Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the processing power U of silver halide photographic materials,
More specifically, the present invention relates to a method for processing a silver halide photographic light-sensitive material spectrally sensitized in the red region, which has high image quality, improved white charcoal, good storage stability, and little residual color even when subjected to ultra-rapid processing.

[Conventional technology]

A so-called scanner is one of the exposure methods for photographic light-sensitive materials, in which an original image is scanned, and the silver halide photographic light-sensitive material is exposed to light based on the image signal to form a negative or positive image corresponding to the image on the original image. One type of image forming method is known, but as a recording light source in this method,
Semiconductor lasers, He-Me lasers, argon lasers, and LEDs are used.

In silver halide photographic materials, photographic emulsion layers or other materials are often colored for the purpose of absorbing light in a specific wavelength range.

When it is necessary to control the spectral composition of light incident on a photograph, a colored layer is provided on the photographic light-sensitive material on the side farther from the support than the photographic emulsion layer. Such a colored layer is called a filter calendar. When there are a plurality of photographic emulsion layers, such as in a color light-sensitive material, the filter layer may be located between them.

It is based on the fact that the light that is scattered when passing through the photographic emulsion layer or after being transmitted is reflected at the interface between the emulsion layer and the support or the surface of the light-sensitive material on the opposite side of the emulsion layer and enters the photographic emulsion layer again. For the purpose of preventing image blurring, that is, halation, a colored layer is provided between the photographic emulsion layer and the support, or on the opposite side of the support from the photographic emulsion layer. Such a colored layer is called an antihalation layer. ! In the case of i-calendar color photosensitive materials, an antihalation layer may be placed between each layer. Furthermore, the photographic emulsion layer may be colored in order to prevent image blurring or irradiation caused by scattering of incident light in the photographic emulsion layer.

To date, many efforts have been made and a large number of dyes have been proposed with the aim of finding dyes that satisfy the above conditions. ? 4. For example, oquin/ole dyes described in U.S. Pat. , merocyanine dyes as represented by US Pat. No. 2,493,747, and cyanine dyes as represented by US Pat. No. 2,843,48111. However, the reality is that there are very few good dyes that satisfy all of the above conditions and can be used in silver halide photographic materials. It is also a well known technique to apply optical brighteners to enhance the whiteness of silver halide photographic papers after processing.

The use of oil-soluble optical brighteners as optical brighteners is superior to water-soluble optical brighteners in that the optical brighteners are less likely to flow out during development.

As a technique for adding an oil-soluble optical brightener to a light-sensitive material, for example, British Patent No. 1. Q72,915, JP-A-45-3
As described in No. 7376 and JP-A No. 80-134232, a method is known in which an oil-soluble optical brightener is dissolved in an organic solvent and added to the photosensitive material.

However, when oil-soluble optical brighteners are applied to silver halide photographic paper that is spectrally sensitized in the red region and contains certain dyes that absorb in the red region, sensitivity decreases when exposed to high temperatures. That is, it has been found that there is a problem of deterioration of sensitivity stability or storage stability.

Therefore, it is desired to develop a dye that can be used in photographic paper that has high image quality, improved white charcoal, and excellent sensitivity storage stability (sometimes referred to simply as storage stability).

On the other hand, the consumption of silver halide photographic materials has been increasing steadily in recent years. For this reason, the number of silver halide photographic materials to be processed has increased, and there is a demand for speeding up the development process, that is, increasing the amount of processing within the same amount of time. This trend can also be seen in the printing plate making field. In other words, as the immediacy and number of times information is rapidly increasing, it has become necessary to shorten delivery times and handle larger quantities of printing plate-making operations. In order to meet such demands of the printing plate making industry, it is necessary to promote the simplification of the printing process and to process photosensitive materials for printing plate making more rapidly.

However, when ultra-rapid processing is applied to silver halide photographic paper that is spectrally sensitized in the red region and contains oil-soluble optical brighteners and conventional dyes, there is a problem that residual color or residual color unevenness tends to occur. This has been newly discovered.

[Problem to be solved by the invention]

Therefore, the purpose of the present invention is to provide a product that is spectrally sensitized to the red region with improved whitening at high image quality, excellent sensitivity storage stability, and less residual color or residual color unevenness even during ultra-rapid processing.

Those described in No. 4933 may also be used.

In the present invention, "development time" and "constant solidification time" respectively mean
The time from when the photosensitive material to be processed is immersed in the developing tank solution of the automatic processing machine until it is immersed in the next fixing solution, and from the time it is immersed in the fixing tank solution until it is immersed in the next washing tank solution (stable tank solution) "Washing time" refers to the time during which the product is immersed in the water washing tank solution, and "drying time" refers to the time during which the product is immersed in the washing tank solution.The "drying time" refers to the time during which the product is blown with hot air, usually at a temperature of 35°C to 100°C, preferably 40°C to 80°C. The drying zone is installed in the automatic processing machine, and refers to the time the machine is in that drying zone.

The development temperature and time are preferably about 25°C to 50°C and 15 seconds or less, more preferably 30°C to 40°C and 6 seconds to 15 seconds.

Next, the fixing solution is an aqueous solution containing Chizai sulfate and has a pH of 3.8.
The above is preferable, and the pH is more preferably 4.2 to 5.5.

