Description

TECHNICAL FIELD The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material excellent in color reproducibility.

BACKGROUND OF THE INVENTION In color photography using a silver halide color photographic light-sensitive material, color reproduction is generally performed by a subtractive color method. That is, in a general silver halide color photographic light-sensitive material, a yellow dye-forming coupler (hereinafter simply referred to as "yellow coupler") is included in the blue light-sensitive emulsion layer.
However, a magenta dye-forming coupler (hereinafter simply referred to as "magenta coupler") is included in the green light-sensitive emulsion layer, and a cyan dye-forming coupler (hereinafter simply referred to as "cyan coupler") in the red light-sensitive emulsion layer. In the color development processing after imagewise exposure, the oxidation product of the color developing agent generated by the development of the photosensitive silver halide and the dye-forming coupler undergo a coupling reaction, and yellow, magenta, and cyan are respectively produced. To form a dye image, whereby color reproduction is performed.

The quality of the color reproducibility is one of the most important performances that influence the quality in color photography. Therefore, since the invention of the color photography method was invented, much research has been conducted to date to improve color reproducibility.

Although there are many factors that affect the color reproducibility, a particularly important factor among them is the spectral absorption property of the color forming dye.

In principle, the spectral absorption characteristics of the color forming dye can be arbitrarily selected to some extent by changing the chemical structure of the color forming dye. come. For this reason, although many compounds have been studied so far, it is the actual situation that a sufficiently satisfactory compound has not been obtained yet.

To be specific, the spectral absorption characteristics of the color-developing dye that are preferable for color reproduction are that the wavelength giving the maximum spectral absorption in the visible region (hereinafter referred to as "main absorption") and the shape of the main absorption peak are appropriate. In addition, there is little extra absorption (hereinafter referred to as “sub-absorption”) other than main absorption. First,
Regarding the main absorption, it is generally known that it can be improved to a considerable extent by selecting a substituent of the coupler or a high boiling point organic solvent of the coupler, and even under the present circumstances, it is said that almost appropriate ones are selected. You can say However, regarding the side absorption, since the side absorption particularly in the blue region of the magenta and cyan dyes has a serious adverse effect on the color reproducibility, the masking method using a colored coupler and the method using the inter-image effect are generally used in the art. And so on. However, these methods are not always available. For example, the masking method using a colored coupler can be used for an intermediate image such as a color negative film, but cannot be used for a final image such as a color reversal film or a color photographic paper. Therefore, there is a demand for the development of a coupler that gives a color-forming dye with little side absorption.

Compounds such as azole compounds described in 0-57838 and 60-168143, and indazolone compounds described in US Pat. No. 2,673,801 are known.

However, many of the above-mentioned compounds have drawbacks such as insufficient color developability, generation of other colored products in the development processing step, and color-developing dye being unstable to light and heat. , Hardly practically used. In this
It has relatively good performance for azoles,
It is known that it is a very preferable coupler in terms of color reproduction because it has a small amount of side absorption and a sharp main absorption shape.

Phenol-based and naphthol-based compounds are generally used as the cyan coupler, but as a coupler that gives a color-forming dye having a particularly preferable spectral absorption property in color reproduction, U.S. Pat.No. 2,895,826, JP-A-50- 112038

2,5-diacylaminophenol type cyan couplers described in 9352, 59-146050, 59-166956 and the like are known.

Therefore, by applying the azole-based magenta coupler and / or the 2,5-diacylaminophenol-based cyan coupler to a light-sensitive material to be a final image, such as a color reversal film and a color photographic paper, excellent color reproducibility is obtained. It is easily imagined that color photographic images will be obtained.

