Description

TECHNICAL FIELD The present invention relates to a silver halide multilayer color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material having high chroma and excellent in faithful color reproducibility of primary colors and intermediate colors. Regarding materials.

(Prior Art) As is well known, a silver halide multilayer color photographic light-sensitive material comprises a support such as cellulose ester or polyester, a red-sensitive silver halide emulsion layer containing a diffusion-resistant cyan image-forming coupler, A green-sensitive silver halide emulsion layer containing a diffusible magenta color image-forming coupler and a blue-sensitive silver halide emulsion layer containing a diffusion-resistant yellow color image-forming coupler are laminated.

One factor that governs color reproducibility in a color negative photographic light-sensitive material having the above layer structure is spectral sensitivity distribution.
The silver halide multilayer light-sensitive material is provided with a red-sensitive layer, a green-sensitive layer and a blue-sensitive layer, each of which has sensitivity to light in a predetermined wavelength range. However, the color sensitivity of each of these photosensitive layers is not fixed in each wavelength region, and varies depending on the spectral sensitizer and other materials used, and therefore has different spectral sensitivity distributions. ing.
Therefore, the position of the peak and the overlap of the hem of the spectral sensitivity distribution change depending on the selection and combination of the respective photosensitive layers, which is a major factor controlling the color reproducibility of the color photosensitive material.

Due to recent technological advances in silver halide multilayer color photographic light-sensitive materials, good color reproduction can be obtained if the exposure conditions during shooting are appropriate and the subsequent processing, printing, and projection conditions are also appropriate. It has become to. However, if these are not properly performed, sufficient color reproduction may not always be obtained, and it is a matter of concern for those skilled in the art to try to improve this point by improving color photographic light-sensitive materials. is there.

The exposure conditions at the time of shooting include excess and deficiency of exposure amount, exposure time, light amount distribution (illumination condition) of a subject, color temperature of a light source, and the like.
Therefore, for example, in order to provide a photographic light-sensitive material which is faithful in color reproducibility and whose color reproducibility does not change greatly under photographing conditions under various light sources, the spectral sensitivity of blue, green, and red-sensitive silver halide emulsion layers is used. US Pat. No. 3,672,898 discloses a method for limiting the distribution to a certain range by selecting and combining a spectral sensitizing dye and a filter dye.

The present inventor has studied various combinations of the above means,
It has not been possible to obtain a light-sensitive material that is sufficiently satisfactory in both saturation and hue fidelity. This is because the overlapping of the spectral sensitivity distributions of the red-sensitive layer and the green-sensitive layer is increased, resulting in color mixture (color turbidity) due to poor color separation, resulting in a decrease in saturation.

Poor color separation can be prevented by selecting a spectral sensitizing dye with a sharp end in the spectral absorption spectrum.However, the actual spectral sensitizing dye has a limit in sharpness, especially at the short wavelength end. Is extremely difficult. As described in US Pat. No. 3,672,898, if a filter dye is used, the short wavelength end can be sharply cut to some extent, but at the same time, light absorption occurs at a portion corresponding to the wavelength of the filter dye. It exerts an unfavorable effect by giving an unnecessary influence to the spectral sensitivity distribution of other layers or reducing the sensitivity.

Generally, in order to reduce the change in color reproducibility due to the change in color temperature of the light source at the time of shooting, the main region of the spectral sensitivity distribution of the blue sensitive layer is moved to the longer wave side and that of the red sensitive layer is moved to the shorter wave side, that is, blue. It is effective to reduce the sag on the wavelength of the spectral sensitivity distribution among the sensitive layer, the green sensitive layer, and the red sensitive layer. However, as described above, this is likely to cause color separation failure and Color reproduction is reduced. Conversely, if the slope of the spectral sensitivity distribution among the blue-sensitive layer, the green-sensitive layer, and the red-sensitive layer is made larger, the color separation will be better and the saturation will not decrease, but the color temperature of the light source The change in the color reproducibility due to the change of becomes too large.

Color photographic light-sensitive materials are expected to reproduce various colors with the same brightness and color as seen by the human eye.
The color that humans perceive visually depends on the spectral distribution of absorption or emission of the object and the color temperature of the light source that illuminates the object, but the difference in the color temperature of the light source is a relatively small difference to the human eye. However, in the color photographic light-sensitive material, a larger difference is detected. This is because, firstly, the relative sensitivities of the three sensory organs in the human visual spectrum change depending on the color temperature and brightness of the light source, and secondly, the spectral sensitivity distributions of the three sensory organs are color photographs. This is also because it is different from the spectral sensitivity of the photosensitive material. And the difference in spectral sensitivity distribution between the sensory organs and the color photographic light-sensitive material is
For one color, it is recognized that the color reproduced by the color photographic light-sensitive material and the color directly observed with the naked eye are visually the same, but for another color, they are completely different colors. It also causes the phenomenon of being perceived.

