Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a color photographic material that is highly sensitive and has excellent brown color reproducibility.

(Prior Art) Several attempts have been made to achieve faithful color reproduction when photographing color photographic materials under various light sources. US Patent 3. 672. No. 898 enables faithful color reproduction by limiting the spectral sensitivity distribution of blue-, green-, and red-sensitive silver halide emulsions to a certain range, and in particular shortens the spectral sensitivity distribution of the red-sensitive layer to improve the quality of light-sensitive materials. A technique has been disclosed that improves the reproducibility of purple colors, which has a spectral sensitivity similar to that of the eye.

Here, the higher the photographic sensitivity is, the more opportunities to take pictures under different types of light sources, so techniques for improving the color reproducibility of highly sensitive photographic materials under different types of light sources are important.

However, if the technique shown here which shortens the spectral sensitivity of the red-sensitive layer and improves color reproducibility under different types of light sources is used, the sensitivity decreases. If you try to compensate for these decreases in sensitivity by increasing the size of the silver halide grains, the graininess will worsen, but the larger the grain size, the more the sensitivity will increase relative to the increase in size. Due to the inefficiency factor of emulsion grains, which are small, the deterioration of graininess becomes more problematic as the grain size increases, that is, as the sensitivity increases.

Furthermore, when the above means is used, there is a problem in that although the fidelity of color reproduction increases, the chromaticity decreases.

Furthermore, in order to improve color reproducibility, attempts were made to improve color saturation by strengthening masking using colored couplers, including JP-A-61-221,748 and JP-A-62-3,253.
, JP-A-61-43,743, JP-A-62-160,4
48 and JP-A-62-160,449, etc., however, they had a serious drawback in that the sensitivity of the red-sensitive layer was reduced when the masking was strengthened using a magenta colored coupler.

Japanese Patent Application No. 62-285,586 discloses that among the red-sensitive silver halide emulsion layers, the ratio of the magenta color tone uncoupler in the lower-sensitivity layer is higher than that in the high-speed layer. However, this was not sufficient to sufficiently increase the color saturation of subjects photographed with appropriate exposure.

If the masking is strengthened by increasing the amount of the magenta color tone uncoupler, the long wavelength side of the absorption spectrum of the magenta color tone uncoupler will overlap with the short wavelength side of the spectral sensitivity of the red-sensitive layer. The sensitivity of the layer decreases. Therefore, considering only the sensitivity, it is preferable to include as much of the magenta color tone uncoupler as possible in the least sensitive emulsion layer among the red-sensitive emulsion layers. However, when considering color reproduction, especially the saturation of red, the masking effect only from the lowest sensitive layer is disadvantageous when photographing in the appropriate exposure range.

(Problems to be Solved by the Invention) An object of the present invention is to provide a color photographic material that exhibits little change in color tone when used under daylight or fluorescent lamps. The object of the present invention is to provide a color photographic material that maintains particularly high sensitivity, high chromaticity, faithful color reproducibility, and whose color reproducibility does not change under various light sources.

(Means for solving problems) The object of the present invention has been achieved by the following configuration.

tll A silver halide photographic photosensitive material having two or more red-sensitive silver halide emulsion layers, one or more green-sensitive silver halide emulsion layers, and a blue-sensitive emulsion layer each on a support, and having a ■So sensitivity of S. In the material, the photosensitive material is 2/S

3≦3, sso 31iso≦0. 3, and the magenta color tone uncoupler contained in the red-sensitive silver halide layer having the second highest sensitivity after the highest sensitivity layer among the red-sensitive silver halide emulsion layers is present in all the red-sensitive silver halide emulsion layers. A silver halide photographic light-sensitive material, characterized in that the ratio of the total amount of magenta color tone uncoupler contained therein is 80% by weight or more.

(2) The silver halide photographic light-sensitive material according to claim 1, wherein the specific photographic sensitivity of the light-sensitive material is 320 or higher.

How to obtain 36see, S, and sso mentioned here will be explained and defined in detail below. Color photographic material I
The method for measuring SO sensitivity is l5O5800-1979(E)
Obtained by the method prescribed by.

