Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a color photographic material, and more specifically,
This invention relates to a color photographic material with excellent hue reproducibility.

(Background of the Invention) In recent years, the image quality of silver halide multilayer color photographic materials has significantly improved.

In other words, in recent color photographic materials, there are three types of image quality.
The three major factors of graininess, sharpness, and color reproducibility are all at extremely high levels. For example, when it comes to general color photographs, it is generally believed that there are no major complaints regarding the color prints and slide photographs that users receive.

However, among the three factors mentioned above, in terms of color reproducibility in particular, although color purity has improved, the situation has not changed much with respect to colors, which have traditionally been said to be difficult to reproduce in photographs. That is, there are still many imperfections in hue reproducibility. For example, 600nm
Violet colors such as violet and blue-violet that reflect longer wavelength light, or green colors such as blue-green and yellow-green, may be reproduced as completely different colors from the actual colors, which may disappoint users. .

The major factors related to color reproducibility include spectral sensitivity distribution and glabellar effect (interimage effect).

The following is known about the interimage effect. That is, in silver halide multilayer color photographic light-sensitive materials, it is known to add a compound that couples with the oxidized form of a color developing agent to form a development inhibitor or its precursor. It is known that by inhibiting the development of other color-forming layers using a development inhibitor, an interimage effect is produced and color reproducibility is improved.

Furthermore, in color negative films, it is possible to provide an effect similar to the interimage effect by using a colored coupler in an amount greater than the amount that offsets unnecessary absorption.

However, if you use a lot of colored couplers,
As the minimum density of the film increases, the colors and
Density correction becomes very difficult to judge and often results in poor color quality in the resulting print.

Incidentally, these techniques particularly contribute to improving color purity among color reproducibility. The so-called diffusive DIR, in which the mobility of inhibitor groups and their precursors, which have been frequently used recently, is high, greatly contributes to the improvement of color purity. However, it is difficult to control the directionality of the interimage effect, and although it can achieve high color purity,
It also has the disadvantage of changing the hue (direction control of interimage effects is described in US Pat. No. 4,725,529, etc.).

On the other hand, regarding the spectral sensitivity distribution, U.S. Patent No. 3.672
, No. 898 discloses an appropriate spectral sensitivity distribution for reducing variations in color reproducibility due to differences in light sources during photographing.

However, this is not a means to improve the aforementioned poor color reproducibility.

In JP-A-61-34541, which also discloses a technology that combines spectral sensitivity distribution and interimage effect, an attempt was made to improve the colors that are difficult to reproduce with the aforementioned color film, and the results showed some effects. I think you can get it. Typical examples include not only the interimage effect from the conventional wavelength of the center of gravity of the blue-sensitive layer, green-sensitive layer, and red-sensitive layer (but also the interimage effect from the wavelength of the center of gravity of each color-sensitive layer). The idea is to put people to work.

This technique is effective to some extent in improving the hue reproducibility of specific colors, but specifically, it improves the original blue sensitivity for the expression of interimage effects.

In addition to the green-sensitive and red-sensitive photosensitive layers, an interimage effect layer and another type of photosensitive silver halide are required.
Due to an increase in the amount of silver and an increase in the number of production processes,
This method has the disadvantage of high production costs, and is not sufficiently effective.

For the above reasons, conventional silver halide color photographic materials have been insufficient in terms of hue reproduction. In particular, it was difficult to faithfully reproduce the hue of blue-green, which sometimes appeared far away from the actual color.

[Object of the Invention] An object of the present invention is to provide a color photographic material that faithfully reproduces blue-green and green hues and improves the brightness of green and yellow colors in color reproduction of an object. It is.

[Structure of the Invention] The above object of the present invention is achieved by the following silver halide color photographic light-sensitive material.

