Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a photographic yellow coupler, particularly a color photographic light-sensitive material containing a yellow coupler that is advantageous for improving sharpness and increasing sensitivity.

(Prior Art) Many studies have been conducted on color photographic materials with the aim of improving sharpness and increasing sensitivity. One technique is to improve the coupler. In other words, a coupler with a high color density per unit weight is advantageous in making the layer thinner because the amount of the coupler added to the sensitive emulsion layer can be reduced accordingly. This reduces the scattering of light incident on the photosensitive layer,
Improve sharpness. Furthermore, the higher the reactivity of the coupler with respect to the oxidized developing agent, the more efficiently the oxidized developing agent can be used, which is advantageous for increasing the sensitivity of the photosensitive material.

From the viewpoint of reducing the thickness of the photosensitive layer, one known yellow coupler is, for example, the coupler described in US Pat. No. 4,248,961. These couplers could be improved to some extent for the purpose of thinning the photosensitive layer.However, the known couplers mentioned above are still insufficient in terms of color forming properties, and further improvements are desired. The current situation is that A coupler described in JP-A No. 62-218962 is known for this purpose, but it is difficult to use in general-purpose photosensitive materials because of the high cost in mass-scale production.

The present invention provides a color photographic material with high sensitivity and excellent sharpness by containing a yellow coupler that is highly reactive, has a high color density per unit weight, and can be manufactured at a reasonable manufacturing cost. It is about providing.

In addition, as necessary, hydroxylamine, diethylhydroxylamine, sulfite hydrazines, phenyl semicarbazides, triethanolamine, catechol sulfonic acids, triethylenediamine (1,4-diazabicyclo[2°2.2]octane), etc. Various preservatives, organic solvents such as ethylene glycol and diethylene glycol, development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, and amines; 1 dye-forming pullers, competitive couplers, and foggants such as sodium boron hydride; agent, auxiliary developing agent such as l-phenyl-3-pyrazolidone, viscosity imparting agent, various chelating agents such as aminopolycarboxylic acid, aminopolyphosphonic acid, alkylphosphonic acid, phosphonocarboxylic acid, etc. Ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, l-hydroxyethylidene-l, 1-diphosphonic acid, nitrilo-N,N,N-trimethylenephosphonic acid, ethylenediamine- N, N, N',
Representative examples include N'-tetramethylenephosphonic acid, ethylene glycol (0-hydroxyphenylacetic acid), 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 l-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol. It can be used alone or 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 light-sensitive material being processed, but it is generally less than 3 centimeters per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher, it can be reduced to 500 dj.
You can also do the following: 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. Furthermore, the amount of replenishment can be reduced by using means for suppressing the accumulation of bromide ions in the developer.

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

After color development, the photographic emulsion layer is usually bleached. The bleaching process may be performed simultaneously with the fixing process (bleach-fixing process), or may be performed separately. Furthermore, in order to speed up the processing, a processing method may be used in which a bleaching treatment is followed by a bleach-fixing treatment.

Furthermore, treatment with two consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment can be carried out as desired depending on the purpose. Examples of bleaching agents that can be used include compounds of polyvalent metals such as iron (■), cobalt (■), chromium (1'V), and H(n), peracids, quinones, and nitro compounds. Typical bleaching agents include ferricyanide: dichromate: iron (m
) or organic complex salts of cobalt (I [I), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1

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 (for example, depending on the materials used such as couplers), the application, the temperature of the washing water, the number of washing tanks (the number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. Can be set over a wide range. this house,
The relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is as follows:
Journal of the 5ociety of
MotionPicture and Te1evi
sion Engineers Volume 64.

It can be determined by the method described in p., 248-253 (May 1955 issue).

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of washing water can be significantly reduced, but bacteria will grow due to the increased residence time of water in the tank.

This may cause problems such as the generated floating matter adhering to the photosensitive material. In the processing of the color light-sensitive material of the present invention, as a solution to such problems, the method of reducing calcium ions and magnesium ions described in Japanese Patent Application No. 131632/1988 can be used very effectively. In addition, chlorine-based disinfectants such as isothiazolone compounds, cyabendazole, chlorinated sodium isocyanurate, and other benzotriazoles described in JP-A No. 57-8542, "Chemistry of Antibacterial and Antifungal Agents" by Hiroshi Horiguchi It is also possible to use the disinfectants described in Sanitation Techniques Complete Volume ``Sterilization of Microorganisms, Disinfection, and Spinning Machine Technology'' and ``Encyclopedia of Antibacterial and Antifungal Agents'' published by Japan Antibacterial Textile Science and Technology.

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 in various ways depending on the characteristics of the photosensitive material, its use, etc., but generally it is 20 seconds to 10 minutes at 15 to 45°C, preferably 20 seconds to 10 minutes.
A range of 30 seconds to 5 minutes is selected at 5 to 40°C. 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 Nos. 57-8543 and 58-148
All known methods described in No. 34 and No. 60-220345 can be used.

Furthermore, following the water washing process, a further stabilization process may be performed, such as a stabilizing bath containing formalin and a surfactant, which is used as a final bath for color photosensitive materials for photography. . 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 a process equivalent to the desilvering process.

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. For example, U.S. Patent No. 3,342,59

Normally, the standard temperature is 33°C to 38°C, but higher temperatures can be used to accelerate processing and shorten processing time, or lower temperatures can be used to improve image quality and stability of the processing solution. can do. Further, in order to save silver on the photosensitive material, a treatment using cobalt intensification or hydrogen peroxide intensification as described in German Patent No. 2,226,770 or US Pat. No. 3,674,499 may be carried out.

Furthermore, the silver halide photosensitive material of the present invention is disclosed in U.S. Patent No. 4,
No. 500,626, JP-A-60-133449, No. 5
