Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a method for processing a silver halide color photographic material (hereinafter referred to as a color photographic processing method) for developing, bleaching and fixing an exposed silver halide color photographic material. It relates to color photographic processing methods involving bleaching action.

<Prior Art> Generally, in order to obtain a color image by developing exposed silver halide color photographic material, after the color development step, the developed silver image is bleached with an oxidizing agent (bleaching agent).
Next, a step of fixing with a fixing agent is performed. In contrast to this type of method in which bleaching and fixing are performed in separate processing steps, a method called bleach-fixing is a method that simplifies the processing steps and completes bleaching and fixing simultaneously in one step for the purpose of speeding up processing and saving labor. A processing method has been proposed.

In addition, a bleaching agent using force-fielded ferric iron has a very low pH and extremely high oxidizing power, making it convenient for bleaching, but it has the disadvantage that the parts of the processing machine that houses it are easily corroded. In addition, iron hydroxide is deposited in the emulsion layer in the washing process after bleaching, resulting in so-called staining.

Compared to these bleaching agents, organometallic complex salts such as ethylenediaminetetraacetic acid iron complex salts and persulfur M salts are less toxic and advantageous in terms of pollution control, so their use as bleaching agents has been recommended in recent years. The force is relatively small, so the bleaching blade is insufficient, and the bleaching effect is particularly high when processing high-sensitivity silver halide color photographic materials that are mainly based on silver iodobromide emulsion and color sensitized. If it is insufficient, desilvering will be poor and the bleaching or bleach-fixing efficiency will be low, making it difficult to achieve the purpose.

From the viewpoint of pollution prevention, it is desirable to use a metal complex salt of an organic acid or a persulfur M salt as a bleaching agent, but as mentioned above, this results in insufficient bleaching power, so this point should be avoided. Unless this problem is solved, it will not be possible to achieve the objective of rapidly processing high-sensitivity color photographic materials.

Conventionally, it has been proposed to add various bleaching accelerators to bleaching solutions or bleach-fixing solutions that use a metal complex salt of an organic acid such as ethylenediaminetetraacetic acid iron complex as a bleaching agent. Examples of such bleaching accelerators include thiourea derivatives as described in Japanese Patent Publication No. 45-8506, selenourea derivatives as described in Japanese Patent Publication No. 46-280, British Patent No. 1,138,
5-membered ring mercapto compounds as described in No. 842, aliphatic amines as described in Japanese Patent Publication No. 46-556, or thiourea derivatives and thiazole derivatives as described in Swiss Patent No. 336.257, There are thiadiazole derivatives, etc.

In addition, as a bleaching accelerator that increases the bleaching ability of a bleaching solution using persulfate as a bleaching agent, for example, US Patent No. 3.772,0
Amino compounds described in No. 20, No. 3.893.858 and Research, Disclosure No. 15704 are known.

However, many of these bleach accelerators do not necessarily have a satisfactory bleach accelerating effect, and even if they have an excellent bleach accelerating effect, they lack stability in the processing solution, so the effective life of the processing solution is short and long-term. Those that have the disadvantage of not being able to withstand storage, or that the bleaching accelerating effect cannot be obtained when they are included in the so-called pre-treatment solution used in the process before processing with bleach or bleach-fix solution. There are many things that we have.

A third object of the present invention is to provide a color photograph using a bleaching accelerator that can increase the bleaching rate and provide a stable processing solution when incorporated into a bleaching solution or a bleach-fixing solution. The object of the present invention is to provide a processing method.

A fourth object of the present invention is to provide a color photographic processing method using a bleaching accelerator which can increase the bleaching rate even when incorporated into a silver halide color photographic material.

The silver halide emulsion used in the photographic light-sensitive material used in the processing method of the present invention includes conventional silver halide such as silver bromide, silver iodobromide, silver iodochloride, silver chlorobromide, and silver chloride. Any of those used in silver halide emulsions can be used.

The silver halide grains used in the silver halide emulsion may be obtained by any of the acid method, neutral method, and ammonia method. The particles may be grown all at once, or may be grown after seed particles are created. The method of creating and growing the seed particles may be the same or different.

In the silver halide emulsion, halide ions and silver ions may be mixed simultaneously, or one may be mixed in a liquid in which the other is present. Alternatively, while considering the critical growth rate of silver halide crystals, halide ions and silver ions may be generated by sequentially and simultaneously adding them while controlling pH 11)A(+) in a mixing pot.By this method, , silver halide grains having a regular crystal shape and a nearly uniform grain size can be obtained.After growth, a conversion method may be used to change the halogen composition of the grains.

