Abstract

PURPOSE:To obtain a superior bleach-fix processing method for a photosensitive material high in sensitivity by incorporating specified silver halide grains in a layer nearest to the antihalation layer of photographic constituent layers, specifying the total thickness of the constituent layers, and using a bleaching agent contg. peroxide at the time of development processing. CONSTITUTION:The photographic constituent layers formed on a support comprise the antihalation layer contg. black colloidal silver, and blue-sensitive, green-sensitive, and red-sensitive silver halide emulsion layers, and silver halide grains contg. silver iodide are contained in the silver halide emulsion layer nearest to the antihalation layer, and the total thickness of the photographic constituent layers of the color photographic material is regulated to <=25mum. This photosensitive material is imagewise exposed, developed, and processed with a processing solution capable of bleaching silver contg. peroxide as a bleaching agent, thus permitting bleach fixing to be extremely accelerated by reducing the thickness to less than the specified thickness, and the process to be freed of toxicity by the use of peroxides, and prevented from enrivonmental pollution.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to the processing of silver halide color photographic light-sensitive materials (hereinafter referred to as color light-sensitive materials), and more specifically, the present invention relates to processing of silver halide color photographic light-sensitive materials (hereinafter referred to as color light-sensitive materials), and more specifically, the present invention relates to processing of silver halide color photographic light-sensitive materials (hereinafter referred to as color light-sensitive materials). The present invention relates to a processing method of processing with a processing solution containing a peroxide after processing with a color developing solution.

[Prior art]

Conventionally, the following methods have been generally used to process color photosensitive materials. After the color photosensitive material is subjected to imagewise exposure, it is treated with a color developing solution containing an aromatic primary amine developing agent, whereby the silver halide is reduced to metallic silver, and the aromatic primary amine is It is oxidized and undergoes a coupling reaction with a coupler to produce a dye image.

The metallic silver is oxidized to soluble silver halide by a bleaching agent (oxidizing agent) in a bleaching process. Thereafter, by treatment with a fixing solution (eg, thiosulfate, thiocyanate, etc.), the silver complex ions are converted into silver complex ions and removed from the photographic material, leaving only the color image. The actual development process involves not only the above-mentioned color development process and the basic processes of bleaching and fixing processes, but also auxiliary processes for physical photographic image preservation and quality preservation. There is also a method of processing with a bleach-fix solution that performs bleaching and fixing steps in one bath.

As the bleaching agent used in the bleaching process, red blood salt, ferric chloride, amide 7 polycarboxylic acid-metal complex salt, and peroxide are generally used.

Both red blood salt and ferric chloride have strong bleaching power, and the bleaching speed (
It is a good bleaching agent because it has a fast oxidation rate.

However, since bleaching solutions using red blood salt liberate cyanide ions through photolysis and cause environmental pollution, it is necessary to detoxify the treated waste liquid. In addition, bleaching solutions using ferric chloride have a very low pH and extremely high oxidizing power, so the processing machine equipment that contains them is easily corroded, and the emulsion layer is damaged during the water washing process after bleaching. It has the disadvantage that iron hydroxide is precipitated in it, causing so-called stain.

For this reason, a cleaning process using an organic chelating agent is required after bleaching, which is not suitable for the purpose of speeding up processing and saving labor.
Also, it emits chlorine gas, which is also an issue of environmental pollution! N ′°′”′°°′″”L<ftrs.

However, the bleaching solution of the +□ Ft acid-metal complex salt has a small acid north and an insufficient bleaching blade. For example, when bleaching a low-sensitivity color light-sensitive material based on a silver bromide emulsion, it is possible to achieve the desired purpose, but it is A high-sensitivity color photosensitive material containing silver oxide or silver iodobromide as a main ingredient and color sensitized: □Special I silver amount 2. 5, photosensitive material, '11Z * ＋ ＋.

