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 (hereinafter also simply referred to as a light-sensitive material),
Further, it relates to a silver halide color photographic light-sensitive material having high sensitivity and excellent color reproducibility.

[0002]

2. Description of the Related Art Conventionally, conventional silver halide color photographic light-sensitive materials are exposed to light and then subjected to color development processing to react with an oxidation product of a para-phenylenediamine color developing agent and a coupler to form a dye, thereby forming a color image. Is formed.

Generally, in this photographic method, color reproduction by a subtractive color method is used to form yellow, magenta and cyan color images.

As the magenta dye-forming coupler (magenta coupler), pyrazolone type, pyrazolinobenzimidazole type, indanone type and the like are known, and various 5-pyrazolone derivatives have been widely used.

Examples of the substituent at the 3-position of the 5-pyrazolone ring of the 5-pyrazolone derivative include an alkyl group, an aryl group, an alkoxy group described in US Pat. No. 2,439,098 and 2,369,489. , The same 2,600,78
No. 8, etc., acylamino groups, 3,558,319
The ureido group described in No. is used. However, the above-mentioned couplers have low coupling activity with the oxidized product of the developing agent and it is difficult to obtain a high density magenta color image, and the secondary absorption in the blue light region of the magenta color image obtained by color development is large. There were drawbacks such as poor cutting on the long wave side of absorption.

Further, US Pat. No. 2,311,081,
The 3-anilino-5-pyrazolone type couplers described in JP-A-3,677,764, JP-A-3684,514, British Patent Nos. 956,261 and 1,173,513 and the like are
It has advantages such as high coupling activity, high color development, and small unnecessary absorption in the red light region. However, these conventionally known 3-anilino-5-pyrazolone type couplers have a main absorption in a relatively short wave, and therefore when used in a color negative silver halide photographic light sensitive material, the print color reproducibility is deteriorated.

Various investigations have been made for the purpose of improving the above-mentioned drawbacks. For example, JP-A-52-8002.
No. 7 has 1-pentahalogenophenyl-3-anilino-
5-Pyrazolone couplers have been proposed. The coupler has high coupling activity, high color development, and good spectral characteristics, but it has a drawback that the color development is deteriorated by storage in the presence of formalin gas. Further, it cannot be said that the demand for high sensitivity of the light-sensitive material is increasing year by year.

On the other hand, as a means for improving the color reproducibility and sharpness of a silver halide color photographic light-sensitive material, it is well known to use a DIR compound which reacts with an oxidant of a color developing agent to release a development inhibitor. There is. In general, a DIR compound is added to an emulsion layer to improve color reproducibility and sharpness by utilizing an inter-image effect between layers and an edge effect between layers and layers.

However, with the recent demand for higher sensitivity of silver halide color photographic light-sensitive materials, the speed of the couplers used has been increased, and the conventional DIR has a problem that it is difficult to obtain a sufficient improvement effect. .

The eighth, ninth and tenth layers M-1 of sample 101,
Samples 102 to 130 were prepared by replacing M-2 and M-3 and D-1 and D-3 of the fourth and fifth layers as shown in Tables 4 and 5.

However, when the magenta coupler is replaced, M-1 and M-2 of sample 101 or M-1, M-3 of sample 101 are used.
Each magenta coupler was replaced with ½ of the total number of moles of. When the DIR coupler is replaced, the fourth layer is replaced with the compound D-1 of the sample 101 in an equimolar amount, and the fifth layer is added with an equimolar amount of the compound D-3 of the sample 101 or a 10-fold molar amount.

[Table 5]

As can be seen from the results shown in Tables 4 and 5, only substituting the DIR coupler of the present invention for the DIR coupler of the red light-sensitive layer did not substantially increase the interlayer effect on the green light-sensitive layer. It can be seen that the sensitivity of the green photosensitive layer is lowered depending on the usage.

It is also found that the sensitivity of the layer itself is increased but the interlayer effect received from the red light-sensitive layer is remarkably reduced only by replacing the coupler of the green light-sensitive layer with the magenta coupler of the present invention.

On the other hand, it is understood that the sensitivity of the green photosensitive layer is increased and the interlayer effect from the red photosensitive layer is sufficient only when the DIR coupler of the present invention and the magenta coupler of the present invention are used in combination.

Considering that the interlayer effect does not increase even if only the DIR coupler is replaced, and the interlayer effect is extremely reduced in the conventional coupler system when only the magenta coupler is replaced, the effect of the constitution of the present invention is surprising. It should be done.

From the results shown in Tables 4 and 5, DI having a structure represented by the partial structural formula (a) as a development inhibitor releasing group was obtained.
It can be seen that the R compound is advantageous in more effectively expressing the effects of the present invention.

In the general formula [III], R ³¹ is an arylthio group, and when R ³¹ is an arylthio group, R ³² is a pentachlorophenyl group and 2,6 dichloro-
It is understood that the 4-cyanophenyl group can exert the effect of the present invention more.

Example 2 M-1, M-2 and M- of the eighth, ninth and tenth layers of Sample 101
Samples 201 to 218 were prepared by replacing D-4 of the third and thirteenth layers as shown in Table 6 below.

However, in the case of replacing the magenta coupler, as in Example 1, each magenta coupler was used in a molar number of ½ of the sum of the molar numbers of M-1, M-2 or M-1, M-3 of sample 101. Compound IV-5 was added to the same layer in an amount corresponding to 30% by weight of the replaced coupler.

When the DIR coupler was replaced, it was replaced with the compound D-4 of Sample 101 in an equimolar amount.

DIR compounds D-7 and D-8 shown below were used as comparative compounds.

Samples 201 to 21 prepared as described above
8 was exposed to light according to the performance evaluation shown below, and
The performance was evaluated by performing the same process as in.

A) Photographic sensitivity The sample was subjected to gradation exposure with white light, the logarithm of the reciprocal of the exposure amount giving the density of the minimum density +0.3 was obtained from the characteristic curve of the magenta color image, and the sample 201 was used as a reference. The difference (ΔS) was calculated. Here, the larger the value of ΔS is, the higher the sensitivity is.

B) Inter-image effect (interlayer effect) The sample was uniformly exposed with green light for 1 lux · second, and then subjected to gradation exposure with blue light for processing to obtain a yellow density of minimum density +1.0. The value obtained by subtracting the cyan density in the minimum density portion of yellow from the cyan density at the exposure amount giving the density of was evaluated as the color turbidity value (ΔDY). The smaller the value, the larger the interlayer effect and the better the color reproduction. Table 6 shows the results.

[Table 6]

From the results shown in Table 6, even when the magenta coupler of the present invention was used in the green photosensitive layer and the DIR compound of the present invention was used in the blue photosensitive layer, the sensitivity of the green photosensitive layer increased,
Moreover, it can be seen that the interlayer effect received from the other layer (blue photosensitive layer) of the green photosensitive layer itself is effective without lowering.
