Description

The present invention relates to a silver halide color photographic light-sensitive material. More specifically, the inter-image effect (interlayer effect; hereinafter referred to as IIE) is emphasized. The present invention relates to a silver halide color photographic light-sensitive material having improved color reproducibility, sharpness, graininess and storage stability under high temperature and high humidity.

In general, a silver halide color photographic light-sensitive material has three kinds of photographic silver halide emulsion layers, which are selectively spectrally sensitized to have sensitivity to blue light, green light and red light, coated on a support. ing. For example, in a silver halide photographic light-sensitive material for a color negative, a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, and a red-sensitive silver halide emulsion layer are generally coated in this order from the exposed side, A bleachable yellow filter layer is provided between the blue-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer to absorb blue light transmitted through the blue-sensitive silver halide emulsion layer. . Further, each emulsion layer is provided with another intermediate layer for various special purposes and a protective layer as the outermost layer. It is also known that each of these light-sensitive silver halide emulsion layers is provided in an arrangement different from that described above. Further, as each silver halide emulsion layer, light-sensitivity to each color light in substantially the same wavelength range is obtained. It is also known to use a photosensitive silver halide emulsion layer having two or more layers having different properties and different sensitivities. In these silver halide color photographic light-sensitive materials, the exposed silver halide grains are developed by using, for example, an aromatic primary amine type color developing agent as a color developing agent, and the generated color developing agent is oxidized. The reaction of the product with the dye-forming coupler forms a dye image. In this method, usually, in order to form a dye image of cyan, magenta and yellow, a phenol or naphthol type cyan coupler, a 5-pyrazolone type, a pyrazolinobenzimidazole type, a pyrazolotriazole type, an indazolone type or a cyano type, respectively. Acetyl magenta couplers and acylacetamide yellow couplers are used. These dye-forming couplers are contained in the light-sensitive silver halide emulsion layer or in the developing solution. INDUSTRIAL APPLICABILITY The present invention is suitable as a silver halide color photographic light-sensitive material in which a coupler is pre-diffused and contained in a silver halide emulsion layer.

[Prior Art and Problems Thereof] Open-chain ketomethylene compounds are known as yellow couplers, and α-naphthol compounds and phenol compounds are known as cyan couplers. Examples of magenta couplers include 5-pyrazolone compounds, pyrazolobenzimidazole compounds and pyrazolotriazole compounds.

Conventionally, naphthol-based couplers have been the main cyan couplers used in silver halide color photographic light-sensitive materials having higher sensitivity. This has a feature that there is little secondary absorption in the green light region in the long wavelength region of the absorption spectrum of the cyan dye formed by the coupling reaction with the oxidation product of the color developing agent, which is preferable for color reproduction.

On the other hand, in recent years, there is a strong demand for higher image quality, and it is particularly important to improve the graininess, and it is known that one of the techniques for improvement is to increase the coated silver amount. However, when the amount of coated silver is increased, in a photographic light-sensitive material using a conventional naphthol-based cyan coupler, reduction fading of a cyan dye due to a large amount of ferrous ions occurs in a bleaching process or a bleach-fixing process of developed silver, which is a serious problem. It has drawbacks.

Examples of the coupler which does not cause reduction fading of the cyan dye in the bleaching step or the bleach-fixing step include those described in JP-A-
Although a phenolic coupler having a ureido group at the 2-position described in JP-A-56-65134 is known, the maximum absorption wavelength of the dye is on the shorter wave side than that of a phenolic cyan coupler having no ureido group. have.

Therefore, as a method for improving these drawbacks, Japanese Patent Application No. 58-13
There is a technique described in Japanese Patent No. 140, and a method for forming a dye image having a preferable absorption maximum wavelength and less secondary absorption in the green portion is proposed by this improved technique.