Bleaching agents (oxidizing agents) such as polycarboxylic acid metal complex salts have problems such as environmental pollution due to the pollution load of the waste liquid, so the treated waste liquid must be completely removed. Measures must be taken to render the product harmless, and methods using peroxides that do not use metal ions, specifically persulfate ions and/or
Alternatively, it is preferable to use hydrogen peroxide or a compound that releases hydrogen peroxide. Peroxide used as a bleaching agent decomposes into water and oxygen or sulfate, which increases the biological oxygen demand (B
It is advantageous in terms of pollution control because it does not increase OD ) or chemical oxygen demand (COD ), but for example, persulfate ions have less oxidizing power than the red blood salts, ferric chloride, and metal complex salts of organic acids. It is strong and has a high redox potential, but the silver bleaching blade is weak and it takes a long time to bleach it. For this purpose, it is known to use various bleach accelerators in combination, and these bleach accelerators are added to a solution containing persulfate ions or to a prebath prior to a bleach bath, for example, as described in US Pat.

It has recently been developed as a silver halide emulsion that meets the requirements for source protection by making it chemofertile and making effective use of silver.

,, There is a core-shell emulsion that has been developed, but this core-shell emulsion, Yl 11 agent, uses the preceding silver halide emulsion as a crystal nucleus, and successively stacks subsequent precipitates on top of it, and intentionally changes the composition or environment of each precipitate. It is a monodisperse core-shell emulsion made by controlling the Among these, the core-shell type high-sensitivity emulsion containing silver iodide in the core and/or shell has extremely favorable photographic performance, but when applied to color photosensitive materials in conventional bleach-fixing baths, It was found that the bleach-fixing properties of developed silver and silver halide were extremely poor.

That is, developed silver of a photographic silver halide emulsion containing 3 mol % or more of silver iodide, especially a core-shell emulsion, containing silver iodide in the core and/or shell, and having a shell thickness of 0.
．． Developed silver with silver halide grains of 5 μm or less has excellent sensitivity, granularity, covering power, etc., but in color photosensitive materials that require bleaching, bleaching is required because the form of developed silver is different from conventional ones. In particular, it has been found that it is extremely difficult to use a bleaching solution or a bleach-fixing solution using a conventionally known ferric complex salt of ethylenediaminetetraacetic acid or ferric nitrilotriacetic acid as a bleaching agent. Similarly, fi-kaimei 5 is used as an emulsion to improve the conventional drawbacks.

Techniques using tabular halogenated grains have been developed, such as those described in US Pat.

With this technology of tabular silver halide grains, even if the number of photons lf captured by silver halide grains increases, the amount of silver used does not increase, and image quality does not deteriorate. however,
Even with these tabular silver halide grains, developed silver formed by development with a p-phenylenenoamine color developing agent has a drawback that silver bleaching properties are poor. Therefore, it is possible to quickly bleach and fix a color light-sensitive material that is a core-shell emulsion and/or a tabular silver halide emulsion containing silver iodide, which is an excellent emulsion as described above, and has an antihalation layer made of black colloidal silver. The emergence of a treatment solution is strongly desired.

[Purpose of the invention]

Accordingly, a first object of the present invention is to provide an excellent bleach-fixing method for high-sensitivity silver iodide-containing color light-sensitive materials in the processing of color light-sensitive materials.

A second object is to provide a method for processing color photosensitive materials that has a low risk of environmental pollution and meets the requirements for pollution prevention.

[Structure of the invention]

As a result of extensive research, the present inventor has found that the present inventor has a photographic constituent layer on a support including an antihalation layer containing black colloidal silver and a blue-sensitive, green-sensitive, and red-sensitive silver halide emulsion layer. The layer closest to the antihalation layer among the silver emulsion layers contains silver halide grains containing silver iodide,
And the total thickness of the photographic constituent layers is 25μ! It has been found that the objects of the present invention can be achieved by developing a color light-sensitive material having a silver density of n or less after imagewise exposure, and processing it with a processing solution containing peroxide as a bleaching agent and having a silver bleaching ability. .

Here, the photographic constituent layer refers to all the hydrophilic layers involved in image formation that are on the same side as the support surface coated with the black colloidal silver-containing antihalation layer of the present invention and the silver halide emulsion layer of at least 3Wi. In addition to the antihalation layer and the silver halide emulsion layer, it includes, for example, a subbing layer, an intermediate layer, an 1ift (mere intermediate layer, a single filter layer, an ultraviolet absorbing layer, etc.), a protective layer, etc.

The most preferred embodiment of the present invention is the general formula CI] to [

Note that the compound represented by the above general formula includes enolized compounds and salts thereof.

