Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material containing a compound which makes a development inhibitor residue or a bleach accelerator residue available during development processing.

2. Description of the Related Art In a subtractive color photographic light-sensitive material,
Conventionally, development inhibitor releasing couplers (DIR couplers) have been used for the purpose of improving photographic performance such as sharpness, graininess or color reproducibility. For the photographic effect of DIR couplers, see T.W. H. James Bias, "The Theor"

o. , New York) and the like. Further, in recent years, there has been a strong demand for speeding up processing of color negative photosensitive materials. The processing steps of the color photographic material can be roughly divided into a developing step and a desilvering step, but the desilvering step takes a large proportion of the total processing time, and the desilvering step is required to achieve rapid processing. Realization of speed is essential. Research Disclosure Item No. 1 is a means for achieving this. 24241
The bleaching accelerator releasing couplers (BAR couplers) described in JP-A Nos. 11-14149 and 61-201247 are being actively researched.

As the DIR coupler or the BAR coupler used in the green-sensitive emulsion layer, the one which forms a magenta dye at the same time as releasing a development inhibitor by a coupling reaction with an oxidized product of a developing agent during development, is a color of a light-sensitive material. It is preferable in terms of reproducibility and sharpness. Because it is a DIR coupler or B which forms a magenta dye in the green-sensitive emulsion layer.
The use of AR couplers allows the dyes produced from these couplers to be utilized as part of the magenta density,
Compared with the case of using a DIR or BAR coupler that does not form a magenta dye, the total amount of organic compounds such as couplers added to the green-sensitive emulsion layer can be reduced, and the effect of improving sharpness by thinning can be obtained. Is.

As a DIR coupler which produces a magenta color, a coupler having a 5-pyrazolone nucleus is well known.
The DIR coupler of the 5-pyrazolone mother nucleus had the drawback of low thermal stability. The DIR coupler is a development inhibitor having a property of strongly acting on silver halide and largely changing the performance of a light-sensitive material, so as to protect the active site thereof, directly or via a linking group at the coupling link active position of the coupler. By binding, it is designed to exist in an inactive state until development occurs. However, if the thermal stability of the DIR coupler is low, the DIR coupler will decompose when a light-sensitive material is stored for a long period of time or stored under conditions of high temperature and high humidity, and a substance that adversely affects photographic performance will be generated, which is fatal. It will result in deterioration of the typical photographic performance. Further, the DIR coupler having a pyrazoloazole mother nucleus described in JP-A-61-28947 does not have sufficient performance in terms of improvement of sharpness and graininess. The BAR coupler that develops magenta has the same problems as in the case of the DIR coupler, and further improvement has been desired.

18716, page 651, left column to right column, and the same No. Thirty
The development can be carried out by a usual method described in 7105, pages 880 to 881. The color developing solution used for the development processing of the light-sensitive material of the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine type color developing agent as a main component. Although aminophenol compounds are also useful as the color developing agent, p-phenylenediamine compounds are preferably used, and typical examples thereof include 3-methyl-4-amino-N, N-diethylaniline and 3- Methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N
Examples include -β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-β-methoxyethylaniline and their sulfates, hydrochlorides or p-toluenesulfonates. Among these, in particular,
3-Methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline sulfate is preferred. Two or more kinds of these compounds can be used in combination depending on the purpose. The color developer may be a pH buffer such as an alkali metal carbonate, borate or phosphate, a chloride salt, a bromide salt, an iodide salt, a benzimidazole, a benzothiazole or a mercapto compound. It is common to include an inhibitor or an antifoggant. Also, if necessary,

Representative examples thereof include ethylenediamine-N, N, N, N-tetramethylenephosphonic acid, ethylenediamine-di (o-hydroxyphenylacetic acid) and salts thereof.

When reversal processing is carried out, black and white development is usually carried out before color development. In this black-and-white developing solution, 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 are used alone. Alternatively, they can be used in combination. The color developing solution and the black and white developing solution generally have a pH of 9 to 12. The replenishing amount of these developing solutions depends on the color photographic light-sensitive material to be processed, but is generally 3 liters or less per 1 m 2 of the light-sensitive material, and the bromide ion concentration in the replenishing solution can be reduced to 500 It can be less than milliliters. When the replenishment amount is reduced, it is preferable to prevent the liquid evaporation and air oxidation by reducing the contact area with the air in the processing tank. The contact area between the photographic processing liquid and air in the processing tank can be represented by the aperture ratio defined below. That is, aperture ratio = [contact area between treatment liquid and air (cm ² )] ÷ [volume of treatment liquid (cm ³ )] The above aperture ratio is preferably 0.1 or less, more preferably 0. It is 001-0.05. As a method of reducing the aperture ratio in this way, in addition to providing a shield such as a floating lid on the surface of the photographic processing liquid in the processing tank, JP-A-1-82
No. 033, a method using a movable lid, JP-A-63-63
-216050 can be mentioned as a slit developing treatment method. To reduce the aperture ratio, not only the steps of color development and black and white development, but also the subsequent steps,
For example, it is preferably applied in all steps such as bleaching, bleach-fixing, fixing, washing with water, stabilization and the like. Further, the amount of replenishment can be reduced by using a means for suppressing the accumulation of bromide ions in the developing solution. The time of color development processing is usually set between 2 and 5 minutes, but by using a high temperature and high pH and using a color developing agent at a high concentration,
Furthermore, the processing time can be shortened.

