Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION Technical Field The present invention relates to a color silver halide photographic light-sensitive material which is highly sensitive and has an excellent image %+1. For more details,
This invention relates to a photosensitive material that exhibits high sensitivity and excellent graininess. Prior Art and its Problems Conventionally, there has been a demand for vrJ photosensitive materials with high sensitivity and excellent image quality in the field of silver halide color photography/photosensitive materials (hereinafter referred to as photosensitive materials). Particularly in recent years, opportunities to take photographs under poor conditions with low light levels have increased, and as photosensitive materials have become smaller formats, high sensitivity, sharpness, graininess, and interimage effects have increased. There is a strong demand for the development of photosensitive materials with excellent image quality. However, it is difficult to achieve both higher sensitivity and improved image quality. For example, the following is known as an M configuration that is not intended to increase sensitivity. For example, red-sensitive, green-sensitive and blue-sensitive light-sensitive silver halide emulsions 7 coated on a support? In the copper layer configuration of i+i (hereinafter, the photosensitive silver halide emulsion layer is simply referred to as "emulsion layer"), the same color-sensitive emulsion layer is used for all of the photosensitive emulsion layers, including a portion of the neck.
A high-sensitivity silver halide emulsion layer (hereinafter referred to as "high-sensitivity emulsion layer") and a low-sensitivity silver halide emulsion layer (hereinafter referred to as "low-sensitivity emulsion layer") containing diffusion-resistant couplers that develop substantially the same hue as each other. Layers that are separated and stacked adjacently;
-11t formation. According to this configuration, the emulsion layer on the side closer to the support is used during development, rather than the other emulsion layer on the far side during development, because the developer is expanded (1) and comes to L7. The problem is that it takes time. In other words, in copper layers 1 and 11, it is difficult to increase the sensitivity of the green-sensitive emulsion layer 2 and the red-sensitive emulsion layer located in the lower layer (on the support side) due to the loss of exposure amount and the delay in development.
:'It is difficult to do. On the other hand, a technique for changing the stacking order of each emulsion layer is known. For example, U.S. Pat. No. 3,663,228 vs. +111
'+1j' has (a) r1@K red sensitivity, green sensitivity and -1! from the support. A configuration is described in which low-sensitivity emulsion layers of high sensitivity are coated, and high-sensitivity emulsion layers of red sensitivity, green sensitivity, and blue sensitivity are coated on 1i1++, which is far from the support, at a distance from the support. ing. Although this technology has higher sensitivity than the i = original material with a forward bending layer structure, the valley laminate unit of the emulsion layer produced in the emulsion layer has a neutral density in ND) As is clear from the fact that they are separated by a filter, increasing sensitivity is not an issue at all. Next, in U.S. Patent No. 3,658,536, the green-sensitive emulsion layer, which has a large effect on visibility, is located on the surface side far from the support. A technique has been disclosed that attempts to eliminate the exposure amount loss. However, in this layer structure, the high-sensitivity emulsion layer for the blue-sensitive emulsion layer is not mentioned at all, and the improvements in sharpness, graininess, and interimage effect are insufficient. Other techniques related to changing the layer structure are known, such as those described in Japanese Patent Application Laid-open Nos. 51-49,027 and 53-97゜424, and U.S. Patent No. 4,129,446. It is being However, although all of these have higher sensitivity than the above-mentioned 1111-layer photosensitive material,
Not only is the sensitivity of the green-sensitive and red-sensitive emulsion layers insufficient, but also the effect of improving image quality such as graininess and sharpness is insufficient. In view of such an external protrusion, the present inventors (as a prior application of this Ig) used a low-sensitivity -7\sensitive emulsion f-, t: fine-grain silver halide was added to the adjacent layer /111 According to this proposal, the sensitivity around Dmin+ (0.4 to 0.8) will be significantly improved, and the graininess will also be improved to [1].However, the sharpness ■ Purpose of the Invention The main purpose of the present invention is to provide a highly sensitive photosensitive material, which also has high image quality (graininess s). ).The purpose is to provide a photosensitive material that achieves JzV L. Specifically, 1. On each low-sensitivity layer with different color sensitivity, each high-sensitivity J-sen with different color sensitivity is provided. When the layer structure is Dmin+ (0-4

