Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, it has excellent color forming properties and color reproducibility and has improved stability of finish against variations in processing liquid composition. The present invention relates to a silver halide color photographic light-sensitive material and a color image forming method using the same.

[0002]

2. Description of the Related Art The color image forming method most commonly used in silver halide color photographic light-sensitive materials is the development of an oxidized aromatic primary amine-based color by using exposed silver halide as an oxidizing agent. By reacting the main drug with the coupler, indophenol, indoaniline, indamine,
A method for forming azomethine, phenoxazine, phenazine and similar pigments. In such a method, a method of reproducing a color image by a subtractive color method is used, and generally, three methods of yellow, magenta and cyan are used.
A color image is formed by changing the amount of color dye produced. Of these, 5-pyrazolone type couplers were generally used as magenta couplers. The 5-pyrazolone-type magenta coupler has an unfavorable second absorption band near 430 nm, which causes a problem in color reproduction.
To improve color reproducibility, pyrazoloazole-based couplers having excellent absorption characteristics have been developed. Among them,
1H-pyrazolo [5,1-c] -1,2,4-triazole-based magenta couplers described in US Pat. No. 3,725,067, 1H-pyrazolo [1,5 described in JP-B-2-44051. The -b] -1,2,4-triazole magenta coupler has excellent dye absorption properties, and the 1H-pyrazolo [1,5-b] -1,2,4-triazole magenta coupler produces a color Also, it is excellent in durability and fastness of dye image. Above all, JP-A-61-65245
No. 4,882,266 and a coupler in which a branched alkyl group is introduced into a pyrazolotriazole ring are certainly improved couplers in terms of stability against processing fluctuation and image fastness. However, there was still a problem in terms of color development. Furthermore, European patents 0,5
71,959A2, 1H-pyrazolo [1,5, b] -1,2,4-triazole-based magenta couplers having a branched alkyl group at the 6-position and a phenyl group at the 2-position are colored It is an excellent coupler that is also improved in terms of properties. However, there is a problem that the color mixture for processing becomes large, in which a yellow image has a magenta taste, particularly in rapid processing.

On the other hand, as a yellow coupler, a pivaloyl type coupler and a benzoyl type coupler have been conventionally used. The pivaloyl-type coupler was excellent in terms of image fastness, but there was a problem that the activity of the coupler was low and the dye molecule produced had a small molecular extinction coefficient. Therefore, the amount of the coupler used is inevitably increased, which is a problem in terms of economy. Further, it becomes difficult to reduce the thickness of the yellow color forming layer, which is an obstacle to further speeding up of processing and low replenishment. As an attempt to increase the extinction coefficient of a dye molecule to be produced, for example, an acylacetanilide type coupler having a 3- to 5-membered cyclic acyl group is described in EP 0,447,969A1 and EP 0,482. , 552A1 proposed a malondianilide type coupler having a cyclic structure. On the other hand, many attempts to increase the activity of the coupler have been studied. Among them, one means is to improve the activity of the coupler by increasing the hydrophilicity of the coupler. For example, a coupler having an oxazolidin-2,4-dione-3-yl group or a 1,2,4-triazolidine-3,5-dione-4-yl group introduced as a leaving group is disclosed in, for example, JP-A-50-132926. Issue 6
2-206549, 63-291056 and the like. In addition, imidazolidine-2,4-dione-
An example of a coupler having a 3-yl group introduced therein is JP-A-3-126.
No. 939, No. 3-126940, No. 3-126941.
No. On the other hand, with respect to yellow couplers, attempts have been made to improve the absorption characteristics of dyes produced in order to improve color reproducibility. The above-mentioned acylacetanilide type coupler having a 3- to 5-membered cyclic acyl group and the malondianilide type coupler having a cyclic structure were excellent couplers in terms of dye absorption characteristics. As a method for improving the hue of the pivaloyl type coupler, a method of introducing a specific group such as an alkoxy group at the ortho position of the anilide ring is disclosed in, for example, JP-A-52-115219.
No. 63-123047. Also,
Attempts to improve the color developability of these couplers
For example, JP-A-3-125140 and JP-A-3-12514
No. 1, 4-77214 and the like. Increasing the hydrophilicity of the coupler is certainly effective in terms of improving the color developability, but on the other hand, interaction with the silver halide emulsion becomes large, and when the light-sensitive material is used after being stored for a long time, When treated with a treatment liquid having a changed composition, fog is generated and gradation is changed, which causes a new problem. Further, depending on the type of magenta couplers used in combination, there arises a problem of increased color mixture in processing (color mixture in which a magenta image has a yellowish tint). In particular, in order to speed up the processing, there is a serious problem when the processing temperature is raised, the concentration of the developing agent is raised, the pH of the color developing solution is raised, or the photosensitive material is thinned.

