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 drying properties after washing with water and excellent in rapid processing suitability.

[0002]

2. Description of the Related Art Rapid development processing, for example, after inserting the leading edge of a film into an automatic developing machine, the leading edge of the film passes through a developing tank, a transition portion, a fixing tank, a transition portion, a washing tank, and a transition portion, and the film portion is dried. Means for improving the drying property of the silver halide photographic light-sensitive material and shortening the drying time when the processing time is 15 to 60 seconds and the line speed of the automatic processor is 1000 mm / min or more. Is effective. As a means for improving the drying property, there is a method of reducing the binder amount of the silver halide photographic light-sensitive material, but this method causes problems such as a decrease in mechanical strength of the silver halide photographic light-sensitive material, blackening of scratches, and generation of roller marks. .

Both the blackening of the scratches and the roller marks markedly reduce the commercial value of the silver halide photographic light-sensitive material. A silver halide photographic light-sensitive material having a silver halide emulsion layer on one side of a support (hereinafter also referred to as "single-sided photosensitive material").
In this case, the drying property is improved by removing the non-photosensitive hydrophilic colloid layer on the back surface or by using the non-photosensitive layer binder on the back surface as a hydrophobic binder. However, according to this method, the curl of the silver halide photographic light-sensitive material is significantly deteriorated, and a conveyance failure occurs in an automatic conveyance system, which cannot be put to practical use.

On the other hand, in many fields from the viewpoint of environmental protection,
Resources, generated gas, wastewater, waste, etc. are being reviewed. In the field of photographic processing, resource conservation, reduction of wastewater,
From the standpoint of reducing the amount of containers used and the like, there is an increasing need to reduce the amount of replenishing processing solution used for processing photosensitive materials. However, significantly developing speed reducing the replenishing amount of the developer becomes slow, and since the remarkable fixer rate reducing the replenishing amount of the fixing solution is slow, quite conventionally large amount (photosensitive material 1 m ² per developer 250 ~ 500ml, fixer is 500 ~ 800m
l) is being replenished. In order to increase the development speed and the fixing speed, the processing temperature is raised and the stirring conditions during the processing are strengthened, but there are various problems such as the generation of odor and the increase of the apparatus cost. As described above, a silver halide photographic light-sensitive material having rapid processing suitability and capable of reducing the replenishment amount of the processing solution is strongly desired.

Recently, Japanese Patent Laid-Open Nos. 5-127282 and 5-12782
No. 127306 discloses a technique of coating a hydrophilic colloid layer and a hydrophobic polymer layer in this order on the surface of the support opposite to the surface on which the silver halide emulsion layer is coated,
It has become known as a powerful means for imparting rapid processing suitability. However, as a result of studying these, the treatment liquid blocking property of the hydrophobic polymer layer in these inventions is not very large, and when it is attempted to achieve high rapid treatment suitability and reduction of the treatment liquid replenishment amount,
Further, a film-forming polymer material having excellent treatment liquid blocking property is required.

More specifically, the treatment liquid blocking property can be evaluated by the total swelling degree of the hydrophilic colloid layer and the hydrophobic polymer layer. If the processing liquid blocking property is poor, for example, the developer may carry over from the developing tank to the fixing tank (carry over), and low replenishment cannot be performed. In addition, the drying property is deteriorated and rapid treatment cannot be performed. Furthermore, even after the processing, the humidity in the air is not sufficiently cut off, curling occurs, and distortion such as a fine line image occurs.

The content of the above polymer in the hydrophobic polymer layer of the present invention is preferably 30 wt% or more, more preferably 50 wt% or more.

In addition, 1m ^{2 of} sensitive material
The coating amount of the above polymer is preferably 0.01 to 10 g, more preferably 0.1 to 3 g. With such a coating amount, the effect of the present invention is improved. On the other hand, when the coating amount is small, the present invention is not effective, and when the coating amount is too large, the hydrophobic polymer layer becomes thick and the photosensitive material is apt to curl.

In the hydrophobic polymer layer of the present invention, a matting agent, a surfactant, a dye, a slip agent, a crosslinking agent, and
Photographic additives such as thickeners, UV absorbers and inorganic fine particles such as colloidal silica may be added. Regarding these additives, for example, the description of Research Disclosure Vol. 176, Item 17643 (December 1978) can be referred to.

