Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a silver halide photosensitive material, and particularly to a silver halide multilayer color photosensitive material that has good graininess, sharpness, and latitude in strobe photography. .

[Background of the invention]

In recent years, when looking at the content of the "subject" in a photo, from the content of finished prints at color labs and various photo-related data, strobe photography has been increasing for both home photos and event photos, and the use of cameras for travel photos has also increased both domestically and internationally. Indoor use has increased, and it appears that about 60% of construction photos are taken indoors or with strobe lights. This is largely due to the widespread use of cameras with built-in strobes.

[Problem that the invention seeks to solve]

As described above, when shooting with 7 rays or strobe light, the sharpness and graininess of underexposed areas are never satisfactory, and there is a problem that the main subject is erased and the image is difficult to maintain.

Conventionally, high illuminance failure of photosensitive materials is known to be the first defect that occurs in strobe photography. For example, T. H. James is a factor that causes high illumination failure.

It is described in No. 75741, etc.

Furthermore, Japanese Patent Application Laid-Open No. 62-954 describes a technique for controlling gradation changes due to high illuminance failures in the blue-sensitive layer, green-sensitive layer and red-sensitive layer.

More specifically, a technique has been disclosed (Japanese Patent Application Laid-Open No. 1-116638) regarding gradation changes in 10-'' second and 10-'' second exposures, but this has not yet reached a satisfactory level.

Furthermore, the use of DIR to improve graininess and the use of thinner films to improve sharpness have been separately proposed, but overall they are contradictory to each other and the problem has not been solved.

[Purpose of the invention]

An object of the present invention is to provide a silver halide multilayer color light-sensitive material with good graininess, sharpness, and latitude in flash or strobe photography.

[Structure of the invention]

It is expressed as (1,/u). -0 is the illumination light flux for density measurement, and - is the transmitted light flux of the part to be measured. The geometric conditions for concentration measurement are that the illumination light flux is parallel light flux in the normal direction, and that the total light flux that is transmitted as a transmitted light flux and diffused in a half space is used.When using other measurement methods, the standard Perform correction using density pieces. Also, during measurement, the emulsion film surface shall face the light receiving device side. The density measurement is performed using Status M density of blue, green, and red, and the spectral characteristics are set to the values shown in Table 2 as the comprehensive characteristics of the light source, optical system, optical filter, and light receiving device used in the densitometer.

0,120/nm, blue slope - 0,220/nm In the layer structure, it is preferable that at least one of the red-sensitive photosensitive layer and the green-sensitive photosensitive layer consists of three emulsion layers, and these are the uppermost layer. It is more preferable that the sensitivity decreases in the order of the partial layer, the intermediate layer, and the bottom layer, and that the red-sensitive photosensitive layer and the green-sensitive photosensitive layer both consist of three emulsion partial layers.

In the emulsion layering, it is advantageous to include at least a colorless fast-reacting imaging coupler in the most sensitive top layer emulsion. In particular, it is extremely useful to include a colorless, fast-reacting yellow coupler in the uppermost emulsion layer of the light-sensitive material, such as the uppermost emulsion layer of a blue-sensitive light-sensitive layer, as it can greatly improve sharpness.

The change in gradation depends on the degree of reduction in sensitivity of silver halide grains due to high-intensity reciprocity law failure and its distribution, and also depends on the DIR
It depends on the progress of development using compounds, etc.

The change in tone is controlled by appropriately mixing silver halide emulsions that exhibit different changes in tone due to high-intensity reciprocity law failure. In particular, for high-sensitivity emulsions or high-sensitivity emulsion sublayers, it is preferable to use silver halide emulsions in which high-intensity reciprocity failure is improved and the development start point is controlled.

In the present invention, the silver halide emulsion used is one that has been subjected to physical ripening, chemical ripening, and spectral sensitization. Additives used in such processes are