[0004]

The present invention has been made under the circumstances described above. Therefore, the first object of the present invention is to provide 1H-pyrazolo [1, which has an excellent hue.
5-b] -1,2,4-triazole type magenta coupler is used, and the color mixture due to processing is reduced to provide a light-sensitive material having excellent color reproducibility.
A second object of the present invention is to provide a silver halide color light-sensitive material capable of maintaining stable photographic characteristics even when stored for a long period of time. A third object of the present invention is to provide a silver halide color photographic light-sensitive material suitable for rapid development processing. A fourth object of the present invention is to provide a silver halide color light-sensitive material which does not impair photographic characteristics even when it is made thin.

The metal ion used in the present invention can be incorporated into the emulsion grains either before grain formation, during grain formation, or immediately after grain formation. This can be changed depending on the position of the metal ion contained in the particle.

The silver halide emulsion used in the present invention is
Usually, it is chemically and spectrally sensitized. Regarding the chemical sensitization method, chemical sensitization using a chalcogen sensitizer (specifically, sulfur sensitization represented by the addition of an unstable sulfur compound, selenium sensitization with a selenium compound, tellurium sensitization with a tellurium compound is performed. Noble metal sensitization represented by gold sensitization, reduction sensitization and the like can be used alone or in combination. As the compound used for the chemical sensitization, those described in JP-A-62-215272, page 18, lower right column to page 22, upper right column are preferably used. The effect of the constitution of the light-sensitive material of the present invention is more remarkable than when the gold-sensitized high silver chloride emulsion is used. The emulsion used in the present invention is a so-called surface latent image type emulsion in which a latent image is mainly formed on the grain surface.

The silver halide emulsion used in the present invention may contain various compounds or precursors thereof for the purpose of preventing fog during the production process of the light-sensitive material, storage or photographic processing, or stabilizing photographic performance. It can be added. Specific examples of these compounds are described in JP-A-62-2.

As described in No. 06,025, an aqueous solution or colloidal dispersion in which a surfactant coexists may be added to the emulsion. Alternatively, the emulsion may be dissolved in a solvent that is substantially immiscible with water, such as phenoxyethanol, and then dispersed in water or a hydrophilic colloid to be added to the emulsion. JP-A-53
It may be directly dispersed in a hydrophilic colloid as described in No. 102733 and No. 58-105141, and the dispersion may be added to the emulsion. The timing of addition to the emulsion is
It may be at any stage in the preparation of emulsions heretofore known to be useful. In other words, before preparing the silver halide emulsion grains, during grain formation, immediately after grain formation, before entering the washing step, before chemical sensitization, during chemical sensitization, immediately after chemical sensitization, until the emulsion is cooled and solidified. You can choose from either. Most commonly, it is carried out after the completion of chemical sensitization and before the application, but it is described in US Pat. No. 3,628,9.
No. 69 and No. 4,225,666, it is also possible to add spectral sensitization at the same time as the chemical sensitizer as described in JP-A No. 58-113928. It can be carried out prior to chemical sensitization as described, or it can be added before the completion of silver halide grain precipitation to initiate spectral sensitization. Furthermore, the spectral sensitizing dyes may be added separately as taught in U.S. Pat. Addition is also possible and can be at any time during silver halide grain formation, including the method taught in US Pat. No. 4,183,756. Of these, it is particularly preferable to add a sensitizing dye before the step of washing the emulsion with water or before the chemical sensitization.

The addition amount of these spectral sensitizing dyes may be in a wide range depending on the case, and is 0.5 × per mol of silver halide.
The range of 10 ⁻⁶ mol to 1.0 × 10 ⁻² mol is preferable. More preferably, 1.0 × 10 ⁻⁶ mol to 5.0 × 10 ⁻³
It is in the molar range. In the present invention, particularly when a sensitizing dye having a spectral sensitizing sensitivity in the red region to the infrared region is used, the compounds described in JP-A-2-157749, page 13, lower right column to page 22, lower right column are used together. It is preferable. By using these compounds, the storability of the light-sensitive material, the processing stability, and the supersensitizing effect can be specifically enhanced. Above all, it is particularly preferable to use the compounds of the general formulas (IV), (V) and (VI) in the same patent in combination. These compounds are used in an amount of 0.5 × 10 ⁻⁵ mol to 5.0 mol per mol of silver halide.
× 10 ^-2 mol, preferably 5.0 × 10 ^-5 mol to 5.0
An amount of × 10 ^-3 mol was used, and the amount was 0.
The advantageous amount is in the range of 1 to 10000 times, preferably 0.5 to 5000 times.