The hydrophobic polymer layer of the present invention may be one layer or two or more layers. There is no particular limitation on the thickness of the hydrophobic polymer layer of the present invention. However, if the thickness of the hydrophobic polymer layer is too small, the water resistance of the hydrophobic polymer layer becomes insufficient, and the back layer swells in the treatment liquid, which is inappropriate. On the other hand, if the thickness of the hydrophobic polymer layer is too large, the water vapor permeability of the hydrophobic polymer layer will be insufficient, and the moisture absorption / desorption of the hydrophilic colloid layer of the back layer will be inhibited, causing a large curl in the photosensitive material. I will end up. Of course, the thickness of the hydrophobic polymer layer also depends on the physical properties of the binder used. Therefore, it is necessary to determine the thickness of the hydrophobic polymer layer in consideration of both of them. The preferred thickness of the hydrophobic polymer layer depends on the binder species of the hydrophobic polymer layer, but it is 0.05 to 10 μm, more preferably 0.1 to 5 μm.
It is in the μm range. The hydrophobic polymer layer of the present invention is 2
When it is composed of more than one layer, the sum of the thicknesses of all the hydrophobic polymer layers is the thickness of the polymer layer of the silver halide photographic light-sensitive material of the present invention.

The method for applying the hydrophobic polymer layer of the present invention is not particularly limited. After coating and drying the back layer, the hydrophobic polymer layer may be coated on the back layer and then dried, or the back layer and the hydrophobic polymer layer may be coated simultaneously and then dried.

The back layer to which the hydrophobic polymer layer is applied in the present invention is a layer using a hydrophilic colloid as a binder, which will be described below. From the viewpoint of curling, it is preferable that the hydrophilic colloid used for the back layer has a moisture absorption rate and a moisture absorption rate that are close to those of the binder of the photographic layer on which the silver halide emulsion layer is coated. The most preferred hydrophilic colloid used as the binder in 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, and any of those commonly used in the art can be used. Among these gelatins, lime-treated gelatin and acid-treated gelatin are most preferably used. Colloidal albumin as a hydrophilic colloid other than gelatin,
Examples include proteins such as casein, agar, sugar alginates, sugar derivatives such as starch derivatives, cellulose compounds such as carboxymethyl cellulose and hydroxymethyl cellulose, and synthetic hydrophilic polymers such as polyvinyl alcohol, poly-N-vinylpyrrolidone, and polyacrylamide. You can In the case of a synthetic hydrophilic polymer, other components may be copolymerized, but when the amount of the hydrophobic copolymerization component is too large, the moisture absorption amount and moisture absorption rate of the back layer become small, which is unsuitable from the viewpoint of curling. . These hydrophilic colloids are
They may be used alone or as a mixture 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.

The back layer of the present invention may be one layer or two or more layers. Further, the thickness of the back layer of the present invention is not particularly limited, and it depends on the type of the photographic light-sensitive material to be applied, but from the viewpoint of curling, it is desirable to correspond to or be close to the thickness on the side of the photosensitive silver halide emulsion layer, Generally, it is preferably 0.2 to 20 μm, and 0.5 to 20 μm.
More preferably, it is 10 μm. When the back layer is composed of two or more layers, the sum of the thicknesses of all the back layers is 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 needs to be substantially water resistant by coating a layer outside the back layer with a hydrophobic polymer layer. “Substantially water resistant” means, in the present invention, when the back layer and the hydrophobic polymer layer are laminated, the total after immersing in water at 38 ° C. for 1 minute with respect to the total thickness of the back layer and the hydrophobic polymer layer. It means that the thickness is 1.5 times or less of the total thickness before immersion. The total thickness after immersion is preferably 1.45 times or less. In the present invention, the increase in thickness (swelling thickness) after immersion in water is 2 μm or less, and preferably 1.5 μm or less.

The method of applying the back layer of the present invention is not particularly limited. Conventionally, a known method for coating a hydrophilic colloid layer of a silver halide photographic light-sensitive material can be used. For example, a dip coating method, an air knife coating method, a curtain coating method, a roller coating method, a wire bar coating method, a gravure coating method, or an extrusion coating method using a hopper described in US Pat. No. 2,681,294, or US Pat. No. 2,761,418.
Nos. 3,508,947 and 2,761,791 can be used.