As described above, a photographic light-sensitive material containing a phenol coupler having a ureido group at the 2-position and a compound described in the above-mentioned Japanese Patent Application No. 58-13140 in a silver halide emulsion layer does not have the above-mentioned drawbacks. , Undeveloped photosensitive material at high temperature and high humidity for a long time (eg 40 ℃, RH80%, 10
It has been found that there is a practically serious drawback that the maximum color density and the sensitivity decrease when left for a day.

Further, Japanese Patent Application No. 57-153551 discloses a method for improving these drawbacks, which is to use a specific high-boiling point organic solvent from one technical aspect. However, it is not sufficient in terms of color reproducibility and sharpness.

In recent years, the image quality of silver halide color photographic light-sensitive materials has been remarkably improved, but the color reproducibility is still insufficient.
In particular, there are many points that are not sufficient to reproduce the color saturation (chroma). This is because the spectral characteristics of the coloring dye obtained from the coupler used (there is no sufficient absorption in a specific wavelength range, or unnecessary in other wavelength ranges such as a phenolic cyan coupler having a ureido group at the 2-position). In addition to the color mixture due to the movement of the spectral sensitizing dye, the color mixture due to the oxidant of the color developing agent is considered.

One of the characteristics required for a color photographic light-sensitive material is that, when one color-sensitive layer forms a dye image, the oxidant of the color developing agent generated there causes another color-sensitive layer to develop a color. It is not cloudy, that is, it has high color purity.

Conventionally, an isolation layer (IL), which is also called an intermediate layer, is provided between different color-sensitive layers, and a scavenger of an oxidant of a color developing agent or a colorless coupler is added to the isolation layer (IL), or an isolation layer. It is known to add a diffusion inhibitor such as a sensitizing dye to (IL), for example, fine grain silver halide grains, cationic hydrophilic synthetic polymer, polymer latex and the like. However, even these methods have not yet reached the performance of exhibiting satisfactory color reproducibility.

As another method for improving color mixing, an automatic masking technique using a colored coupler is known and is commonly used in negative silver halide color photographic light-sensitive materials, but the level of color reproducibility is not satisfactory. Absent.

There are techniques for improving color reproducibility by using a DIR coupler and emphasizing IIE, but various DIR compounds are used. For example, at the time of development, a so-called DIR coupler which reacts with an oxidized product of a color developing agent to form a color dye and releases a development inhibitor, and when developed, reacts with an oxidized product of a color developing agent to release a development inhibitor. A so-called DIR substance that does not form a coloring dye, a substance that directly releases a development inhibitor by reacting with an oxidant of a color developing agent, and a release agent that indirectly releases a development inhibitor,
For example, JP-A-54-145135, JP-A-57-154234, and JP-A-58-16.
No. 2949, No. 58-205150, No. 59-195643, No. 59-2068
No. 34, No. 59-206836, No. 59-210440, No. 60-7429, etc. (hereinafter referred to as a timing DIR compound). In the present specification, those exhibiting the DIR effect are generically referred to as DIR compounds.

When these DIR compounds are used in a silver halide color light-sensitive material, a development inhibitor is released from the DIR compound during development, and an effect of inhibiting development of another silver halide emulsion layer, that is, IIE, can be obtained. In particular, it may release so-called diffusible inhibitory groups or diffusible development inhibitor precursors.
The DIR compound is effective and has been used in the recent silver halide color film, and has some effect. DIR
Since the compound has a strong IIE direction (for example, it is strong from the blue-sensitive silver halide emulsion layer to the green-sensitive silver halide emulsion layer, but weak in the opposite direction), the saturation (chroma) of a specific color is improved. Although it can be expected, it was found to be accompanied by an unfavorable effect of “shift in hue”. Further, even if it is diffusive, the addition layer has the strongest suppression effect, so that the gamma (γ) of the addition layer, the sensitivity, the color density decrease, etc. become problems, and an amount sufficient to give sufficient effect to other layers. Is difficult to use.

