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 silver halide light-sensitive material, and more particularly to a processing method in which the stability of a developing solution is improved and contamination such as tar due to deterioration of the developing solution with time is improved. Furthermore, the present invention relates to a processing method capable of obtaining stable photographic properties in continuous processing.

2. Description of the Related Art In the color development processing of a silver halide color photographic light-sensitive material, a color developing solution containing an aromatic primary amine color developing agent has been conventionally used for forming a color image, and nowadays a color developing solution is used. It plays a central role in the method of forming photographic images. However, the color developer has a problem that it is easily oxidized by air or metal, and when a color image is formed by using the oxidized developer, the stain is increased, the sensitivity and the gradation are changed. Therefore, it is well known that desired photographic characteristics cannot be obtained.

Further, with the recent rapid processing at high temperature and the reduction of replenishment amount, the above deterioration phenomenon tends to be further accelerated. As a result, liquid fatigue due to high temperature,
Due to the low replenishment, the development solution is colored and the decomposed product of the developing agent is accumulated due to long-term retention of the processing solution in the processing tank.

Conventionally, so-called preservatives have been developed in order to prevent such deterioration of liquid. Substituted hydrazine having a substituent, for example, JP-A-63-1706
42, 63-170643, JP-A-1-9795.
3 and European Patent Application Publication Nos. 0285010 and 02
Alkyl-substituted hydrazines described in JP-A No. 54280, etc. have been studied, but they are not always sufficient, and it is difficult to suppress fatigue of the developing solution with time (for example, generation of stain).

[0005]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a developer having excellent stability and for long-term solution aging or during continuous processing of a silver halide photographic light-sensitive material.
It is an object of the present invention to provide a processing method which is less likely to deteriorate the developing agent and which is excellent in preventing the contamination of the developing solution.

The processing method of the present invention is used when continuous processing is performed using an automatic processor. The replenisher for each processing solution supplements the consumption and deterioration of processing solution components over time in the processing of photosensitive materials and in automatic developing machines, and suppresses the accumulation of unwanted components that elute from photosensitive materials in the processing solution. In order to keep the performance constant, it is preferably added depending on the amount of the processed light-sensitive material. Therefore, the former compound has a higher concentration than the tank liquid, and the latter compound has a lower concentration. Further, two or more processing baths may be provided in each processing step, and in that case, it is preferable to adopt a countercurrent system in which the replenisher is poured from the rear bath to the front bath. In particular, it is preferable to use a cascade of 2 to 4 stages in the washing process and the stabilizing process. Also,
The color developing bath may be divided into two or more baths as necessary, and the color developing replenisher may be replenished from the frontmost bath or the last bath to shorten the developing time or further reduce the replenishing amount. Further, by using a processing tank having a slit-shaped small cross-sectional area as described in JP-A-2-67556, a post-bath is provided so that the developing solution can flow in the direction opposite to the traveling direction of the photosensitive material. A method of replenishing from the near side and overflowing from the opposite side is also preferable. Conversely, the developer may be replenished so that the developing solution can flow in the same direction as the traveling direction of the photosensitive material. The replenishment amount of each processing solution is preferably reduced as long as the compositional change in each processing solution does not cause photographic performance or other inconveniences due to contamination of the solution.

The color developing replenisher contains a compound contained in the color developing solution. Compounds for compensating the consumption and deterioration of the processing solution components with the processing of the light-sensitive material and the lapse of time in the automatic processor are a color developing agent and a preservative, and the replenisher contains 1.1 to 10 parts of the tank solution. Included in 4 times the amount. Further, a compound that suppresses the accumulation of undesired components eluted from the light-sensitive material in the processing solution is a development inhibitor represented by a halide (for example, potassium bromide). 0.6 times included. The halide concentration in the replenisher is usually 0.006 mol / liter or less, but it is necessary to reduce the concentration as the replenisher is lowered, and it may not be contained at all. In addition, a compound that is unlikely to change its concentration due to processing or aging is usually contained in approximately the same concentration as the color developing tank solution. Examples of this are chelating agents and buffers. Further, the pH of the color developing replenisher is higher than that of the tank solution by about 0.1 to 1.0 in order to prevent the pH of the tank solution from being lowered by the processing. This difference in pH also needs to be increased as the amount of replenishment decreases.

