Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic light-sensitive material having a dyed hydrophilic colloid layer. More specifically, it has absorption in the infrared region and is stable in the photographic material. The present invention relates to a silver halide photographic light-sensitive material having a hydrophilic colloid layer containing a dye which is chemically inert and is easily decolorized in the course of photographic processing.

2. Description of the Related Art In silver halide photographic light-sensitive materials, photographic emulsion layers or other layers are often colored for the purpose of absorbing light of a specific wavelength. When it is necessary to control the spectral composition of the light to be incident on the photographic emulsion layer, a coloring layer is provided on the side of the photographic photosensitive material farther from the support than the photographic emulsion layer. Such a colored layer is called a filter layer. When there are a plurality of photographic emulsion layers as in a multi-layer color light-sensitive material, the filter layer may be located between them. The light scattered during or after passing through the photographic emulsion layer is reflected at the boundary between the emulsion layer and the support or at the surface of the light-sensitive material on the side opposite to the emulsion layer and re-enters the photographic emulsion layer. For the purpose of preventing image blurring, that is, halation, a coloring layer is provided between the photographic emulsion layer and the support or on the surface opposite to the support and the photographic emulsion layer. Such a colored layer is called an antihalation layer. In the case of a multi-layer color light-sensitive material, an antihalation layer may be placed in the middle of each layer. Coloring of the photographic emulsion layer is also carried out in order to prevent a reduction in image sharpness due to light scattering in the photographic emulsion layer (this phenomenon is generally called irradiation).

These layers to be colored are often composed of hydrophilic colloids and are therefore usually used for their coloring.
A water-soluble dye is contained in the layer. This dye is required to satisfy the following conditions. (1) It has an appropriate spectral absorption according to the purpose of use. (2) Photochemically inactive. In other words, the performance of the silver halide photographic emulsion layer should not be adversely affected in a chemical sense, for example, reduction in sensitivity, latent image regression, or fogging. (3) It should not be decolorized or dissolved and removed in the course of photographic processing to leave no harmful coloring on the photographic light-sensitive material after processing. (4) Excellent stability over time in solution or photographic material.

Many dyes which absorb visible light or ultraviolet rays are known to satisfy such conditions, and for the purpose of image improvement in conventional photographic elements sensitized to these wavelengths of 700 nm or less. Suitable for In particular, triarylmethane and oxonol dyes are widely used in this context. On the other hand, recording materials sensitized to infrared wavelengths in recent years, for example, anti-halation and anti-irradiation dyes that absorb in the infrared region of the spectrum for photographic light-sensitive materials as recording materials for recording the output of near-infrared laser Development is required. For example, one of the exposure methods for such a photographic light-sensitive material is to scan the original image, and the silver halide photographic light-sensitive material is exposed on the basis of the image signal to form a negative or positive image corresponding to the image of the original image. An image forming method using a so-called scanner method is known. In this method, a semiconductor laser is most preferably used as a scanner type recording light source. This semiconductor laser is small, inexpensive, and easy to modulate, has a longer life than other He-Ne lasers, argon lasers, and emits light in the red sensitive region. When used, a bright safelight can be used, which has the advantage that handling workability is improved.

[0005]

However, since there is no suitable dye which has the absorption in the infrared region of the spectrum and satisfies the above-mentioned conditions (1), (2), (3) and (4), it is highly sensitive to the infrared region. In reality, it is impossible to make full use of the characteristics of the semiconductor laser having the excellent performance as described above, since there are few excellent photosensitive materials having properties and preventing halation and irradiation. To date, many efforts have been made to find dyes satisfying the above conditions, and a large number of dyes have been proposed. For example, Japanese Patent Laid-Open No. Sho 62

Alternatively, a non-labile selenium compound is added, and the emulsion is stirred at a high temperature, preferably 40 ° C. or higher for a certain period of time. Japanese Unexamined Patent Publication No. 41 as an unstable selenium compound

It is preferable to use the compounds described in Japanese Patent Application No. 130976 and Japanese Patent Application No. 2-229300. Specific examples of the unstable selenium sensitizer include isoselenocyanates (for example, aliphatic isoselenocyanates such as allyl isoselenocyanate), selenoureas, selenoketones, selenamides, and selenocarboxylic acids (for example, 2- Selenopropionic acid, 2-selenobutyric acid), selenoesters, diacyl selenides (for example, bis (3-chloro-2,6
-Dimethoxybenzoyl) selenide), selenophosphates, phosphine selenides, colloidal metal selenium and the like. The preferred types of labile selenium compounds are described above, but are not limiting. Stable selenium compounds as sensitizers for photographic emulsions are known to those skilled in the art, as long as selenium is unstable, the structure of the compounds is not so important, and organic compounds of selenium sensitizer molecules are not important. It is generally understood that the moieties carry selenium and play no role other than allowing it to be present in the emulsion in an unstable form. In the present invention, the labile selenium compound having such a broad concept is advantageously used. As the non-labile selenium compound used in the present invention, compounds described in JP-B-46-4553, JP-B-52-34492 and JP-B-52-34491 are used.

The sensitizing dyes described on pages 2 to 38 are preferably used.
Particularly, the dyes represented by formulas [I], [II] and [III] described in JP-A-3-171136, pages 8 to 12 are preferable. However, when these sensitizing dyes are used alone, the efficiency of spectral sensitization cannot be said to be sufficient, and the intrinsic desensitization tends to increase as the amount of addition increases. As a countermeasure against this, it is known to use a supersensitizer together, for example, Japanese Patent Publication No. 60-45414.

These sensitizing dyes may be used alone or in combination, and the combination of sensitizing dyes is often used especially for the purpose of supersensitization. Along with the sensitizing dye, a dye having no spectral sensitizing effect itself or a substance that does not substantially absorb visible light and exhibits supersensitization may be contained in the emulsion.

The content of the sensitizing dye of 600 nm or more of the present invention depends on the grain size of the silver halide emulsion, the halogen composition, the method and degree of chemical sensitization, the relationship between the layer containing the compound and the silver halide emulsion, and the antifoggant compound. It is desirable to select the optimum amount according to the type and the like, and a test method for the selection is well known to those skilled in the art. Usually, preferably 10 ^-7 to 1 × 10 ^-2 mol, particularly 10 ^-6 to 5 × 1 mol per mol of silver halide.