The spectral sensitivity of the human eye has peaks near 445 nm, 540 nm, and 605 nm for three sensory organs, but many of the color photographic materials currently on the market, such as the color-sensitive film, have a blue-sensitive layer. It is known that the peak is at a wavelength shorter than 445 nm, the peak of the green-sensitive layer is slightly longer than 540 nm, and the peak of the red-sensitive layer is much longer than 605 nm. this is,
For example, if you use a color negative film with color balance under daylight and shoot under tungsten light in which the long-wavelength component of the spectral distribution in the visible region is relatively larger than the short-wavelength component compared to daylight, you can see it visually. An image with a stronger orange tint will be reproduced than when it is turned off. This is mitigated by shifting the spectral sensitivity of the blue sensitive layer to a longer wavelength and the spectral sensitivity of the red sensitive layer to a shorter wavelength. As described above, this simultaneously increases the overlap of the spectral sensitivity distributions between the layers, which causes deterioration in color reproducibility due to defective color separation.

It is known to utilize the interlayer suppression effect for improving color reproducibility. In the case of a color negative photosensitive material, by giving a phenomenon suppressing effect from the green sensitive layer to the red sensitive layer, the color development of the red sensitive layer in white exposure can be suppressed more than that in the case of red exposure. Since the system of color negative paper is balanced in gradation so that it is reproduced in gray on a color print when it is exposed to white light, the above-mentioned multi-layer effect is higher in density when it is exposed to red than when it is exposed to gray. As a result of giving the cyan color development, it is possible to give a more saturated red reproduction with suppressed cyan color development on the print. Similarly, the effect of suppressing the phenomenon from the red-sensitive layer to the green-sensitive layer gives a highly saturated reproduction of green.

As a method of enhancing the multi-layer effect, it is known to increase the iodide content of the emulsion or use a DIR compound. However, the conventionally known DIR compounds are not always sufficient in the effect of improving color reproducibility, and have no effect in improving the deterioration of color reproducibility when the overlap of spectral sensitivity distributions is increased.

Maximum sensitivity of spectral distribution of blue, green, and red-sensitive silver halide emulsion layers for the purpose of providing color photographic materials with little change in color reproducibility due to change in color temperature of light source during photography and high color reproducibility. Japanese Patent Application Laid-Open No. 59-131937 discloses a method of defining the width of the powder and containing a diffusible DIR compound.

The present inventor has tried various combinations of the above means, and obtains a light-sensitive material satisfying both changes in color reproducibility due to changes in color temperature of a light source during photographing, high saturation, and faithful reproduction of primary colors and intermediate colors. I couldn't do that. This is because the limitation of the maximum sensitivity width and the use of the diffusive DIR compound alone can reduce the change in the color reproducibility due to the change in the color temperature of the light source at the time of shooting and increase the saturation of some colors, Objects with intermediate colors other than the primary colors that exist in nature in large numbers,
This indicates that the skin color and the like cannot be faithfully reproduced.

(Problems to be Solved by the Invention) An object of the present invention is to provide a new silver halide multilayer color photographic material, and more specifically, there is little change in color reproducibility due to change in color temperature of a light source during photographing. At the same time, the object is to provide a silver halide color photographic light-sensitive material having high saturation of the color reproduced at that time and excellent in faithful color reproducibility of primary colors and intermediate colors.

(Means for Solving Problems) The object of the present invention is achieved by the following silver halide color photographic light-sensitive material.