That is, the present inventor has prepared a silver halide emulsion of at least 3M having black colloidal silver as an antihalation layer and containing a silver iodide-containing emulsion in an adjacent layer.

When treated with a processing solution that has bleaching ability, the desilvering properties become worse when buried.
+'''11.16 Iodine silver-containing 7'-Sensitive material 0 Photograph; When the constituent layers become thinner than a certain value, the bleach-fixing property improves and desilvering defects are improved. This is what we discovered.

Furthermore, this phenomenon is caused by /, ζ of color photosensitive materials containing silver iodide.
As the film thickness of the photographic constituent layer increases, black colloidal silver becomes 6! It has been found that the desilvering defects occur at the boundary between the silver iodide-containing antihalation layer and the silver halide emulsion layer and the silver iodide-containing silver halide emulsion layer.

Furthermore, the present inventor has proposed that when a specific bleaching accelerator is added to a bleach-fix solution using peroxide as a bleaching agent, a silver colloid-containing resin-inhibiting layer and a silver denride emulsion;
Film thickness of photographic constituent layers including layers (gelatin film thickness)
A specific bleaching accelerator will not produce a good bleaching accelerating effect if the value exceeds Te, but if the thickness of the photographic constituent layer (gelatin film thickness) of a color photosensitive material is below a certain value, the bleaching accelerating effect of the specific bleaching accelerator will be improved. We have discovered the surprising fact that this can be steadily promoted.

According to a preferred embodiment of the present invention, the thickness of the photographic constituent layer of the color photographic light-sensitive material is 22 μm or less, more preferably 20 μm or less, particularly 18 μτ or less. It has been found that the object of the present invention can be achieved more effectively by this.

Furthermore, in the most effective embodiment, the above-mentioned object of the present invention can be most effectively achieved by a processing method in which a fixing process is performed after the color development process and as a preprocessing step of the bleach-fixing process. I found it. Hereinafter, this fixing process will be referred to as pre-fixing process or pre-fixing, and the processing liquid used in the pre-fixing process will be referred to as pre-fixing process liquid or pre-fixer, or pre-fixing process liquid or pre-fixing solution.

The bleaching accelerator of the present invention only needs to be present when bleaching the silver image obtained by development, and is preferably added to a processing bath having bleaching ability, and is preferably added to a processing bath having bleaching ability. It is also preferable to add the compound to the pretreatment solution and bring it into the bleach-fixing bath by bringing it into the color photosensitive material.

In the processing method of the present invention, the present invention is applied immediately after color development.5. ．． Although bright bleaching is a preferred treatment method, the bleaching treatment of the present invention may be performed after color development, washing with water, rinsing, stopping, or other treatments.

The method of the present invention includes independent steps of development, bleaching, and bleach-fixing, but here, development means black-and-white development and color development, and a method including only color development or a method including both black-and-white development and color development is also used. 1 will be given.

The above steps do not necessarily have to be consecutive, and various processing steps can be included before and after each of the above steps. Such a process is called an auxiliary process, and the auxiliary process includes a stop bath,
There are stop and fix baths, hardening baths, neutralization towers, water washing, rinsing, image stabilization baths, etc.

From the viewpoint of simplifying the processing steps, the bleaching solution or bleach-fixing solution according to the present invention is preferably applied to a processing process in which both color development and development are combined with bleaching or bleach-fixing. However, in some cases, it is more preferable that the bleach-fix solution of the present invention does not contain a developing agent or halogen ions, and depending on the type of color photosensitive material to be processed and other requirements, water washing, rinsing, and stopping may be required after color development. Processing, bleach-fixing treatment, and pre-bleach-fixing bath (so-called foundation for efficiently performing bleach-fixing)

The thickness of the photographic constituent layers (gelatin film thickness) of the color light-sensitive material of the present invention refers to the photographic constituent layers excluding the support, that is, the subbing layer, the antihalation layer, the intermediate layer, at least three emulsion layers, one filter layer, and the protective layer. This is the total thickness of all hydrophilic colloid layers, such as a layer, and the thickness of a dried photographic constituent layer. The thickness is measured with a micrometer, and in the present invention the total thickness of the photographic constituent layers is 25 .mu.m or less, preferably 22 .mu.m or less, particularly preferably 20 .mu.m or less, and most preferably 18 .mu.m or less.