However, simply using the azole-based magenta coupler and / or the 2,5-diacylaminophenol-based cyan coupler (alone or in combination),
Actually obtained color photographic images (for example, color prints) were not always satisfactory. That is, for example, in the case where a color photographic paper containing the above magenta coupler and the above cyan coupler is evaluated for color gamut under a constant lightness condition by the method described in JP-A-59-100440,
Clearly, the color reproduction range is enlarged, but when printing a negative that shot an actual scene, for example, even if it is very good at reproducing a person's skin color or a specific color, the highlight part As a result, there are problems such as color balance deviations in shadow areas and shadows, and some colors are reproduced as undesired colors. As a result, the overall quality of color photographs was as good as initially expected. It turned out not to be a thing.

In some cases, it may be possible to obtain prototypes that appear to have favorable color reproducibility even in actual color photographs, but in most cases, under certain special conditions (for example, specific development processing). , A specific exposure condition, a specific viewing condition, etc.), and it does not have stable and high quality under a wide variety of handling conditions required as a product.

As a result of extensive studies to solve this problem, as a result, a silver halide containing the azole-based magenta coupler and the 2,5-diacylaminophenol-based cyan coupler and containing a yellow dye-forming coupler was used. When the emulsion layer, the silver halide emulsion layer containing the magenta coupler and the silver halide emulsion layer containing the cyan coupler are each monochromatically developed, the ratio of γ values is set to a specific value, which is particularly excellent. It was found that high color reproducibility was obtained, and the present invention was completed.

[How to obtain γ value] The developed sample satisfies the geometric conditions for reflection density measurement specified in JIS7612-1982, and the maximum transmission wavelengths for cyan, magenta and yellow are measured respectively. The reaction concentration is measured using a densitometer having an interference filter of 644 nm, 546 nm, and 436 nm (half-widths are all 18 nm or less), and the γ value is calculated by the following formula.

Here, when the reaction density of the unexposed portion is represented by D _min , E ₁ and E ₂ represent the exposure amounts required to give the reflection densities of D _min +0.5 and D _min +1.8, respectively.

Cyan γ, magenta γ and yellow γ are defined as follows.

Cyan γ: γ value obtained by measuring the reflection density of a sample in which a silver halide emulsion layer containing a cyan coupler represented by the general formula [III] mainly develops color and measuring the reflection density with an interference filter of 644 nm of the densitometer.

Magenta γ: The γ value obtained by measuring the reflection density of a sample in which a silver halide emulsion layer containing a magenta coupler represented by the general formula [II] mainly develops color and measuring the reflection density with an interference filter of 546 nm of the densitometer.

Yellow γ: The silver halide emulsion layer containing the yellow coupler represented by the general formula [I] mainly developed color. The γ value obtained by measuring the reflection density of the sample with the 436 nm interference filter of the densitometer.

Here, the term “mainly coloring” used in the definitions of cyan γ, magenta γ and yellow γ will be described. As an example, consider a silver halide color photographic light-sensitive material having the following layer structure.

Consider, for example, a case where the photosensitive material is subjected to monochromatic exposure with red light and development processing by the above method. In this case, ideally, only the red-sensitive emulsion of the third layer should be exposed to light, and only the cyan coupler of the third layer should develop color, but in reality, the spectral transmission characteristics of the filter for monochromatic exposure, Due to the spectral sensitivity characteristics of the silver halide emulsion, the first layer blue-sensitive emulsion and the second layer green-sensitive emulsion are also sensitized,
Correspondingly, yellow and magenta couplers can also be developed. Furthermore, when the red-sensitive emulsion of the third layer is exposed to light and color-developed, a part of the oxidant of the color-developing agent that reacts with the cyan coupler to develop color diffuses into the second and first layers. Thus, the magenta coupler and the yellow coupler can be developed, although only slightly. For the above reasons, the couplers of the second layer and the third layer can also partially develop color upon exposure to monochromatic red light. For the same reason, green light and
Even when monochromatic exposure with blue light is performed, the cyan coupler in the third layer can develop color. In the present invention, the term "predominantly colored" is used to distinguish these cases. Therefore, taking the above-mentioned photosensitive material as an example, the following relationship is established.