JP-B-55-47379 and JP-A-57-93344 disclose a technique of using a so-called diffusible DIR compound to emphasize IIE from one color-sensitive layer to another color-sensitive layer.
No. 57-56837, No. 59-131937, etc., but the present situation is that even with these technologies, insufficient color reproducibility can be expected as described above.

Therefore, the present invention improves the color reproducibility by increasing the IIE in both directions between different color-sensitive layers by the drawback of the phenolic cyan coupler having a ureido group at the 2-position, and particularly, the saturation (chroma). Improving the reproduction of is the first technical problem.

On the other hand, as described in the above-mentioned patent publications and specifications, it is known that when IIE is generated using a so-called diffusible DIR compound, the sharpness of an image is improved.

This is due to the edge effect between the layers as well as the edge effect within the added layer and the improvement in color contrast accompanying IIE.

Therefore, the present invention aims to improve the storage stability over time under high temperature and high humidity without impairing the characteristics of the phenolic cyan coupler having a ureido group at the 2-position by combining the DIR compounds by an appropriate method. Subject.

Furthermore, the present invention uses the DIR compound according to the appropriate usage to
The third technical issue is to improve the sharpness of the image by emphasizing the IE in both directions.

The cyan coupler according to the present invention is, for example, US Pat.
It can be easily synthesized by using the method described in 308 and JP-A-56-65134.

Specific preferred phenolic cyan couplers of the present invention are described below, but the present invention is not limited thereto.

(Exemplified compound) In order to incorporate the phenolic cyan coupler according to the present invention into the silver halide emulsion layer in the present invention, a conventionally known method, for example, a known high boiling solvent such as dibutyl phthalate, tricresyl phosphate and dinonylphenol is used. Each of the couplers according to the present invention is dissolved in a mixed solution of a low boiling point solvent such as butyl acetate and propionic acid, alone or in combination, and then mixed with a gelatin aqueous solution containing a surfactant, followed by high speed After emulsifying and dispersing using a rotary mixer or a colloid mill or an ultrasonic disperser, directly added to the emulsion, or after setting the emulsified dispersion, shredded, washed with water,
This may be added to the emulsion.

The addition amount of the phenolic cyan coupler according to the present invention is usually 0.005 to 5.0 mol, preferably 0.01 to 2.0 mol per mol of silver halide. The phenolic cyan couplers according to the present invention may be used alone or in combination of two or more.

Usually, when a DIR compound is used in a certain color-sensitive layer, even if the development inhibitor or its precursor (hereinafter referred to as development inhibitor including this precursor) released is diffusible, It is difficult to use a large amount of DIR compound due to a decrease in concentration, a decrease in sensitivity, etc., because a certain addition layer itself is most suppressed.

Also, when a DIR compound is used in a layer, that layer experiences a certain amount of development inhibiting power as described above by the development inhibitor of the DIR compound of its own layer. Therefore, a phenomenon occurs in which the development inhibitory effect of the development inhibitor supplied from another layer is not sufficiently exhibited. That is, in both directions between the two color-sensitive layers
When trying to cause IIE, both IIEs will either be of a lower level, or strong in one direction and significantly weaker in the other.

However, it is clear from the results of the study by the present inventors that the released development inhibitors show different development inhibiting powers in different color sensitive layers, and that the development inhibiting powers differ depending on the type of the development inhibitor. became.

For example, when the development inhibitor A and the development inhibitor B are used in the green-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer in approximately equimolar amounts, development for the green-sensitive silver halide emulsion layer is performed. When the inhibitory power is A> B, but the development inhibitory power in the red-sensitive silver halide emulsion layer is A <B, the DIR compound having the development inhibitor B in the green-sensitive silver halide emulsion layer is red-sensitive halogenated. By adding the DIR compound having the development inhibitor A to the silver emulsion layer, the self-layer-inhibiting property in each added layer is weakened and the other color-sensitive layers are greatly affected [large IIE]. It became possible to give IIE in both directions, and it became possible to greatly increase IIE in both directions.

