Description

The present invention relates to a color development processing method for a silver halide color photographic light-sensitive material (hereinafter referred to as a light-sensitive material), and more specifically, it relates to a change in replenishment amount and the influence of evaporation. The present invention relates to a novel processing method, which has less dependence on bromide ion concentration and processing time dependency to occur, does not impair promptness, and provides a dye image having excellent light brownness and high storage stability,
In particular, the present invention relates to a treatment method with a small replenishment amount and high treatment stability.

[Prior Art] The processing of a light-sensitive material basically comprises two steps of color development and desilvering, and desilvering comprises a bleaching and fixing step or a bleach-fixing step. In addition to this, rinse treatment, stabilization treatment, and the like are added as additional treatment steps.

In color development exposed silver halide is reduced to silver while the oxidized aromatic primary amine developing agent reacts with the coupler to form a dye. During this process, halogen ions generated by the reduction of silver halide are eluted and accumulated in the developer. Separately, components such as inhibitors contained in the silver halide photographic light-sensitive material are also eluted and accumulated in the color developing solution. In the desilvering step, silver produced by development is bleached with an oxidizing agent, and then all silver salts are removed from the photographic light-sensitive material as soluble silver salts with a fixing agent. There is also known a one-bath bleach-fix processing method in which the bleaching step and the fixing step are collectively processed at the same time.

In the color developing solution, the development-inhibiting substance is accumulated by developing the photographic light-sensitive material as described above, while the color-developing agent and benzyl alcohol are consumed or accumulated in the photographic light-sensitive material and taken out. The concentration decreases. Therefore, in the development processing method in which a large amount of silver halide photographic light-sensitive material is continuously processed by an automatic developing machine or the like, the components of the color developing solution are kept within a certain concentration range in order to avoid a change in development finish characteristics due to a change in component concentration. Means are needed. As such means, a method of replenishing a replenisher for diluting unnecessary increasing components and supplementing deficient components is usually adopted. Since the replenishment of this replenisher inevitably causes a large amount of overflow and is discarded,
This method has become a major economic and pollution problem. Therefore, in recent years, in order to reduce the overflow solution, a so-called concentrated low replenishment system in which these replenishers are concentrated and replenished in small amounts is widely used. Alternatively, a method of adding a regenerant to the overflow solution and using it again as a replenisher is also available. Proposed and put to practical use.

[Problems to be Solved by the Invention] These are methods in which the replenishment amount is substantially reduced. If the replenishment amount is extremely reduced, the organic inhibitor and halogen ion concentration eluted in the developer will undergo a large concentration change even with a slight replenishment amount error.
In addition, it is also susceptible to the effect of concentration due to evaporation, and normally the concentration of the above-mentioned fatigue accumulation increases. For example, when the halogen ion concentration rises, the development reaction is suppressed, or the leg portions of the characteristic curve are further suppressed, which causes a problem of high contrast. To avoid this, halogen ions are removed from the overflow solution by ion exchange resin or electrodialysis, and a regenerant is added to replenish the deficient components generated during development and the deficient components lost during the regeneration process, and regenerated as a replenisher. The method to use is proposed.

Regeneration by these ion exchange resins and electrodialysis and concentrated low replenishment methods are easily affected by fluctuations in bromide ion concentration due to the effects of evaporation and regeneration operations. Separately, there is a difference in processing amount, especially at the beginning of the week when orders are high and orders are received. The difference between the high season and the off-season is the maximum difference of 1: 5, and the composition of the treatment liquid is drastically different because of the influence of evaporation and the difference in the amount of replenisher. There is a drawback that ends up.

Therefore, in the low replenishment process and the regeneration method, we are trying to make the composition constant by quantitatively analyzing the components for each regeneration, and therefore it is difficult to carry out these regeneration processes and low replenishment processes in a laboratory or minilab without special skills. There are many things.

