Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a silver halide color photographic light-sensitive material.

[0002]

2. Description of the Related Art In the field of silver halide color photographic light-sensitive materials utilizing a coupling reaction between an aromatic primary amine color developing agent and a coupler, as a magenta coupler which gives a preferable magenta dye with little unnecessary side absorption, Pyrazolotriazole couplers are conventionally known.

[0003] Recently, pyrazolotriazole couplers have been widely used in silver halide color papers, and have contributed to improving the performance thereof. On the other hand, in the field of silver halide color reversal films, which similarly form positive images and are provided for direct appreciation, color reversal films using pyrazolotriazole couplers have been commercially available, although their practical use has been considered for some time. Not realized.

One of the problems of using a pyrazolotriazole coupler in a color reversal film is that the relationship between the granularity and the sensitivity is deteriorated. Since the early days, pyrazolotriazole magenta couplers have been mainly studied for application to color papers, and therefore two-equivalent couplers having a leaving group which is released as an anion in a coupling reaction have been mainly studied. For color reversal films, the amount of dye produced per mole of silver (or image density)
When the amount is large, the sensitivity is lowered. The relationship between graininess and sensitivity is one of the most important qualities in a color reversal film using the obtained image as a print original or a print original, and the use of a 2-equivalent pyrazolotriazole coupler was difficult in this respect.

On the other hand, when the coupling position is hydrogen
When using an equivalent pyrazolotriazole, since the coupler is chemically reactive and unstable, it is a serious problem that an undesired yellow colored substance is generated over time or light irradiation after the treatment. . As a result of the study by the present inventors, it has been found that yellowing is deteriorated when a treatment is carried out, and after preservation in a dark place under a high humidity condition and then irradiation with light, is deteriorated.

[0006] Another problem when the pyrazolotriazole coupler is applied to a color reversal film is that the coloring property is insufficient when the amount of the high boiling organic solvent is small. A color reversal film is required to have high sharpness as well as granularity, and for that purpose, an image forming coupler is required to maintain good color developability even with a small amount of a high boiling organic solvent. This is because the use of an excessively high amount of the high-boiling organic solvent causes an increase in an unnecessary amount of the binder, which deteriorates the sharpness.

Thus, a silver halide color photographic light-sensitive material using a 4-equivalent pyrazolotriazole coupler,
Especially for practical use of a color reversal film, it is far from the point of yellow coloring after processing, poor color development at a low amount of high boiling organic solvent, etc., and improvement is urgently desired at present. is there.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a technique for reducing yellowing after treatment, which is a problem of 4-equivalent pyrazolotriazole couplers, and to maintain good coloring properties. While providing the technology to be achieved. Another object of the present invention is to provide a silver halide color photographic light-sensitive material excellent in color reproducibility, especially a color reversal film by introducing the technique.

Any of the known methods described in JP-A-60-220345 and the like can be used. In addition, it is also a preferable embodiment to use a chelating agent such as 1-hydroxyethylidene-1,1-diphosphonic acid or ethylenediaminetetramethylenephosphonic acid, or a magnesium or bismuth compound.

[0159] Following the washing and / or stabilizing step, drying is performed. From the viewpoint of reducing the amount of water carried into the image film, it is possible to speed up drying by absorbing water with a squeeze roller or cloth immediately after leaving the washing bath. As a means of improvement from the dryer side, as a matter of course, it is possible to speed up the drying by increasing the temperature or changing the shape of the spray nozzle to increase the drying air. Further, as described in Japanese Patent Application Laid-Open No. 3-157650, it is possible to adjust the blowing angle of the dry air to the photosensitive material,
Drying can be accelerated by the method of removing the discharged air.

[Table 7]

As can be seen from Table 7, Sample 103 using Comparative Coupler A having no dissociating group (without adding a polymer compound) was insufficient in color development. On the other hand, when the polymer compound was added, the coloring property was further reduced (sample 104). This is sample 10 using a pyrazolone coupler.
2 or Samples 105 and 10 using comparative couplers B and D
7 also had the same tendency.

When the comparative coupler C having a COOH group in the molecule was used, the coloring property was improved as compared with these. However, the bleeding of the image was poor, and the degree of yellow coloring on the white background was lower than that of the comparative coupler A. It had greatly deteriorated.
Sample 109 using the coupler of the present invention and containing no polymer compound, although the degree of deterioration of white background coloring was slightly reduced.
But it was not a satisfactory level.

On the other hand, in Samples 110 to 121 in which the coupler and the polymer compound of the present invention were used in combination, the yellowing of the white background was remarkably improved while maintaining the high color developing property. In the case of Comparative Coupler C, which is a coupler having a similar dissociating group, even when a polymer compound is used in combination (Sample 108), yellow coloring on a white background is hardly improved and coloring properties are deteriorated. Deserves special mention.

From the comparison of Samples 110 to 112, it can be seen that even if the amount of the high-boiling organic solvent is small, there is almost no effect on the coloring property, while the yellowing of the white background is further improved, giving a favorable result.