The usage of such a DIR compound, that is, the method for determining the color-sensitive layer to which the DIR compound should be added, is based on the above example, that is, between the green-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer. It is not only effective, but also effective in other types of different color-sensitive layers. That is, for example, when the development inhibitor C and the development inhibitor D are used in equimolar amounts in the blue-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer, the development for the blue-sensitive silver halide emulsion layer is performed. Inhibitory power is C> D, but development inhibitory power in green-sensitive silver halide emulsion layers is C <D
, The development inhibitor D is added to the blue-sensitive silver halide emulsion layer.
By adding a DIR compound having a development inhibitor C to the green-sensitive silver halide emulsion layer,
It becomes possible to keep the suppression of self-layer in each additive layer weak and to have a great influence (large IIE) on other color-sensitive layers, and to greatly increase IIE in both directions. Became possible.

Further, for example, when the development inhibitor E and the development inhibitor F are used in equimolar amounts in the blue-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer, the development for the blue-sensitive silver halide emulsion layer is performed. When the inhibitory power is E <F, but the developmental inhibitory power in the red-sensitive silver halide emulsion layer is E> F, the DIR compound having the development inhibitor E in the blue-sensitive silver halide emulsion layer is red-sensitive halogenated. By adding a DIR compound having a development inhibitor F to the silver emulsion layer, the self-layer-inhibiting property in each added layer is weakened, and a large influence [large IIE] is exerted on other color-sensitive layers. IIE in both directions, which makes it possible to give
It has become possible to dramatically increase

Note that the present invention is not limited to the case where the development inhibitor is used in an equimolar manner as described above, but by increasing or decreasing the amount of use of each development inhibitor, if the above relationship can be shown, IIE in both directions is similarly set. It can be increased. For example, when the development inhibitor G and the development inhibitor H are used, the equimolar amounts of the inhibitory effect on the green-sensitive silver halide emulsion layer are G >> H and the inhibitory properties on the red-sensitive silver halide emulsion layer are G >>. In case of H,
By reducing the addition amount of the development inhibitor G (denoted as development inhibitor G '), G'> in the green-sensitive silver halide emulsion layer>
When the relationship of H and G '<H is established in the H- and red-sensitive silver halide emulsion layers, the DIR compound having H is added to the green-sensitive silver halide emulsion layer and the DIR compound having G is added in a lower (mol) amount than the former. By adding it to the red-sensitive silver halide emulsion layer, a large IIE could be obtained in both directions.
The same was true for other types of different color-sensitive layers.

Then, when the combination of the DIR compound having each suppressing group and its additive layer is reversed (for example, in the above specific example,
DIR containing development inhibitor A in green-sensitive silver halide emulsion layer
As a compound, a DIR compound having a development inhibitor B was added to the red-sensitive silver halide emulsion layer), and the self-layer suppressing effect was very strong, and IIE in both directions was extremely small. These cases are also clarified in Examples described later.

In the present invention, the usage of the DIR compound, that is, the selection of the suppressing group of the DIR compound can be carried out by the following method.

On a (transparent) support, three types of photosensitive materials having layers having the following compositions are prepared.

Sample (I): Sample having red-sensitive silver halide emulsion layer Silver iodobromide spectrally sensitized to red sensitivity (silver iodide 6 mol%, average particle size 0.48 μm) and exemplified coupler (C-7) were silver. A gelatin coating solution containing 0.08 mol per mol of silver is applied.
It was applied at 4 g / m ² .

Sample (II): Sample having green-sensitive silver halide emulsion layer Silver iodobromide spectrally sensitized to green sensitivity (silver iodide 6 mol%, average particle size 0.48 μm) and exemplified coupler (M-2) were silver. A gelatin coating solution containing 0.07 mol per mol of silver was applied.
It was applied so as to be 1 g / m ² .

