, a DIR compound which undergoes a coupling reaction with an oxidized form of the developing agent in combination with or in combination with the coupler to generate a colorless compound and simultaneously release a development inhibitor may be used.

The DIR coupler and the DIR compound used include those in which an inhibitor is directly bonded to the coupling position, and those in which the inhibitor is bonded to the coupling position via a divalent group, and within the group which is released by the coupling reaction. (A timing DIR coupler and a timing DIR compound) in which an inhibitor is released by an intramolecular nucleophilic reaction, an intramolecular electron transfer reaction, or the like. Further, as the inhibitor, one that is diffusible after withdrawal and one that is not so diffusible can be used alone or in combination depending on the application. A colorless coupler which performs a coupling reaction with an oxidized aromatic primary amine developer but does not form a dye can be used in combination with a dye-forming coupler.

As the yellow dye-forming coupler, an acylacetanilide coupler can be preferably used. Among them, benzoylacetoanilide compounds and pivaloylacetoanilide compounds are advantageous.

Examples of magenta dye-forming couplers include 5-pyrazolone couplers, pyrazolobenzimidazole couplers,

The oil-in-water emulsion dispersion method can be applied to disperse a hydrophobic additive such as a coupler, and usually has a low boiling point, and / or a water-soluble organic solvent having a high boiling point of about 150 ° C. or higher in an organic solvent. After being dissolved in combination, using a dispersing agent such as a stirrer, a homogenizer, a colloid mill, a flow jet mixer, and an ultrasonic device with a surfactant in a hydrophilic binder such as an aqueous gelatin solution, after emulsion dispersion, It may be added to the desired hydrophilic colloid layer. A step of removing the low-boiling organic solvent after or simultaneously with the dispersion may be included.

Example 1 To a vigorously stirred gelatin aqueous solution, 0.5 mol of 2 mol / silver sulfate aqueous solution and 0.5 mol of 2 mol / sodium chloride aqueous solution were added over 150 minutes to prepare a pure silver chloride emulsion (Em-
1) was adjusted. Keep the temperature at 60 ° C during the addition and keep the PAg at 6.0
I tried to keep it. As a result of electron microscope observation, the average grain size of this emulsion was 0.65 μm and the crystal habit was cubic.

Then, 80 minutes after the addition of the sodium chloride and silver sulfate solutions was started, 3 × 10 ^-6 mol of K ₂ per mol of silver halide was added.
An iridium ion-doped silver chloride emulsion (Em-2) was prepared in the same manner as Em-1 except that IrCl ₆ was added. The average grain size was 0.65 μm, and the crystal habit was cubic.

Silver halide 1 as a sulfur sensitizer for Em-1 and Em-2
1 × 10 ^-5 mol of sodium thiosulfate was added per mol to perform chemical ripening, and 5 minutes before the completion of the chemical ripening, it was divided into two parts. One was sensitizing dye BS-3 and the other was comparative dye A halogenated. 10 ^-4 mol per mol of silver was added, and at the end of the chemical ripening, each was again divided into two, and the compound [II b]-
7 and ST-1 on the other hand 5 × 10 ^-4 per mol of silver halide
After adding mols and stirring sufficiently, the emulsion was cooled and set, and then stored in a refrigerator. Thus, a blue-sensitive emulsion was prepared. After storage for a certain period of time, this was melted, and 0.15 mol of color stain inhibitor (HQ-1) per 1 mol of this coupler and yellow coupler (YC-1) was added to dibutyl phthalate (hereinafter DB
Dissolved and dispersed in P) and silver halide 1
The blue-sensitive emulsion was mixed so that the amount of coupler was 0.3 mol per mol. The coating solution thus prepared was applied onto a photographic paper support coated with polyethylene containing titanium oxide, and a protective layer was applied to prepare a sample.
Coating amount, and the silver halide to adjust the 0.4 g / m ² gelatin as metallic silver so that ^{1g / m 2 3.0g / m 2} , the protective layer to the emulsion layer.

Each of the samples thus prepared was exposed to the light intensity scale and subjected to the following processing steps.