Such problems are mainly caused by changes in the bromide ion, which is a development inhibitor.For example, by reducing the amount of silver bromide in a photographic material, the amount of accumulated bromide ion is reduced, or evaporation or replenishment is performed. It has also been proposed to reduce the variation in the concentration of bromide ions due to the error in the amount (see Japanese Patent Application Nos. 59-173189 and 59-205540, etc.). It is presumed that the problem can be solved by improving the developability by reducing the average grain size of silver halide or reducing the amount of coated silver. However, it is a conventional developing agent 3-methyl-4-amino-N- In the color developing solution using ethyl-N-β-methanesulfonamide ethylaniline, when the developing property is improved, it becomes more susceptible to the influence of the fluctuation of the bromide ion concentration in the developing solution. The expectation that stability is impaired becomes result of the inverse.

However, it is an important issue to shorten the processing time and increase the processing stability.

Conventionally, in color paper processing consisting essentially of silver chlorobromide emulsion, color development is 33 ° C, 3 minutes 30 seconds-bleach-fixing 33 ° C, 1
Minutes 30 seconds-Washing 3 minutes (or stabilizing treatment 3 minutes) -Drying. The total processing time is generally about 8 minutes, but the strong demand of the times is the above-mentioned low replenishment in the economic sense, but short-time processing is also strongly demanded from the viewpoint of shortening the delivery time. ing.

However, as described above, speeding up and stabilization of processing or low replenishment are contradictory problems, and can be said to be a trade-off relationship.

That is, if the replenishment rate is lowered, the concentration of bromide ion as an inhibitor and the concentration of a sulfur compound or a mercapto compound as an emulsion stabilizer are increased, impairing the rapidity and impairing the processing stability.

However, various measures have conventionally been taken to speed up color development for speeding up. In particular, the above-mentioned developing agents that have been used as the most suitable developing agents for silver chlorobromide emulsions for a long time have low hydrophilicity, so that the penetration of the color developing agent into the light-sensitive material is slow and Various penetrants have been studied, and for example, a method of adding benzyl alcohol to a color developing solution to accelerate color developing is widely used. However, in this method, if the treatment is not performed at 33 ° C for 3 minutes or more,
The color was not sufficiently developed, and in addition to that, there was a drawback that it was easily affected by the delicate bromide ion concentration. A method of increasing the pH of the color developing solution is also known, but when the pH is 10.5 or more, the oxidation of the color developing agent becomes remarkably fast, and there is no suitable buffer solution, so it is susceptible to pH changes and stable. However, there is a problem in that the photographic characteristics described above cannot be obtained and the dependence of processing time increases.

A method of increasing the activity by increasing the color developing agent in the color developing solution is also known, but it is said that the color developing agent becomes an expensive processing solution because it is very expensive, and at the same time, the main agent is difficult to dissolve in water and easily precipitates. Instability also occurs and it is not practically usable.

On the other hand, there is known a method of preliminarily incorporating a color developing agent in a light-sensitive material in order to achieve rapid color development. For example, a method of incorporating a color developing agent in the form of a metal salt is known (US Pat. No. 3,719,492), but with this method, the raw storability of the light-sensitive material is poor and fogging occurs before use, and fogging during color development. It had the drawback of being easy.

Furthermore, in order to inactivate the amine part of the color developing agent,
For example, a method of forming a Schiff salt and incorporating a color developing agent (US Pat. No. 3,342,559, Research Disclosure, 1976).
No. 15159) is also known, but these methods have a drawback that color development cannot be started because the color developing agent is not hydrolyzed with alkali, and the color development is rather delayed.

Furthermore, when the color developing agent is directly incorporated, in addition to the drawback that the emulsion during storage is fogged because of the unstable color developing agent, the emulsion film quality becomes weak and various processing problems occur. there were.