Red light monochromatic exposure → Silver halide emulsion layer containing cyan coupler is mainly colored green light monochromatic exposure → Silver halide emulsion layer containing magenta coupler is mainly colored blue light monochromatic exposure → Silver halide emulsion containing yellow coupler Layer is mainly color-developed. For the technique of using a specific cyan coupler, a specific magenta coupler and a specific yellow coupler which are partially related to the present invention, for example, JP-A-60-222852 and 60-22.
Although described in No. 9029, etc., all are only descriptions regarding color balance at the time of fading of a dye image and hue of a single dye, and a description suggesting a color reproducibility improving technique by the specific γ value balance of the present invention. There is no.

Next, the relationship between the balance of γ values and color reproducibility will be described.
Since the balance of the γ value is a factor that determines the color balance of the photographic image, it is needless to say that an appropriate balance of the γ value is necessary for reproduction of neutral colors. Therefore, in principle, a good neutral color reproduction can be obtained by properly selecting a combination of γ values of cyan, magenta and yellow.

However, the selection of this preferable combination of γ values means “in principle possible”, and it takes a lot of labor to find an actually preferable combination, for example, by trial and error. In addition, even if, fortunately, one condition that is quite preferable is obtained by chance, there is a difference in the market under that condition, such as a difference in development processing level (if the development processing level is different, the γ value of the photosensitive material is different. It is generally known that and / or its balance changes.) Even when considering, there is no guarantee that high quality can be maintained. In this way, it is theoretically possible but not easy to experimentally find the optimum combination of γ values.

Therefore, according to the present invention, the cyan coupler, the magenta coupler, and the yellow coupler according to the present invention are selected, and the γ value of the photosensitive silver halide emulsion layer containing each coupler is independently controlled. However, since a silver halide color photographic light-sensitive material having excellent color reproducibility can be obtained by forming a multilayer structure so that the γ value ratio of the present invention is obtained, the merit is very large.

Further, the silver halide color photographic light-sensitive material according to the present invention is excellent not only in reproducing neutral colors but also in color reproducibility of a single color. One of the reasons for this is that, as described above, a coupler that is preferable for color reproduction is used. However, when a prototype is actually made based on the present invention, it is far more than expected from the effect of the coupler alone. It was found that it has excellent monochromatic color reproducibility. This unexpected effect is
Presumably, this is caused by the combination of the couplers of the present invention and the specific value of the γ value ratio of each coupler-containing layer.

To prepare the silver halide color photographic light-sensitive material of the present invention, a gradation adjusting technique for each silver halide emulsion layer is required in order to obtain an appropriate γ value ratio. As a gradation adjustment technique, a conventionally used method can be applied, but the method described below is preferably used in the present invention.

The basic means of the preferred gradation adjusting method is adjustment by the amount of coated silver and the amount of coated coupler. Generally, the higher the coating amount of silver or coupler, the harder the tone, and the lower the amount, the softer the tone. According to this method, the overall gradation can be adjusted from the low exposure area to the high exposure area. The preferred conditions when this method is applied to the present invention are shown in the table below.

The following table shows more preferable conditions in which the effect of the present invention is more remarkable and the manufacturing cost and other characteristics are taken into consideration.

As another method of the basic means for adjusting the gradation by adjusting the amount of coated silver and the amount of coated coupler, another gradation adjusting method preferably used contains each of the yellow, magenta and cyan couplers according to the present invention. This is a method in which a plurality of types of silver halide emulsions having the same color sensitivity and different sensitivities are mixed and used for each silver halide emulsion layer. In this case, the plural kinds of silver halide emulsions may be mixed and contained in the same emulsion layer, or may be separately contained in a plurality of emulsion layers having the same color sensitivity. Further, plural kinds of silver halide emulsions having the same color sensitivity and substantially the same sensitivity and different gradations may be used in combination.

