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 photographic light-sensitive material having improved color reproducibility, and more particularly to a silver halide color photographic light-sensitive material having improved red and purple color reproducibility.

[0002]

2. Description of the Related Art In recent years, silver halide color photographic light-sensitive materials have been remarkably improved in image quality. That is, in the recent silver halide color photographic light-sensitive materials, the graininess and sharpness of color reproducibility, which are the three major factors of image quality, have reached quite high levels. For example, "Konica Color Impreza 5
0 ”has been well received in the market for its high image quality.

However, among the above three elements, although the color reproducibility has been improved in color purity, the hue reproducibility and the shadow depiction power are still insufficient in many points. In particular, since red, magenta, and purple are frequently photographed as main subjects, there is great potential need for faithful reproduction of hue reproducibility, color purity, and shading.

It is well known in the art that there are a correlation effect (inter-image effect) and a spectral sensitivity distribution as major factors related to color reproducibility, but conventional color photographic light-sensitive materials mainly use color purity. It has been designed and developed by giving priority to increasing it.

Therefore, a known so-called DIR compound is used in order to increase the inter-image effect, or in a color negative film, the colored coupler is used more than to cancel the unnecessary absorption to give the same effect as the inter-image effect. It has been used to improve color purity.

On the other hand, in the spectral sensitivity distribution, in order to reduce the overlap of the blue-sensitive, green-sensitive and red-sensitive spectral sensitivity distributions, the shapes have been sharpened or separated from each other to contribute to color purity.

However, in recent years, problems have arisen in the hue reproduction of intermediate colors and the faithful reproducibility of delicate shades and shades of primary colors, which is an adverse effect of the above technology. It is effective to make the spectral sensitivity distribution of the red-sensitive layer into a short wave for the hue reproduction of the intermediate color, especially for violet, JP-A-3-194546 and 3-194547.
It is publicly known as described in No. 3-107139, No. 3-265845, No. 3-273239 and the like.

The purpose of these techniques is to sense the spectral reflectance peculiar to purple at a wavelength close to human eyes.

However, as a matter of course, if the spectral sensitivity distribution of red sensitivity is set to a short wave, the color purity of red will be significantly deteriorated. Therefore, it is possible to make the spectral sensitivity distribution of red sensitivity shortwave and increase the inter-image effect, but it is still insufficient at present. Furthermore, it was revealed that the distinctiveness of various violet colors was insufficient only by making the spectral sensitivity distribution of red sensitivity short.

On the other hand, Japanese Patent Application Laid-Open No. 63-85545 and Japanese Patent Application Laid-Open No. 4-274422 have disclosed the technology for red with respect to the subtle shading of primary colors and faithful reproducibility of shading. These are problems that the gradation of the complementary color disappears or becomes soft in the image area that reproduces the primary color of the subject as a harmful effect of the inter-image effect that is increased too much. It is shown by controlling optimally.

However, although these disclosed technologies describe differences in red lightness or changes in brightness, they are not a technical solution for discriminating the hue change and the brightness change of an object having different spectral reflectances. .

That is, the red color is sufficient to satisfy its purity,
Further, it is not possible to improve the distinctiveness of red and violet having different spectral reflectances by the easy combination of the spectral sensitivity distribution and the inter-image effect which have been mainly used conventionally.

Further, an important mission of the color photographic light-sensitive material in the market is to store the image photographed by the user without changing it forever, but in the color light-sensitive material using some magenta couplers, it is developed. It has been found that there is a problem in that after storage after processing, especially in storage at high temperature and high humidity, remarkable color increase occurs, and the hue and saturation are completely different from those immediately after development processing.

The present inventors have arrived at the present invention by studying how to optimally give cyan density when photographing these subjects by sampling various red and purple spectral reflectances.

[0015]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The object of the present invention is to halogenate a red color, which is sufficiently satisfactory in its purity, and which is excellent in distinguishability of red and purple having different spectral reflectances, and which is excellent in image preservation. It is to provide a silver color photographic light-sensitive material.