The silver halide of the silver halide emulsion layer used in the present invention contains at least 0.5 mol% of silver iodide grains, but it maximizes the sensitivity and photographic properties of the color light-sensitive material and the bleach-fixing performance of the present invention. From the viewpoint of photographic properties and bleach-fixing properties, the amount of silver iodide is preferably 3 mol % to 25 mol %. In the present invention, if the content exceeds 25 mol %, the photographic properties are more favorable, but the bleach-fixing properties are significantly reduced. In the present invention, it is more preferable that silver iodide be contained in an amount of 3 mol % to 20 mol %.

The antihalation black colloidal silver dispersion layer used in the present invention has a sufficiently high optical density in the visible region (especially red light) for light incident from the support surface or emulsion surface of the color photosensitive material. It is necessary to have it. Further, it is necessary that the color light-sensitive material has a sufficiently low reflectance to light incident on the emulsion surface.

From the viewpoint of reflectance and bleach-fixing properties, it is desirable that the colloidal silver particles be sufficiently fine, but since the absorption becomes yellow to yellowish brown and the optical density against red light does not increase, it is necessary to use coarse particles to some extent. For this reason, physical development is likely to occur around these silver particles as nuclei, and it is thought that the bleach-fixability of the boundary with the silver halide emulsion layer deteriorates. Bleach-fixability is particularly important when the silver halide emulsion layer contains at least 3 mol % of silver iodide grains, especially when the silver halide emulsion layer closest to the support contains at least 3 mol % of silver iodide grains. It can be seen that the method of the present invention is effective because the phenomenon in which the chromatographic ratio decreases becomes remarkable, and the phenomenon of turbulence is noticeable in multilayer color light-sensitive materials having three or more silver iodide-containing emulsion layers.

Regarding some core-shell emulsions used in the present invention,
As described in detail in JP-A No. 57-154232, etc., a preferred color photographic light-sensitive material has a core silver halide composition of 0.1 to 20 mol % of silver iodide, preferably 0.5 mol %.
The shell is composed of silver bromide, silver chloride, silver iodobromide, silver chlorobromide, or a mixture thereof.

Particularly preferably, the shell is a silver halide emulsion comprising silver iodobromide or silver bromide. Further, in the present invention, preferable effects can be obtained by forming the core as a substantially monodisperse silver halide grain and setting the shell thickness to 0.01 to 0.5 μm.

The color photosensitive material of the present invention is characterized in that at least 3 mol%
It consists of silver halide grains containing silver iodide, has an antihalation layer made of black colloidal silver as the bottom layer, and has a film thickness (gelatin film w-) of the photographic constituent layers excluding the support of 25 μm. [Less than n. In particular, silver halide grains containing silver iodide in the core and/or shell are used, and silver halide grains consisting of silver bromide, silver chloride, silver chlorobromide, silver iodobromide, or a mixture thereof are used in the above-mentioned specific method. By hiding the core with a thick shell, the ability of silver halide grains containing silver iodide to increase sensitivity can be utilized and the disadvantageous qualities of the grains can be hidden.

A silver halide emulsion having silver halide grains having a shell of a specific thickness can be produced by coating these shells with silver halide grains contained in a monodisperse emulsion as a core.

In addition, when the shell is silver iodobromide, the ratio of silver iodide to silver bromide is preferably 20 mol % or less.

In order to make the core a monodisperse silver halide grain, (yAg
Particles of a desired size can be obtained by the double et method while keeping the value constant. Further, a highly monodisperse silver halide emulsion can be produced by applying the method described in JP-A-54-48521. A preferred embodiment of the method is a method in which a potassium iodobromide-gelatin aqueous solution and an ammoniacal silver nitrate aqueous solution are added to a gelatin aqueous solution containing silver halide seed particles while changing the addition rate as a function of time. It is to manufacture. At this time, the time function of addition rate, pH 11)A
By appropriately selecting E+, temperature, etc., a highly monodisperse silver halide emulsion can be obtained.

Since the particle size distribution of a monodisperse emulsion is almost a normal distribution, the standard deviation can be easily determined. From this, if we define the width of the distribution (%) using the relational expression, the width of the distribution that can meaningfully regulate the absolute thickness of the coating should preferably have a monodispersity of 20% or less, and more preferably 10%.