Furthermore, it is known that 3-pyrazolidones are added to a black-and-white developer containing a developer such as hydroquinone to accelerate development (eg, LFA Mason, Photographi

Although described in British Patent No. 767,704, in the technology described in the above-mentioned patent specification, the black-and-white light-sensitive material or the reversal color light-sensitive material is incorporated, the purpose is to promote only black-and-white development, Also, JP-A-53-52422
In order to prevent a decrease in sensitivity of a color light-sensitive material containing a 2-equivalent magenta coupler having an oxy-type organic split-off group at an active site in an unexposed state, 3-pyrazolidones are contained in the light-sensitive material. However, these technologies are
It is not suitable as a rapid method for stabilizing the color development processing with low replenishment processing.

Further, as a method of accelerating color development by a conventionally known accelerator, US Pat. Nos. 2,950,970 and 2,515,1

The compounds described in JP-B No. 51-12322, JP-B No. 51-12322 and JP-B No. 55-49728 were examined, but most of the compounds have insufficient accelerating effect, and compounds showing a high accelerating effect are fogged. It is not suitable as a method for improving the processing stability as well as having the drawback that it is produced.

Further, providing a substantially light-insensitive silver halide emulsion layer in a light-sensitive light-sensitive material to accelerate development is disclosed in JP-A-50-

Known as 577, OLS 2,622,922, etc., its function is to adsorb unwanted halogens released during development and development inhibitors such as unwanted leaving groups of DIR couplers and DAR couplers. It does not accelerate development, but its development promoting effect is small, and although it is effective for fluctuations in iodide ion concentration, no processing stabilizing effect is obtained for fluctuations in bromide ion concentration. There wasn't.

On the other hand, the speed of color development differs depending on the type of para-phenylenediamine derivative used and is said to depend on the redox potential. Among these color developing agents, N,
N-diethyl-P-phenylenediamine sulfate and 3-methyl-4-
N-alkyl-substituted low water-soluble color developing agents such as amino-N, N-diethylaniline hydrochloride have high developing activity and can be accelerated, but the dark brown color of the coloring dye after processing is not preferable. It is known. On the other hand, it is said to be preferable because of its high developing activity. (U.S. Pat.No. 3,656,950,
(See No. 3,658,525) 3-Methyl-4-amino-N-ethyl-N-β
-Methoxyethylaniline-di-p-toluenesulfonate is certainly quick, but bromide ion concentration stability is not obtained and yellow stain is remarkably generated in the unexposed area of the photographic light-sensitive material after processing. In particular, when processed for a short time, there is a drawback that the color developing agent remains and causes the generation of rough stains, so that it cannot be used in rapid processing.

On the other hand, 3-methyl-4 in which a water-soluble alkylsulfonamide group or hydroxyalkyl group was introduced into the N-alkyl group
-Amino-N-ethyl-β-methanesulfonamide ethylaniline sesquisulfate monohydrate and 3-methyl-4
-Amino-N-β-hydroxyethylaniline sulphate has a redox potential as seen in Photographic Science and Engineering Vol.8, NO 3.5-June, 1964, P.125-137. It was said that there was not much difference in the half-wave potentials shown and that both had weak developing activities.

Therefore, there is almost no color developing agent that can substantially develop the silver chlorobromide emulsion and has excellent storage stability of the dye image, and generally 3-methyl-4-amino-N-ethyl-N-β-methane. Sulfonamidoethylaniline sulphate has achieved this goal by using it with benzyl alcohol.

However, in this case, as described above, it is easily affected by the change in the bromide ion concentration. Further, in the concentrated and low replenishment process in which the replenisher is reduced, another problem is an increase in mixing and accumulation of other treatment liquid components. This is because the tank liquid is renewed with the replenishing liquid at a low rate due to the decrease in the replenishing amount, and the service life of the liquid is prolonged.
Contamination of other processing solutions is caused by so-called back contamination in which the processing solution components immediately after development are brought into the color developing solution by splashing of the adjacent processing solution in the processor, a transport leader, a belt or a hanger for hanging the film. Be done. Among these accumulated mixed components, the thiosulfate ion as the fixing agent accelerates the development. That is, this problem particularly strongly occurs when the bleach-fixing process is performed directly after color development. Particularly by promoting the shoulder of the photographic characteristic curve, a significant increase in contrast occurs. Further, an increase in the content of a metal salt as a bleaching agent, especially a ferric salt, promotes the decomposition of hydroxylamine as a preservative to generate ammonia ions. This decomposition reaction is greatly accelerated above 30 ° C. The generation of this ammonia ion promotes physical development similarly to thiosulfate ion, and has a drawback that high contrast is obtained.

