Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a silver halide photographic light-sensitive material. In particular, the present invention relates to a silver halide photographic light-sensitive material using a silver halide emulsion which has improved fog and sensitivity change during storage.

[0002]

2. Description of the Related Art A silver halide emulsion used in a silver halide photographic light-sensitive material is usually chemically sensitized with various chemical substances in order to obtain desired sensitivity, gradation and the like. As typical methods thereof, sulfur sensitization, selenium sensitization, noble metal sensitization such as gold sensitization, reduction sensitization, and various sensitization methods using combinations thereof are known. In recent years, there has been a strong demand for high sensitivity, excellent graininess and high sharpness in silver halide photographic light-sensitive materials, and rapid processing for accelerating the progress of development.
Various improvements have been made to the above sensitization method. Among the above sensitizing methods, the selenium sensitizing method is described in US Pat. No. 1,574.

However, in general, selenium sensitization has a greater sensitizing effect than the sulfur sensitization generally performed in the art, but fog is large, and it tends to be easily softened. There are many. Although many of the above-mentioned known patents improve these drawbacks, they have still obtained insufficient results, and a basic improvement for suppressing the occurrence of fog has been eagerly desired. Also,
In particular, when gold sensitization is used in combination with sulfur sensitization and selenium sensitization, a marked increase in sensitivity can be obtained, but at the same time, fog also increases.
Compared with gold-sulfur sensitization, gold-selenium sensitization has a particularly large increase in fog, and development of technology to suppress fog generation, especially development of selenium sensitizer with little sensitivity change during storage and less fog generation. It was strongly desired.

An object of the present invention is to provide a highly sensitive silver halide photographic light-sensitive material with less fog.

Along with the sensitizing dye, a dye that does not have a spectral sensitizing effect itself or a substance that does not substantially absorb visible light and exhibits supersensitization may be included in the emulsion. For example, a substituted aminostilbenzene compound having a nitrogen-containing heterocyclic nucleus group (for example, those described in US Pat. Nos. 2,933,390 and 3,635,721), aromatic organic acid formaldehyde condensation (For example, US Pat. No. 3,743,

The light-sensitive material of the present invention comprises a coating aid, an antistatic agent,
One or more surfactants may be included for various purposes such as improving slipperiness, emulsifying and dispersing, preventing adhesion, and improving photographic characteristics (for example, development acceleration, hardening, sensitization).

The light-sensitive material produced by using the present invention may contain a water-soluble dye in a hydrophilic colloid layer as a filter dye or for various purposes such as prevention of irradiation or halation. Such dyes include oxonol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, anthraquinone dyes,

The present invention is applicable to multilayer multicolor photographic materials having at least two different spectral sensitivities on the support. Multilayer natural color photographic materials usually have at least one red-sensitive emulsion layer, one green-sensitive emulsion layer and one blue-sensitive emulsion layer on a support. The order of arrangement of these layers can be arbitrarily selected as required. The preferred layer arrangement is from the support side in the order of red-sensitive, green-sensitive and blue-sensitive, blue-sensitive layer, green-sensitive and red-sensitive layers or blue-sensitive, red-sensitive and green-sensitive. Further, an arbitrary emulsion layer having the same color sensitivity may be composed of two or more emulsion layers having different sensitivities to improve the ultimate sensitivity.
The graininess may be further improved as a three-layer structure. Further, a non-photosensitive layer may be present between two or more emulsion layers having the same color sensitivity. An emulsion layer having different color sensitivity may be inserted between certain emulsion layers having the same color sensitivity. A sensitivity layer may be improved by providing a reflective layer of fine grain silver halide under the high sensitivity layer, especially the high sensitivity blue sensitive layer. Generally, a cyan-forming coupler is contained in the red-sensitive emulsion layer, a magenta-forming coupler is contained in the green-sensitive emulsion layer, and a yellow-forming coupler is contained in the blue-sensitive emulsion layer, but different combinations can be used in some cases. For example, a combination of infrared-sensitive layers may be used for pseudo color photography or semiconductor laser exposure.
