Description

[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, a silver halide color photographic material that not only has good image graininess and color reproducibility but also has excellent development processing stability. Regarding photosensitive materials. Prior Art In recent years, the development processing method for silver halide color photographic materials (hereinafter simply referred to as "photosensitive materials") has been shifting toward high-temperature, rapid processing, so that the processing of photosensitive materials has become faster than conventional low-temperature development processing. Variability tends to increase, and techniques have therefore been developed to improve this process variability. As one of the means to improve the processing variability of the above-mentioned photosensitive materials, for example, Japanese Patent Application Laid-open Nos. 51-62723 and 52-
No. 53426 and No. 52-8802, etc., describe stabilizing the processing by accelerating development using polyethylene oxide compounds, but it is not sufficient for processing at high temperatures exceeding 35°C, for example. You can't expect any results. On the other hand, in multilayer color photosensitive materials,
It is known that processability can be improved by thinning the film by reducing the amount of silver coated, but simply reducing the amount of silver not only causes a decrease in sensitivity and deterioration of graininess, but also reduces the amount of silver coated. This is not a satisfactory method because the ratio of the amount of coupler to the amount of coupler increases and the variation in color density due to changes in silver halide development becomes more pronounced. Furthermore, the use of a 2-equivalent coupler can improve processability without causing a decrease in sensitivity. For example, JP-A No. 52-115219, No. 54-
2-equivalent yellow coupler described in No. 12338,
2-equivalent magenta couplers described in JP-A-53-123129 and JP-A-55-118034;
2-equivalent cyan couplers described in No. 105226 and No. 54-14736 are known, but satisfactory results have not yet been obtained for stabilizing processing under high-temperature rapid processing conditions. . On the other hand, according to research by the present inventors, in the case of multilayer color photosensitive materials, especially under high-temperature and rapid processing conditions, the uppermost layer has greater processing variability;
It has been found that as a result, color balance is disrupted, which has a fatal effect on color reproducibility. For example, when a blue-sensitive silver halide emulsion layer is provided as the top layer, the amount of silver used must be increased to prevent light scattering to the photosensitive layer located below and deterioration of sharpness. The coupler usage ratio is increased compared to other photosensitive layers. Furthermore, the absolute amount of coupler contained in the blue-sensitive emulsion layer is relatively large compared to other layers when high-temperature processing is taken into consideration. Therefore, in addition to the reason that it is located in the top layer, changes in the developability of the silver halide emulsion in the blue-sensitive layer increase the color density, and as a result, the balance with the color density in other layers is lost. The balance is disrupted, and this becomes a fatal flaw when processing fluctuations occur. From this point of view, there is a demand for the development of improved techniques for stabilizing development processing, particularly under high temperature conditions. Purpose of the Invention The purpose of the present invention is, firstly, to provide a silver halide color photographic light-sensitive material with excellent development processing stability, and secondly, to provide a silver halide color photographic material with excellent image graininess and color reproducibility. The purpose of the present invention is to provide a silver color photographic material.