Therefore, even if the amount of replenishment is reduced to improve economic and environmental pollution, rapid processing is possible, the photographic performance is maintained constant, and the active ingredient is decomposed even when the processing solution is used for a long time. At present, there is a strong demand for the emergence of a color developing solution that can be stably processed without changing the photographic processing performance.

The object of the present invention is to maintain constant and appropriate photographic performance for a long period of time without being affected by changes in the bromide ion concentration even when processed with a low replenishing amount using a color developing solution, and to obtain a coloring dye or An object of the present invention is to provide a rapid and stable method for processing a silver halide color photographic light-sensitive material in which an uncolored portion does not turn brown or discolor even when stored for a long period of time.

Other objects of the present invention will be apparent from the following description of the present specification.

[Means for Solving the Problem] As a result of various studies conducted by the inventor in order to achieve the above-mentioned object of the present invention, a specific color development which is hardly affected by the bromide ion concentration in the development of a specific silver halide. Although they succeeded in finding the main drug, they encountered a obstacle that the storage stability of the obtained color-forming dye deteriorates, and further studied a method for solving the obstacle. As a result, in the method of developing a silver halide color photographic light-sensitive material, at least one light-sensitive emulsion layer is provided with at least a red-sensitive emulsion layer, a green-sensitive emulsion layer and a blue-sensitive emulsion layer on a reflective support. In the method for developing a silver color photographic light-sensitive material, the silver halide emulsions of the red-sensitive emulsion layer, the green-sensitive emulsion layer and the blue-sensitive emulsion layer are substantially silver chlorobromide emulsions, and the binder film swelling speed T1 A silver halide color photographic light-sensitive material having a ratio of / 2 of 30 seconds or less is prepared by using the following compound (1),
Method for processing a silver halide color photographic light-sensitive material, which is characterized in that development processing is carried out at 30 ° C. or more and 150 seconds or less using a color developing solution containing at least one of (2) and (3) Compound (1) Compound (2) Compound (3) It has been found that the above-mentioned object can be achieved by.

The present inventors have found that when developing a color photographic light-sensitive material using a specific silver halide, that is, an emulsion mainly composed of silver chlorobromide (in particular, a silver bromide content of 90 mol% or less), a specific color developing agent is N-
We have found the surprising fact that only when using a hydroxyalkyl-substituted-p-phenylenediamine derivative, the obtained dye concentration hardly changed even when the bromide ion concentration was changed. The characteristics of this color developing agent are silver iodide
This is not possible with a color photographic light-sensitive material substantially containing a silver iodobromide emulsion containing 0.5 mol% or more. Conventionally, this type of color developing agent has been used exclusively for the development of a silver iodobromide emulsion. This is unexpected, and the fact that even when the bromide ion concentration is greatly increased during the development of a color photographic light-sensitive material using a substantially silver chlorobromide emulsion, the development speed is not delayed is unexpected. It is not something that can be understood from the oxidation-reduction potential and half-wave potential of common color developing agents, and it is unlikely that this can occur unless the optimal balance between development speed and coupling speed is maintained, which is surprising. Was that.

However, the present inventor has encountered the following obstacles. It is rapid when a specific N-hydroxyalkyl-substituted-p-phenylenediamine color developing agent is used, and it does not undergo changes in bromide ion concentration. It was found that the replenishing amount can be greatly reduced and the processing stability is remarkably high, but the storage stability of the obtained color forming dye, particularly the light brown property, is deteriorated. . The storage stability of the dye image is fatal, especially in the case of a printing material, which is a serious obstacle.

