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 light-sensitive material having high sensitivity, excellent graininess and sharpness, and more particularly to a color photographic light-sensitive material having high print yield and good color reproducibility. It is a thing.

[0002]

2. Description of the Related Art In recent years, the environment for removing silver halide color light-sensitive materials is changing drastically. One reason is that the demand for high sensitivity and high image quality has become stronger than ever due to the market expansion of film with lenses. There is. On the other hand, due to the market penetration of minilab processors, processing is becoming decentralized, which causes factors of destabilizing photographic quality to increase, and the quality stability desired for photosensitive materials is still stronger than before. That is, the market needs for the most basic elements of improving the function itself of the light-sensitive material such as high sensitivity and high image quality and the stability of quality against various market fluctuation factors are more important than ever.

The intention of research and development which has been actively carried out in recent years in the art is based mostly on the above market needs, and among them, many proposals have been made regarding multilayer silver halide color photographic light-sensitive materials. Came.

For example, in British Patent No. 923,045, a high-sensitivity emulsion layer and a low-sensitivity emulsion layer containing a diffusion-resistant coupler capable of coloring in substantially the same hue are separated, and the maximum color density of the high-sensitivity layer is adjusted to be low. It is disclosed that by doing so, the sensitivity can be increased without roughening the grain. However, in this method, the graininess was still unsatisfactory.

Japanese Patent Publication No. 49-15495 proposes a method of providing a medium-speed silver halide emulsion layer having a maximum color density of 0.6 or less between the high-sensitivity emulsion layer and the low-sensitivity emulsion layer. It is true that this method significantly improved the graininess in the middle density range, but the fog density became high, the sharpness in the middle density range deteriorated, and the gradation dependence in the middle density range had a large processing dependency. There was a problem with.

In European Patent Publication No. 136,603,
With the three-layer structure of the emulsion as described above, the maximum color density of the highest sensitivity layer after exposure / development processing should be kept below 0.6, and the maximum color density of the intermediate and lowest sensitivity layers should exceed 0.6. Is proposed. Certainly, the sharpness, which was one of the problems in Japanese Examined Patent Publication No. 49-15495, was improved to some extent by this method. However, even with this method, the sharpness was not yet sufficient. This is because the middle-sensitivity layer is mostly colored in the exposure area under normal shooting conditions, because the middle-sensitivity layer develops color almost entirely, and the low-sensitivity layer develops a slight amount of color. It is thought that the sharpness will deteriorate because it is close to. Regarding the processing dependence of gradation, it is difficult to match the processing dependence of the low-sensitivity layer and the intermediate-sensitivity layer and the development progress, so that the gradation linkage tends to become poor.

Further, JP-A-61-289349 discloses a light-sensitive material having a substantially three-layer structure in which the maximum color density of the high-speed emulsion layer is 0.6 or less and the maximum color density of the medium-speed emulsion layer exceeds 0.6. Further, a light-sensitive material has been proposed in which the maximum color density of the low-sensitivity emulsion layer is 0.6 or less.

Although this method surely reduces gradation fluctuation in extreme processing, the degree of improvement in graininess and sharpness is not at a satisfactory level.

Further, according to this method, the color balance is disturbed especially when the developing processing conditions are changed, which may cause a decrease in print yield and a deterioration in color reproducibility of a specific color. all right.

The density share (maximum color density) of the middle sensitive layer of the red photosensitive layer and the green photosensitive layer of the sample 101 obtained here was determined by the method described in the detailed description, and the results are shown in Table 1. .

Coupling is applied so that the density share of the layer (maximum color density) becomes the value shown in Table 1 and the gradation in the standard color development process (3 minutes 15 seconds) has linearity. Samples 102 to 105 were prepared by appropriately adjusting the amount, the grain size of silver halide and the degree of chemical sensitization.

Exposure was performed through a stair wedge for measurement, and the following standard color development processing was performed. The developed sample thus obtained was used to measure the sensitometric curve, MTF value (sharpness) at 25 cycles per mm, and RMS (granularity) with an aperture of 48μ, and the obtained results Is shown in Table 1.

[0157]

[Table 1]

In Table 1, the higher the relative sensitivity is, the better the graininess is, of course, and the higher the sharpness, the better. Therefore, the present invention practically satisfies all the characteristics. However, it was found that most of the characteristics of the comparative examples were insufficient. The following studies were conducted to clarify this point.

Furthermore, after taking a color rendition chart by Macbeth and portraits of women using Samples 101 to 105, development was carried out in the development line B in which the reference color development process and the running test were performed once. . Using the film thus obtained, each color-printed color light-sensitive material was baked and then developed to obtain a color print. Incidentally, each sample was baked so that the gray of the Macbeth chart was a constant gray. The results of visual evaluation of the color prints thus obtained are shown in Table 2.

[0160]

[Table 2]

From Tables 1 and 2, it can be seen that the present invention can almost satisfy the relationship of sensitivity, graininess, and sharpness, and also has good results in color reproducibility under the process variation condition. .

Example 2 Samples 201 to 205 shown in Table 3 were prepared in the same manner as in Example 1. Table 3 shows the results obtained by performing the same evaluation analysis as in Example 1.

[0163]

[Table 3]

Furthermore, these samples 201 to 205 were manufactured by Konica Corporation.
Using the compact cameras Z-sp80RC and Z-up28W and the single-lens reflex camera FS-1 manufactured by the same company, 100, 200, 100 respectively.
I took a picture of the scene.

These were subjected to development processing in the above-mentioned development processing B.

These negative films were subjected to print exposure using an NPS CLP-2000L printer processor manufactured by Konica Corp., and a print was obtained using a color paper processing process CPK-18 manufactured by Konica Corp. to obtain a finished print. Five panelists examined the print yield.

The results are shown in Table 4. It can be seen that the constitution of the present invention has a good relationship between sensitivity, graininess, and sharpness as in Example 1, and the print yield is not significantly reduced even when the processing conditions are changed.

[0168]

[Table 4]

Example 3 In the same manner as in Example 1, samples in which the density share of the intermediate layer between the blue-sensitive layer and the red-sensitive layer was changed were prepared.
When the same evaluation as that shown in (1) was performed, the present invention was good.

Example 4 In the same manner as in Example 2, a sample was prepared in which the density share of the intermediate layer between the blue sensitive layer and the green sensitive layer was changed, and the same evaluations as those shown in Examples 1 and 2 were made. As a result, the present invention obtained good results.

[0171]

According to the present invention, high sensitivity, good graininess and sharpness are obtained, and at the same time there is little disturbance of the color balance when the development processing conditions are changed, the print yield is improved, and the disturbance of the color balance is caused. It is possible to provide a silver halide color light-sensitive material having no deterioration in color reproducibility.
