Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a black-and-white silver halide photographic light-sensitive material, which is carried out by using an automatic developing machine. The present invention relates to various processing methods.

[0002]

2. Description of the Related Art A black-and-white silver halide photographic light-sensitive material is generally processed in the steps of developing, fixing, washing with water and drying after exposure. Recently, most of them are processed by using an automatic processor (hereinafter, abbreviated as an automatic processor). At that time, the processing is usually performed while replenishing a fixed amount of developing solution and fixing solution proportional to the area of the light-sensitive material. When such processing is performed, it has been desired that maintenance of the automatic developing machine be simple and stable photographic performance be obtained. Furthermore, it has been desired to reduce the required amount of liquid per unit area. In the past, it was general to replenish 250 ml or more, especially 330 ml or more of a developing solution and a fixing solution to 1 m ² of a so-called sheet-shaped photographic material such as X-ray photography or graphic arts sensitive material. However, since the photographic developing waste liquid and the fixing waste liquid have a high chemical oxygen demand (so-called COD) or a biological oxygen demand (so-called BOD), the developing waste liquid and the fixing waste liquid are chemically decomposed. It is carried out after detoxifying it by subjecting it to biological or biological treatment. A great economic burden is imposed on the treatment of these waste liquids.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a processing method in which a transmission type black-and-white silver halide photographic light-sensitive material is simply processed by using an automatic developing machine and a required developing solution and fixing solution amount per unit area is small. To provide.

[0004]

The present invention has an average particle size of 0.1 to 0.4 μm and a silver chloride content of 90 mol%.
A silver halide emulsion layer having a composition of silver chlorobromide, silver chloroiodobromide or silver chloroiodobromide is 150 μm or more,
The developing solution and the fixing solution are contained in an amount of 30 ml to 200 per 1 m ^{2 of the} photographic light-sensitive material on the transparent support having a thickness of 250 μm or less.
It was achieved by a method of processing a black-and-white silver halide photographic light-sensitive material, which is characterized in that batch processing is carried out by an automatic processor so that the ratio becomes less than or equal to ml. More preferably, the developer contains a benztriazole derivative and / or a nitroindazole compound. The fixing solution preferably contains at least 0.8 mol / liter of thiosulfate ion. The batch type processing is a method of processing a film having a certain area while circulating a developing solution and a fixing solution used in the replenishing container and the developing tank and the fixing tank in the developing machine. A simple processing method can be achieved by exchanging the tank liquid in the replenishing container and the automatic processing machine when a predetermined fixed film area is processed. It does not require a complicated mechanism for replenishing each film processing.

The silver halide grains used in the present invention are preferably those having a regular crystal such as a cube or octahedron, but are irregular (i.e., spherical or tabular).
It may have a rregular) crystal, or may have a composite form of these crystal forms. The high silver chloride content in the photographic emulsion layer of the photographic light-sensitive material used in the present invention is 9
Silver chlorobromide, silver iodochloride, silver iodochlorobromide, or silver chloride containing 0 mol% or more and 100 mol% or less (average value) of silver chloride. The silver iodide content is preferably 1 mol% or less. Particularly preferred is 96 mol% or more and 100 mol% or less (average value)
Is silver chlorobromide or silver chloride containing silver chloride. The high silver chloride emulsion used in the present invention preferably has a silver bromide localized layer in which the silver bromide content is relatively higher than that of the substrate in the silver halide grains.

A preferred example of such a localized structure is one having a localized phase on the surface of the silver halide grain or in the interior close to the surface, and particularly in the edge portion or corner portion of the crystal surface of the grain, or the crystal plane. Those having a localized phase in the form of protrusions are preferable. The halogen composition in the localized phase may have a silver bromide content of 10 mol% or more and 95 mol% or less.
It is preferably in the range of mol% to 90 mol%. Further, it is preferably 20 mol% or more and 60 mol% or less, and most preferably 30 mol% or more and 60 mol% or less. The remaining silver halide in the localized phase consists of silver chloride, but it is also preferred to include traces of silver iodide. However, as described above, it is not preferable to exceed 1 mol% with respect to the total amount of silver halide. Further, these localized phases preferably account for 0.03 mol% or more and 10 mol% or less, more preferably 0.1 mol% or more and 10 mol% or less of the silver halide constituting all the silver halide grains of the emulsion. It is preferable to occupy mol% or less.