Monodisperse silver halide grains produced by this method had low covering power when a thick shell was produced.

It is suggested that t < 7 − "". Therefore, considering the filament form of developed silver, we reduced the thickness of the silver bromide shell on the surface while changing the average grain size of the core.

On the other hand, if the thickness of the shell is too thin, parts of the core material containing silver iodide will be exposed, and the effect of covering the surface with the shell, that is, the chemical sensitization effect, rapid development, fixing properties, etc. will be lost. be exposed. Preferably, the limit of the thickness is 0.01 μm.

Further confirmed by a highly monodisperse core with a distribution width of 10% or less, the preferred shell thickness is between 0.01 and 0.06μ.
The most preferable thickness is 0.03 μm or less.

The above-mentioned development silver filaments are sufficiently generated to improve the optical density, the high-sensitivity properties of the core are utilized to produce a sensitizing effect, and rapid development and fixing properties are achieved due to the high This is due to the shell whose thickness is regulated as described above by the dispersible core and the synergistic effect between the silver halide compositions of the core and shell.

The silver halide emulsion used in the present invention further includes a silver halide emulsion in which the core grains are substantially monodisperse silver halide grains, in which the core grains are formed. By coating the shell, a monodisperse silver halide emulsion with a substantially uniform shell thickness can be obtained. The emulsions may be used as they are, or two or more monodisperse emulsions having different average grain sizes may be blended at any time after grain formation to obtain a predetermined gradation.

The silver halide emulsion used in the present invention contains a substantially monodisperse core with a distribution width of 20% or less in a proportion equal to or higher than that of an emulsion obtained by coating a shell with a substantially monodisperse core. It is desirable that the silver halide grains of the present invention be included in all the silver halide grains.

In some cases, particularly favorable effects can be achieved.

It is particularly useful when the tabular silver halide grains are core-shell grains. In the case of core-shell particles, it is preferable that the requirements described above for the core-shell are also satisfied.

In general, tabular silver halide grains are tabular with two parallel surfaces, and therefore, "thickness" in the present invention is expressed as the distance between the two parallel surfaces constituting the tabular silver halide grain. .

In addition, "grain diameter" refers to the diameter of the projected surface of a tabular silver halide grain when observed in a direction perpendicular to the flat surface, and if it is not circular, the longest diameter is considered as the diameter of a circle.

During bleaching, 1.5 g of the exemplary compound 1ff-2 of the present invention per 1Q was added, and the bleaching time was changed to two steps of 1 minute and 3 minutes, and the amount of residual silver increased until bleaching Table 1. As is clear from the results above, in the case of multilayer color light-sensitive materials having layers containing a silver iodide core-shell emulsion and a silver iodide-containing tabular silver halide emulsion, if the film thickness of the photographic constituent layer (gelatin film thickness) is large, bleaching is not possible. It can be seen that although the fixing completion time is extremely good, it rapidly decreases as the thickness of the photographic constituent layer (gelatin film) becomes thinner, and the change is greatest at around 25 μm. Also, the effect of bleach preservatives is not effective when the thickness of the photographic constituent layer (gelatin film thickness) is large, but it has a remarkable effect when the photographic constituent layer is thin (gelatin film thickness). It can be seen that it is effective.

On the other hand, in the case of spherical silver iodobromide emulsions other than those of the present invention, almost no influence of the photographic structure N film thickness (gelatin film W-) is observed, and the bleach-fixing completion time is also found to be extremely short. It is difficult to put it into practical use as a high-sensitivity photographic material such as a high-sensitivity color light-sensitive material for photographing without an antihalation layer.

Example 2 Sample No. "J~16 (having an antihalation layer) in Example 1 was used, and 1.5 g/Q of the exemplified metal of the present invention and the comparative compound as shown in Table 2 were added to a pre-bleaching bath. As is clear from Table 2, the compounds of the present invention were treated with the compounds of the present invention in all cases compared to the compounds of the present invention. Samples with film thicknesses within this range showed more favorable bleaching properties (desilvering properties).In addition, the accelerator used was U--, which is a compound of the present invention.

It can be seen that even if the amount increases, the bleaching property hardly deteriorates.