A blue-sensitive silver halide emulsion layer containing at least one layer of a color coupler that develops yellow, a green-sensitive silver halide emulsion layer containing a color coupler that develops magenta, and a red containing a color coupler that develops cyan on the support. In a color light-sensitive material having a sensitive silver halide emulsion layer, the spectral sensitivity distribution S of the blue-sensitive silver halide emulsion layer is
_B (λ) is And the spectral sensitivity distribution S _G (λ) of the green-sensitive silver halide emulsion layer
But And the spectral sensitivity distribution S _R (λ) of the red-sensitive silver halide emulsion layer
But And the magnitude of the interlayer effect is −0.15 ≦ D _B / D _R ≦ + 0.20 −0.70 ≦ D _G / D _R ≦ 0.00 −0.50 ≦ D _B / D _G ≦ 0 _{.00 -1.10 ≦ D R / D G} ≦ -0.10 -0.45 ≦ D G / D B ≦ -0.05 -0.05 ≦ D R / D B ≦ + 0.35 ( However, D _B / D _R is from red sensitive layer to blue sensitive layer, D _G / D _R
Is a red-sensitive layer to a green-sensitive layer, D _B / D _G is a green-sensitive layer to a blue-sensitive layer, D _R / D _G is a green-sensitive layer to a red-sensitive layer, and D _G / D _B is a blue-sensitive layer to a green-sensitive layer. , D _R / D _B respectively represent the magnitude of the interlayer effect from the blue-sensitive layer to the red-sensitive layer), and a silver halide color photographic light-sensitive material.

In the present invention, the wavelengths λ ^max and S that maximize S (λ)
The wavelengths λ ⁸⁰ and S at which (λ) is 80% of S (λ ^max ).
The wavelengths λ ⁶⁰ and S at which (λ) is 60% of S (λ ^max ).
The preferable range of the wavelength λ ⁴⁰ where (λ) is 40% of S (λ ^max ) is as follows for each spectral sensitivity distribution.

(I) S _B (λ) (Ii) S _G (λ) (Iii) S _R (λ) The preferable ranges of the magnitude of the interlayer effect (that is, the interlayer suppression effect) are as follows.

−0.10 ≦ D _B / D _R ≦ + 0.15 −0.55 ≦ D _G / D _R ≦ −0.05 −0.45 ≦ D _B / D _G ≦ −0.05 −0.90 ≦ D _R / D _G ≦ −0.15 −0.40 ≦ D _G / D _B ≦ −0.10 0.00 ≦ D _R / D _B ≦ + 0.30 Hereinafter, the present invention will be described in detail.

To achieve the object of the present invention, the present inventor first needs to match the spectral sensitivity distributions of the blue-sensitive layer, the green-sensitive layer and the red-sensitive layer with the spectral sensitivity distributions of the three sensory organs of the eye. I thought it was. U.S. Pat. No. 3,672,898 defines the range of peak wavelengths of each photosensitive layer in the vicinity of the peak wavelength of the spectral sensitivity distribution of the three sensory organs of the human eye. However, the range of the peak wavelength specified here is too narrow to be practical. That is, in order to obtain the specified peak wavelength, the selection of the type of sensitizing dye to be used is extremely limited, and as a result, the effect of color sensitization and supersensitization is not substantially obtained, and the sensitivity is low. However, there is a drawback that only a photographic light-sensitive material having a fatal defect such as being easily affected by formalin gas can be obtained.

On the other hand, as disclosed in JP-A-59-131937, when a diffusible DIR compound is contained to improve the saturation due to the inter-layer suppressing effect, the saturation of a part of the colors can be increased, but the intermediate color Faithful color reproduction becomes difficult.

The present inventor eliminates all of the above-mentioned drawbacks of the prior art by defining the spectral sensitivity distribution of each photosensitive layer and the magnitude of the inter-layer suppression effect between the photosensitive layers in a specific range. That is, it was found that a light-sensitive material having high saturation and excellent reproducibility of primary colors and intermediate colors can be obtained.

In the present invention, when the spectral sensitivity distribution of the green-sensitive layer and the red-sensitive layer is set to a longer wavelength side than the above range, the light source dependency at the time of photographing becomes large, and when it is set to a short wavelength side, color separation becomes poor and color turbidity occurs. , Causes a decrease in saturation. On the other hand, when the spectral sensitivity distribution of the blue-sensitive layer is set to a longer wavelength side than the above range, color separation is deteriorated, color turbidity occurs and the saturation is lowered, and when it is set to a short wavelength side, the light source dependency at the time of shooting is increased, In addition, static marks are likely to occur.

In the present invention, when the magnitude of the interlayer effect exceeds the specified range, color turbidity increases and saturation decreases. If it is lower than the specified range, the saturation is improved, but the reproduction of colors such as intermediate colors is not faithful, the tone reproduction of the color gradation is insufficient, and the so-called color blinding phenomenon occurs.

As described above, even if the spectral sensitivity distribution is specified in the above range, if the magnitude of the interlayer effect is outside the range, the color temperature dependency of the light source is improved, but the saturation is deteriorated due to the color separation failure. Occurs, and faithful color reproduction cannot be obtained. On the other hand, even if the magnitude of the interlayer effect is specified in the above range, if the spectral sensitivity distribution is outside the range, although the saturation is improved, the color temperature dependence of the light source is not improved, rather Getting worse. Reduces the change in color reproducibility due to the change in color temperature of the light source during shooting,
In addition, in order to achieve high saturation and faithful reproduction of primary colors and intermediate colors, each photosensitive layer must have a specific spectral sensitivity distribution and an interlayer suppression effect of a specific size, as described above. is necessary.