The present inventor further diligently worked to solve this problem,
We found that it is not because the storage stability of the dye itself is low, but because the color developing agent easily remains in the color photographic light-sensitive material, and in particular, it can be solved by performing the color developing time in a short time. . However, shortening the color development time cannot be achieved unless the development processability of the color photographic light-sensitive material is sufficiently improved, and cannot be unconditionally shortened.However, the low replenishment and processing without damaging the storage stability of the dye image In order to achieve the stability, it was found that the minimum condition is that the color developer of the present invention is processed at 30 ° C. or higher and within 150 seconds.

In this case, there is a problem that a conventional photographic light-sensitive material as it is cannot develop a sufficient photographic image due to insufficient development time. Therefore, the present inventor has further studied, and the silver halide emulsions of all the light-sensitive emulsion layers are substantially used for the low replenishment processing using the color developing agent of the present invention without being affected by the increase of the bromide ion concentration. A color photographic light-sensitive material which is a silver chlorobromide emulsion and has a binder film swelling speed T1 / 2 of 30 seconds or less is treated with a developing solution containing a specific N-hydroxyalkyl-substituted-p-phenylenediamine derivative. By improving the developing speed by rapidly developing the color photographic light-sensitive material in the range of 30 ° C or more and 150 seconds or less, the object of the present invention can be achieved without impairing the stability of the dye image. It was a successful one.

In the present specification, “substantially silver chlorobromide emulsion” means that a small amount of silver iodide may be contained in addition to silver chlorobromide.
For example, it means that 0.3 mol% or less, more preferably 0.1 mol or less, of silver iodide may be contained. However, silver chlorobromide emulsions containing no silver iodide are most preferred in the present invention.

Hereinafter, the present invention will be described in more detail.

The hydrophilic binder used for coating the silver halide of the color photographic light-sensitive material is usually gelatin, but a polymer may be used in some cases, and the film swelling speed T
1/2 must be less than 30 seconds and the film swelling rate T1 / 2 of the binder can be measured according to any technique known in the art, eg A. Green and GI.
P.Levenson.Photo.Sci.Eng.Vol.19.No.2, p124 to 129 can be measured by using a swellometer (swelling meter) of the type described, and T1 / 2 is 30 in color development. ℃,
90% of the maximum swollen film thickness reached when the treatment is performed for 3 minutes and 30 seconds is defined as the saturated film thickness, and is defined as the time until the film thickness reaches half of this (see Fig. 1).

The binder of the photographic constituent layers used in the silver halide color photographic light-sensitive material of the present invention has a swelling speed T1 / 2 of 30 seconds or less, and the smaller the better, the more preferable the lower limit is. Since failure is likely to occur,
2 seconds or more is preferable. Particularly preferably, it is 20 seconds or less, and most preferably 15 seconds or less. When it is longer than 30 seconds, the storage stability of the dye image is low and sufficient dye formation cannot be obtained within 150 seconds. The film swelling speed T1 / 2 can be adjusted by the amount of the hardener used.

The light-sensitive emulsion layer of the silver halide color photographic light-sensitive material processed according to the present invention consists entirely of silver chlorobromide emulsion.
In the silver chlorobromide, the smaller the mol% of silver bromide is, the more sufficient dye formation can be obtained even in a short time of color development.
90 mol% or less is preferable, and 70 mol% or less and 40 mol% or more is the most preferable result.

In the present invention, when the color photographic light-sensitive material of the present invention is continuously processed at a replenishing rate of 250 m / m ² or less, the effect of the present invention is satisfactorily achieved, and further 200 m / m ²
Especially good when: 20-180m
Particularly good at / m ² .

