The photographic characteristics having the high sensitivity are stably obtd. even if the replenishing amt. of the developer is decreased in such a manner.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a method for processing silver halide photographic light-sensitive materials, and in particular, the present invention relates to a method for processing silver halide photographic light-sensitive materials, and in particular, a Dry to D method that achieves high sensitivity and little change in gradation even when the amount of developer replenishment is reduced.
The present invention relates to a method for processing a silver halide photographic material having suitability for ultra-rapid processing with ry of 50 seconds or less.

0002

[Prior Art] In recent years, high-temperature, rapid processing has rapidly become popular in the development process of photographic light-sensitive materials (hereinafter referred to as "sensitive materials"), and the processing time for processing various types of light-sensitive materials with automatic processors has been significantly shortened. It's here. In order to achieve rapid processing, it is necessary to have excellent development progress to achieve sufficient sensitivity in a short period of time, and the property of drying in a short period of time after washing with water. Furthermore, in recent years, global environmental pollution has been taken up as a global issue, and interest in waste has increased both domestically and internationally, and the responsibility of companies has begun to be questioned. Under these circumstances, reducing photographic processing waste has become an urgent issue.

Regarding photosensitive materials that can be rapidly processed, Japanese Patent Application Nos. 2-48481, 2-88827, and 2-251
No. 191, No. 2-118044, etc. Attempts have also been made to reduce the volume of the replenisher container and the total amount of waste by reducing the amount of replenishment required.

0004

[Problems to be Solved by the Invention] However, if the amount of replenishment of the developer is reduced, the developer becomes fatigued more quickly, which deteriorates the progress of development.
0 seconds). Therefore, an object of the present invention is to provide a method for processing a silver halide photographic light-sensitive material that can stably obtain high-sensitivity photographic characteristics even when the amount of developer replenishment is reduced. Another object is to provide a processing method that requires only a small amount of replenishment and can stably obtain high-sensitivity photographic characteristics even in ultra-quick processing.

[0005]

[Means for Solving the Problems] An object of the present invention is to provide a silver halide photographic light-sensitive material containing selenium-sensitized silver halide grains with a grain density of 0.10 to 0.25 per m2 of the light-sensitive material.
This was achieved by a method for processing silver halide photographic materials, which is characterized by processing with a replenishment amount of developer of 1 liter. In the light-sensitive material of the present invention, at least one photosensitive silver halide emulsion layer may be provided on one side of the support, or at least one photosensitive silver halide emulsion layer may be provided on both sides of the support. The light-sensitive material of the present invention may have a hydrophilic colloid layer in addition to the light-sensitive silver halide emulsion layer, if necessary, and is preferably provided with a protective layer, for example. The light-sensitive material of the present invention has a gelatin content of 1.7 on the side having the hydrophilic colloid layer containing the photosensitive silver halide emulsion layer.
~2.7 g/m2. If the light-sensitive emulsion layer is present on only one side of the support, the amount of gelatin on that side must be within the above range, and if the light-sensitive emulsion layer is present on both sides of the support, the amount of gelatin on that side must be within the above range. It is necessary that the amount of gelatin is within the above range. When there is no hydrophilic colloid layer other than the photosensitive emulsion layer, the amount of gelatin in the photosensitive emulsion layer is within the above range. The amount of gelatin is more preferably in the range of 1.8 to 2.4 g/m2, particularly in the range of 1.9 g/m2 to
A range of 2.3 g/m2 is preferred. The melting time of the photosensitive material of the present invention is preferably set to 8 minutes or more and 45 minutes or less. Melting time as used in the present invention refers to the melting time of a silver halide photographic light-sensitive material cut into 1 cm x 2 cm pieces when the silver halide photographic light-sensitive material is immersed in a 1.5% by weight aqueous solution of sodium hydroxide at 50°C. The time required for at least one silver halide emulsion layer to begin to melt.

