Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a silver halide color photographic light-sensitive material.

(Prior Art) A method of providing a light absorption filter, a layer that absorbs light of a specific wavelength for the purpose of preventing halation or adjusting sensitivity in a silver halide photographic light-sensitive material is well known.

In particular, a yellow filter layer is placed closer to the support than the blue-sensitive layer and farther from the support than the other mezzanine layers. The method of providing an antihalation layer on the side closer to the body to prevent unnecessary light scattering is currently in general practice.

From a practical standpoint, fine particles of colloidal silver are usually used in these light absorption layers. However, these colloidal silver particles are known to cause deleterious contact fog to adjacent emulsion layers and reduce desilvering rates.

In order to improve this point, attempts have been made to use organic dyes in the filter layer instead of colloidal silver, but using these dyes speeds up the desilvering rate to some extent, but it also increases the rate of desilvering into the processing solution. The dye has poor decolorizing properties, and unnecessary absorption remains after processing, resulting in an increase in Dmin.Also, dyes are not fixed sufficiently in a specific layer and diffuse into multiple layers during storage, causing fluctuations in photographic properties. Many efforts have been made to obtain a dye that satisfies both the properties of decolorizing the dye and immobilizing it in a specific layer.

For example, US Pat. No. 2,548,564 discloses a method in which a dissociated anionic dye and a hydrophilic polymer having an opposite charge are co-existed together as a mordant, and the dye is localized in a specific layer by interaction with dye molecules. 4,124,386
No. 3,625°694, etc.

Furthermore, methods for dyeing specific layers using water-insoluble dye solids are disclosed in JP-A-56-12639, JP-A No. 55155350, JP-A No. 8B-155351, JP-A No. 63-27838, JP-A No. 63-197943, and European Patent Nos. No. 15,601, No. 274,723, No. 276.566, No. 299.4
No. 35, World Publication (WO) No. 88104794, etc. Using the dyeing methods described in these publications, it is true that dyes can be fixed in specific layers, but the ability to decolorize color light-sensitive materials to processing solutions is still insufficient. Particularly in recent years, attempts have been made to shorten the processing time, and a method for further improving decolorization has been desired.

(Problems to be Solved by the Invention) Therefore, the problems of the present invention are to use a dye that is fixed in a specific layer and has excellent decolorization properties into the processing solution, and furthermore, no unnecessary absorption remains after processing. An object of the present invention is to provide a color photographic material.

(Means for Solving the Problems) As a result of intensive research, the present inventor found that the object of the present invention can be achieved by the following means.

The color photographic photonic material according to the present invention includes the above-mentioned RD, N
α17643 pages 28-29 and companion 1i3716
615, left column to right column.

The color developing solution used in the development of the light-sensitive material of the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine color developing agent as a main component. Aminophenol compounds are also useful as color developing agents, but p-phenylenediamine compounds are preferably used, representative examples of which are 3-methyl-4-amino-N, N-diethylaniline, 3-methyl -4-amino-N-ethyl-N-
β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-β-
Examples include methoxyethylaniline and their sulfates, hydrochlorides, p-toluenesulfonates, and the like. Among these, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline sulfate is particularly preferred, and two or more of these compounds may be used in combination depending on the purpose.

The color developing solution may contain additives such as alkali metal carbonates, borates or phosphates, chloride salts, bromide salts, iodide salts, benzimidazoles, benzothiazoles or mercapto compounds. It generally contains a development inhibitor or an anti-capri agent. In addition, if necessary, various preservatives such as hydroxylamine, diethylhydroxylamine, sulfites, hydrazines such as N,N-biscarboxymethylhydrazine, phenyl semicarbazides, triethanolamine, catechol sulfonic acids, ethylene glycol, etc. , organic solvents like diethylene glycol, development accelerators like benzyl alcohol, polyethylene glycol, quaternary ammonium salts, amines, dye-forming couplers, competitive couplers,! −
Auxiliary developing agents such as phenyl-3-pyrazolidone, viscosity-imparting agents, various chelating agents such as aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, and phosphonocarboxylic acids, such as ethylenediaminetetraacetic acid, nitrile Triacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, ■-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N,N,N-trimethylenephosphonic acid, ethylenediamine-N, N, N , N-tetramethylenephosphonic acid, ethylene diamine di(0-hydroxyphenyl acetate #J), and salts thereof.