Furthermore, the smaller the amount of coated silver, the more preferable the point is that there is no delay in development with respect to the increase in bromide and sufficient dye formation can be performed in a short time, and the maximum effect is obtained when it is 1 g / m ² or less, particularly 0.8 g / m ² or less. can get. Color development processing is over 30 ℃, 150
Seconds or less, preferably 33 ° C or more, 120 seconds or less, most preferably 35 ° C or more, 90 seconds or less, and the storage stability of the dye is deteriorated when a treatment of 30 ° C or more and 150 seconds or more is performed. . Especially, the processing time is more important than the temperature.
If it exceeds 2 seconds, the light brownness of the cyan dye is remarkably increased, which is not preferable. The processing temperature is not the storage stability of the dye but rather the temperature for raising the development in a short time.
The higher the temperature is from 50 ° C. to 50 ° C., the shorter the treatment is, which is more preferable. The temperature is from 33 ° C. to 48 ° C., and the treatment from 35 ° C. to 43 ° C. is most preferable.

The color developing agent of the present invention is at least one compound selected from the compounds (1), (2) and (3).

Since the solubility of the color developing agent of the present invention in water is extremely high, the amount thereof is preferably used in the range of 1 g to 100 g, more preferably 3 g to 30 g, per processing liquid.

These N-hydroxyalkyl-substituted-p-phenylenediamine derivatives of the present invention can be easily synthesized by the method described in Journal of American Chemical Society, Volume 73, Item 3100 (1951).

The color developer of the present invention preferably has a bromide ion concentration of 5 × 10 ⁻³ mol or more, but in the present invention, the higher the bromide content, the more the replenishment amount can be lowered, which is preferable. In the conventional developing method, it was said that bromide was more preferable as it suppressed the development reaction and was lower, but in the combination of the color photographic light-sensitive material and the developing solution of the present invention, the higher the bromide is, the more preferable it is, and the object of the present invention was achieved. To be done. In other words, in the present invention, the replenishment amount can be reduced because it is less affected by bromide.

The bromide is preferably 1 × 10 ^-2 mol or more, particularly preferably
1.5 × is 10 ^-2 mol or more is not preferable due to the effect of bromide ion concentration for bromide ion concentration is too high, the development suppression Dehajimeru 6 × 10 ^-2 mol or more. The chloride concentration has no effect.

The color photographic light-sensitive material of the present invention is a multi-layer color photographic light-sensitive material having three or more layers each containing a blue-sensitive emulsion layer, a green-sensitive emulsion layer and a red-sensitive emulsion layer. / 2, that is, the maximum effect is exhibited when the film swelling speed T1 / 2 is 30 seconds or less, but the total film thickness is 14
μm or less, preferably 13 μm or less, particularly preferably 12 μm
Although it is m or less, in any case, T1 / 2 is preferably 30 seconds or less.

[Examples] Specific examples of the present invention will be described below, but embodiments of the present invention are not limited thereto.

Example 1 The following layers were sequentially coated on a polyethylene-laminated paper support from the support side to prepare silver halide color photographic light-sensitive material samples Nos. 1 to 25.

Layer 1 ... 1.2 g / m ² gelatin, 0.32 g / m ² (silver equivalent, the same applies hereinafter) blue-sensitive silver halide gelatin emulsion (silver halide composition and average grain size are shown in Table 1), 0.50 g

Layer 4 ... an intermediate layer consisting of 1.2 g / m ² of gelatin.

Layer 5: 1.4 g / m ² gelatin, 0.26 g / m ² red-sensitive silver halide gelatin emulsion (silver halide composition and average grain size are shown in Table 1), 0.20 g / m ² dioctyl. 0.45 g / m ² cyan coupler (C-1) dissolved in phthalate
A red-sensitive silver halide emulsion layer containing.

Layer 6 ... Protective layer containing 0.50 g / m ² of gelatin.

The silver halide of each of the blue-sensitive silver halide emulsion layer, the green-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer was used in which the color was increased by a general sensitizing dye.

(Y-1) (M-1) (C-1) (AI-1) (AI-2) As a hardener, 0.02 g per 1 g of gelatin was added to each of 2,4-dichloro-6-hydroxy-S-triazine sodium layers 2, 4 and 6 and the following color developing solution was added after drying. The gelatin film swelling rate T1 / 2 was measured at 30 ° C. for about 7 seconds. The measurement was performed using a Lebenzone type swelling meter.