Using a light source with the same relative spectral energy distribution as that used to determine the ISO sensitivity of a color photographic material with an ISO sensitivity of S, and using the same exposure time as that used to determine the ISO sensitivity, 2 X l / S 1ux- A uniform exposure is given to the light-sensitive material to be tested at an exposure amount of . At this time, the test is conducted indoors at a temperature of 20±5° C. and a relative humidity of 60±10%, and the photosensitive material to be tested is left in this state for at least one hour before use. Within hours after uniform exposure, exposure with varying illuminance is given using monochromatic light of 580 nm. As with the measurement of ISO sensitivity, the exposure device is of the non-intermittent exposure/illuminance still type, and changes in illuminance are achieved by a light modulator such as an optical wedge. The exposure time is 1/10 seconds. The monochromatic light of 580nm here means that the peak wavelength of relative spectral energy is 580±2nm, and the half-value is 20nm.
Say the following things. To obtain this monochromatic light, a common exposure light source such as a tungsten lamp may be combined with a commercially available interference filter.

After exposure to monochromatic light, the photosensitive material to be tested is kept at a temperature of 20 ± 5°C and a relative humidity of 60 ± 10% until development processing, and development processing is completed within 30 minutes or more and within 6 hours and 1 hour after exposure. The processing and processing methods shall be as recommended by the film manufacturer. Concentration measurements are performed using blue, green, and red filters having the spectral characteristics shown in FIG. 1. The detailed conditions of the measurement method conform to the ISO method.

Photographic sensitivity, 3, 4@0, S, 5e11 are the minimum density (
The exposure amount at a point with a density of +0.6 (after giving uniform exposure) is HG"olux-sec % HR"01uxes
It is calculated according to the following formula when ec is assumed to be ec.

The present inventors studied the technology disclosed in JP-A-62-160448 in order to obtain design guidelines for a color photographic material that exhibits little change in color when photographed under fluorescent light or under daylight. However, it was not possible to achieve this goal while maintaining color saturation and fidelity. In other words, since the finish becomes greenish under fluorescent light, we focused on the spectral sensitivity distribution of the green-sensitive layer and conducted various studies, but When trying to satisfy changes in taste, it was not possible to maintain color saturation, and when trying to satisfy changes in color saturation and color under fluorescent light, faithful color reproducibility could not be achieved. As a result of intensive study, monochromatic light sensitometry at various wavelengths measured after uniform exposure as described above revealed that 36sso at 580 nm in particular. ss
It has been found that it is important to keep o within a certain range. The reason for this is not clear, but the fact is that color photosensitive materials for photography often use reflective objects with a certain degree of color as the subject, and that it is due to some correlation with the energy distribution of general fluorescent lamps that they are monochromatic with a certain amount of white light mixed in. Optical sensitometry may have made it possible to design sensitive materials that minimize changes in color under fluorescent light.

In order to achieve the 3661@311sso of the present invention, known techniques such as selection of appropriate sensitizing dyes and introduction of filter layers using various dyes can be used.

In the present invention, the specific photographic sensitivity as detailed and defined below is employed as the sensitivity of the photographic light-sensitive material for the following reasons.

In other words, ISO sensitivity, which is an international standard, is generally used for the sensitivity of photographic light-sensitive materials, but ISO sensitivity stipulates that the light-sensitive material must be developed on the fifth day after exposure, and that the development process must be in accordance with the processing specified by each company. Therefore, in the present invention, the time from exposure to development processing is shortened (0.5 to 6 hours),
In addition, the following specific photographic sensitivity was adopted so that the sensitivity was determined by a certain development process.

The specific photographic sensitivity of a light-sensitive material as used in the present invention is determined according to the following test method based on ISO sensitivity.

The present invention provides a highly sensitive photographic material with high effects.

In other words, when photographing a subject under multiple types of light sources, it is often dark, and when using low-sensitivity photosensitive materials, the flash will emit when photographing with a camera equipped with an automatic strobe. This is because the area other than the area where the flash light is reaching is very difficult to photograph.For this reason, there is no need to be conscious that the area is being irradiated by a different light source.However, with high sensitivity photographic materials When using a flash, there is a high possibility that the flash will not fire if the camera is equipped with an automatic strobe when there is a certain level of brightness, and the problem is that the camera is illuminated by a different light source. becomes.Also,
Even when a flash fires, a high-sensitivity camera has greater ability to depict the background, so the difference in color balance between the part of the main subject illuminated by the flash and the part of the background illuminated by a different light source can easily become a problem.