The method of adjusting the gradation by mixing a plurality of kinds of silver halide emulsions described above, when used in combination with the gradation adjusting method by adjusting the amount of coated silver and the amount of coated coupler, adjusts the amount of coated silver and the amount of coated coupler. It is possible to further widen the application range of the method only by adjusting the gradation.

In the method of adjusting the gradation by mixing a plurality of kinds of silver halide emulsions, it is preferable to use a monodisperse emulsion described in detail below because the gradation design can be surely and easily performed.

The gradation adjusting method by adjusting the coated silver amount and the coating coupler amount and the gradation adjusting method by mixing the plural kinds of silver halide emulsions are used individually or in combination and are used as a basic means of gradation adjustment. Make sure these means
In addition, the following gradation adjusting method is preferably used in the present invention as an auxiliary means for facilitating the operation.

One of the preferable gradation adjusting methods used as an auxiliary means for gradation adjustment is to use a compound represented by the following general formula [V].

General formula [V] In the formula, Z ₀ represents an atomic group necessary for forming a heterocycle.

No. 1, 1,563,019, US Pat. No. 3,457,078 and The Journal of Photografic Science 19, P83-87.

When the compound represented by the general formula [V] is used by adding it to each silver halide emulsion layer containing each of the yellow, magenta and cyan couplers according to the present invention, fog is generally reduced and gradation is reduced. In particular, the low density region becomes softer. When the above compound is used by adding it to an adjacent layer such as an intermediate layer adjacent to each silver halide emulsion layer, the softening function is generally reduced but the fog reducing function is maintained. Therefore, for example, in the case where the above-mentioned silver halide emulsion layer and the above-mentioned compound are added in an amount necessary for suppressing fog to make the tone excessively soft, the fog is maintained at an appropriate level and the desired gradation is obtained. The amount of each added is adjusted and used for an emulsion layer and its adjacent layer.

By using the compound represented by the general formula [V], it is possible to arbitrarily control particularly low-density gradation while maintaining the fog at an appropriate level as described above.

The compound represented by the general formula [V] is added to each silver halide emulsion layer containing each of the yellow, magenta and cyan couplers according to the present invention and / or its adjacent layer, and the addition amount thereof is effective. There is no particular limitation as long as the amount appears, but it is usually 5 as the total amount added on the support.

For the purpose of obtaining a silver halide color photographic light-sensitive material, it is preferable to use the yellow, magenta and cyan couplers of the present invention in combination with a monodisperse emulsion.

Specific Examples of the Invention Hereinafter, the present invention will be specifically described with reference to Examples, but the embodiments of the present invention are not limited thereto.

Example-1 Silver halide color photographic light-sensitive material samples 1 to 8 having the constitution shown in Table 1 below were prepared by a conventional method. However, for the third layer, in order to control the γ value ratio, the coating silver amount and coating coupler amount were set as shown in Table 2 below.

[How to obtain γ value] The samples after development satisfy the geometric conditions for reflection density measurement specified in JIS7612-1982, and have the maximum transmission wavelengths for measuring the reflection densities of cyan, magenta and yellow, respectively. The reaction concentration is measured using a densitometer having 644 nm, 546 nm, and 436 nm interference filters (half-widths are all 18 nm or less), and the γ value is calculated by the following formula.

Here, when the reaction density of the unexposed portion is represented by D _min , E ₁ and E ₂ represent the exposure amounts required to give the reflection densities of D _min +0.5 and D _min +1.8, respectively.

Cyan γ, magenta γ and yellow γ are defined as follows.

Yellow γ: γ value obtained by measuring the reflection density of a sample in which a silver halide emulsion layer containing a yellow coupler represented by the general formula [I] is mainly used for color development and measuring the reflection density with a 436 nm interference filter of the densitometer.