(Processing step) Color development 35 ° C. 45 seconds Bleach fixing 35 ° C. 45 seconds Water washing 30 to 35 ° C. 90 seconds Dry 60 to 68 ° C. 60 seconds The compositions of the color developing solution and the bleach-fixing solution used are as follows. (Per 1) (color developer) (Bleaching fixer) With respect to the density of the obtained dye image, the reflection density was measured with a PDA65 densitometer (manufactured by Konica Corporation) with blue monochromatic light, and the results in Table 1 were obtained.

In the table, the sensitivity is the reciprocal of the exposure amount that gives a density of 1.0, and is expressed as a relative value with the sensitivity of Sample 1 being 100. γ ₁ is the concentration
Represents a leg gradation of 0.2 to 0.7.

As is clear from Table 1, Sample 5 using the emulsion Em-2 of the present invention has high sensitivity and good performance (sensitivity fluctuation and γ
₁ shows variation with small), the emulsion without emulsion also doped doped with iridium emulsions with BS-3 is also Izure also reduced sensitivity increase and gamma ₁ are seen by the set storage, in particular doped with iridium emulsion Then, this tendency is strong.

Further, a tendency of sensitization is also seen in the comparative dye. When Comparative Compound ST-1 was used as a stabilizer, desensitization was observed, but there was no effect on sensitivity fluctuation due to set storage and leg softening.

Example 2 Using a method similar to the preparation of Em-2 of Example 1, CdCl 2
₂ per mol of silver halide 3 × 10 ^-6 Morudopu silver chloride emulsion Em-3 and PbCl ₂ per mol of silver halide 3 × 1
Emulsion Em-4 doped with 0 ^-6 mol and emulsion Em-5 doped with FeCl ₂ at 3 × 10 ^-6 mol per mol of silver halide were prepared.

Chemical ripening was carried out in the same manner as in Example 1 to prepare a coated sample and the performance of the emulsion was evaluated.

 The results are shown in Table 2.

 The sensitivity was shown as a relative value with sample 9 being 100.

As is clear from Table 2, iridium, cadmium,
Emulsions doped with lead and iron ions have high sensitivity,
The sensitivity fluctuation and γ ₁ fluctuation due to storage of the set were small, and good performance was exhibited. In an emulsion doped with iron ions, the γ ₁ fluctuation is small, but the value is low. Doping with iridium, cadmium, or lead ions is a preferred embodiment of the present invention.

Example 3 In the same manner as in Example 1, samples were prepared and evaluated by changing the types of sensitizing dye and stabilizer. The results are shown in Table 3. The sensitivity was shown as a relative value with sample 14 as 100.

As is clear from Table 3, the sensitizing dyes according to the present invention are
Both show excellent sensitivity.

In the case of the comparative dye B, although the sensitivity is high, the sensitivity variation and softening during storage of the set can be suppressed by using either the stabilizer [IIb] -5 according to the present invention or the comparative compound ST-2. I couldn't. As the stabilizer, a compound represented by the general formula [II-
The compounds represented by any of a] and [II b] have the effect of preventing sensitivity fluctuations and softening during storage of the set, but the compounds represented by [II b] are particularly preferred because of their large effects.

Example 4 According to the method for adjusting Em-1 and Em-2 of Example 1, Em-1,
A blue sensitive emulsion of Em-2 was prepared. Also, Em-1 of Example 1
The silver chloride emulsion (Em-
6) was adjusted. Sodium thiosulfate was added to this emulsion as a sulfur sensitizer, and 5 minutes before the completion of chemical ripening, this was divided into sensitizing dye (GS-1) on one side and (RS-
1) was added, and the stabilizer of [II b] -7 was added at the end of the chemical ripening. Thus, a green-sensitive emulsion (with GS-1 added) and a red-sensitive emulsion (with RS-1 added) were prepared.

Using this emulsion, a coated sample was prepared according to the following procedure, the emulsion prepared above was stored in a refrigerator, and one week later, a coated sample was prepared in the same manner.