Sample (III): Sample having blue-sensitive silver halide emulsion layer. Blue-sensitive spectrally sensitized silver iodobromide (silver iodide 6 mol%, average particle size 0.48 μm) and exemplified coupler (Y-4) were silver. A gelatin coating solution containing 0.34 mol per mol of the silver coating was used.
It was applied at 5 g / m ² .

In addition to the above, each layer contains a gelatin hardening agent and a surfactant.

The obtained samples (I) to (III) were exposed to white with a wedge, and the developing time was changed to 1 minute 45 seconds for (I), 2 minutes 40 seconds for (II) and 3 minutes 15 seconds for (III). Except for the above, the treatment is performed according to the treatment method of Example 1 described later. Sample (II) for developer
The amount of various development inhibitors added was changed and the amount of each development inhibitor was not added so that the development inhibitory powers were almost the same. Sensitivity * 1 (S ₀ ) of each sample (I) to (III) treated with a developer not containing a development inhibitor and sensitivity * 1 of each sample obtained by development of a developer containing a development inhibitor * 2 (S)
(ΔS) is used as a measure of the development inhibiting power of each color-sensitive layer by each development inhibitor.

* 1) The logarithm of the reciprocal of the exposure amount (E ₀ ) at the density point of fog density +0.3, that is, −logE ₀ is taken as the sensitivity S ₀ .

* 2) As in the case of * 1) above, the sensitivity S is the logarithm of the reciprocal of the exposure amount (E) at the density point of fog density +0.3, that is, -logE.

Table 1 below shows the difference in the development inhibiting power for each color-sensitive layer for several types of development inhibitors, which were conducted based on the above standard experiment.

When the DIR couplers having the development inhibitors A-1 to A-6 are used, they may be used in a combination in which the development inhibition of the added layer itself is small and the development inhibition of the other layers is large, as described above.

In order to form a preferable combination between the red-sensitive silver halide emulsion layer and the blue-sensitive silver halide emulsion layer from the difference in the development-inhibiting power of each development inhibitor exemplified in Table 1, for example, red-sensitive silver halide is used. The value of the emulsion layer (sample (I)) is standardized to the value of one compound, and the value of the blue-sensitive silver halide emulsion layer (sample (III)) is divided by the ratio at that time to obtain a value ( (See Table 2).

That is, the following combination examples and the like are listed in Table 1.

[Example of combination of development inhibitor of DIR compound added to red-sensitive silver halide emulsion layer / development inhibitor of DIR compound added to green-sensitive silver halide emulsion layer] A-1 / A-2, A-1 / A-3, A-1 / A-4, A
-1 / A-5, A-1 / A-6, A-2 / A-3, A-2 / A
-4, A-2 / A-5, A-2 / A-6, A-4 / A-
3, A-5 / A-3, A-5 / A-4, A-6 / A-3,
A-6 / A-4 etc.

Similarly, a preferable combination, in which the added layer suppression is small and the other layer suppression is large, between the green-sensitive silver halide emulsion layer and the blue-sensitive silver halide emulsion layer and between the red-sensitive silver halide emulsion layer and the blue-sensitive silver halide emulsion layer, is preferable. You can choose.

Further, in order to emphasize IIE, it is preferable that the working distance of the suppressing group is large. That is, it is preferable that the so-called diffusivity is large.

In the present invention, the diffusibility of the suppressing group can be evaluated by the following method.

Photosensitive material samples (IV) and (V) each having a layer having the following composition were prepared on a (transparent) support.

Sample (IV): Sample having a green-sensitive silver halide emulsion layer Silver iodobromide spectrally sensitized to green sensitivity (silver iodide 6 mol%, average particle size 0.48 μm) and exemplified coupler (M-2) as silver A gelatin coating solution containing 0.07 mol per mol of silver was applied.
1 g / m ² , coated so that the amount of gelatin is 3.0 g / m ² , and a protective layer thereon; chemically sensitized and spectrally sensitized silver iodobromide (silver iodide 2 mol%, A gelatin coating solution containing an average particle size of 0.08 μm) was coated so that the coating silver amount was 0.1 g / m ² and the gelatin coating amount was 0.8 g / m ² .