Next, the emulsion grains used in the present invention will be explained. The average particle size equivalent to a sphere with the same volume as the particles is 0.
It is preferable that it is 2 μm or more. Especially 0.5-2.0
Preferably it is μm. The narrower the particle size distribution, the better. The silver halide grains in the emulsion may have a regular crystal shape such as a cube or an octahedron, or may have an irregular crystal shape such as a spherical shape, a plate shape, a potato shape, etc. It may also consist of a mixture of particles of various crystalline forms, which may have . The silver halide that can be used in the silver halide emulsion may be any of silver bromide, silver iodobromide, silver iodochlorobromide, silver chlorobromide, silver chloride, and the like. Preferably, silver iodobromide (I=
0 to 10 mol%), silver bromide, and silver chlorobromide. The AgI distribution may be either an internal high concentration or an external high concentration.

When a monodisperse emulsion is used as an emulsion in carrying out the present invention, the rate of addition of water-soluble silver salt and water-soluble halide should be adjusted in accordance with the growth of silver halide grains in preparing the monodisperse emulsion. It is desirable to speed up the process. By increasing the addition rate, the particle size distribution can be made more monodisperse and the mixing time can be shortened, which is advantageous for industrial production. It is also preferable in that the chance of formation of structural defects inside the silver halide grains is reduced. As a method for increasing this addition rate, Japanese Patent Publication No. 48-36890, No. 5
As described in JP-A No. 2-16364 and JP-A-55-142329, the rate of addition of the aqueous silver salt solution and the aqueous silver halide solution may be increased continuously or in stages. The upper limit of the addition rate may be the flow rate just before new grains are generated, and the value depends on temperature, pH, pAg, degree of stirring, composition of silver halide grains, solubility, grain size, distance between grains, or protection. It varies depending on the type and concentration of colloid. Methods for producing monodisperse emulsions are known, for example, as described in J. P
hot. Sci. 12, 242-251 (1963)

Processing The photosensitive material described above is exposed to X-rays, and is cut into four-cut sizes (1
0 x 12 inches) 18 ml of developer per sheet (approx.
23 liters/m2), fixer 30ml per sheet
Developing was carried out while replenishing. Washing water is supplied at a flow rate of 10 liters per minute by opening a solenoid valve in synchronization with the time when the photosensitive material is being processed (approximately 1 liter/1 piece of four-cut size).
At the end of the day's work, a solenoid valve automatically opens to drain all the water from the tank. In this way, the developer,
The fixing solution was sufficiently subjected to running processing until it reached a running equilibrium composition, and the light-sensitive material was processed after reaching a running equilibrium composition (referred to as Processing I).

[0078] Also, the amount of developer replenishment per four-cut size sheet is 40 ml (approximately 0.52 liters/m2), and the amount of fixer is 3
The light-sensitive material was processed after sufficient running processing was carried out until a running equilibrium composition was obtained (referred to as processing II).

Evaluation of photographic performance Each of the prepared samples was
0.0 from both sides using Ray Orthoscreen HR-4.
The sensitivity was evaluated by giving exposure for 0.05 seconds. The sensitivity is based on the case where photographic material 1 is processed with processing I, and the density is 1.0.
It was determined by the reciprocal of the ratio of exposure doses that gives . The results are shown in Table 4.

[0080]

[Table 4]

As can be seen from the above results, the selenium-sensitized photographic material of the present invention has a high development activity and exhibits a small decrease in sensitivity even when a small amount of running processing solution is replenished.

18ml developer per sheet, 30ml fixer per sheet
The running process was carried out sufficiently until both the developing solution and the fixing solution had a running equilibrium composition while replenishing the running equilibrium composition, and the photographic performance of the photosensitive materials 1 to 3 was determined in the running equilibrium composition state.

[0089]

[Table 5]

Sensitivity was determined by the reciprocal of the ratio of the exposure amount giving a density of 1.0 using Developer B/Photographic Material 1 as a reference. The gradation was expressed as the slope of a straight line connecting the density point of fog +0.25 and the density point of fog +2.0.

As can be seen from the results in Table 5, the selenium-sensitized emulsion was processed with developer A in which the molar ratio of 4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidone to hydroquinone was 0.05 or more. It can be seen that there is little tendency for gradation to soften when the sensor is used, and that the sensitivity is high.

[0092]

Effect of the invention: The replenishment amount of the silver halide photodeveloper containing selenium-sensitized silver halide grains is 0.10 to 0.25.
High sensitivity and stable photographic properties can be obtained by processing at a rate of liter/m2.
