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 a photographic fixing agent, and more particularly, in processing by an automatic processor, even when the replenishing amount of the fixing solution is reduced, fixing loss, drying property and hardness The present invention relates to a silver halide photographic light-sensitive material having excellent film properties and a processing method thereof.

[0002]

BACKGROUND OF THE INVENTION Conventionally, when a silver halide photographic light-sensitive material is processed by an automatic processor or the like, depending on its processing area,
Developer and fixer are being replenished successively. The reduction of the replenishment amounts of the developing solution and the fixing solution is desired for the following reasons.

First, there is a reduction in the cost of the treating agent when a large number of films are treated, and secondly, the cost of treating the waste liquid of the treating agent.

In particular, the second waste liquid treatment has been emphasized in recent years particularly as environmental problems have been highlighted, and has become a serious problem including transportation costs.

However, when the replenishment amount of the developing solution is actually reduced, the photographic performance is deteriorated such as a decrease in the sensitivity of the film and the deterioration of sharpness. Deteriorated, and it was difficult to reduce the replenishment amount as it was.

[0006]

SUMMARY OF THE INVENTION With respect to the above problems, the object of the present invention is to provide photographic properties such as sensitivity and sharpness, fixing transparency, drying property,
It is an object of the present invention to provide a silver halide photographic light-sensitive material capable of reducing the replenishment amount of a developing solution and a fixing solution without deteriorating the basic performance of the light-sensitive material processing such as film hardening property, and a processing method thereof.

[0007]

The above object of the present invention is to provide a silver halide photographic light-sensitive material having at least one light-sensitive silver halide emulsion layer on a support and a backing layer on the other side. Halogenated, wherein the amount of gelatin binder on the side having the silver emulsion layer is in the range of 0.5 to 3.5 g / m ² and at least one layer on the side having the silver halide emulsion layer contains a latex polymer stabilized with gelatin. This is achieved by a processing method of a silver halide photographic light-sensitive material, which comprises processing the silver photographic light-sensitive material at a replenishing rate of a fixing solution of 400 cc / m ² or less.

It is a preferred embodiment of the present invention that the silver halide photographic light-sensitive material is treated with a fixing solution having the following composition.

Thiosulfuric acid concentration ≦ 1.3 mol / liter Sulfurous acid concentration ≦ 0.06 mol / liter pH ≧ 4.35 Water-soluble aluminum salt (as Al) ≧ 0.03 mol / liter Acetate ion concentration ≧ 0.2 mol / liter The following specifically describes the present invention. explain.

In the present invention, the object of the present invention can be achieved by using a latex stabilized with gelatin.

That is, the usual latex is dispersed in water by a surfactant, but the latex which can be used in the present invention is characterized in that the surface and / or the inside of the polymer latex is dispersed and stabilized by gelatin. And The polymer constituting the latex and gelatin may have some kind of bond. in this case,
The polymer and gelatin may be directly bound or may be bound via a crosslinking agent. Therefore, the monomers constituting the latex include carboxyl group, amino group,
It is desirable to include those having a reactive group such as an amide group, an epoxy group, a hydroxyl group, an aldehyde group, an oxazoline group, an ether group, an ester group, a methylol group, a cyano group, an acetyl group and an unsaturated carbon bond. When a cross-linking agent is used, those used as a cross-linking agent for ordinary gelatin can be used. For example, aldehyde system,
A cross-linking agent such as glycol-based, triazine-based, epoxy-based, vinyl sulfone-based, oxazoline-based, methacrylic-based, acrylic-based or the like can be used.

The gelatin-stabilized latex of the invention is characterized in that at least part of the polymerisation reaction is carried out in a solvent which contains at least gelatin. USP 5026632 has a prepolymerized Tg of 25
A technique for improving pressure resistance by adding particles having a hard shell of gelatin hardened with a cross-linking agent in a layer to polymer particles having a temperature of not higher than 0 ° C. is disclosed. See also USP4920004
No. 4,855,219 also discloses a technique of improving adhesiveness by using a prepolymerized polymer particle covalently bound to gelatin as a matting agent. However, in such particles, the effect of preventing silver sludge, which is the object of the present invention, could not be recognized.

US Pat. No. 2,852,382 describes that a polymer is synthesized in the presence of gelatin, but it is intended to be contained in a silver halide emulsion layer of a color photographic light-sensitive material, and the silver sludge preventing effect as in the present invention can be obtained. I can't.

US Pat. No. 2,787,545 discloses a method of desalting a silver halide emulsion using a graft polymer of gelatin and acrylic acid. Even if such an emulsion is used, the effect of preventing silver sludge as in the present invention can be obtained. I can't. In addition, JP-A-59-
Nos. 121327 and 62-115152 describe examples of adding latex to the non-photosensitive upper layer (protective layer), but the effect of the latex of the present invention cannot be obtained.

The present inventor has found that, in the course of continuing to study the above-mentioned problems, there is a preferable range for the ratio of the addition amount of gelatin and latex at the time of synthesis. The weight ratio of gelatin to polymer at the time of synthesis (finally obtained as latex) is preferably Gel / Poly = 1/100 to 2/1, and particularly preferably 1/50 to 1/2. The effects of the present invention give particularly preferable results when the amount of the polymer component of the latex added is 20% or more based on the gelatin in the layer to which the latex is added.

The addition amount of the polymer is 0.05-5 g / m ^2, particularly preferably 0.1~2.5g / m ^2.

The polymer latex used in the present invention can change the MFT (minimum film forming temperature) depending on the composition of the monomer, but it is particularly effective when the MFT is 60 ° C. or lower, and more preferably 50 MFT. It is below ℃.

Furthermore, the present invention has a latex particle size of 0.3 μm.
The following is preferable. It is presumed that the reason why the effect of preventing silver sludge is decreased when the particle size is large is that the packing density is decreased when the particle size is large. A particularly preferred particle size is 0.01 to 0.27 μm. Examples of the composition of the monomer of the polymer latex contained in the photographic light-sensitive material of the present invention include, for example, U.S. Pat. Nos. 2,772,166 and 3,325,286.