Sample (V): The protective layer of the above sample (IV) from which silver iodobromide was removed.

In addition to the above, each layer contains a gelatin hardening agent and a surfactant.

Samples (IV) and (V) were exposed to white using a wedge and then processed according to the processing method of Example 1 described below except that the development time was set to 2 minutes and 40 seconds. The sensitivity of the sample (V) is 60% in the developer.
(A logarithmic display, -ΔlogE = 0.22) was used in which the amount of each development inhibitor was suppressed, and the one in which the development inhibitor was not added was used.

The sensitivity of the sample (IV) when the development inhibitor is not added is S ₀ , the sensitivity of the sample (V) is S ₀ ′, the sensitivity of the sample (IV) when the development inhibitor is added is S ₁ v, If the sensitivity of the sample (V) is Sv, the desensitization of the sample (IV) ΔS ₀ = S ₀ ′ −Sv, the desensitization of the sample (V) ΔS = S ₀ −S ₁ v, the diffusivity = ΔS / ΔS ₀ Is expressed as

However, all the sensitivities were set to the logarithm (-logE) of the reciprocal of the exposure amount at the density point of fog density + 0.3.

The value obtained by this method was used as a measure of diffusivity. Table 3 illustrates the diffusivity of several development inhibitors.

As is clear from Example 1 which will be described later, those having a relatively small diffusivity (A-5: 0.34 or less) also have a small IIE, and therefore those having a diffusivity exceeding 0.34 are preferable. In the present invention, diffusivity of 0.4 or more is more preferable.

In the silver halide color light-sensitive material of the present invention, the same light-sensitive emulsion layers are each (or at least one) 3
Although it can be divided into more than two layers, it is preferable that the number of layers does not exceed 3 because of the diffusibility of the inhibitor or inhibitor precursor generated from the DIR compound of the present invention in the layer.

In recent years, a silver halide color photographic light-sensitive material having high sensitivity, high image quality and good color reproducibility has been desired, but the present invention is directed to such a high-sensitivity silver halide color photographic light-sensitive material. It is effective when applied to materials, but rather more effective.

The following are known as a layer structure for achieving high sensitivity and the like. For example, in the above-mentioned normal layer constitution of each light-sensitive silver halide emulsion layer of a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer, which are successively coated on a support, Part or all of the photosensitive silver halide emulsion layers, substantially the same color-sensitive layer,
A high-sensitivity silver halide emulsion layer (hereinafter referred to as a high-sensitivity emulsion layer) and a low-sensitivity silver halide emulsion layer (hereinafter referred to as a low-sensitivity emulsion layer) containing a diffusion-resistant coupler capable of forming substantially the same hue as each other. There is a layer structure in which the layers are separated and adjacently stacked. Hereinafter, this layer structure is referred to as a high-sensitivity forward layer structure.

On the other hand, the following technique is known as an inverse layer structure that achieves high sensitivity.

[A] First, in JP-A-51-49027, (a) each low-sensitivity emulsion layer of a red-sensitive silver halide emulsion layer and a green-sensitive silver halide emulsion layer in order from the support side (RG low-sensitivity layer unit). (B) On the RG low-sensitivity layer unit, the high-sensitivity emulsion layers (RG high-sensitivity layer unit) of the red-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer are sequentially arranged from the support side. And (c) a structure in which high sensitivity and low sensitivity emulsion layers (B high and low sensitivity layer units) of a blue-sensitive silver halide emulsion layer are applied on the RG high sensitivity layer unit as in the normal layer configuration, [B] Further, in JP-A-53-97424, in the silver halide color photographic light-sensitive material of the above-mentioned [A], the red-sensitive silver halide emulsion layer and the green of the RG low-sensitivity layer unit are described. Each of the sensitive silver halide emulsion layers is separately coated for medium sensitivity and low sensitivity. Are, [C] Further, in Japanese Patent Application No. Sho 58-52115 by the present applicant, R
GB low-sensitivity layer unit and RGB high-sensitivity layer unit are sequentially coated on a support.