[Evaluation method of color reproducibility] 5R, 5YR among standard color chips made in conformity with JIS Z-8721,
This example is performed using a color negative film (using Sakura Color SR-100 and Konica FS-1) obtained by shooting 10 color patches of 5Y, 5GY, 5G, 5BG, 5B, 5PB, 5P and 5RP under sunlight. For the sample prepared in, the color correction filter was adjusted so that a patch with an achromatic color patch V value (representing lightness) of 40 was reproduced almost neutral, and printing was performed.
In the present invention, a development process similar to that specified in determining the γ value was performed to prepare a sample for evaluating color reproducibility.

Next, for the sample for color reproducibility evaluation, the color tone of the patch with the highest chroma at each lightness was measured for each color using a Hitachi Model 607 color analyzer, and from the measured value, it was specified in JIS Z-8729. The L ^* u'v 'value was obtained by the above method, and the u'v' value of the patch having an L ^* value of about 40 was plotted on the chromaticity diagram.

Next, on the chromaticity diagram, the area of the area surrounded by the above-mentioned plotted points (points adjacent to the hue color are connected by a straight line) was obtained, and this area was used as the color reproduction area, and the color reproducibility was evaluated by its width.
In this case, the larger the color reproduction range, the better the color reproducibility.

From Table-2, by adjusting the coating silver amount and the coating coupler amount, the ratio Y / C and M / C of the γ values were set within the ranges specified in the present invention, whereby the color reproducibility was improved. You can see that

Example-2 Samples 9 to 14 were prepared by changing the first layer and the third layer in Table-1 of Example-1 as follows.

[First layer] Gelatin (2.0 g / m ² ) Silver chlorobromide emulsion [mixture of the following two types of emulsion] EMB-1 [AgBr 90 mol%, 0.95 μm] EMB-2 [AgBr 90 mol%, 0.70 μm] ( The above emulsions were mixed so that the total coated silver amount was 0.35 g / m ² and the ratio thereof was the value shown in Table 3 below.) Yellow coupler Y-58 (1.2 × 10 ^-3 mol / m 2) ² ) Compound 4 of general formula [VI] (0.02 g / m ² ) High boiling point organic solvent S-6 (0.3 g / m ² ) [Third layer] Gelatin silver chlorobromide emulsion [70 mol% AgBr content] Average particle size 0.40 μm (0.18 g / m ² ) Magenta coupler 54 (1 × 10 ^-3 mol / m ² ) Compound 4 of formula [VI] (0.01 g / m ² ) Compound A (0.1 g / m ² ) Compound B (0.1 g / m ² ) High-boiling point organic solvent S-2 (0.25 g / m ² ) For Samples 9 to 14 described above,
The value reproducibility was obtained and the color reproducibility was evaluated. The results are shown in Table-3.

From Table 3, by mixing silver halide emulsions having the same color sensitivity but different sensitivities and changing the mixing ratio thereof, and making the ratio of γ values within the range specified by the present invention, the color reproducibility is improved. I understand that

Example-3 Four types of monodisperse silver chlorobromide emulsions shown in Table 4 below were prepared by the double jet method in the presence of a 3% aqueous solution of inert gelatin.

When each of the above emulsions was observed with an electron microscope,
All of them were monodisperse emulsions having almost no irregular-shaped grains mixed therein and having uniform grain size and shape.

Next, of the emulsions obtained above, for EM-1 and EM-2, sodium thiosulfate and the following sensitizing dye (D-1)
And 4-hydroxy-6-methyl-1,3,3a, 7-tetrazaindene were added at the end of the chemical ripening to obtain blue-sensitive emulsions EMB-3 and EMB-4, respectively. .

Next, EM-3 was partially divided and subjected to chemical ripening using sodium thiosulfate and the following sensitizing dye (D-2). At the end of the chemical ripening, 4-hydroxy-6-methyl-1,3,3a , 7−
20 mg per mole of tetrazaindene and silver halide
The compound represented by the general formula [V] (Example No. 13) was added to obtain a green-sensitive emulsion EMG-1.

