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 having improved color reproducibility.
The present invention relates to a silver halide color light-sensitive material having improved reproduction stability of intermediate colors such as skin colors.

[0002]

2. Description of the Related Art There are many proposals for improving the color reproducibility of silver halide color light-sensitive materials.

With respect to the spectral sensitivity distribution, there has been proposed a method of improving the reproduction of blue-violet and red-violet hues by shifting the distribution of red sensitivity to shorter wavelengths, as disclosed in JP-A-53-20926 and JP-A-59-131.
937, etc. An appropriate spectral sensitivity distribution for reducing a variation in color reproducibility due to a difference in light source at the time of photographing is disclosed in US Pat. No. 3,672,898 and the like. IIE by the optimum use of the development inhibitor releasing compound (DIR) is shown in Japanese Patent Publication No. 7-117723. The control of the direction of IIE is disclosed in US Pat. No. 4,725,529 and the like.
By combining spectral sensitivity distribution and IIE, IIE from other than the center-of-gravity sensitivity wavelength of each color-sensitive layer is disclosed in
No. 34541 and the like. Regarding the combination of the spectral sensitivity distribution and the mixture of couplers of different hues,
No. 265945, No. 3-255438, and the like.

These proposals improve the color reproducibility of a pure color and the color reproducibility of an intermediate color, and each of them has an effect of improvement, and some of them have been put to practical use. Subtle intermediate colors that could not be reproduced by conventional color photography can now be reproduced, enabling more faithful color reproduction.

However, under the present circumstances, the reproduction stability of these silver halide color light-sensitive materials is not yet sufficient. In other words, due to fluctuations in storage of the silver halide color light-sensitive material and fluctuations in development processing, especially intermediate colors may cause color misregistration.

If the IIE balance is intentionally adjusted by using a large number of DIR compounds in order to enhance the stability of reproduction of the skin color of a person, which is the most subject, it is not preferable because the reproducibility of pure colors is deteriorated. In addition, the reproduction stability of purple is also an issue.

In the present invention, the intermediate color reproduction stabilizing layer means
By virtue of the presence of the layer, the color reproducibility of the intermediate color is less likely to be affected by fluctuations in storage and fluctuations in development processing, and has the effect of stable reproduction. Such an intermediate color reproduction stabilizing layer and the idea suggesting it have never been found.

The intermediate color reproduction stabilizing layer has one surface of the IIE (inter image effect) reducing layer. The IIE reducing layer is a layer that literally reduces the IIE between the layers.
IIE between the two photosensitive layers sandwiching the E-reducing layer may be mechanically reduced during development processing, or the IIE may be apparently reduced by automatically adjusting the coloring balance of coloring dyes having different hues. . The latter is preferred in the present invention.

The intermediate color reproduction stabilizing layer or the IIE reducing layer preferably has the following specific constitution. That is, a non-photosensitive intermediate layer existing between a silver halide photosensitive layer containing a first coupler and a silver halide photosensitive layer containing a second coupler, wherein the non-photosensitive intermediate layer is a first photosensitive layer. When containing three couplers, the non-photosensitive intermediate layer can be an intermediate color reproduction stabilizing layer or an IIE reducing layer. Here, the first, second and third couplers are respectively different in hue of a color forming dye formed by coupling with an oxidized product of a color developing agent, and preferably selected from yellow, magenta and cyan couplers. To be done. It is particularly preferable that the complementary color of the subtractive color mixture of the color forming dyes of the first coupler and the second coupler is a color forming dye of the third coupler. A combination example is shown below.

First Coupler Second Coupler Third Coupler (a) Yellow Magenta Cyan (b) Magenta Cyan Yellow (c) Cyan Yellow Magenta In a photograph, human skin color is particularly important as an intermediate color, and its reproduction is reproduced. The quality of a photograph may be judged depending on its gender. Especially in the present invention, it is important to have a skin color reproduction stabilizing layer. The layer exerts its effect when the first coupler is magenta, the second coupler is cyan and therefore the third coupler is yellow (b).