The replenishing amount of the color developing solution is not more than 3000 ml per 1 m ² of the light-sensitive material, preferably 50 to 600 ml, more preferably 50 to 300 ml. The replenishing amount of the bleaching solution is 20 to 90 per 1 m ² of the light-sensitive material.

The replenishing amount of the fixing solution is ^{20 to} 1500 per 1 m ² of the light-sensitive material.
ml, preferably 30 to 600 ml, more preferably 50 to 200 ml. The replenishing amount of the washing water or the stabilizing solution is preferably 200 to 1500 ml, and more preferably 300 to 600 ml per 1 m ^{2 of the} light-sensitive material to be processed. The washing process and the stabilizing process are preferably a multi-stage countercurrent system, and the number of stages is preferably 2 to 4. The amount of replenishment is 1 to 50 times, preferably 2 to 30 times, more preferably 2 to 15 times the amount carried in from the previous bath per unit area.

Further, it is preferable to use a method in which the overflow liquid in the water washing step or the stabilizing step is caused to flow into a bath having a fixing ability as a pre-bath because the amount of waste liquid can be reduced.

When processing with the above-mentioned black-and-white developing solution or color-developing solution in an automatic developing machine, the area (opening area) in which the developing solution (color-developing solution and black-and-white developing solution) comes into contact with air should be as small as possible. preferable. For example, when the value obtained by dividing the opening area (cm ² ) by the volume of the developing solution (cm ³ ) is taken as the aperture ratio, the aperture ratio is preferably 0.01 (cm ^-1 ) or less, more preferably 0.005 or less.

In order to further reduce the amount of the replenisher solution for environmental protection, it is also preferable to use various regenerating methods in combination. Regeneration may be performed while circulating the processing solution in the automatic processor, or after removing the processing solution from the processing tank, performing appropriate recycling processing and returning it to the processing tank as a replenishing solution again. Is also good. In particular, the developer can be regenerated and used.

Since the metal chelate bleaching agent in the bleaching solution and / or the bleach-fixing solution becomes a reducing state with the bleaching treatment, the bleaching solution and / or the bleach-fixing solution should be continuously regenerated in cooperation with the treatment. It is preferable to take. In particular,
It is preferable to blow air into the bleaching solution and / or the bleach-fixing solution with an air pump to reoxidize the metal chelate in a reduced state by oxygen, so-called aeration. In addition, it can be regenerated by adding an oxidizing agent such as hydrogen peroxide, persulfate or bromate. The fixing solution and the bleach-fixing solution are regenerated by electrolytically reducing accumulated silver ions. In addition, it is also preferable to remove accumulated halogen ions with an anion exchange resin in order to maintain the fixing performance. Ion exchange or ultrafiltration is used to reduce the amount of washing water used, and it is particularly preferable to use ultrafiltration.

The silver halide color photographic light-sensitive material is generally at least on a support. At least one layer of silver halide emulsion layers of a blue-sensitive layer, a green-sensitive layer and a red-sensitive layer is provided.

Further, the installation order may be such that different color-sensitive layers are sandwiched between the same color-sensitive layers. A non-photosensitive layer such as various intermediate layers may be provided between the silver halide photosensitive layers and as the uppermost layer and the lowermost layer. For the intermediate layer, JP-A-61-43748 is used.