In the general formula [M-1], Z represents a non-metal atom group necessary for forming a nitrogen-containing heterocycle, and the ring formed by Z may have a substituent. X represents a hydrogen atom or a group capable of leaving by a reaction with an oxidized product of a color developing agent, and R represents a hydrogen atom or a substituent. (2) The silver halide color photographic light-sensitive material as described in (1) above, wherein the wavelength λmax giving the maximum sensitivity of the spectral sensitivity distribution of the red-sensitive silver halide emulsion layer is 610 nm ≦ λmax ≦ 645 nm. The present invention will be described in more detail.

The red filter A used in the present invention means that the spectral transmittance of 350 nm to 585 nm is 2% or less, the wavelength having the transmittance of 50% is 600 nm to 610 nm, and the transmittance of 630 nm to 800 nm is 80% or more. In the commercially available filter, the Ratten gelatin filter No. manufactured by Eastman Kodak Co. is used. There are 26 and so on. The red filter B has a spectral transmittance of 2% or less at 350 nm to 620 nm.
The wavelength with 50% transmittance is 635nm to 645nm and 665n
It is a filter with a transmittance of 80% or more from m to 800 nm,
Among commercially available filters, Eastman Kodak Company's Ratten Gelatin Filter No. For example, 92.

Γ _A and γ _B in the present invention are determined as follows.

First, the ISO 5800 (19
79) Obtain the ISO sensitivity by the method specified in [E]. Next, the same ISO sensitivity was obtained with the light source having the same relative spectral energy distribution as that used for obtaining the ISO sensitivity for the test sample of the silver halide color photographic light-sensitive material whose ISO sensitivity was S. 16 depending on exposure time
Wedge exposure is given through the above-mentioned red filter A with an exposure amount of 00 / S.lux.sec. Similarly, for the test sample, the same light source as above and exposure time of 6400 / S.lux.
A wedge exposure is given through the red filter B with an exposure amount of sec.

Until the two types of test samples exposed by the above red filters A and B are developed, the temperature is kept at 20 ± 5 ° C. and the relative humidity is 60 ± 10%, and the development is conducted for 30 minutes or more after the exposure. It shall be completed within 6 hours and the processing method shall be as recommended by the film manufacturer.

After the development processing, the density is measured in accordance with the status M of ISO5 / 3-1984 (E) in the case of a color negative photosensitive material for photographing a test sample, and in other cases ISO5 / 3-1984.
Perform in accordance with status A of (E).

Based on the obtained density data, the minimum density of cyan density is +0.4, +0.6, +0.8, +1.0 on a graph in which the horizontal axis is the logarithm of the exposure amount and the vertical axis is the density. The values that give the concentrations of Pt are plotted, these points are approximated by a straight line by the method of least squares, and tan θ is set to γ with respect to the angle θ from the horizontal axis (where 0 ≦ θ <π / 2).

At this time, γ obtained from the test sample exposed by the red filter A is defined as γ _A, and γ obtained from the test sample exposed by the red filter B is defined as γ _B.
The preferred range of γ _B / γ _A in the present invention is 1.1 ≦ γ _B /
γ _A ≦ 1.8, more preferably 1.15 ≦ γ _B / γ _A ≦ 1.5. Although it seems that setting γ _B / γ _A to 1 or more is similar to making the gradation of the complementary color for a red subject seem to be harder, the present inventors have found that various red and purple colors are used. It was found that it is necessary to control the partial gradation in the exposure amount range having the density described above by measuring the cyan gradation by measuring the spectral reflectance of the subject.

In the present invention, it is preferable that the spectral sensitivity λmax of the red-sensitive silver halide emulsion layer is 610 nm to 645 nm because the violet discriminability is particularly good. The wavelength λmax, which gives the maximum sensitivity of the spectral sensitivity distribution of the red-sensitive silver halide emulsion layer, is determined by measuring the spectral sensitivity distribution at the density of cyan fog +0.1 in the case of a color negative type light-sensitive material. In the case of a color reversal light-sensitive material, it means the wavelength to give the maximum sensitivity by measuring the spectral sensitivity distribution at the maximum cyan density of −0.3.

The preferable range of λmax obtained here is 6
10 nm ≦ λmax ≦ 640 nm.

As one of the preferable embodiments of γ _B / γ _A and λ max in the present invention, the silver halide emulsion is a spectrum represented by the following general formulas [I], [II], [III] and [IV]. This can be achieved by using sensitizing dyes alone or in combination, but is not necessarily limited to these spectral sensitizing dyes.