Each of the photosensitive material sample Nos. 1 to 25 shown in Table 1 was exposed through an optical wedge and then processed in the next step.

Processing step (38 ° C) Color development 120 seconds Bleaching fixing 60 seconds Washing with water 60 seconds Drying 60 to 80 ° C 120 seconds The composition of each processing solution is as follows.

[Color developer] Pure water 800 m Benzyl alcohol 15 m Hydroxyamine sulfate 2.0 g Potassium bromide 0.6 g Sodium chloride 1.0 g Potassium sulfite 2,0 g Triethanolamine 2.0 g Color developing agent (as shown in Table 1) 0.023 mol 1-hydroxy Ethylidene-1,1-diphosphonic acid (60% aqueous solution) 1.5m Magnesium chloride 0.3g Potassium carbonate 32g Kaycoll-PK-Conc (fluorescent whitening agent, manufactured by Shin Nisso Kako Co., Ltd.) 2m Pure Add water to make 1 and adjust the pH to 10.1 with 20% potassium hydroxide or 10% dilute sulfuric acid.

[Bleach-fixing solution] Pure water 550 m Ethylenediaminetetraacetic acid iron (III) ammonium salt 65 g Ammonium thiosulfate (70% aqueous solution) 85 g Sodium hydrogen sulfite 10 g Sodium metabisulfite 2 g Ethylenediaminetetraacetic acid-2 sodium 20 g Pure water was added to 1 and PH with aqueous ammonia or diluted sulfuric acid
Adjust to 7.0.

Separately, the concentration of potassium bromide in the color developer is 0.6 g /
Each of the same sample Nos. 1 to 25 as described above was developed using the color developers which were different only in the amounts of 1.5 g / and 3.5 g /.

Sensitometry was performed on each of the obtained samples by a conventional method. When the concentration of potassium bromide was 0.6 g / each sample, the concentration in the exposed area around 1.0 was set to 100, and the movement of the concentration when the concentration of potassium bromide was varied is shown in Table 1. Only the cyan density is shown in Table 1 as the ratio of color density.

Color developing agent for comparison [CD-3] [CD-6] As is clear from the results of Table 1, as compared with Samples No. 1 to No. 12 in which the silver halide is not substantially silver chlorobromide,
Samples NO.13 to NO.24 in the case of substantially silver chlorobromide, wherein the color developing agent is the exemplified compound (1) of the present invention or
In the case of (2), the bromide ion concentration in the color developer is
It can be seen that there is little change in the color density even when it changes to 0.6 g /, 1.5 g /, and 3.5 g /, indicating high processing stability. On the other hand, the conventionally known color developing agent CD-3
Or, in the case of CD-6, regardless of the composition of the silver halide, it can be seen that there is a drawback that the color density is lowered in accordance with the increase of the bromide ion concentration in the color developer in any case. . In addition, since Table 1 shows that the amount of replenishment was reduced as the bromide ion concentration was increased, it is shown that the amount of replenishment can be remarkably reduced in the treatment of the present invention.

Example 2 Using the silver halide photographic light-sensitive material sample No. 19 of Example 1, the same processing solution as in Example 1 was used to perform exposure and development in the same manner. The color developing solution was prepared by changing the color developing agent as shown in Table 2 and subjected to processing. The color development time was changed as shown in Table 2. The treatment temperature was 38 ° C.

The obtained sample was stored under irradiation with xenon lap and the change in cyan density was measured. That is, the initial concentration of the sample when CD-3 was used as the color developing agent at each processing time was 1.0
Table 2 shows the decrease in density in the same density range of the sample treated with the other color developing solution when the deterioration was about 0.3. At this time, the yellow stain density of the unexposed portion of the same sample was measured and is also shown in Table 2.

As is clear from the results in Table 2, when the color developing solution used CD-3 or CD-6 as the color developing agent, a large difference was observed in the brownness ratio regardless of the number of seconds of the color developing time. Absent. It can be seen that the brown color of CD-6 is larger than that of CD-3. This also applies to the yellow stain density (Dmin) of the unexposed area.