This object is achieved by the present invention.The present invention provides at least one green-sensitive silver halide emulsion layer on a support. , at least one red-sensitive silver halide emulsion layer;
In a silver halide photographic light-sensitive material having a number of blue-sensitive silver halide emulsion layers having different sensitivities, one of the plurality of blue-sensitive silver halide emulsion layers is located on the farthest side from the support. It is provided as a layer,
At least one green-sensitive silver halide emulsion layer and at least one green-sensitive silver halide emulsion layer are provided between the blue-sensitive silver halide emulsion layer and the blue-sensitive silver halide emulsion layer, which has lower sensitivity than the blue-sensitive silver halide emulsion layer. A red-sensitive halogenated steel emulsion layer is provided, and in addition, a low-sensitivity silver halide emulsion layer of 1 and 7 cm is provided, and a layer adjacent to this has a sensitizing dye. This material is a silver halide photographic material whose characteristic is that it contains fine-grain silver halide having absorbed 75t in the surface 1. Hereinafter, the specific structure of the present invention will be explained in detail. The silver halide-sensitive source material (sensitive material) of the present invention has a plurality of blue-sensitive silver halide emulsion layers having different photosensitivity.One of the blue-sensitive silver halide emulsion layers contains all halogen Among the silver oxide emulsion layers, it is provided on the side furthest from the support.This uppermost blue-sensitive layer may be divided into two layers.On the other hand, the light-sensitive material of the present invention each has at least one green-sensitive layer. and a red-sensitive emulsion layer. At least one of each of the green-sensitive and red-sensitive emulsion layers is provided below (on the support side) the uppermost blue-sensitive layer. Below at least one green-sensitive layer and one red-sensitive layer (on the support 11 (!l), a blue-sensitive silver halide emulsion layer with a lower sensitivity than the above-mentioned uppermost blue-sensitive layer is provided). This low-light-sensitivity blue-sensitive layer is also
It may be divided into layers. In this case, the uppermost blue-sensitive layer preferably has a sensitivity difference of tdo, E = 0.2 to 1.0 with respect to this low-sensitivity blue-sensitive layer. The green-sensitive layer and the red-sensitive layer interposed between the uppermost blue-sensitive layer and the low-light-sensitivity green-sensitive layer may each be separated into two layers. In this case, the green-sensitive layer is preferably located at 1+111 (upper layer) farther from the support than the red-sensitive layer. This is because the green-sensitive layer is sensitive to wavelengths that have a greater effect on visibility, so it is placed in an upper layer to reduce the influence of -)'(l scattering. , support side (lower side) from the low-sensitivity blue-sensitive layer of the upper ml
It is preferable that the green-sensitive layer and the red-sensitive layer (d) are at least one layer each.

Note that the green-sensitive layer with low r1 and light IJf and the red-sensitive layer may each be separated into 2M. Furthermore, when the above-mentioned low-sensitivity ^' sensitive layer is divided into two layers J2, the lower-sensitivity layer 1 is placed on the support side, and these two photosensitive layers are separated. A green-sensitive layer of low sensitivity and a red-sensitive layer of low sensitivity may be interposed between the sensitive emulsion layers. Furthermore, a green-sensitive layer with a relatively low sensitivity and a red-sensitive layer with a relatively low sensitivity should be provided below the low-sensitivity layer. The following is an example of the most impressive layer structure in the present invention (・), but it is not limited to these.・+3 is the blue-sensitive layer, G is the green-sensitive layer, 1% is the red-sensitive layer] ゛・Small Δ and attach it to B, G, and R and 7'j I-1, 1-1'&

However, such a non-photosensitive intermediate layer may also contain a scavenger substance that reacts with the oxidized form of the developing agent to deactivate it. The composition of silver halide in each emulsion layer is preferably silver iodobromide or silver bromide, but side group silver bromide, silver chloride iodobromide, or the like may also be used. Regarding the grain size of the silver halide grains in the emulsion layer, in each high-sensitivity layer, the presence of small grains with large light scattering should be avoided in order to reduce sharpness deterioration for the layer located on the support side. preferable. For this reason, the average grain size of the silver halide grains in each high-sensitivity layer is preferably from 0.5 to 2.5 microns, particularly from 0.7 to 2.5 microns. When the sieve photosensitive layer is divided into two layers, the layer with higher photosensitivity is made to have a thickness of 0.7 to 2.5 μm, and the 11n layer has a thickness of about 5 to 1.5 μm.