The light-sensitive material of the present invention can be used not only in a printing system using a general negative printer, but also in a non-linear laser with a gas laser, a light emitting diode, a semiconductor laser, a semiconductor laser or a solid laser using a semiconductor laser as an excitation light source. It is preferably used for digital scanning exposure using monochromatic high-density light such as a second harmonic generation light source (SHG) combined with an optical crystal. In order to make the system compact and inexpensive, it is preferable to use a semiconductor laser, or a second harmonic generation light source (SHG) combining a semiconductor laser or a solid-state laser with a nonlinear optical crystal.
In particular, it is preferable to use a semiconductor laser in order to design an apparatus that is compact, inexpensive, and has a long life and high stability, and it is preferable to use a semiconductor laser as at least one of the exposure light sources.

When such a scanning exposure light source is used, the spectral sensitivity maximum of the light-sensitive material of the present invention can be arbitrarily set according to the wavelength of the scanning exposure light source used. A solid-state laser using a semiconductor laser as an excitation light source or an SHG light source obtained by combining a semiconductor laser and a nonlinear optical crystal can halve the oscillation wavelength of the laser, so that blue light and green light can be obtained. Therefore, the spectral sensitivity maximum of the light-sensitive material can be provided in the normal three regions of blue, green and red. In order to use a semiconductor laser as a light source in order to make the device inexpensive, highly stable and compact, it is preferable that at least two layers have a spectral sensitivity maximum at 670 nm or more. This is because currently available inexpensive and stable III-V semiconductor lasers have emission wavelengths only in the red to infrared regions. However, at the laboratory level, II-VI group semiconductor lasers in the green and blue regions have been confirmed to oscillate, and if semiconductor laser manufacturing technology is developed, these semiconductor lasers can be used inexpensively and stably. It is fully expected. In such cases, at least two layers should be 67
The need to have a spectral sensitivity maximum above 0 nm is reduced.

In such scanning exposure, the time for which the silver halide in the light-sensitive material is exposed is the time required for exposing a certain minute area. As this minute area, the minimum unit for controlling the light quantity from each digital data is generally used and is called a pixel. Therefore, the exposure time per pixel varies depending on the size of this pixel. The size of this pixel depends on the pixel density and is in a practical range of 50 to 2000 dpi. When the exposure time is defined as the time for exposing the pixel size when the pixel density is 400 dpi, the preferable exposure time is 10 ^-4 seconds or less, more preferably 10 ^-6 seconds or less.

In the light-sensitive material according to the present invention, a hydrophilic colloid layer is used for the purpose of preventing irradiation and halation and improving safety of safe light, etc., and it is described in EP No. 0,337,490A2, No. 27-No. It is preferable to add the dyes which can be decolorized by the treatment (in particular, oxonol dyes and cyanine dyes) described on page 76. Among these water-soluble dyes, increasing the amount used may deteriorate color separation and safelight safety. As a dye that can be used without deteriorating the color separation, there are EP 0,53
9,978A1, JP-A-5-127325, and JP-A-5-127325.
The water-soluble dyes described in 127327 are preferred.

In the present invention, instead of the water-soluble dye or in combination with the water-soluble dye, a colored layer which can be decolorized by treatment is used. The color layer that can be decolorized by the treatment used is
It may be in direct contact with the emulsion layer, or may be arranged so as to be in contact with the emulsion layer via an intermediate layer containing a processing color mixing inhibitor such as gelatin or hydroquinone. This colored layer is preferably provided in the lower layer (support side) of the emulsion layer that develops a primary color of the same kind as the colored color. It is possible to install all the colored layers corresponding to each primary color individually, or to selectively install only a part of them. It is also possible to provide a colored layer that is colored corresponding to a plurality of primary color gamuts. The optical reflection density of the colored layer is in the wavelength range used for exposure (from 400 nm to 7 in normal printer exposure).
The optical density value is preferably 0.2 or more and 3.0 or less at a wavelength having the highest optical density in the visible light region of 00 nm, the wavelength of the scanning exposure light source used in the case of scanning exposure. It is more preferably 0.5 or more and 2.5 or less, and particularly preferably 0.8 or more and 2.0 or less.

A conventionally known method can be applied to form the colored layer. For example, the dyes described in JP-A-2-282244, page 3, upper right column to page 8;

As a method for dispersing a fine powder of a pigment in a solid state, for example, a method of containing a fine powder dye that is substantially water-insoluble at a pH of 6 or less but is substantially water-soluble at a pH of 8 or more is disclosed. 2-30

A method for preparing colloidal silver as a light absorber is shown in US Pat. Nos. 2,688,601 and 3,459,563. Among these methods, the method of incorporating a fine powder dye and the method of using colloidal silver are preferable.