Further, when performing reversal processing, black and white development is usually performed and then color development is performed. This black and white developer contains known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as 1-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol. Alternatively, they can be used in combination.

The pH of these color developing solutions and black and white developing solutions is generally 9 to 12. The amount of replenishment of these developing solutions depends on the color photographic material to be processed, but is generally less than 31 per square meter of photosensitive material, and by reducing the bromide ion concentration in the replenisher, it can be increased to 500 or less.
It can also be less than d. When reducing the amount of replenishment, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the area of contact with the air in the processing tank.

The contact area between the photographic processing solution and air in the processing tank can be expressed by the aperture ratio defined below.

That is, the above aperture ratio is preferably 0.1 or less, more preferably 0.001 to 0.05. As a method for reducing the aperture ratio in this way, in addition to installing a shield such as a floating lid on the surface of the photographic processing liquid in the processing tank,
Method using a movable lid described in No. 033, JP-A-63
The slit development processing method described in Japanese Patent No. 216050 can be mentioned. Reducing the aperture ratio is important not only for both color development and black and white development processes, but also for subsequent processes,
For example, it is preferable to apply it to all steps such as bleaching, bleach-fixing, fixing, washing, and stabilization.Also, the amount of replenishment can be reduced by using means to suppress the accumulation of bromide ions in the developer. .

The time for color development processing is usually set between 2 and 5 minutes, but the processing time can be further shortened by using high temperature and high pi, and using a high concentration of color developing agent.

After color development, the photographic emulsion layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process (bleach-fixing process) or separately (bleach-fixing process), or in order to speed up the process, it may be carried out in two ways: bleach-fixing process after bleaching process. Depending on the purpose, treatment may be carried out in consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment. As bleaching agents, for example, compounds of polyvalent metals such as iron (fir), peracids, quinones, nitro compounds, etc. are used. Typical bleaching agents include organic complex salts of iron (III), such as ethylenediaminetetraacetic acid, Aminopolycarboxylic acids such as diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, glycol etherdiaminetetraacetic acid, or complex salts such as citric acid, tartaric acid, malic acid, etc. can be used. . Among these, ethylenediaminetetraacetic acid iron (In) complex salts and aminopolycarboxylic acid iron (I[[) complex salts, including 1,3-diaminopropanetetraacetic acid iron (I[[) m salts] require rapid processing and environmental pollution. Further, aminopolycarboxylic acid iron (I) is preferable from the viewpoint of prevention.
II) Complex salts are particularly useful both in bleach and bleach-fix solutions. These aminopolycarboxylic acid iron (I
II) 911 of a bleaching solution or a bleach-fixing solution using a complex salt is usually 4.0 to 8, but the pH can be lowered to speed up the processing.

A bleach accelerator may be used in the bleaching solution, bleach-fixing solution, and their prebaths, if necessary.

Specific examples of useful bleach accelerators are described in U.S. Pat. No. 3.893.858, German Pat.

These bleach accelerators may be added to the photosensitive material, and are particularly effective when bleach-fixing color optical materials for photography.

In addition to the above-mentioned compounds, the bleaching solution and bleach-fixing solution preferably contain an organic acid for the purpose of preventing bleach staining. Particularly preferred organic acids have an acid lysis constant (pKa) of 2.
-5, specifically acetic acid, propionic acid, etc. are preferred.

Examples of fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, thioether compounds, thioureas, and large amounts of iodide salts, but thiosulfates are commonly used. Among them, ammonium thiosulfate is the most widely used. It is also preferable to use a combination of thiosulfate, thiocyanate, thioether compounds, thiourea, etc. As a preservative for fixing solutions and bleach-fixing solutions, sulfites, bisulfites, carbonyl bisulfite adducts, or European patented The sulfinic acid compounds described in No. 294769A are preferred. Furthermore, various aminopolycarboxylic acids and organic phosphonic acids are preferably added to the fixing solution and bleach-fixing solution for the purpose of stabilizing the solution.

The total time of the desilvering process is preferably as short as possible without causing desilvering defects. The preferred time is 1 minute to 3 minutes, more preferably 1 minute to 2 minutes. In addition, the processing temperature is 25°C
~50''C, preferably 35°C to 45°C. In the preferred temperature range, the desilvering rate is improved and the occurrence of staining after processing is effectively prevented.