Examples of the fixing agent include sodium thiosulfate and ammonium chizae sulfate, but these contain thiosulfate ions and ammonium ions as essential components, and ammonium chizae sulfate is particularly preferred from the viewpoint of fixing speed.The amount of the fixing agent used is determined as appropriate. generally from about 0.1 to about 6 mol/! ;L
It is.

The fixer may also contain water-soluble aluminum salts that act as hardeners, such as aluminum chloride, ammonium sulfate, potassium alum, and the like.

In the fixing solution, tartaric acid, citric acid, or their salts can be used alone or in combination of two or more. Those containing 0.005 mol or more of these compounds per liter of fixer are effective, especially 0.01 mol/l to 0.03 mol/l.
is valid. Specific examples include tartaric acid, potassium tartrate, sodium tartrate, potassium sodium tartrate, citric acid, sodium citrate, potassium citrate, lithium citrate, and ammonium citrate.

The fixing solution may contain preservatives (e.g. sulfite, bisulfite), pH! l buffering agent (e.g. acetic acid, nitric acid)
, a pH adjuster (for example, sulfuric acid), a chelating agent capable of softening water, and a compound described in Japanese Patent Application No. 80-213582.

The fixing temperature and time are preferably 3 seconds to 30 seconds at about 0°C to about 50°C, more preferably 6 seconds to 30 seconds at 30°C to 40°C, and still more preferably 6 seconds to 30°C to 40°C. It is 15 seconds.

When the fixer concentrate is refilled in the automatic processing machine in the method of the present invention with water to dilute it as the photosensitive material is processed, it is most preferred that the fixer concentrate is composed of one part. The same is true for developer.

The fixer stock solution can exist stably as a single agent at pH 4,
5 or more, more preferably pH 4.85 or more. If p)+ is less than 4.5, especially if the fixer is left for a long period of time until it is actually used, the 1,000 sulfur salt will decompose and eventually become sulfurized. Therefore the pH
In the range of 4.5 or more, less sulfur dioxide gas is generated and the working environment is improved. The upper limit of pH is not so strict, but if fixation is carried out at too high a pH, the pH of the membrane will be high even after subsequent washing with water, and membrane swelling will increase, resulting in a heavy drying load, so the upper limit is around pH 7. Fixing solutions that harden films using aluminum salts have a pH limit of 5.5 to prevent precipitation of aluminum bovine salts.

In the present invention, either the developing solution or the fixing solution may be a so-called working solution that does not require dilution water as described above (that is, it is replenished as an undiluted solution).

The amount of each concentrate supplied to the processing tank liquid and the mixing ratio with dilution water can be varied depending on the composition of the concentrate, but generally the ratio of concentrate to dilution water is 1:0 to 8. The total amount of each of these developer and fixing solutions is 1
It is preferable that it is 50m to 1500cm for rn'.

In the present invention, the photosensitive material is subjected to water washing or stabilization treatment after being developed and fixed.

Any method known in the art can be applied to the washing or stabilization treatment, and water containing various additives known in the art can also be used as the washing water or stabilizing liquid. By using anti-mold water for submerging or stabilizing liquid, it is not only possible to save water by reducing the amount of replenishment to less than 3 times per 1 m' of photosensitive material, but also eliminates the need for piping for installing an automatic processing machine. This makes it possible to further reduce the number of stock tanks. That is, the solution dilution water and washing water or stabilizing solution for the developer and fixer can be supplied from a common single-layer stock tank, making it possible to further downsize the automatic developing machine.

If anti-mildew water is used in conjunction with the washing water or stabilizing liquid, the formation of limescale etc. can be effectively prevented.
O~31, preferably 0~1, water saving treatment can be performed per n'.

Here, when the replenishment amount is O, there is no replenishment at all except for appropriately replenishing the amount of washing water in the washing tank that has decreased due to natural evaporation, etc. In other words, the so-called "reservoir water" is essentially not refilled. Refers to cases in which a processing method is used.

As a method of reducing the amount of replenishment, a multistage countercurrent system (for example, two stages, three stages, etc.) has been known for a long time. If this multi-stage countercurrent method is applied to the present invention, the photosensitive material in the fixer will be processed in a progressively cleaner direction, that is, in sequential contact with the processing solution that is not contaminated with the fixer, resulting in even more efficient processing. Washing is done. According to this, unstable thiosulfates and the like are appropriately removed, the possibility of discoloration and fading is further reduced, and an even more significant stabilizing effect can be obtained. The amount of water submerged is also much smaller compared to conventional methods.

When washing with a small amount of water, Patent Application 1728/1986
It is more preferable to provide a squeeze roller cleaning tank as described in No. 68.

In addition, part or all of the O-he-flow liquid from the washing or stabilizing bath, which is generated by replenishing the washing or stabilizing bath with water treated with anti-mold means, is disclosed in Japanese Patent Application Laid-Open No. 60-23
As described in Japanese Patent Application No. 5133, it can also be used in a processing liquid having a fixing ability, which is a processing step before that. This is more preferable because the stock water can be saved and the amount of waste liquid can be reduced.

Anti-mildew methods include the ultraviolet irradiation method described in JP-A No. 80-283!339, the method using a magnetic field described in JP-A No. 60-283!340, and the ion exchange method described in MS+-1314132. Method of purifying water using resin, #Gan Sho 80-253807, F10-295894,

In addition, ammonium chloride,