Next, EM-4 was subjected to chemical ripening with sodium lyosulfate and the sensitizing dye (D-3) shown below, and at the end of the chemical ripening, 4-hydroxy-6-methyl-1,3,3a, 7-tetra Red sensitive emulsion EMR-
Got 1.

Next, using the above four types of chemically sensitized emulsions, the following table-
A sample having the structure shown in FIG. 5 was prepared and designated as sample 15 (comparative example). However, as the blue-sensitive emulsion for the first layer, EMB-3 and EMB-4 were used in combination in order to make the gradation in the low density portion appropriate.

The sensitizing dyes (D-1), (D-2) and (D-
The structural formula of 3) is shown.

Comparative yellow coupler CY-1, used in Table-5,
Comparative magenta coupler CM-1 and UV absorber UV
The structure of -2 is shown below.

Next, in the above-mentioned sample 15, the yellow coupler, the magenta coupler, the cyan coupler and the coating silver amount for the first layer, the third layer and the fifth layer were set to the conditions shown in Table 6 below.
Comparative samples 16 to 24 and samples 25 to 27 according to the present invention were manufactured in the same manner as sample 15 except for the above. However, regarding the blue-sensitive emulsion of the first layer, when the coating silver amount was changed, the silver amount ratios of EMB-3 and EMB-4 were always constant.

The samples 15 to 27 thus obtained, by the same method as in Example-1, to determine the γ value in monochromatic exposure, the ratio of the γ value of the yellow coupler-containing layer to the γ value of the cyan coupler-containing layer (Y / C) and The ratio (M / C) of the γ value of the magenta coupler-containing layer to the γ value of the cyan coupler-containing layer was calculated and is also shown in Table-6.

Next, the color reproducibility of each of Samples 15 to 27 was evaluated in the same manner as in Example-1. The results are also shown in Table-6.

The following can be said from Table-6. That is, in contrast to the comparative sample 15 using all the yellow, magenta and cyan couplers as comparative couplers, in the comparative samples 16 to 19 using at least one of the yellow, magenta and cyan couplers as the couplers according to the present invention. Although not sufficient, the color reproducibility is improved. Further, focusing on the point of the ratio of the γ value specified in the present invention, a comparative sample satisfying the γ value
Even with 15 to 18, the color reproducibility is not sufficient, and even if each of the yellow, magenta and cyan couplers according to the present invention is used, the sample 19 which does not satisfy the γ value ratio specified in the present invention.
Similarly, at ~ 24, the color reproducibility is not sufficient. In contrast,
It can be seen that the color reproducibility is further improved in Samples 25 to 27 in which each of the yellow, magenta and cyan couplers according to the present invention is used and the γ value ratio defined in the present invention is satisfied.

From the above, the effect that the color reproducibility is improved by the present invention is additively obtained by using the cyan, magenta and yellow couplers according to the present invention together and by setting a specific γ value ratio. It turns out to be an effect.

Example 4 In order to visually confirm the effect of the present invention on an actual print, a color negative film (actual brightness and color tone which are different from each other) obtained by photographing an actual scene is used for the sample prepared in Example-3. Object was photographed using Sakura Color SR100 and Konica FS-1 and subjected to predetermined development processing) and printed, and the reproducibility of neutral color and single color was visually evaluated according to the evaluation criteria described below. It was The results are shown in Table-7.

<Evaluation Criteria> Grade Contents ◎ Very well reproduced.

 × It is a somewhat unfavorable reproduction.

When printing, Sakura Color Printer 5N-
2 was used, and a developing solution processing process CPK-18 for color paper (manufactured by Konishi Rokusha Kogyo Co., Ltd.) was used for the developing treatment.