Furthermore, one of the effects of the present invention is that color reproducibility is improved without causing a decrease in sensitivity, but when color reproducibility is improved using conventional technology, a decrease in sensitivity is unavoidable. In order to compensate for this decrease in sensitivity, the size of the silver halide grains is often increased, but in this case the graininess deteriorates. Here, due to the inefficiency of silver halide grains in which the larger the grain size, the lower the sensitivity/volume ratio1, sensitivity can be increased by increasing the grain size in large grains, that is, in the high sensitivity region. The deterioration in graininess is greater than in the low-sensitivity region.

Therefore, the present invention, which can improve color reproducibility without causing a decrease in sensitivity, is highly useful for highly sensitive photographic materials.

The photographic material of the present invention shows an improvement effect in all photographic sensitivities, but the photographic sensitivity determined by the above method is 320.
The above are more preferred. If the sensitivity is less than 320, in addition to the above-mentioned reasons, the probability of failures such as out-of-focus and insufficient exposure during normal photographing increases.

(U tl 1ha δU3 The light-sensitive material of the present invention can be used as long as at least one silver halide emulsion layer of a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer is provided on the support. There is no particular restriction on the number and order of silver halide emulsion layers and non-light-sensitive layers. A silver halide photographic light-sensitive material having at least one light-sensitive layer consisting of a plurality of silver halide emulsion layers, the light-sensitive layer comprising units sensitive to blue light, green light, or red light. It is a photosensitive layer, and in multilayer silver halide color photographic light-sensitive materials, the unit photosensitive layers are generally arranged in the following order from the support side: a red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer. However, depending on the purpose, the above-mentioned installation order may be reversed, or the installation order may be such that different photosensitive layers are sandwiched between the same color-sensitive layer.

Non-photosensitive layers such as various intermediate layers may be provided between the above-mentioned silver halide photosensitive layers and between the uppermost layer and the lowermost layer.

The intermediate layer includes JP-A Nos. 61-43748 and 59-1.

It may also contain a commonly used color mixing inhibitor.

A plurality of silver halide emulsion layers constituting each unit photosensitive layer are composed of a high-speed emulsion layer and a low-speed emulsion layer, as described in West German Patent No. 1,121,470 or British Patent No. 923,045. A two-layer structure can be preferably used0
Usually, it is preferable to arrange the halogen emulsion so that the intensity of light decreases toward the support, and a non-photosensitive layer may be provided between each halogen emulsion layer.
No. 112751, No. 62-200350, No. 62-2
As described in Nos. 06541 and 62-206543, a low-sensitivity emulsion layer may be provided on the side far from the support, and a high-sensitivity emulsion layer may be provided on the side close to the support.

They can also be arranged in the order of H/GL/RL. Alternatively, as described in JP-A-56-25738 and JP-A-62-63936, the blue-sensitive layer/GL/RL/Gll/RH may be arranged in this order from the farthest side from the support. .

In addition, as described in Japanese Patent Publication No. 49-15495, the upper layer is a silver halide emulsion layer with the highest sensitivity, the middle layer is a silver halide emulsion layer with lower sensitivity, and the lower layer is more sensitive than the middle layer. An example is an arrangement consisting of three layers with different photosensitivity, in which a silver halide emulsion layer with a low density is disposed and the photosensitivity gradually decreases toward the support. Even when it is composed of three layers with different photosensitivity, as described in JP-A No. 59-202464,
In the same color-sensitive layer, medium-sensitivity emulsion layer/high-sensitivity emulsion layer/low-sensitivity emulsion layer may be arranged in this order from the side remote from the support.

All known methods described in No. 3, No. 58-14834, and No. 60-220345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be performed. An example of this is a stabilization bath containing a dye stabilizer and a surfactant, which is used as a final bath for color photographic materials. Examples of the dye stabilizer that can be used include aldehydes such as formalin and glutaraldehyde, N-methylol compounds, hexamethylenetetramine, and aldehyde sulfite adducts.

It is also possible to add various botanical agents and antifungal agents to this stabilizing bath.

The overflow liquid from water washing and/or replenishment of the stabilizing liquid can be reused in other processes such as the desilvering process.

When each of the above-mentioned processing liquids is concentrated by evaporation in processing using an automatic processor or the like, it is preferable to correct the concentration by adding water.