More specifically, on one side of the transparent support, there are at least one red layer containing cyan coupler, green layer containing magenta coupler, blue layer containing yellow coupler and non-photosensitive layer. A silver halide color light-sensitive material having a photographic constituent layer and a non-photosensitive intermediate layer between at least one red-sensitive layer and at least one green-sensitive layer, wherein the non-photosensitive intermediate layer comprises a yellow coupler. It is achieved by a silver halide color light-sensitive material characterized by containing. Here, the non-photosensitive intermediate layer containing the yellow coupler is the skin color reproduction stabilizing layer and the IIE reducing layer. In this case, IIE is reduced not by the IIE between the red-sensitive layer and the green-sensitive layer sandwiching the non-photosensitive intermediate layer containing the yellow coupler but by the IIE between the red-sensitive layer and the blue-sensitive layer. , IIE between the green-sensitive layer and the blue-sensitive layer is apparently reduced. Originally, the present invention has a flesh color reproduction stabilizing effect by intentionally adding a yellow coupler to the non-photosensitive intermediate layer which plays a role of color separation of a magenta image and a cyan image.

On the other hand, it is important to reproduce purple as an intermediate color in a photograph, and the quality of the photograph may be judged depending on its reproducibility. In particular, in the present invention, it is important to have a purple color reproduction stabilizing layer. The layer exerts its effect when the first coupler is yellow, the second coupler is magenta and thus the third coupler is cyan (c).

More specifically, on one side of the transparent support, there are at least one red layer containing cyan coupler, green layer containing magenta coupler, blue layer containing yellow coupler and non-photosensitive layer. A silver halide color light-sensitive material having a photographic constituent layer and having a non-photosensitive intermediate layer between at least one green-sensitive layer and at least one blue-sensitive layer, wherein the non-photosensitive intermediate layer comprises a cyan coupler. It is achieved by a silver halide color light-sensitive material characterized by containing. Here, the non-photosensitive intermediate layer containing the cyan coupler is the purple color reproduction stabilizing layer and the IIE reducing layer. In this case, IIE is reduced not by the IIE between the green-sensitive layer and the blue-sensitive layer sandwiching the cyan coupler-containing non-photosensitive intermediate layer but by the IIE between the red-sensitive layer and the blue-sensitive layer. , IIE between the red-sensitive layer and the green-sensitive layer is apparently reduced. Originally,
The present invention has the effect of stabilizing purple reproduction by intentionally adding a cyan coupler to the non-photosensitive intermediate layer that plays a role of color separation between a yellow image and a magenta image.

In the present invention, as the third coupler used in the intermediate color reproduction stabilizing layer, one having a development inhibitor or its precursor at the coupling active site (DIR coupler) is not preferred. This is because if it is a DIR coupler, a development inhibitory effect occurs on the adjacent silver halide photosensitive layer, and the stability of pure color reproduction is deteriorated. Therefore, a usual 4-equivalent coupler may be used, or a 2-equivalent coupler in which the leaving group has no development inhibiting effect is more preferable. In the present invention, all known couplers satisfying this condition can be used.

In the present invention, the silver halide photosensitive layer preferably comprises two or more layers having the same color sensitivity and different sensitivities. Then, from the support side, in order from the low sensitivity-high sensitivity layer,
Alternatively, it is preferably laminated with a low sensitivity layer-a medium sensitivity layer-a high sensitivity layer.

The coating amount of the third coupler used in the non-photosensitive intermediate layer in the present invention is 0.05 to 1.0 times the coating amount added to all the photosensitive layers containing the coupler. The following is preferable. In particular, it is preferably 0.8 times or more and 2.0 times or less of the coating amount in the highest sensitivity layer among the photosensitive layers containing the coupler.

Similarly, the standard sample and the running sample in the development processing stability test were measured in the same manner, and the S _LS and S _PU values were obtained. Table 2 shows the results.

[Table 2]

As is clear from Table 2, Sample 10 of the present invention
Looking at the color shifts due to changes in storage and processing, in Nos. 2, 103 and 106, it can be seen that the change in skin color is small with respect to the change in the primary colors (yellow, magenta, cyan), and thus the S _LS value is large. Similarly, samples 104, 105 and 10 of the present invention
6 also has a large S _PU value and a small variation in purple. Further, it can be seen that the sample 106 of the present invention is excellent in that there is little variation in skin color and purple. Therefore, it is understood that the intermediate color reproduction stabilizing layer of the present invention is not easily affected by the fluctuation in storage and the fluctuation in development processing, and stably reproduces the intermediate color.

It can be seen that Comparative Samples 107, 108 and 109 do not show the effect of stabilizing the reproduction of intermediate colors because the couplers having different hues are added to the silver halide photosensitive layer.

EFFECT OF THE INVENTION The intermediate color reproduction stabilizing layer is not easily affected by changes in storage and development and can stably reproduce intermediate colors.