It can be seen from Table 7 that Samples 25 to 27 according to the present invention are excellent in both color reproducibility of both neutral colors and single colors, and the effect of the present invention can be sufficiently confirmed by visual observation of prints in practical use. Recognize. That is, it can be seen that the silver halide color photographic light-sensitive material using the present invention makes it possible to obtain a color photograph in which a single color is reproduced more vividly and the neutral color balance is not lost.

Example-5 Comparative samples 28 to 30 and samples 31 to 42 of the present invention were prepared by changing the cyan, magenta and yellow couplers of the sample prepared in Example-3 as shown in Table 8 below. The amount of coated silver is appropriately adjusted so that the γ value ratio falls within the range specified in the present invention.

Next, with respect to the samples 28 to 42, the γ value was determined in the same manner as in Example-3, and the color reproducibility was evaluated. Table with the results
8 shows.

However, the structure of the comparative magenta coupler CM-2 used in Table-8 is as follows.

From Table-8, Samples 31 to 42 according to the present invention are comparative Samples 28 to 30.
It can be seen that all of them have excellent color reproducibility as compared with. Further, among the samples of the present invention, by comparing Samples 39 to 42, in the present invention, as the cyan coupler, in addition to the cyan coupler of the general formula [III], the cyan coupler of the general formula [IV] is used. It is understood that the combined use is more preferable.

Example-6 C-29 and C-36 as cyan couplers, 59 as magenta couplers, and Y-31 as yellow couplers.
And the coated silver amount is adjusted so that the γ value falls within the range specified in the present invention, and the others are sample 41 of Example-5.
Sample 43 was prepared in the same manner as in.

Next, as the green-sensitive emulsion for the third layer, the addition amount of the compound of the general formula [V] (Exemplified No. 13) at the end of the chemical ripening was reduced to 0 mg and 10 mg per mol of silver halide, respectively. E
EMG-2 and EMG-3 obtained in the same manner as MG-1 were used, and other conditions were the same as those of sample 43 to prepare samples 44 and 45, respectively.

Next, except that the compound of the general formula [V] (Exemplified No. 13) was added to the fourth layer so that the coating amount was 0.018 mg / m ² , Sample 4
Sample 46 was prepared in the same manner as 5.

Next, samples 47 and 48 were prepared in the same manner as sample 43, except that the compound of the general formula [VI] (Ex. No. 4) in the third layer was 0 mg / m ² and 0.02 g / m ² , respectively.

Then, a sample 49 is prepared in the same manner as the sample 43 except that the compound represented by the general formula [VII] (Exemplified No. 3) is further added to the third layer so that the coating amount is 0.005 g / m ^2. did.

For the samples 43 to 49 prepared above, the γ value and the color gamut were evaluated by the method described in Example-1, and the neutral color reproducibility was evaluated by the method described in Example-4. The results are shown in Table-9.

From Table-9, it can be seen that in Samples 45, 46, 48 and 49, the color reproducibility is more preferable because the auxiliary gradation adjustment technique described in this specification was used. On the other hand, the samples 44 and 47 not using the compound represented by the general formula [V], the compound represented by the general formula [VI], the compound represented by the general formula [VII], etc., are excellent in the color reproduction range. However, there is some dissatisfaction with the neutral color reproduction in the low density range.

The other seven photographic samples, Samples 43 to 49, were also tested for other photographic performances and found to be tested with an active developer (for example, one containing a reduced amount of potassium bromide in the color developer). Fog resistance and stability of dye image to light (evaluated in sunlight for 30 days) were tested.
Fog resistance in the active developer for 44, 45 and 47, storability of the dye image in the bright place for sample 48 tended to be slightly deteriorated as compared with sample 43, respectively.
There were no problems with Sample 46 and Sample 49, respectively. As described above, by appropriately using the gradation adjusting technology described in the specification, gradation design can be facilitated and not only the color reproducibility can be improved, but also the silver halide photographic photosensitive material excellent in other photographic characteristics can be obtained. It can be seen that the material is obtained.