The silver halide color photographic light-sensitive material of these [A], [B] and [C] constitutions (hereinafter referred to as high-sensitivity reverse layer constitution) is
At least between the high-sensitivity green-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer having a lower sensitivity than the high-sensitivity green-sensitive silver halide emulsion layer, at least a high-sensitivity red-sensitive silver halide emulsion It is an effective means for achieving the object of high sensitivity and high image quality by having layers.

The present invention is effective, or even more effective, when applied to any silver halide color photographic light-sensitive material having the above-mentioned high-sensitivity forward layer structure and high-sensitivity reverse layer structure.

As described above, in order to apply the present invention in the case where there are a plurality of the same color-sensitive layers, one of them is an object of the combination of the present invention.

When the silver halide grains are grown, the pH, pAg, etc. in the reaction vessel are controlled, and the amount of silver ions corresponding to the growth rate of the silver halide grains as described in JP-A-54-48521 is used. It is preferable to sequentially and simultaneously inject and mix halide ions with halide ions.

The silver halide grains according to the present invention are prepared as described above. A composition containing the silver halide grains is referred to herein as a silver halide emulsion.

These silver halide emulsions include active gelatin; sulfur sensitizers such as allylthiocarbamide, thiourea and cystine; sulfur sensitizers; selenium sensitizers; reduction sensitizers such as stannous salts, thiourea dioxide and polyamines. Noble metal sensitizers such as gold sensitizers, specifically potassium aurithiocyanate, potassium chloroaurate, 2-aurothio-3-methylbenzothiazolium chloride, etc. or ruthenium, palladium, platinum, rhodium, iridium, etc. Water-soluble salt sensitizers, specifically ammonium chloroparadate, potassium chloroplatinate and sodium chloroparadate (some of these act as sensitizers or antifoggants depending on the amount) Etc.) alone or in combination as appropriate (eg combination of gold sensitizer and sulfur sensitizer, gold sensitizer) It may be chemically sensitized by using a sensitizer and a selenium sensitizer together.

The silver halide emulsion according to the present invention is chemically ripened by adding a sulfur-containing compound, and before, during, or after the chemical ripening, at least one kind of nitrogen-containing heteroaryl having a hydroxytetrazaindene and a mercapto group. You may make it contain at least 1 sort (s) of a ring compound.

The silver halide used in the present invention contains a suitable sensitizing dye in an amount of 5 × 10 ^{−8 to} 3 × 10 ^{−3 with} respect to 1 mol of silver halide in order to impart photosensitivity to a desired wavelength region. Optical sensitization can be performed by adding a mole. Various kinds of sensitizing dyes can be used, and one kind or a combination of two or more kinds of sensitizing dyes can be used.

The combination with the phenolic cyan coupler according to the present invention has a large IIE and high temperature It can be seen that the storage stability with time under high humidity is excellent. Sample No. 16 is IIE,
Although the storage stability with time is excellent, the desilvering property was inferior to the sample of the present invention because a coupler other than the phenol cyan coupler according to the present invention was used.

The sample No. 18 thus prepared was modified as shown in Table 5 below to prepare samples No. 19 to No. 30.

Each layer contains a gelatin hardening agent and a surfactant.

The same processes as in Example 1 were carried out except that each of Samples No. 18 to No. 30 was given blue light, green light, red light and white light via a wedge and the color development time was 3 minutes 15 seconds. Giving,
A dye image was obtained. The results are shown in Table 6 as in Example 1.

Further, in each of Examples 1 and 2, each DIR compound was added so that each layer alone had almost the same suppressive effect on its own layer development.
From the value of the addition amount of the IR compound, it is clear that the combination of the present invention has a small self-layer development inhibitory power (a large amount can be added), and as a result, IIE between the color-sensitive layers becomes large,