The silver iodochloride emulsion preferable in the present invention will be described below. In the present invention, silver iodochloride contains substantially no silver bromide. The phrase "substantially free of silver bromide" means that the molar content of silver bromide is 1 mol% or less. The case where silver bromide is not contained at all is preferable.
A preferred silver iodochloride emulsion of the present invention is a high silver chloride silver iodochloride emulsion containing at least 85 mol% of silver chloride. The molar content of silver chloride is preferably 90 mol% or more, more preferably 93 mol% or more, and particularly preferably 95 mol% or more. The silver iodide content is 0.1.
It is preferably at least mol% and at most 10 mol%, more preferably at least 0.1 mol% and at most 5 mol%. The silver halide emulsion may be an internal latent image type emulsion or a surface latent image type emulsion.

The emulsion grains may have a uniform crystal structure inside, or may have different halogen compositions inside and outside, or may have a layered structure of three or more layers. Therefore, the silver halide emulsion of the present invention can have a distribution or structure with respect to the halogen composition in its grains. A typical example thereof is a core-shell type or double structure type grain having a halogen composition in which the inside of the grain differs from the surface layer. In such particles, the shape of the core part and the entire shape with the shell may be the same or different. Specifically, the core portion has a cubic shape, and the shell-containing particles may have a cubic shape or an octahedral shape. On the contrary, the core part may be an octahedron and the particles with shell may have a cubic or octahedral shape. Further, although the core portion is a regular regular particle, the particle with shell may be slightly deformed or may have an irregular shape. In addition, it is not just a double structure, but a triple structure or more multilayer structure,
A silver halide having a different composition can be thinly applied to the surface of the double-structured grain of the shell.

In order to give a structure to the inside of the particle, not only the wrapping structure as described above but also a so-called bonded structure can be prepared. The crystal to be bonded can be generated by bonding to the edge, corner, or face of the host crystal with a composition different from that of the host crystal. In this case, the surface of the host crystal is, for example,
The halogen conversion initiation inhibitor which is an adsorbing organic compound such as mercaptoazoles, nucleic acid decomposition products, and dyes described in No. 102453 can be used. The use of this halogen conversion initiation inhibitor is also useful when performing halogen conversion on the host crystal. Such a bonded crystal has a uniform core composition even if the host crystal has a uniform halogen composition.
It can be formed even if it has a shell type structure. In the case of a junction structure, it is naturally possible to combine silver halides with each other, but a silver salt compound not having a rock salt structure such as silver rhodan and silver carbonate may be combined with silver halide to form a junction structure. Also, a non-silver salt compound such as PbO may be used as long as it can form a junction structure. The grains having these structures are, for example, core-shell type grains having a high silver iodide content in the core portion and a low silver iodide content in the shell portion, or conversely, containing silver iodide in the core portion. Particles having a low amount and a high shell portion may be used. Similarly, with respect to the grains having a junction structure, the grains having a high silver iodide content in the host crystal and having a relatively low silver iodide content in the junction crystal may be used, or vice versa. In addition, the boundary portion where the halogen composition of grains having these structures is different,
The boundary may be a clear boundary, an unclear boundary by forming a mixed crystal due to a composition difference, or a positively continuous structure change.

In the present invention, an emulsion composed of grains having any structure is preferably used rather than one having a uniform composition within the grains in terms of halogen composition. In particular, a grain having a halogen composition in which silver iodide is smaller in the grain surface than in the grain is more preferably used. A typical example thereof is a core-shell type emulsion containing a higher content of silver iodide in the core than in the shell. The constituent molar ratio of the core part and the shell part may be any ratio as long as it is between 0: 100 and 100: 0, but in order to make it distinctly different from particles having a uniform structure, it is 3: 97-98: 2. Is preferred. When the shell portion is formed by so-called halogen conversion utilizing the difference in solubility of silver halide, the core portion is not uniformly covered, but at least 98: 2 is acceptable. More preferable ratio of core to shell is 5:95 to 8
It is between 5:15, and more preferably 15: 85-7.
It is between 0:30. Although the difference in the silver iodide content between the core part and the shell part depends on the molar ratio of the core part and the shell part,
It is preferably 0.5 mol% or more. More preferably, it is 5.0 mol% or more. When the silver iodide contents in the core portion and the shell portion are not so different from each other, that is, when the composition difference is small, the grain is not so different from that of a grain having a uniform structure and the feeling is low. If the composition difference is large, desensitization or the like due to pressure is likely to occur, so it is necessary to devise a means for reducing them. The appropriate composition difference depends on the composition ratio of the core part and the shell part, and is 0:
The closer the composition ratio is to 100 or 100: 0, the larger the composition difference is, and the closer the composition ratio is, the smaller the composition difference is.