As the binder or protective colloid that can be used in the light-sensitive material of the present invention, it is advantageous to use gelatin, but other hydrophilic colloids can be used alone or together with gelatin. Preferred gelatin has a calcium content of 800 p
It is preferable to use low calcium gelatin of pm or less, more preferably 200 ppm or less. Further, in order to prevent various molds and bacteria that propagate in the hydrophilic colloid layer and deteriorate the image, it is preferable to add a mold preventive agent as described in JP-A-63-271247.

When the light-sensitive material of the present invention is exposed to a printer, it is preferable to use the band stop filter described in US Pat. No. 4,880,726. As a result, light color mixture is removed, and color reproducibility is significantly improved. The exposed light-sensitive material can be subjected to a conventional color development process, but in the case of the color light-sensitive material of the present invention, it is preferable to perform bleach-fixing after color development for the purpose of rapid processing.
Particularly when the above high silver chloride emulsion is used, the pH of the bleach-fixing solution is preferably about 6.5 or less, more preferably about 6 or less for the purpose of promoting desilvering.

Next, samples 001 to 030 and sample 001
Each sample of A to 030A was subjected to gradation exposure with a light source that passed through a green filter, and was treated with the treatment liquid. The optical density of the treated sample was measured with green light and blue light. At the exposure amount giving a density of 1.5 when measured with green light, the density obtained when measured with blue light was determined, and this was designated as D _B ( _DG = 1.5). Next, the sample exposed to blue light is processed and measured in the same manner, and the density obtained when measured with green light is obtained at the exposure amount that gives a density of 1.5 when measured with blue light. This is D _G
(D _B = 1.5). The D _B (D _G = 1.5) value obtained for the sample 001A is subtracted from the D _B (D _G = 1.5) value obtained for the sample 001, and the difference is Δ.
It was set to D _B (D _G = 1.5). Other samples and D _G (D _B
= 1.5) value was obtained by performing the same operation.
The D _B (D _G = 1.5) and ΔD _G (D _B = 1.5) values are listed in Table-A. In general, since the color mixing during processing becomes thicker anti-color mixing layer (intermediate layer) is improved, [Delta] D _B
The smaller (D _G = 1.5) and ΔD _G (D _B = 1.5) values, the smaller the color mixture, indicating that the photosensitive material is excellent in terms of color reproducibility.

[0183]

[Table 20] (Table-A)

As can be seen from Samples 001 to 009 in Table-A, the magenta coupler M-1 of the present invention was used in combination with the comparative coupler when used in combination with the yellow coupler Y-3 or Y-21 of the present invention. Δ when
D _G (D _B = 1.5) and ΔD _B (D _G = 1.5) are simultaneously reduced, and the color mixture during processing is reduced. When the magenta coupler of the present invention is used, it is extremely excellent in color developability, light fastness and processing dependence of the sample as compared with the case of using the magenta coupler for comparison. However, when only one of the magenta coupler and the yellow coupler is replaced with the coupler of the present invention, the color mixing is deteriorated in any of the layers, and the combination of the coupler of the present invention makes it possible to obtain the magenta coupler of the present invention for the first time. By utilizing the above characteristics, it is possible to further realize excellent color reproducibility.

Example 2 Among the samples of Example 1, one of Samples 001-026 and Reference Samples 001A-026A was stored in a refrigerator at 5 ° C. and the other was stored at 40 ° C.-80% RH for 10 days. After storage, it is exposed to blue light and green light as in Example 1,
Processed. The density of each sample was measured with blue light and green light, and the increase in the fog density (minimum color density) with respect to the refrigerated stored product at 40 ° C-80% RH was ΔD _{G min} , ΔD
_{B min} is shown in Table-B.

[0186]

[Table 21] (Table-B)

From Table-B, when the yellow coupler of the present invention is used in combination with the comparative magenta coupler ExM-1, yellow and magenta fog occur at 40 ° C. and 80% RH. It can be seen that such a problem is hardly seen when used in combination with the magenta coupler.

Example 3 The magenta coupler and yellow coupler of Sample 000 of Example 1 were replaced with the couplers shown in Table-C in equimolar amounts, and the coating amount of the second layer was changed as shown in Table-C. Other than that, Samples 101 to 120 were manufactured in exactly the same manner as Sample 000. Exposing each sample as described in Example 1,
A color mixture evaluation was carried out in the same manner as in Example 1 based on the sample which was treated and the coating amount of the second layer was increased by 1.5 times.

