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, and more particularly to a silver halide photographic light-sensitive material having improved dryness after development and stripping of a matting agent.

[0002]

2. Description of the Related Art Recently, it has been required to shorten the development processing time of silver halide photographic light-sensitive materials. In order to shorten the development processing time, it is effective to improve the drying property of the silver halide photographic light-sensitive material to shorten the drying time. As a means for improving the drying property, there is a method of reducing the binder amount of a silver halide photographic light-sensitive material, but this method reduces the mechanical strength of the silver halide photographic light-sensitive material, scratches blackening,
Problems such as generation of roller marks occur. Scratch blackening is a phenomenon in which, when handling a silver halide photographic light-sensitive material before development processing, when the film surface is rubbed, this portion is blackened in a scratched state after development processing. The roller mark is a phenomenon in which a fine unevenness of a roller is applied to a silver halide photographic light-sensitive material during automatic development processing, and a pressure is applied to the silver halide photographic light-sensitive material to cause black spot-like density unevenness. Both the blackening of the scratches and the roller marks markedly reduce the commercial value of the silver halide photographic light-sensitive material.

As another means of improving the drying property, it is also effective to increase the amount of the hardener added to the silver halide photographic light-sensitive material. According to this method, the swelling of the silver halide photographic light-sensitive material during development processing is reduced, so that the drying property is improved. However, with this method, problems such as desensitization due to development delay, reduction of covering power, residual silver due to fixing delay, residual color, etc. occur, and sufficient drying property cannot be improved.

In the case of a silver halide photographic light-sensitive material (hereinafter referred to as "single-sided light-sensitive material") having a silver halide emulsion layer on one side of a support, the non-light-sensitive hydrophilic colloid layer on the back surface is removed. Alternatively, by using a hydrophobic binder as the binder of the non-photosensitive layer on the back surface, the drying property is improved. However, according to this method, the curl of the silver halide photographic light-sensitive material is significantly deteriorated and it cannot be used for practical use. In order to solve such a problem, in Japanese Patent Application No. 3-145168, the support is farther from the support than the non-photosensitive hydrophilic colloid layer on the surface not having the silver halide emulsion layer (that is, the back surface). The invention was made to provide a hydrophobic polymer layer in place. According to the present invention, the drying time after the development processing can be shortened without increasing the curl of the light-sensitive material. However, it has been found that the use of a hydrophobic polymer for the outermost layer on the back surface makes it easier for the matting agent on the back surface to peel off, which becomes a white powder and stains the surface of the photosensitive material.

[0005]

SUMMARY OF THE INVENTION The first object of the present invention is to provide a silver halide photographic light-sensitive material which has a good drying property after development processing. The second object of the present invention is to provide a silver halide photographic light-sensitive material having an improved curl. A third object is to provide a silver halide photographic light-sensitive material having the above-mentioned first and second goals, in which the matting agent on the back surface does not easily come off.

[0006]

SUMMARY OF THE INVENTION The above-mentioned problem is that at least one silver halide emulsion layer having a hydrophilic colloid as a binder is provided on one surface of a support, and the silver halide emulsion layer of the support is In a silver halide photographic light-sensitive material having a non-photosensitive hydrophilic colloid layer containing a hydrophilic colloid as a binder on the surface opposite to the coated surface, the silver halide photographic light-sensitive material is provided at a position farther from the support than the non-photosensitive hydrophilic colloid layer. A non-photosensitive hydrophilic colloid layer having a hydrophobic polymer layer and / or
Alternatively, it is achieved by a silver halide photographic light-sensitive material characterized in that the hydrophobic polymer layer contains at least one matting agent represented by the following general formula (I). General formula (I)

First, the non-photosensitive hydrophilic colloid layer (hereinafter referred to as the back layer) of the present invention will be described. The back layer of the present invention is a layer using a hydrophilic colloid as a binder. As the hydrophilic colloid used for the back layer, a binder for the photographic layer coated with the silver halide emulsion layer is used from the viewpoint of curling. It is preferable that the moisture absorption rate and the moisture absorption rate are close to each other. The most preferable hydrophilic colloid used for the binder of the back layer of the present invention is gelatin. As the gelatin, so-called lime-processed gelatin, acid-processed gelatin, enzyme-processed gelatin, gelatin derivatives and modified gelatin, which are generally used in the art, can be used. Of these gelatins,

-Synthetic hydrophilic compounds such as vinylpyrrolidone and polyacrylamide can be cited. In the case of a synthetic hydrophilic compound, other components may be copolymerized, but if the amount of the hydrophobic copolymerization component is too large, the moisture absorption amount and moisture absorption rate of the back layer will be small, which is unsuitable from the viewpoint of curling. These hydrophilic colloids may be used alone or in combination of two or more.

In the back layer of the present invention, other than the binder,
A photographic additive such as a matting agent, a surfactant, a dye, a crosslinking agent, a thickener, a preservative, a UV absorber, and inorganic fine particles such as colloidal silica may be added.

[Chemical 3]

The back layer of the present invention may be one layer or two or more layers. The thickness of the back layer of the present invention is not particularly limited, but from the viewpoint of curling, it is preferably about 0.2 μ to 20 μ, and particularly preferably 0.5 μ to 10 μ. If the back layer consists of two or more layers, add the sum of the thicknesses of all back layers,
The thickness of the back layer of the silver halide photographic light-sensitive material of the present invention.

The back layer of the present invention is substantially non-swelling in the processing liquid. The term "substantially non-swelling in the processing liquid" means that the thickness of the back layer after the washing step during the development processing is 1.05 times or less the thickness of the back layer after the drying step.

Since the back layer of the present invention uses a hydrophilic colloid such as gelatin as a binder, it essentially swells in the processing liquid. However, in the present invention, a hydrophobic polymer layer (hereinafter referred to as a polymer layer) coated on this layer can be substantially non-swelled in the processing liquid.

The method for applying the back layer of the present invention is not particularly limited.

The polymer layer of the present invention may be one layer or two or more layers. The thickness of the polymer layer of the present invention is not particularly limited. However, if the thickness of the polymer layer is too small, the water resistance of the polymer layer will be insufficient and the back layer will swell in the treatment liquid, which is inappropriate. On the contrary, when the thickness of the polymer layer is too large, the water vapor permeability of the polymer layer becomes insufficient, and the moisture absorption / desorption of the hydrophilic colloid layer of the back layer is impeded, resulting in poor curling. Of course, the thickness of the polymer layer also depends on the physical properties of the binder used. Therefore, the polymer layer thickness needs to be determined in consideration of both of them. The preferable thickness of the polymer layer depends on the binder species of the polymer layer, but is 0.05 to 10 μm.