In the present invention, the interlayer effect is obtained as follows. For example, the interlayer effect from the green-sensitive layer to the red-sensitive layer (D _R
/ D _G), first green light (Fuji filter: BPN-5
After stepwise exposure in 5), it was uniformly exposed with red light (Fuji filter: SC-60).
In the characteristic curve shown in FIG. 4, the fog density and the magenta density difference (Δy) between the fog density and the density at an exposure amount Q that is 1.5 times larger than the exposure amount P by which the fog density is given, and the cyan density at the exposure amount P and the exposure The cyan concentration difference (Δx) from the silane concentration in the amount Q is determined, and Δx / Δy is used as a measure of the magnitude of the interlayer effect (D _R / D _G ) from the green-sensitive layer to the red-sensitive layer. The interlayer effect from the blue-sensitive layer to the red-sensitive layer can be similarly obtained by using blue light (Fuji Filter: BPN45).

When Δx is a negative value, the interlayer suppressing effect is effective, and the interlayer suppressing effect is represented by a negative value. When Δx is a positive value, the inter-layer suppression effect is not effective (cloudy), and its magnitude is represented by a positive value.

By the way, in recent years, the masking material has been remarkably improved, and the turbidity of the color due to unnecessary absorption of the color coupler that develops each color has been sufficiently corrected in practice. Therefore, in this specification, the magnitude of the inter-layer effect is substantially indicated by a value after correcting the influence of unnecessary absorption of the color coupler that develops each color.

In the present invention, the spectral sensitivity distributions of the blue-sensitive layer, the green-sensitive layer and the red-sensitive layer can be obtained, for example, by appropriately combining spectral sensitizing dyes having the structural formulas shown below.

Blue-sensitive silver halide emulsion layer Green-sensitive silver halide emulsion layer Red-sensitive silver halide emulsion layer The diffusible DIR compound is effective even if it is contained in only one of the blue-sensitive layer, the green-sensitive layer and the red-sensitive layer, but it is preferably contained in two or more layers to obtain better color reproduction. Further, if a leaving group is released by substantially causing a coupling reaction with an oxidized product of a color developing agent that has diffused from other layers during color development, it does not contain silver halide itself,
Alternatively, it may be contained in a layer having no color sensitivity.

It is also possible that a certain color-sensitive layer is divided into two or more layers, the diffusible DIR compound is contained in one or more layers, and the other layers are not contained. At that time, the sensitivities of the plurality of layers may differ from each other as in the so-called high-sensitivity layer and low-sensitivity layer, and the color sensitivities may not be exactly the same.

Further, in order to arbitrarily change the degree of interlayer suppression effect, the iodine content of the emulsion may be appropriately changed, or a method of adding a colored coupler to mask unnecessary absorption of the color forming dye may be used. A method may be used in which a coloring dye different from the above is intentionally mixed in to increase the color turbidity and cancel the interlayer suppression effect.

Was subjected to wedge exposure with white light of 4800 ° K and subjected to the following color development processing, and almost the same sensitivity and gradation were obtained.

Therefore, the above-described exposure for evaluation of the multilayer effect was performed, and similarly, the following color development processing was performed. The results are shown in Table 1, and the spectral sensitivity distribution is shown in FIG. Further, the range according to the present invention of the spectral sensitivity distribution of each photosensitive layer, which is inductively derived from FIG. 5, is shown in FIGS.

The developing process used here is as follows.

1. Color development: 3 minutes 15 seconds (38 ° C) 2. Bleaching …… 6 minutes 30 seconds 3. Washing with water …… 3 minutes 15 seconds 4. Fixed arrival …… 6 minutes and 30 seconds 5. Washing with water …… 3 minutes 15 seconds 6. Stability: 3 minutes 15 seconds The composition of the treatment liquid used in each process is as follows.

When the measurement was performed using a filter matched with the spectral sensitivity distribution of # 653-258, magenta and cyan color images having the same characteristic curve as in FIG. 4 were obtained.

Here, Δx indicates the degree of the interlayer effect in which the uniformly fogged cyan emulsion layer is suppressed when the green-sensitive emulsion layer is developed from the unexposed portion (point A) to the exposed portion (point B). .