The silver iodochloride grains preferred for use in the present invention, even if they are normal crystals not containing twin planes, are described in The Photographic Society of Japan and the Basic Silver Salt Photographs in the Photographic Industry (Corona Publishing Co., p.163).

For the silver iodochloride emulsion used in the present invention, the above-described method for preparing a silver halide emulsion can be used. That is, any of an acidic method, a neutral method, an ammonia method and the like may be used, and a method of reacting a soluble silver salt and a soluble halogen salt may be a one-sided mixing method, a simultaneous mixing method or a combination thereof. Good. A method of forming grains in the presence of excess silver ions (so-called reverse mixing method) can also be used. As one form of the simultaneous mixing method, a method of keeping pAg in a liquid phase where silver halide is formed constant, that is, a so-called controlled double jet method can be used. According to this method, a silver halide emulsion having a regular crystal form and a substantially uniform grain size can be obtained.

The soluble silver salt aqueous solution or the soluble alkali halide water-soluble one or both solutions to be added are
It is also effective to prepare more than one kind and change the concentration or composition of two or more kinds of the prepared aqueous solutions, respectively, if necessary.

The method disclosed in JP-A No. 2,445, which raises the addition concentration with time is a preferable method for preparing the silver iodochloride emulsion used in the present invention. It is preferable as a method for preparing the silver iodochloride emulsion used in the present invention that a part of the grains is converted with a different anion during grain formation or at an appropriate time after grain formation. Before the desalting process, after the desalting process and before chemical aging,

You may add and heat-age it.

In the process of silver halide grain formation or physical ripening, coexistence of cadmium salt, zinc salt, lead salt, thallium salt, iridium salt or its complex salt, rhodium salt or its complex salt, iron salt or iron complex salt, etc. Good. Particularly, the iridium salt is used in an amount of 10 ^-9 to 10 ^-4 mol / mol, and more preferably 10 ^-8 to 10 ^-5 mol / mol, based on silver halide. This is particularly useful in obtaining rapid developability and stability at high illuminance or low illuminance, which is out of the proper exposure illuminance range, as compared with an emulsion prepared without using an iridium salt. Emulsions doped with a large amount of polyvalent impregnated ions as disclosed in JP-A-62-260137 are preferable for improving reciprocity law failure and can be used in the silver iodochloride emulsion of the present invention. In any case, the chloride concentration during particle formation is preferably 5 mol / liter or less, and 0.07 to 3 mol / l.
A concentration of liter is particularly preferred. The temperature during particle formation is 1
The temperature is 0 to 95 ° C, preferably 40 to 90 ° C. The pH at the time of particle formation is not particularly limited, but a neutral to weakly acidic range is preferable.

In order to satisfy the target gradation of the light-sensitive material, two or more kinds of monodisperse silver halide emulsions having different grain sizes in an emulsion layer having substantially the same color sensitivity are mixed in the same layer or different layers. Can be applied in multiple layers. Further, two or more kinds of polydisperse silver halide emulsions or a combination of monodisperse emulsions and polydisperse emulsions can be mixed or laminated and used. In the present invention, it is particularly preferable to use two or more monodisperse emulsions as a mixture or as a multilayer.