In the desilvering step, it is preferable that the stirring be as strong as possible.A specific method for strengthening the stirring is the treatment on the emulsion surface of the photosensitive material described in JP-A-62-183460 and JP-A-62-183461. There is a method of causing a liquid jet to collide with fJi, a method of increasing the stirring effect using a rotating means as described in JP-A-62-183461, and a method of moving the photosensitive material while bringing the emulsion surface into contact with a wiper blade provided in the liquid. Examples include a method in which the stirring effect is further improved by making the emulsion surface turbulent, and a method in which the circulation flow rate of the entire processing liquid is increased. Such means for improving agitation is effective for all bleaching solutions, bleach-fixing solutions, and fixing solutions. It is believed that improved stirring speeds up the supply of bleaching agent and fixing agent into the emulsion film, and as a result increases the desilvering rate. Further, the agitation improving means described above is more effective when a bleach accelerator is used, and can significantly increase the accelerating effect and eliminate the fixing inhibiting effect caused by the bleach accelerator.

The automatic developing machine used for the photosensitive material of the present invention is
No. 0-191257, No. 60-191258, No. 60
It is preferable to have a photosensitive material conveying means as described in Japanese Patent Laid-open No. 191259-1912. This effect is particularly effective in shortening the processing time in each step and reducing the amount of processing solution replenishment.

The silver halide color photographic light-sensitive material of the present invention is generally subjected to water washing and/or stabilization steps after desilvering treatment.

The amount of water used in the washing process depends on the characteristics of the photosensitive material (such as the coupler (depending on the material used), the purpose, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment method such as countercurrent, forward flow, etc.), and various other factors. It can be set in a wide range depending on the conditions.
The relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is J

-vision Engineers Volume 64, P.
248-253 (May 1955 issue).

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of water used for washing can be significantly reduced, but due to the increased residence time of water in the tank, bacteria will grow and the generated floating substances will adhere to the photosensitive material. There is a gap between the two. In the processing of the color light-sensitive material of the present invention, as a solution to this problem, the method of reducing calcium ions and magnesium ions described in JP-A No. 62-288.838 can be very effectively used. Also, JP-A-57-8.5

It is also possible to use the fungicides described in "Encyclopedia of Antibacterial and Antifungal Agents" (1986) edited by the Society of Industrial Science and Technology and the Japan Society of Antibacterial and Antifungal Agents.

The pH of the washing water in the processing of the photosensitive material of the present invention is 4 to 4.
9, preferably 5-8. The washing water temperature and washing time can be set variously depending on the characteristics of the photosensitive material, its use, etc., but in general, it is 20 seconds to 10 minutes at 15 to 45°C, preferably 30 seconds to 5 minutes at 25 to 40'C. A range is selected. Furthermore, the photosensitive material of the present invention can also be directly processed with a stabilizing solution instead of washing with water.

In such stabilization treatment, Japanese Patent Application Laid-Open No. 57-854
All known methods described in No. 3, No. 58-14834, and No. 60-220345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be performed. An example of this is a stabilization bath containing a dye stabilizer and a surfactant, which is used as a final bath for color photographic materials. Examples of the dye stabilizer that can be used include aldehydes such as formalin and glutaraldehyde, N-methylol compounds, hexamethylenetetramine, and aldehyde sulfite adducts.

Various chelating agents and antifungal agents can also be added to this stabilizing bath.

The overflow liquid resulting from the water washing and/or replenishment of the stabilizing liquid can also be reused in other processes such as the grudge removal process.

When each of the above-mentioned processing liquids is concentrated by evaporation in processing using an automatic processor or the like, it is preferable to correct the concentration by adding water.

The silver halide color light-sensitive material of the present invention may contain a color developing agent for the purpose of simplifying and speeding up processing. In order to incorporate a color developing agent, it is preferable to use various precursors of the color developing agent. U.S. Patent No. 3.342.59

Normally, the temperature is 33 to 38°C, but higher temperatures may be used to accelerate the processing and shorten the processing time. Conversely, it is possible to improve the image quality and the stability of the processing solution by lowering the temperature.