The photographic emulsion layer after color development is usually bleached. The bleaching process may be performed at the same time as the fixing process (bleach-fixing process) or separately. Further, in order to speed up the processing, a processing method of bleach-fixing processing after bleaching processing may be used. Further, treatment with two continuous bleach-fixing baths, fixing treatment before the bleach-fixing treatment, or bleaching treatment after the bleach-fixing treatment can be optionally carried out. As the bleaching agent, compounds of polyvalent metals such as iron (III), peracids, quinones, nitro compounds and the like are used. A typical bleaching agent is an iron (III) complex salt,
For example, aminopolycarboxylic acids such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, glycol etherdiaminetetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc. Can be used. Of these, aminopolycarboxylic acid iron (II) complexes including ethylenediaminetetraacetic acid iron (III) complex salts and 1,3-diaminopropanetetraacetic acid iron (III) complex salts.
I) Complex salts are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Further, the aminopolycarboxylic acid iron (III) complex salt is particularly useful in both the bleaching solution and the bleach-fixing solution. The pH of a bleaching solution or a bleach-fixing solution using these aminopolycarboxylic acid iron (III) complex salts is usually 4.0 to 8, but a lower pH can be used for speeding up the processing.

If necessary, a bleaching accelerator can be used in the bleaching solution, the bleach-fixing solution and their pre-bath.
Specific examples of useful bleaching accelerators are described in the following specifications: US Pat. No. 3,893,858, West German Patents 1,290,812, 2,059,988, JP No. 53-32736, No. 53-57831, No. 53

No. 3,893,858, West German Patent No. 1,290,812, and JP-A-53-95630.
Compounds described in US Pat. Furthermore, US Pat.
The compounds described in No. 52,834 are also preferable. These bleaching accelerators may be added to the light-sensitive material. These bleaching accelerators are particularly effective when bleach-fixing a color light-sensitive material for photographing. In addition to the above compounds, the bleaching solution and the bleach-fixing solution preferably contain an organic acid for the purpose of preventing bleach stain. Particularly preferred organic acids are compounds having an acid dissociation constant (pKa) of 2 to 5, and specifically, acetic acid, propionic acid, hydroxyacetic acid and the like are preferable. Examples of the fixing agent used in the fixing solution and the bleach-fixing solution include thiosulfates, thiocyanates, thioether compounds, thioureas, and a large amount of iodide salts, but thiosulfates are generally used. In particular, ammonium thiosulfate can be used most widely. Further, the combined use of thiosulfate and thiocyanate, thioether compounds, thiourea and the like is also preferable. As a preservative for the fixing solution and the bleach-fixing solution, sulfites, bisulfites, carbonyl bisulfite adducts or sulfinic acid compounds described in European Patent 294769A are preferable. Further, various aminopolycarboxylic acids and organic phosphonic acids are preferably added to the fixing solution and the bleach-fixing solution for the purpose of stabilizing the solution. In the present invention, the fixer or the bleach-fixer has a pKa of 6.0 to adjust the pH.
It is preferable to add a compound of 9.0, preferably imidazoles such as imidazole, 1-methylimidazole, 1-ethylimidazole and 2-methylimidazole in an amount of 0.1 to 10 mol / liter.

The total time of the desilvering process is preferably as short as possible so long as no desilvering failure occurs. Preferred time is 1 to 3 minutes
Minutes, more preferably 1 minute to 2 minutes. The processing temperature is 25 ° C to 50 ° C, preferably 35 ° C to 45 ° C.
In the preferable temperature range, the desilvering rate is improved and the stain generation after the processing is effectively prevented. In the desilvering process, it is preferable that the stirring is strengthened as much as possible. As a concrete method for strengthening stirring, Japanese Patent Laid-Open No.
No. 183460, a method of impinging a jet of a processing solution on the emulsion surface of the light-sensitive material, a method of improving the stirring effect by using the rotating means of JP-A No. 62-183461, and a wiper blade provided in the solution. Examples include a method of moving the light-sensitive material while bringing the emulsion surface into contact with the emulsion surface to make the emulsion surface turbulent, thereby further improving the stirring effect, and a method of increasing the circulation flow rate of the entire processing solution. Such a stirring improving means is effective for any of the bleaching solution, the bleach-fixing solution and the fixing solution. It is considered that the improvement of the stirring speeds up the supply of the bleaching agent and the fixing agent into the emulsion film and, as a result, increases the desilvering rate. Further, the agitation improving means is more effective when a bleaching accelerator is used, and it is possible to remarkably increase the accelerating effect or eliminate the fixing inhibiting action of the bleaching accelerator. The automatic developing machine used for the light-sensitive material of the present invention is disclosed in JP-A-60-191257 and 60-19125.
It is preferable to have the photosensitive material conveying means described in No. 8 and No. 60-191259. JP-A-60-1
As described in No. 91257, such a conveying means can significantly reduce the carry-in of the treatment liquid from the front bath to the rear bath, and is highly effective in preventing the performance deterioration of the treatment liquid. Such effects are particularly effective in shortening the processing time in each step and reducing the amount of processing liquid replenishment.

The silver halide color photographic light-sensitive material of the present invention is generally washed with water and / or stabilized after the desilvering treatment. The amount of rinsing water in the rinsing process depends on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), application, and further, the rinsing water temperature, the number of rinsing tanks (number of stages), replenishment system such as countercurrent, forward flow, and other various conditions. It can be set in a wide range.
Among these, the relationship between the number of washing tanks and the amount of water in the multi-stage countercurrent system is described in the Journal of the Society
y of Motion Picture and T
elevision Engineers, Volume 64,
