Description

TECHNICAL FIELD The present invention relates to a silver halide color photographic light-sensitive material and a method for processing a silver halide color photographic light-sensitive material, and more specifically, a halogen substantially consisting of silver chloride. A silver halide color photographic light-sensitive material having a silver halide emulsion layer containing silver halide grains, capable of rapid processing, having a high maximum density and low fog, and excellent in color reproducibility. The present invention relates to a color photographic light-sensitive material and a processing method thereof.

[Prior art and its problems]

In recent years, a silver halide color photographic light-sensitive material capable of rapid processing has been desired in the art.

In other words, silver halide color photographic light-sensitive materials are run by an automatic processor provided in each laboratory. It is now required to return to users and even to return within a few hours from reception, and the development of silver halide color photographic light-sensitive materials that can be processed more rapidly is urgent. Has been.

As one of the techniques for responding to such a request for speeding up, a technique for reducing silver bromide of silver halide as described in JP-A-58-184142 and JP-B-56-18939 is known. Furthermore, a silver halide emulsion consisting essentially of silver chloride,
It is known that a large amount of rapid processing is possible. There may be several reasons for this, but the high solubility may be one of the reasons. In conventional silver halide photographic light-sensitive materials, especially color photographic paper, the blue-sensitive emulsion layer using silver halide grains with large grain size is located at the bottom, and therefore the development of the blue-sensitive emulsion layer is required. The decrease in sex was a problem. However, by using the high chloride silver halide emulsion, not only these problems are solved but also the development processing time is greatly shortened.

In particular, a silver chloride emulsion has a remarkable effect of promoting development when bromide ions which are usually used in a color developing solution are not contained.

In addition, since silver chloride absorbs almost no visible light, when used in silver halide color photographic light-sensitive materials, the blue sensitivity of green and red light-sensitive emulsions and the blue sensitivity of blue light-sensitive emulsions are higher than those of conventional emulsions. It is known that the difference between and is enlarged, color turbidity is reduced, and color reproducibility is improved.

On the other hand, most of the conventionally widely used magenta color image forming couplers were 5-pyrazolone rings. The dye formed from this 5-pyrazolone-based coupler has a yellow component due to the presence of unwanted absorption around 430 nm, so that even when a silver chloride emulsion is used, a vivid blue color cannot be sufficiently reproduced. Absent.

Therefore, when a 5-pyrazolone-based coupler is used in a silver halide emulsion consisting essentially of silver chloride, there arises a problem that the advantages of silver chloride in color reproduction as described above cannot be fully utilized. .

Further, as a magenta color image forming coupler skeleton for reducing the yellow component of the 5-pyrazolone type coupler, a pyrazolobenzimidazole skeleton described in British Patent 1,047,612, an indazolone skeleton described in U.S. Pat. The 1H-pyrazolo [5,1-c] [1,2,4] triazole skeleton described in 3,725,067 has been proposed.

When these couplers are used in a silver halide emulsion consisting essentially of silver chloride, the color is less turbid and the color reproducibility is excellent, but this type of coupler is more chromogenic than the 5-pyrazolone type magenta coupler. Tends to decrease, and particularly in a multi-layer color light-sensitive material, it tends to cause color turbidity during development on a yellow dye image.

This tendency is that a silver halide emulsion consisting essentially of silver chloride is used as the silver halide emulsion, and the color developer is
It has been found that, when the color development processing is carried out extremely rapidly without containing any bromide ion, the color developing solution becomes remarkably large when the color developing solution contains no color improving agent.

[Object of the Invention]

The present invention has been made in view of the above circumstances, and an object of the present invention is to enable rapid processing to a large extent, low fog and a high maximum density, and color turbidity during color development and spectral spectroscopicity during exposure. It is an object of the present invention to provide a silver halide color photographic light-sensitive material which prevents color turbidity and has excellent color reproducibility, and a processing method thereof.

 The present invention will be described below with reference to examples.

Example-1. Four kinds of silver chloride emulsions and silver chlorobromide emulsions described above were prepared by the neutral method simultaneous mixing method.

Each silver halide emulsion was treated with 4-hydroxy-6-methyl-1,3,3a, 7 as an emulsion stabilizer after chemical sensitization.
Tetrazaindene (STB-1) was added at 1 × 10 ^-2 mol per mol of silver halide.

The amount of the sensitizing dye added is the number of millimoles per mol of silver halide.

