Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color light-sensitive material, and more particularly to a high-sensitivity silver halide color light-sensitive material having improved storage stability and a photographic unit package.

[0002]

2. Description of the Related Art In recent years, general-purpose silver halide color light-sensitive materials have been changed from the conventional mainstream ISO-100 film to a high-sensitivity film of ISO-320 or higher. This is due to the fact that the image quality has improved in addition to the advantage of reducing shooting failures. Due to the high sensitivity, the effect of camera shake is reduced by using the high-speed shutter, the fast-moving subject can be captured, it is possible to shoot even in a dimly lit place, and the aperture can be narrowed down to focus. This makes it easier for the user to take pictures, which ultimately reduces the number of shooting failures. In addition, the image quality has been improved to the level of the conventional ISO-100, and is becoming a place where users are satisfied. Therefore, a simple system such as a photographing unit (film with a lens) has become possible and has been widely used.

However, a film of ISO-320 or higher has a large silver coating amount, which is a heavy load for a developing station that is proceeding with shortening and improving the efficiency of development processing steps, and its improvement is a problem of the industry. Has become. Further, the large silver coating amount increases the thickness of the light-sensitive material, which limits the improvement of image quality such as sharpness and the stabilization of storage characteristics.

Since high-sensitivity films of ISO-320 or higher use high-sensitivity silver halide emulsions, colloidal silver particles used in the light absorption filter layer and antihalation layer cause undesired contact fog. The colloidal silver has the drawback that it also reduces the desilvering rate in the desilvering step of the developing process. There is a proposal to use an organic dye instead of colloidal silver, but it is not effective because the decolorizing property is insufficient and unnecessary absorption remains, or it diffuses to other layers during storage and the filter effect decreases. Further, there are proposals of bleaching accelerator releasing couplers and the like for improving the desilvering rate, but they are not sufficient for practical use.

Further, in recent years, a magnetic material-containing layer has been provided on a silver halide light-sensitive material to record and read information as a magnetic recording layer for use to reflect the photographer's intention, improve the finished state of photographs, and work in a photo lab. It is being studied to prevent mistakes and improve efficiency. However, by providing the magnetic recording layer, it becomes clear that the preserving property of the sealed silver halide color light-sensitive material before development is deteriorated, and improvement thereof is desired. It was also revealed that when a photographing unit in which a silver halide color light-sensitive material was loaded in advance and ready for photographing was sealed and stored, sensitivity fluctuation and fogging occurred.

JP-A-3-123348 describes a silver halide color light-sensitive material containing a fine crystal dispersion of a dye and having a total film thickness of 18 μm or less. JP-A-3-130760 describes a silver halide color light-sensitive material containing a fine crystal dispersion of a dye and having a silver content of 12 g / m ² or less. JP-A-4-172342 describes a silver halide color light-sensitive material having a specific photographic sensitivity of 320 or more and a film thickness of 22 μm or less. Both are insufficient to solve the above problems.

Preparation of sample 115 from sample 102 The silver halide emulsions of the third, fourth, fifth, seventh, ninth, tenth, thirteenth layers of sample 101 were uniformly increased by 40% to obtain a silver coating amount of 8.50. Sample 102 was prepared by setting g / m ² and increasing the coating amount of gelatin in the third to thirteenth layers to a film thickness of 23 μm. sample
Sample 105 was prepared by removing the yellow colloidal silver in the 11th layer of Sample 101 and adding the dispersion of Comparative Dye-1 instead. However, Samples 116 to 120 were prepared in the same manner except that the composition of Sample 101 was changed to the following (1) to (3). (1) The magenta couplers M-1 and M-2 of the seventh, ninth and tenth layers are magenta couplers M-3 and M-5, respectively, and the colored magenta coupler CM-1.
Was changed to CM-2, and OIL-4 was changed to OIL-5. (2) DIR compounds D-4 and D-5 of the 12th layer
Were changed to D-6 and D-1, respectively. (3) Emulsion L was used in place of emulsion C, emulsion H was used in place of emulsion D, and emulsion J was used in place of emulsion E. Table 4 below shows specific photographic sensitivity, silver coating amount, film thickness, and filter dye in the 11th layer of each sample.

Sample 120 was prepared by removing the black colloidal silver in the first layer and adding a microcrystalline dispersion of a mixture of dyes I-1, I-4 and III-34 instead.

For each of the obtained samples, 135 standard size 2
I cut it into 4 shots and stored them in a small patrone. Another group is placed in a polyethylene cylindrical container and sealed, and the other group is loaded into the photographing unit shown in FIG. did. The inside of each sealed container was 23 ° C. and the relative humidity was 50%. Hermetically sealed items are at 50 ° C and 60% relative humidity
The sample was left for 5 days in the atmosphere to substitute for the evaluation of storage characteristics. All samples were exposed to a test pattern for specific sensitivity evaluation and storage property evaluation.
Treatment with C-41 manufactured by Eastman Kodak Co., Ltd. described in L. of Photography 1988, P.196-198 was performed. Further, a treatment in which the bleaching bath treatment time was shortened to 60% for desilvering evaluation and a treatment in which the entire treatment time was shortened to 80% for dye stain evaluation were also performed.

The desilvering property was evaluated by measuring the amount of residual silver in the saturated exposed portion by a silver atomic absorption method in a treatment in which the bleaching bath treatment time was shortened to 60%, and the residual silver amount was evaluated according to the following four grades.

A: less than 0.1 g / m ² B: 0.
1g / m ² or more and less than 0.2g / m ² C: 0.2g / m ² or more and less than 0.4g / m ² D: 0.4g / m ² or more Dye contamination is evaluated by reducing the overall processing time to 80% In the spectral absorption of the dye image between the standard processing and the standard processing, the difference ΔD in the density of the absorption wavelength of the dye used in the light-sensitive material is shown. The storage fog and the sensitivity fluctuation are shown by the increase in fog of the yellow image depending on the presence or absence of the high temperature forced deterioration test.

The results are shown in Table 5.