The localized phase does not have to consist of a single halogen composition, and may have two or more localized phases having distinctly different silver bromide contents, and other than the localized phase. It may be such that the interface with the phase is formed while continuously changing the halogen composition. In order to form a silver bromide localized phase as described above, a water-soluble silver salt and a water-soluble halogen salt containing a water-soluble bromide are simultaneously mixed with an emulsion containing silver chloride or high silver chloride grains already formed. Or deposit a portion of the already formed silver chloride or high silver chloride grains into a silver bromide-rich phase using the so-called halogen conversion method, or silver chloride or high silver chloride grains. It can also be formed by adding fine grained silver bromide or high silver bromide grains or other sparingly soluble silver salt to crystallize the surface of silver chloride or high silver chloride grains by recrystallization. For such a manufacturing method,
For example, it is described in European Patent Application Publication No. 0,273,430A2.

The silver bromide content of the localized phase can be determined by the X-ray diffraction method (for example, described in “Chemical Society of Japan, New Experimental Chemistry Lecture 6, Structural Analysis” Maruzen) or XPS method (for example, “Surface analysis, −
IMA, Application of Auger electron and photoelectron spectroscopy- "Kodansha,
, Etc.) and the like. The silver bromide localized phase can also be known by electron microscope observation or the method described in the above-mentioned European Patent Application Publication No. 0,273,430A2.

Of these methods, the method of forming a high silver bromide layer particularly useful in the present invention is a method of forming silver bromide and / or silver chlorobromide on the surface of a high silver chloride emulsion during chemical ripening. And is preferable in that high sensitivity and low fog can be obtained.

The silver halide grains used in the present invention include metal ions other than silver ions (for example, metal ions of Group VIII of the periodic table, transition metal ions of Group II, lead ions of Group IV and Group I). It is preferable that the effect of the present invention be better exhibited under various conditions. The metal ions or complex ions thereof may be contained in the entire silver halide grains, the above-described silver bromide localized phase, or any other phase. Among the above metal ions or complex ions thereof, those selected from iridium ion, palladium ion, rhodium ion, zinc ion, iron ion, platinum ion, gold ion, copper ion and the like are particularly useful. It is often the case that these metal ions or complex ions are used in combination, rather than being used alone, to obtain desirable photographic properties. In particular, it is necessary to change the added ionic species and the added amount between the localized phase and other parts of the particle. Is preferred. In particular, iridium ions and rhodium ions are preferably contained in the localized phase.

In order to incorporate a metal ion or a complex ion in the localized phase of the silver halide grain and / or the other portion of the grain, the metal ion or the complex ion is formed before, during or after the formation of the silver halide grain. It may be added directly to the reaction vessel during the subsequent physical ripening, or may be added in advance in the addition solution of the water-soluble halogen salt or water-soluble silver salt. When the localized phase is formed of fine grains of silver bromide or high silver chloride, it is contained in fine grains of silver bromide or high silver chloride by the same method as described above, and then it is added to a silver chloride or high silver chloride emulsion. May be added to. In addition, a metal ion may be contained while forming a localized phase by adding a bromide other than a silver salt, which is relatively insoluble in metal ions as described above, as a solid or powder.

The size of the silver halide grains used in the present invention is not larger than 0.4 μm, preferably 0.35 μm.
m or less, more preferably 0.3 μm or less, 0.1 μm
That is all. This is desirable in that the smaller size of the particles gives a higher covering power and the silver / binder ratio can be reduced.

The size distribution of silver halide grains may be wide or narrow, but so-called monodisperse emulsions are better in terms of photographic characteristics such as latent image stability and pressure resistance and processing stability such as developer pH dependency. preferable. The value S / d obtained by dividing the standard deviation S of the diameter distribution when the projected area of silver halide grains is converted into a circle by the average diameter is preferably 20% or less, more preferably 15% or less.

That is, any of an acidic method, a neutral method, an ammonia method and the like may be used, but the acidic method and the neutral method are particularly preferable in the present invention in terms of reducing fog. To obtain a silver halide emulsion by reacting a soluble silver salt with a soluble halogen salt, any one of so-called one-side mixing method, simultaneous mixing method or a combination thereof may be used. It is also possible to use a so-called reverse mixing method in which grains are formed under the condition of excess silver ions. In order to obtain the monodisperse grain emulsion preferred in the present invention, it is preferable to use the simultaneous mixing method. As one form of the simultaneous mixing method, it is more preferable to use a method of keeping the silver ion concentration in the liquid phase where silver halide is produced constant, that is, a so-called controlled double jet method. By using this method, it is possible to obtain a silver halide emulsion suitable for the present invention, which has a regular silver halide crystal shape and a narrow grain size distribution.