[Table] The light-sensitive material of the present invention has a silver halide emulsion layer on a support, each containing a cyan coupler, a magenta coupler, and a yellow coupler as described in detail above. The arrangement of the emulsion layers may be arbitrary, but in order from the support side, the cyan coupler-containing silver halide emulsion layer according to the present invention, the magenta coupler-containing silver halide emulsion layer according to the present invention, and the yellow coupler-containing silver halide emulsion layer according to the present invention. A layer structure in which an emulsion layer is coated is preferred. The present invention provides a photosensitive material having the above-described layer structure, when the content of the cyan coupler, magenta coupler, and yellow coupler per unit area is in a molar ratio of 1.2 to 1.8:0.4 to 0.7. The effect of this method is remarkable. On the other hand, in conventional photographic color photosensitive materials having the above layer arrangement, the coupler content per unit area is approximately 1.2 to 1.8 for cyan coupler and 1.3 for yellow coupler to 1 for magenta coupler in terms of molar ratio. Taking this into account, it can be seen that the amount of yellow coupler used in the light-sensitive material of the present invention is significantly reduced compared to the amount of other couplers, ie, cyan coupler and magenta coupler. In order to incorporate each of the couplers according to the present invention into a light-sensitive material, the couplers are dissolved in a high-boiling organic solvent by a conventionally known method, for example, the method described in U.S. Pat. No. 2,322,027, and then applied directly to the light-sensitive material. Alternatively, the coupler and the high-boiling organic solvent may be separately dispersed into fine particles by the method described in U.S. Pat. No. 2,801,170, and then mixed and mixed into the coating solution. You may let them. In the above dispersion method, a low boiling point organic solvent may be used in addition to the high boiling point organic solvent, or as an alternative method, part or all of the high boiling point organic solvent that is immiscible in water is insoluble in water but soluble in the organic solvent. It may be replaced with a polymer of According to the present invention, the rate of reduction of yellow coupler in the present invention is approximately 2/3 of the amount of yellow coupler used in conventional photosensitive materials per unit area.
Applies to ~1/2 amount. Therefore, when using a coupler dispersion method using a high boiling point organic solvent and/or a low boiling point organic solvent as described above, the proportion of the solvent used can be reduced in accordance with the weight loss rate of the coupler. According to such a general oil protection dispersion method, the amount of gelatin binder in the emulsion layer into which the coupler is mixed and the amount of the coupler protected and dispersed are in an approximately constant ratio, and the ratio is approximately constant. . Therefore, as in the present invention, the amount of yellow coupler per unit area is reduced to 1/2 compared to the conventional amount.
If the amount is reduced by ~2/3, the amount of gelatin used can be reduced according to the amount of yellow coupler reduced. As is clear from the above, the amount of gelatin in the yellow coupler-containing layer according to the present invention can be reduced to 1/2 to 2/3 per unit area similarly to the coupler. is necessarily thinner than a normal emulsion layer. Therefore, improved photographic properties, such as improved sharpness, can also be obtained as an advantageous effect. Furthermore, according to the present invention, by using a coupler with excellent coloring efficiency as represented by the general formula [] as a yellow coupler, deterioration of coloring density due to a reduction in the amount of coupler is prevented, and the amount of coupler is This made it possible to reduce the amount of As explained in detail above, the light-sensitive material of the present invention uses the silver halide emulsion layer located farthest from the support as a blue-sensitive layer, and uses a significantly reduced amount of the yellow coupler of the present invention. Furthermore, by coating a silver halide emulsion layer containing the magenta coupler according to the present invention and a silver halide emulsion layer containing the cyan coupler according to the present invention on a support, conventional color development processing, particularly high-temperature rapid processing, can be performed. It was possible to prevent the color balance from occurring between the color-sensitive layers as seen above, and to improve color reproducibility. In the light-sensitive material of the present invention, a non-photosensitive layer such as an intermediate layer may be provided between each of the color-sensitive layers, and each color-sensitive layer may have two or more emulsion layers having different sensitivities. It may be composed of two layers or three layers. Furthermore, in addition to the couplers according to the present invention, the light-sensitive materials of the present invention include, for example, colored couplers having an azo group at the active site of the coupler, and other compounds containing oxidized forms of color developing agents for the purpose of improving graininess and interlayer effects.

The silver halide emulsion layer constituting each color-sensitive layer of the light-sensitive material of the present invention contains reducing agents or antioxidants such as sulfites (sodium sulfite, potassium sulfite, etc.), bisulfites (sodium bisulfite, potassium bisulfite, etc.). potassium, etc.), hydroxylamines (hydroxylamine, N-methylhydroxylamine, N-phenylhydroxylamine, etc.), sulfinic acids (sodium phenylsulfinate, etc.), hydrazines (N,N'-dimethylhydrazine, etc.) , reductones (ascorbic acid, etc.), aromatic hydrocarbons having one or more hydroxyl groups (P-aminophenol, alkylhydroquinone, gallic acid, catechol, pyrogallol, resorcin, 2,3-dihydroxynaphthalene, etc.), etc. can do. Furthermore, in order to further improve the light fastness of the magenta color image formed from the magenta coupler used in the present invention, P-alkoxyphenols and phenolic compounds may be added to the emulsion layer or its adjacent layer. can. The non-photosensitive layers constituting the photosensitive material of the present invention include a protective layer, an intermediate layer, a filter layer, an undercoat layer,

