Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a silver halide color light-sensitive material, and more particularly to a silver halide color light-sensitive material with improved color reproducibility in high density areas.

[Background of the invention]

In silver decagenide color photosensitive materials that form transmission images for direct observation, high density areas (transmission density of 2.60 or higher up to the maximum density) occupy a small proportion of the image, but their color reproducibility is poor. becomes a big problem. In particular, skin shading and hair color in portraits need to be faithful to the original and have natural colors.

Typically, the three primary colors that form the dye image, yellow coupler,
The characteristic curves of each layer of cyan have been designed to basically match and form colors ranging from white to gray to black in response to the amount of exposure. However, particularly in high-density areas, there is a drawback that the balance between yellow-magenta and cyan is disrupted due to fluctuations in development processing and storage over time, resulting in unnatural colors.

In response to this, we considered preventing the color balance from breaking down in high density areas by setting the maximum transmission density after development to be yellow, magenta, and cyan in descending order of density, but this alone is not sufficient. It turned out to be enough.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a silver halide color photosensitive material having excellent color reproducibility and stable high density areas.

[Structure of the invention]

The objects of the invention were achieved by the following. That is, a silver halide color photosensitive material consisting of two or more layers each having a different sensitivity, each having a red-sensitive layer containing a cyan coupler, a green-sensitive layer containing a magenta coupler, and a blue-sensitive layer containing a yellow coupler on a transparent support. , the maximum transmission density after development is 2.6 or more, yellow, magenta, and cyan in descending order of density, and blue-sensitive layer, green-sensitive layer in descending order of silver halide/gelatin weight ratio of each lowest sensitivity layer. This is a silver halide color photosensitive material characterized in that layer≧red-sensitive layer.

In the present invention, the silver halide/gelatin weight ratio of each lowest sensitivity layer is defined as the coating amount (g/m) of silver halide contained in the layer (g/m).
For convenience, in the present invention, silver halide is converted into metallic silver, and the silver coating amount (g/+a) is calculated as follows:
) divided by the gelatin coating amount (g/+++'') (hereinafter referred to as silver/gelatin ratio) is used.

In the present invention, the effect is exerted by satisfying the following order of silver/gelatin ratio in the lowest sensitivity layer: blue-sensitive layer>green-sensitive layer>red-sensitive layer. As the lowest sensitive silver/gelatin ratio,
The blue-sensitive layer is 0.30 or more and 0.80 or less, preferably 0.30 or more and 0.80 or less.
4θ or more and 0.70 or less, particularly preferably 0.45 or more and 0
．． 65 or less, and the green-sensitive layer is 0.20 or more and 0.7 or less, preferably 0.30 or more and 0.60 or less, particularly preferably 0.
35 or more and 0.55 or less, red-sensitive layer is 0.20 or more and 0.7
0 or less, particularly preferably 0.30 or more and 0.60 or less, particularly preferably 0.35 or more and 0.55 or less. The silver/gelatin ratio of the blue-sensitive layer is preferably 0.02 or more greater than that of the green-sensitive layer.

As the gelatin used in the lowest sensitivity layer of the present invention, known photographic gelatin can be used, but it is preferable to use so-called low-calcium gelatin, which has a low calcium content. Low-calcium gelatin useful in the present invention has a calcium content of 1,000 ppm.
or less, preferably 800 ppm or less, particularly preferably 6
00 ppm or less.

In the present invention, maximum transmission density means that in positive or reversal photosensitive materials, the image after development decreases as the exposure amount is reduced, but it becomes equivalent to the area that is not exposed at all. It is the concentration of time. On the other hand, in a negative-tone photosensitive material, the image density after development increases as the exposure amount is increased, but this is the density of a portion where the density does not increase even if the exposure amount is further increased.

However, in negative-tone photosensitive materials, as the exposure amount increases, the density may increase and then decrease (solarization); in this case, the maximum value is taken as the maximum density.

In the present invention, the test method for evaluating the maximum permeation density is shown below.

(1) Test conditions The test is conducted indoors at a temperature of 20±5°C and a relative humidity of 60±1O%, and the photosensitive material to be tested is left in this state for at least one hour before use.

(3) Development processing■ From exposure to development processing, the photosensitive material to be tested is maintained at a temperature of 20±5°C and a relative humidity of 60±10%.

■Development processing should be completed within 30 minutes or more and within 6 hours after exposure.

■ Development processing shall be performed as follows.

This value is determined by standardizing the value at 3560 nm of interest to 100.

After applying the same exposure to Samples 101 to 106, a development processing test was conducted in the same manner except that the first development time was changed to 8 minutes.

The transmitted density of the obtained developed sample was measured using an X-rite Co., Ltd. 7 Otodensitometer Model 310T under Status 8 conditions.

The maximum transmission density of the reference sample for samples 101-106 is yellow 3.4 to 3.7. Magenta 3.3-3,5. Cyan was within the range of 3.2 to 3.4.

Table 4 shows the differences ΔDax′ and ΔDmax” between the maximum transmission density of each sample and the reference sample obtained by forced deterioration treatment and development treatment tests.

Table 4 From the results in Table 4, it can be seen that the structure of the present invention has a higher maximum transmission density than the non-inventive structure in the forced deterioration treatment assuming long-term storage stability and the development treatment test assuming fluctuations in static image conditions. It is clear that fluctuations in balance are small and a desirable high concentration area can always be reproduced.