That is, in FIG. 4, the curve AB represents the characteristic curve relating to the magenta color image of the green photosensitive layer, and the curve ab represents the cyan color image density of the red photosensitive layer by uniform red exposure. P represents a fog portion of a magenta color image, and Q represents an exposure amount (P + 1.5) giving a magenta color image density of fog density + Δy.

The difference between the cyan color image density (a) at the exposure amount P and the cyan color image density (b) at the same exposure amount Q was calculated and designated as Δx. Cyan color image density change rate (Δx / Δ) corresponding to magenta color image density change
y) is the interlayer effect from the green-sensitive layer to the red-sensitive layer (D _R /
_DG ). When the value of Δx is negative, the effect of suppressing the interlayer is effective, and the magnitude thereof is represented by a negative value. Further, when Δx is positive, the inter-layer suppressing effect is not effective (has clouded), and its magnitude is expressed by a positive value.

Similarly, from blue photosensitive layer to red photosensitive layer, from green photosensitive layer to blue photosensitive layer, from green photosensitive layer to red photosensitive layer, from red photosensitive layer to blue photosensitive layer, from red photosensitive layer to green photosensitive layer. The interlayer effect on the conductive layer was determined for Samples 101-119.

The above values are shown in Table 1.

Next, samples 101 to 119 were used to photograph Macbeth charts under daylight tungsten light and a fluorescent lamp under the same conditions.

Hand-baked prints were performed so that the negatives from which this Macbeth chart was photographed were matched with gray on a color paper (Fuji Color Paper AGL # 653-258), and 18 colors of the resulting prints were U * V * W * color specifications. This is represented by the system (note below). To express how much each of these points deviates from the original chromaticity point of the Macbeth chart, the average color difference Δ ▲ ▼ defined by the following equation was calculated.

The results are shown in Table 2.

In order to evaluate the color reproducibility of a silver halide light-sensitive material, a method is often employed in which a color sample is actually photographed and the difference between the color on a color photographic paper obtained by printing is examined. As a color sample, a color checker (Color-Cheker) manufactured by Macbeth, Inc. in the United States is mentioned as a representative one, and it remains when the white, gray and black contained therein are reproduced on color photographic paper. Whether or not the 18 colored patches can be accurately reproduced on the color photographic paper is subjected to a sensory test or a device measurement to quantitatively evaluate. A quantitative test method for this color difference is, for example, a table calculated from the tristimulus values obtained by instrumentally measuring both colors of a sample photograph and a reproduction print by Yoshinobu Naya, "Industrial Colorology" Asakura Shoten. Various color values and color difference formulas have been proposed by many researchers.

In the present invention, David Eastwood (David
Farwood Magazine, Vol. 24, No. 1, 97
The color reproducibility was fixedly tested by the color difference formula proposed in the papers published below.

The gray gradation on the paper was about r = 1.25.

Under each light source in Table 2 Is represented as the average color difference of the deviation from the original chromaticity point under each light source.

As is clear from Table 2, in Samples 101 to 104 of the present invention, the magnitude of the interlayer effect is outside the scope of the present invention, Sample 108.
~ 119, average color difference It can be seen that the value of is small, the color saturation is high and the color reproduction is faithful. Further, the samples 101 to 104 have a spectral sensitivity distribution outside the range of the present invention. Value is small, and there is little change in average color difference between shooting under tungsten light and fluorescent light under daylight, high color saturation and faithful color reproducibility, and there is little change in color reproducibility due to change in shooting light source. I understand. From the above, the effect of the present invention is clear.

Further, in order to confirm the universality of the present invention, a color using a pyrazoloazole coupler described in U.S. Pat. No. 3,725,067, U.S. Pat. No. 4,500,630, and European Patent 119,860A as a magenta coupler. When a similar test was conducted on paper, the characteristics of the fidelity of color reproducibility and the small change in color reproducibility when the photographing light source was changed, which are advantages of the present invention, did not change, and red, magenta,
It was revealed that the saturations of purple, blue, etc. were remarkably improved and extremely excellent color reproducibility was exhibited. When the present color paper is used, the more preferable value of the interlayer effect from the green photosensitive layer to the red photosensitive layer is as small as −0.52 ≦ (D _R / D _G ) ≦ −0.15. I found that they were out of alignment.

〔The invention's effect〕

The silver halide color photographic light-sensitive material of the present invention has excellent color reproducibility even when the color temperature of the light source changes during photography, the saturation of reproduced colors is high, and the primary colors and intermediate colors are faithfully reproduced. Reproduce.