In this case, it is preferable that the emulsion be a monodisperse emulsion with a coefficient of variation σ/〒 of 0.2 or less, where 7 is the average particle diameter of the grains and σ is the standard deviation of the particle size fraction i5. In addition, there is no restriction on the crystal structure of the silver halide grains in the emulsion layer having valley color sensitivity, and both so-called core-nel type grains and non-core type grains can be used. There are no restrictions on the method of manufacturing the emulsion layer having the above-mentioned color sensitivity, and any known method can be applied.The protective colloid used may be any one such as gelatin.

On the other hand, in the case where fine-grain silver halide is contained in a layer adjacent to a low-light-sensitivity blue-sensitive layer instead of (or in addition to this), the adjacent layer refers to a low-light-sensitivity blue-sensitive emulsion layer. It refers to the upper and lower two layers counting from the top and bottom. In this case, when the low-light sensitivity blue-sensitive layer is separated by other layers, at least one of them is divided. It is fine if there is one, but it is preferable that it is at least a blue-sensitive J- located on the upper layer side.In such a case, the adjacent layer is particularly,

In addition to the sensitization of +o, ■), Dmin +(0,4 to 0.8
), and a highly sensitive photosensitive material can be obtained. Furthermore, the linearity of gradation is also extremely good. This is probably because development inhibitory substances such as halogens that diffuse from the upper layer side during development are captured by the fine grain silver halide, reducing the inhibitory effect. Furthermore, unlike in the case of other layer configurations, the presence of fine grain silver halide significantly improves graininess, which is an effect that could not previously be expected. In the present invention, compared to the previous proposal, Dm
The sensitivity and graininess of in + (0,4-0,8) are maintained at the same level, and the sharpness is greatly improved. This effect is thought to be due to the filter effect of the blue-sensitive sensitizing dye adsorbed on the fine grain silver halide.

-8 was added at 600 .mu.m per moleK of silver halide, and 5.eta./drrI' was added to each layer. Each of the samples 1 to 8 prepared in this way was exposed to wedge light using blue light, green light, and red light, and then subjected to the following treatment. Processing process [Processing water temperature: 38°C] Processing time The composition of the processing liquid used in the can processing process was as follows. [Color developing solution] [Bleaching solution] [Fixing solution] [Stabilizing solution] The obtained S] sensitivity, S2 sensitivity, It, and MS are shown in Table 2. In this case, SI sensitivity and S2 sensitivity are expressed as the reciprocal of the exposure amount that gives a density of Dmin + 0.1 and Dmin + 0.5, respectively, relative to the sample AI VC, when the minimum density is Dmin. It is something that Also, RMS is a measure of graininess h Dm+n +
0.1 is the standard deviation of density value fluctuations that occur when scanning with a microdensitometer with a scanning aperture of 25 μ; the smaller this value is, the better the graininess is. Table 2VC shows these values for blue light (B), green light (G), and red light (R,), respectively. Furthermore, M T I' (modulation Tr
unc-1ion) was calculated, and the value when the spatial frequency was 30 cyc Ie/ma was calculated. The larger this value is, the better the sharpness is. From the results shown in Table 2, the sensitivity of the present invention material (sample A3-8
) It can be seen that extremely good values are obtained for VC8t, 82, RMS, and MTF. In particular, it can be seen that sample AIO using a monodispersed emulsion has a particularly large improvement effect. Applicant Konishiroku Photo Industry Co., Ltd. Agent Patent Attorney Yo Ishii −