The following seven layers were successively coated on a polyethylene-coated paper support to prepare a silver halide color photographic light-sensitive material. Here, the amount of each compound is shown as a value per 1 m ^{2 of the} color photographic light-sensitive material.

The color paper thus produced was exposed through a color negative and developed according to the processing steps of Example 1. Adjust the exposure conditions with Samples 45 and 47, and under the same conditions as Sample 45,
When 46 is printed under the same conditions as sample 47, sample 48
45, 47, and 48 produced the same high-quality color prints, but sample 46 produced strong prints of yellow, especially skin tones.
When changing the exposure conditions and printing, sample 46 also produced a fairly good color print.
It was also yellowish and clearly inferior to other samples.

Example 5 In the method for preparing the silver halide emulsion of Example 1, Table 5
Em-7 to 14 were prepared by replacing the sodium chloride aqueous solution in Em-1 and 2 with a mixed aqueous solution of sodium chloride and potassium bromide so as to have the composition shown in (1). By adjusting the addition rates of the silver salt aqueous solution and the mixed halide salt aqueous solution, a silver halide emulsion having an average grain size of 0.65 μm and a cubic crystal habit was obtained. Using this emulsion, the sensitizing dye BS-2,
Using the stabilizer [II b-7], chemical aging was performed in the same manner as in Example 1 to evaluate the sensitivity and γ ₁ .

Sensitivity was expressed as relative sensitivity with the sensitivity of NO53 at 0 days of set storage as 100.

As is clear from Table 5, as the content of silver chloride decreases, the sensitivity increases at first, but when it reaches 10 mol%, it desensitizes as the content of silver chloride decreases, and becomes softer. The tendency of is becoming noticeable. In the iridium ion-doped emulsion according to the present invention, no tendency of desensitization or softening is observed, and it can be seen that preferable characteristics are obtained as a result of chemical ripening. However, if the silver chloride content is
When it is 70 mol%, from the viewpoint of developability, it is no longer possible to maintain the preferable characteristics, and the characteristic that the performance fluctuation due to set storage is small is maintained, but the effect of the present invention is sufficiently exerted. Is hard to say.

Example 6 Em-8 was prepared in the same manner as in Example 5, and the sensitizing dye was added to BS.
-3, BS-15, BS-30, BS-32, BS-34, BS-36, BS-
The sensitivity of the emulsion chemically ripened in the same manner as in Example 5 except that the sensitizing dyes were changed to 37 and BS-38 and the change in γ ₁ were evaluated. It was found that the effect of the present invention that the fluctuation of the sensitivity and γ ₁ due to the set storage of the emulsion is extremely small is exhibited.

Example 7 Em-8 was prepared in the same manner as in Example 5, and the stabilizer was IIa.
-1, II a-2, II a-6, II a-9, II a-10, II a-12, II b
-1, IIb-5, IIb-7, IIb-8, IIb-11, IIb-12, except that the sensitivity of the chemically aged emulsion was set and stored, _When the change of ₁ was evaluated,
It was found that the use of any of the stabilizers provides the effects of the present invention that the sensitivity is high and the sensitivity due to the set storage of the emulsion and the fluctuation of γ ₁ are extremely small.

[Effects of the Invention] As is clear from Tables 1 to 4, the present invention sensitizes a silver halide emulsion having a high silver chloride content with a metal ion and sensitizes it with a compound represented by the general formula [I]. The desired photographic performance obtained by the above is that by adding the compound represented by the general formula [II], the performance fluctuation after storage with time can be made extremely small. The performance fluctuation is
When the compound represented by the general formula [I] and the metal-doped emulsion are used in combination, they are remarkably exhibited. Even if the compound represented by the general formula [I] is used, the performance fluctuation is small in the emulsion not doped with metal ions. Further, when a comparative dye other than the general formula [I] is used, the sensitivity is not high and the performance variation is not remarkable.

Therefore, according to the present invention, since it is possible to obtain an image with high sensitivity and small performance fluctuation, rapid development, and stable quality, it is particularly preferably used as a color photographic light-sensitive material.