Then, the following layers 1 to 7 were sequentially coated (simultaneous coating) on a paper support whose both surfaces were coated with polyethylene to prepare silver halide color photographic light sensitive materials 1 to 10. (In the following examples, the addition amount is shown per 1 m ² of the light-sensitive material.) Layer 1 ... Gelatin (1.2 g) and 0.29 g (in terms of silver, the same applies hereinafter) of blue-sensitive silver chlorobromide Emulsion (E _m -1) and 0.75 g of yellow coupler (Y-1) 0.3 g of light stabilizer ST-1 and
Layer containing 0.3 g of dinonyl phthalate (DNP) in which 0.015 g of 2,5-dioctylhydroquinone (HG-1) was dissolved Layer 2 ... Dissolving gelatin (0.9 g) and 0.04 g of HQ-1 did
Layer containing 0.2 g of DOP (dioctyl phthalate) Layer 3 ... Gelatin (1.4 g), green light-sensitive silver halide emulsion shown in Table-1 and magenta coupler and light stabilizer shown in Table-1. , And 0.3 g DOP with 0.01 g HQ-1 dissolved and
Layer containing 0.06g of the following filter dye AI-I Layer 4: Gelatin (1.2g) and 0.6g of the following UV absorber
Layer containing 0.3 g of DNP in which UV-1 and 0.05 g of HQ-1 were dissolved Layer 5 ... Gelatin (1.4 g) and 0.20 g of red-sensitive silver chloride emulsion (E _m −), and 0.3 g cyan coupler C-1 and 0.2g
Cyan coupler C-2 and 0.01 g of HQ-1 were dissolved.
Layer containing 0.3 g of DOP Layer 6 ... Gelatin (1.1 g) and 0.2 g of UV-1 dissolved.
Layer containing 2 g of DOP Layer 7: Gelatin (1.0 g) and 0.05 g of 2,4-dichloro-6

Each sample was photographed with a blue subject of various densities and exposed through a color negative filter that had been color developed.
The treatment was performed according to the following treatment steps.

The compositions of the color developing solution and the bleach-fixing solution used are shown below.

Color developer Add pure water to make 1 and adjust PH to 10.08.

Bleaching fixer The reflection densities of the four blue samples obtained were measured with monochromatic lights of green and blue, and the results shown in Table 1 were obtained. In the table, “a”, “b”, “c”, and “d” indicate four types of blue subject colors. In the table, B and G indicate that the density was measured with blue and green monochromatic light, respectively.

From the results shown in Table 1, in the case where the silver halide emulsion E _m -2 having a high silver bromide composition ratio was used in the green photosensitive emulsion layer, it was confirmed that the processing was carried out in any of the processing steps [I] and [II]. It can be seen that a blue image with high blue reflection density is obtained and only blue with low saturation is reproduced.

On the other hand, when a silver halide emulsion (E _m -3) with a high silver chloride ratio is used in the green light-sensitive emulsion layer and a pyrazoloazole type magenta coupler is used, a relatively saturated blue color is reproduced. (Processing step [I]) shows that in the processing step [II], when the comparative magenta coupler other than the present invention is used, the blue saturation is lower than that in the processing step [I]. You can see that On the other hand, in the samples (8 to 10) of the present invention, it can be seen that the extremely saturated blue color is reproduced even when the rapid processing is performed in the processing step [II].

Example-2 The same procedure as in Example-1 was performed, except that the sensitizing dye used in the silver halide emulsion used in Layer 1 in Sample 8 used in Example-1 was changed as shown in Table-2. It was

However, here is a bright blue subject color (C) (D) (E)
The evaluation was performed mainly on (f).

 The results are shown in Table-2.

From the results shown in Table-2, as the blue sensitizing dyes, Samples 11 to 13 according to the present invention were treated in the same manner as in Example-1 in the treatment step [I
It can be seen that even when the rapid processing is carried out according to I], the blue reflection density is lower than the green reflection density and the blue color with high saturation is reproduced. On the other hand, when the comparative compound is used as a blue sensitizing dye, the treatment step [II]
It can be seen that the bluish chroma decreases when the treatment is performed in accordance with the procedure.

[Advantages of the Invention] As described above, according to the present invention, it is possible to perform a large amount of rapid processing.
It is possible to provide a silver halide color photographic light-sensitive material having a high maximum density and excellent color reproducibility in which color turbidity during color development and spectral turbidity during exposure are prevented.