On the other hand, in the case of the color developing agent compound (1) or (2) of the present invention, when the color development processing time is 180 seconds or more, a large brown color is obtained and storage stability is remarkably low. This also applies to the yellow stain density (Dmin) of the unexposed area.

However, it can be seen that when the color development time is 150 seconds or less, the storage stability is drastically improved, and a more preferable result is obtained as compared with the case where the above CD-3 is used. This is surprising from the fact that the structure of the color-forming dye has conventionally been closely related to the stability of the dye, and it is predicted that the residual amount of the color-developing agent in the film is also greatly related. It

Example 3 Samples No. 3 and No. 19 of Example 1 were used, and the silver coating amounts of the blue, green and red sensitive emulsion layers were changed to those of Example 1.
Samples with various amounts of hardener added were prepared using the same amount of silver halide. The dried sample was measured for the film swelling rate T1 / 2 with a Lebenzone swelling meter using the color developing solution (processing temperature: 30 ° C.). Membrane swelling speed T1 / 2 is 2 seconds, 5 seconds, 10 seconds, 15 seconds, 30 seconds, 40 seconds, 60
Second, 90 seconds and 120 seconds samples were selected and used in the experiment. This sample was exposed to light in the same manner as in Example 1 and treated with the same treatment liquid as in Example 1. Table 3 shows the processing time required for the maximum density to be 80 when the maximum density of cyan when color development was performed at 38 ° C. for 10 minutes was 100. This result shows the rapidity of the development completion point.

As is clear from the results in Table 3, when the silver halide is silver chlorobromide, the color developing agent is the present invention, and when the film swelling speed T1 / 2 is 30 seconds or less, the development is completed very quickly ( It shows that the rapid development processing is possible. On the other hand, even with the color developing agent of the present invention, when the film swelling speed T1 / 2 is 40 seconds or more, the development completion (arrival) time becomes drastically long, and when the color developing agent is out of the present invention, Even if the film swelling speed T1 / 2 was extremely low, a fast development completion (arrival) time could not be obtained.

On the other hand, when the silver halide is substantially silver iodobromide, even if the color developing agent is that of the present invention, fast development completion (reaching) is achieved regardless of the length of the film swelling speed T1 / 2.
You will find that you do not have the time.

Example 4 Using the silver halide photographic light-sensitive materials of Samples No. 3 and No. 20 of Example 1, the red, green and red-sensitive emulsion layers had the same silver amount, and the total silver amount was 0.4 g / m ² , 0.75 g / m ² , 1.0 g /
Samples were prepared by coating so as to have m ² , 2 g / m ² , 3 g / m ² , 5 g / m ² , and 7 g / m ² . Membrane swelling speed of each sample T1 / 2
Was 7 seconds. The amount of the coupler used in Example 1 was 1.0 g / m ^2.
In the case of, the others were created by changing the silver amount ratio. The processing solution used was the same as in Examples 1, 2, and 3 except that the color developing agent was changed.

The bromide ion concentration was 1.5 g / potassium bromide.
The maximum density when the color developing solution was color-developed at 38 ° C. for 10 minutes was set to 100, and the processing time required to reach the maximum density of 80 was measured and shown in Table 4. As in Example 3, the development completion time is shown.

As is clear from the results in Table 4, even in the process of the present invention, the development completion time tends to increase sharply as the total silver amount increases, but the development completion time is significantly shorter than that in the comparative process. I understand.

Example 5 An experiment was conducted in the same manner as in Example 1 except that the developing agent in the color developer used in Example 1 was changed to the one described in Table A below. As the color paper used in the experiment, the sample No. 23 of Example 1 was used. The results are summarized in Table 5
Shown in.

From the above results, it is understood that the color developing agent of the present invention gives stable color development without being greatly affected by the dye concentration even if the concentration of prom ion in the developer is increased.