The above silver halide emulsion can be sensitized using a known chemical sensitizer. As the chemical sensitizer, noble metal sensitizers, sulfur sensitizers, selenium sensitizers, and reduction sensitizers can be used alone or in combination. A known binder is used as the binder for silver halide. Furthermore, the silver halide emulsion used in the present invention can be spectrally sensitized using a known sensitizing dye, if necessary. In order to prevent a decrease in sensitivity and the occurrence of fog during the manufacturing process, storage or processing of the above-mentioned silver halide photosensitive materials, 1-phenyl-5-mercaptotetrazole, 3-methylbenzothiazole, 4-hydroxy-6- Various compounds such as heterocyclic compounds such as methyl-1,3,3a,7-tetraazaindene, mercapto compounds, metal salts, etc. can be added.

In addition, for samples with different coupler contents, the amount of the DIR compound used in the comparative samples was controlled by a method well known in the art to adjust to the same gradation as the comparative samples.

[Table] Samples 1 to 10 thus obtained were subjected to edge exposure according to a conventional method, and then subjected to the following treatments.

The sensitivity, gamma and processing stability of each sample of the obtained color images were measured according to the following procedure, and the results are shown in Table 2 below.

[Table] (Sensitivity) The sensitivity of each color-sensitive layer of Sample-1 was set as 100, and the sensitivity was expressed as a relative sensitivity value. (gamma) tanθ of the characteristic curve from the point giving the density 0.3 from the minimum density. (Processing Variability) Among the compositions of the color developing solution mentioned above, 4-amino-
3-Methyl-N-ethyl-N-(β-hydroxyethyl)aniline sulfate and potassium bromide were changed to the compositions shown in Table 3 below, and otherwise the same color developer was used to determine processing variability. Measurements were made.

(β-Hydroxyethyl)aniline sulfate B: Potassium bromide The results of development using the above three types of color developing solutions CD-1, CD-2 and CD-3 are shown in Table 4 below. The gamma (γ) balance in the table is expressed as the value obtained by dividing the gamma (γ ₂ ) of the green-sensitive emulsion layer by γ ₂ of each photosensitive layer.

【table】

[Table] As is clear from the results in Table 2 above, Samples 2 to 5 according to the present invention have higher sensitivity than Comparative Sample 1, and as can be understood from Table 4, the color development It was made clear that the processing variation due to changes in the composition of the developing agent was small and good, and that the variation in the yellow coupler-containing layer was particularly small. Among them, Samples 3 to 5 showed particularly excellent processing stability, and it was also found that even when printed on color paper, the color reproducibility did not deteriorate due to changes in the processing solution and showed good color balance. On the other hand, Table 2 shows that in Sample 6, which is not of the present invention, sufficient gradation cannot be obtained because the yellow coupler content in the yellow coupler-containing layer is low. In addition, in Sample 7, a screw-type magenta coupler of the same type as the yellow coupler of the present invention was used in the magenta coupler-containing layer, but it can be seen from the results in Table 4 that processing variability is rather increased. I can do it. In addition, samples 8, 9, and 10, which have coupler molar ratios other than those of the present invention, all have insufficient gradation as shown in Table 2, or have variations in processing as shown in Table 4. It was also found that they had some drawbacks, such as being unsatisfied with their sexuality. Example 2 Regarding the color images obtained by performing the color development process described in Example-1 using Samples 1 to 10 created in Example 1, the graininess was measured as shown in the table below. The results are shown in Table 5 below.
[Image granularity (RMS)] It is expressed as a value 1000 times the standard deviation of density value fluctuations that occur when scanning with a circular microdecimator having a scanning aperture of 25 μm. Table 5 shows the RMS granularity of each coupler-containing layer at a concentration of 0.7.

[Table] As shown in the above table, sample-2 according to the present invention
It can be seen that the granularity of samples 5 to 5 is significantly improved. On the other hand, it was also found that even if the coupler content of the magenta coupler-containing layer was lowered by including a bis-type magenta coupler as in Sample 7, the granularity was not improved but rather deteriorated. . Furthermore, although the effect of improving granularity can be obtained by lowering the molar ratio of cyan coupler in the cyan coupler-containing layer, as shown in Example 1, it cannot be applied to photosensitive materials since satisfactory gradation cannot be obtained. It was also understood that there was a problem.