[0189]

[Table 22] (Table-C)

From Table-C, it can be seen that, as in Example 1, by using the yellow coupler of the present invention and the magenta coupler of the present invention in combination, the color mixture during processing can be reduced. Further, when the yellow coupler of the present invention and the magenta coupler of the present invention are used in combination, an increase in color mixing is remarkable with respect to the comparative coupler even when the coating amount of the color mixing prevention layer (second layer) is reduced. It turns out to be small. As described above, it is understood that the combination of the couplers of the present invention allows the color mixture preventing layer to be designed thinner within the practical allowable range, and is excellent in terms of speeding up the processing and economical efficiency.

Example 4 Samples 201 to 2 were carried out in the same manner as in Sample 000 except that the magenta coupler, yellow coupler and cyan coupler of Sample 000 of Example 1 were changed as shown in Table D.
08 was produced. Further, as the reference samples, Samples 201A to 208A in which the coating amount of the second layer was increased by 1.5 times were prepared. These samples were exposed to blue light, green light, and red light, respectively, and then developed as in Example 1. For each of the treated samples, ΔD _G (D _B = 1.5) and ΔD _B (D _G = 1.
5), ΔD _G (D _R = 1.5) and ΔD _R (D _G = 1.
5) was measured and described in Table-D.

[0192]

[Table 23] (Table-D)

From Table-D, it is understood that the yellow coupler and the magenta coupler of the present invention simultaneously improve the color mixture of each layer when ExC-2 having a linear alkyl group as a ballast group is used. Example 5 A sample 300 was prepared in which the composition of each layer was changed as follows with respect to the sample 000 of Example 1.

304 was produced. Further, as reference samples, Samples 301A to 304A in which the coating amount of the second layer was increased 1.5 times were prepared. After exposing these samples to blue light and green light respectively, the following three types of treatment (A, B, C)
And development processing was performed. Each process is the same as that of Example 1 except for the color developing step.

Process A: A color developer having the same composition as in Example 1 was used and the processing time was 45 seconds. Process B: The color developer of Example 1 was used to adjust the concentration of the developing agent to 1.

The processing time is changed to 30 seconds. However, the sample 300 was used as each treatment liquid, and the running treatment was performed until the replenishment amount was twice the amount of the tank liquid.

For each of the treated samples, ΔD _G (D _B = 1.5) and ΔD _B (D) were obtained by the same method as in Example 1.
_G = 1.5) values were measured and the results are shown in Table-E.

[0205]

[Table 24] (Table-E)

From Table-E, in the samples using the yellow coupler and magenta coupler of the present invention, even when the processing time was shortened by increasing the concentration of the developing agent or increasing the processing temperature, compared with the comparative sample. It can be seen that the degree of color mixing at the time of processing is small and the photosensitive material is suitable for rapid processing.

Example 6 Sample 300 of Example 5 was changed except that the coating amount of magenta coupler and gelatin in the third layer and the coating amount of magenta coupler and gelatin in the first layer were changed as shown in Table-F. Samples 401 to 425 were manufactured in exactly the same manner as the sample 300. Further, as the reference sample, Samples 401A to 425A in which the coating amount of the second layer was increased by 1.5 times were prepared. These samples were exposed to blue light and green light, respectively, and then developed in a treatment D shown below.

[0208]

[Table 25] (Table-F)

From Table-F, it can be seen that in the combination of the comparative couplers, the color mixing during the processing is significantly deteriorated by reducing the amount of gelatin in the first layer or the third layer. On the other hand, when the yellow coupler and the magenta coupler of the present invention are used, even if the amount of gelatin in the first layer or the third layer is reduced, the deterioration of the processing color mixture is extremely small. Thus, by using the coupler of the present invention in combination, it is possible to realize a thin layer of a light-sensitive material, which is economical and
It is possible to provide a light-sensitive material having high suitability for rapid processing.

2 nm, AlGaInP (oscillation wavelength, about 670 nm: Toshiba type No. TOLD9211) was used. The laser light is an apparatus capable of sequentially scanning and exposing on a color photographic paper that moves in a direction perpendicular to the scanning direction by a rotating polyhedron. Using this apparatus, the amount of light was changed to determine the relationship D-logE between the density (D) of the photosensitive material and the amount of light (E). At this time, the laser light of three wavelengths was modulated in light quantity using an external modulator to control the exposure quantity. This scanning exposure is performed at 400 dpi, and the average exposure time per pixel at this time is about 5 × 10 ^-8 seconds. The semiconductor laser uses a Peltier device to keep the temperature constant in order to suppress the fluctuation of the light quantity due to the temperature.