That is, at least one red-sensitive silver halide emulsion layer (hereinafter also referred to as "red-sensitive layer" as appropriate) on the support,
at least an IN green-sensitive silver halide emulsion layer (hereinafter sometimes referred to as a "green-sensitive layer"), and at least one
blue-sensitive silver halide emulsion layer (hereinafter referred to as "blue-sensitive layer" as appropriate)
In a silver halide color photographic light-sensitive material having a spectral sensitivity distribution of 415 nm to 4
70 nm, and the maximum sensitivity at the lowest density +0.1 of the spectral sensitivity distribution of the blue-sensitive layer is the lowest density at 480 nm +0.
．． 1, and reacts with the oxidized product of the color developing agent in the blue-sensitive layer to release a development-inhibiting group or its precursor, and the degree of diffusion of the development-inhibiting group or its precursor is 0. This is achieved by a silver halide color photographic light-sensitive material characterized by containing a compound having a molecular weight of .34 or more.

The present invention will be explained in detail below.

The present invention provides at least one blue-sensitive silver halide emulsion layer on a support, each containing a generally yellow coloring color coupler, a green-sensitive silver halide emulsion layer containing a generally magenta coloring color coupler, and a generally cyan coloring color coupler. This is a color photographic light-sensitive material having a red-sensitive silver halide emulsion layer containing a color coupler that develops color.

In the light-sensitive material of the present invention, the spectral sensitivity distribution of the blue-sensitive silver halide emulsion layer has a wavelength that provides the maximum sensitivity in the range of 415 to 470 nm in the spectral sensitivity distribution that provides the minimum density of the blue-sensitive layer + 0.1; 4 of the same spectral sensitivity distribution
Sensitivity at 80 nm is 50% of the maximum sensitivity of the same spectral sensitivity distribution
The following shall apply.

In the present invention, the spectral sensitivity distribution refers to the spectral sensitivity distribution of 400
Exposure is applied with spectral light at intervals of several nl11 from nrn to 700 nm, and the exposure amount that provides a constant density at each wavelength is defined as the sensitivity at each wavelength, and the sensitivity is defined as a function of wavelength.

One way to give the blue-sensitive silver halide emulsion layer a spectral sensitivity distribution in the shape according to the present invention is to spectral sensitize any silver halide with a sensitizing dye having an absorption spectrum in a desired wavelength range. or a means to obtain the desired spectral sensitivity by optimizing the halogen composition and its distribution of silver halide without using a sensitizing dye, or a means to obtain the desired spectral sensitivity by using an appropriate optical absorber in the light-sensitive material. There are means to adjust the distribution. Of course, these methods may also be used in combination.

Specific examples of sensitizing dyes used in the blue-sensitive silver halide emulsion layer of the light-sensitive material of the present invention to obtain the above-mentioned spectral sensitivity distribution are shown below, but the invention is not limited thereto.

The blue-sensitive layer of the color photosensitive material of the present invention contains a compound (hereinafter appropriately referred to as a DIR compound) capable of releasing a development-inhibiting group or a precursor of a development-inhibiting group by reacting with an oxidized form of a color developing agent, and Compounds in which the diffusivity of the inhibitor group or its precursor is 0.34 or more as determined by the evaluation method described below (hereinafter referred to as a diffusible DIR compound)
Contains.

The diffusivity of the diffusible DIR compound is set to 0 in order to increase the interimage effect from the blue-sensitive layer to the green-sensitive layer, and to prevent the interimage effect from the blue-sensitive layer to the red-sensitive layer from becoming unnecessarily large. It is preferable that it is .34 or more and less than 0.6. The diffusivity is preferably 0.40 or more and less than 0.6.

The resulting films of each sample were printed on color paper (Konica Color PC Paper Type SR) so that gray with an optical density of 0.7 had the same density, and the reproducibility of each was evaluated.

Also, from the spectral sensitivity distribution, from the distribution at the lowest density +0.1, the maximum sensitivity at the lowest density +0.1 (hereinafter referred to as maximum sensitivity) of the spectral sensitivity distribution of the blue-sensitive layer, and the lowest density +0.1 at 480r++w. A comparison was made of the spectral sensitivity (hereinafter referred to as 480 nm sensitivity) in No. 1. The comparison of sensitivity was quantified using the following formula.

Table 1 shows the results of evaluation based on two items, including sensitivity of 480r+m. In Table 1, in the column of maximum sensitivity wavelength, the wavelength that provides the maximum sensitivity of the spectral sensitivity distribution at the minimum density of the blue-sensitive layer +0.1 is listed.