During the process of grain formation and/or growth, silver halide grains are produced using cadmium salts, zinc salts, lead salts, thallium salts, iridium salts (including complex salts), rhodium salts (including complex salts), and iron salts ( (including complex salts) to add metal ions to the inside of the particles and/or
Alternatively, these metal elements can be contained on the particle surface, and reduction sensitizing nuclei can be provided inside the particle and/or on the particle surface by placing the particle in an appropriate reducing atmosphere.

Unnecessary soluble salts may be removed from the silver halide emulsion after the growth of silver halide grains is completed, or they may be left contained.

The silver halide grains may be such that the latent image is mainly formed on the surface, or may be such that the latent image is mainly formed inside the grain.

The silver halide grains may have a regular crystal shape such as a cube, octahedron, or dodecahedron, or may have an irregular crystal shape such as a spherical shape or a plate shape. In these particles, any ratio of the (1io) plane to the (1ii) plane can be used. In addition, the particles may have a composite form of these crystal forms (particles of various crystal forms may be mixed).

Silver halide emulsions having any grain size distribution may be used.

The silver halide emulsion may be a mixture of two or more separately formed silver halide emulsions.

Silver halide emulsions can be chemically sensitized by conventional methods. That is, sulfur sensitization method, selenium sensitization method, reduction sensitization method,
A noble metal sensitization method using gold or other noble metal compounds can be used alone or in combination.

Silver halide emulsions can be optically sensitized to a desired wavelength range using dyes known in the photographic industry as sensitizing dyes. The sensitizing dyes may be used alone or in combination of two or more. Along with the sensitizing dye, the emulsion contains a dye that itself does not have a spectral sensitizing effect, or a supersensitizer, which is a compound that does not substantially absorb visible light and enhances the sensitizing effect of the sensitizing dye. Good too.

Sensitizing dyes include cyanine dyes, merocyanine dyes,
Complex cyanine dyes, complex merocyanine dyes, holopolar cyanine dyes, hemicyanine dyes, and hemioxynol dyes are used.

Particularly useful dyes include cyanine dyes, merocyanine dyes,
and a complex merocyanine pigment.

Silver halide emulsions are used during the manufacturing process of photosensitive materials, during storage,
Alternatively, for the purpose of preventing fog during photographic processing or to maintain stable photographic performance, photographs may be taken during chemical ripening, at the end of chemical ripening, and/or after chemical ripening and before coating a silver halide emulsion. Compounds known in the art as anti-capri agents or stabilizers can be added.゛It is advantageous to use gelatin as a binder (or protective colloid) for silver halide emulsions, but gelatin derivatives, graft polymers of gelatin and other polymers, other proteins, sugar derivatives, cellulose derivatives, monomers, etc. Hydrophilic colloids such as synthetic hydrophilic polymeric materials such as mono- or copolymers may also be used.

Photographic emulsion layers and other hydrophilic colloid layers of light-sensitive materials using silver halide emulsions are made by using one or more hardeners to crosslink binder (or protective colloid) molecules and increase film strength. Can be hardened. A hardening agent can be added to the processing solution to harden the photosensitive material to such an extent that it is not necessary to add a hardening agent, but it is also possible to add a hardening agent to the processing solution.

A plasticizer can be added to the silver halide emulsion layer and/or other hydrophilic colloid layer of the light-sensitive material for the purpose of increasing flexibility.

The photographic emulsion layer and other hydrophilic colloid layers of the light-sensitive material may contain a dispersion (latex) of a water-insoluble or sparingly soluble synthetic polymer for the purpose of improving dimensional stability.

The emulsion layer of the photosensitive material contains a dye-forming agent that forms a dye through a coupling reaction with an oxidized form of an aromatic primary amine developer (for example, p-phenylenediamine derivatives, aminophenol derivatives, etc.) during color development processing. A coupler is used. The dye-forming couplers are typically selected for each emulsion layer such that a dye is formed that absorbs light in the light-sensitive spectrum of the emulsion layer, with a yellow dye-forming coupler for the blue-sensitive emulsion layer and a dye for the green-sensitive emulsion layer. A magenta dye-forming coupler is used in the sensitive emulsion layer and a cyan dye-forming coupler is used in the red-sensitive emulsion layer. However, depending on the purpose, silver halide color photographic materials may be produced using different combinations from the above.

These dye-forming couplers preferably have a group called a ballast group in the molecule, which makes the coupler non-diffusive and has 8 or more carbon atoms. In addition, even if these dye-forming couplers are 4-isomatral, in which 4 silver ions need to be reduced in order to form one molecule of dye, only 2 silver ions need to be reduced. Either equimency is acceptable. Dye-forming couplers have the effect of color correction, and by coupling with oxidized forms of developing agents, bleaching accelerators, silver halide solvents, toning agents, hardeners, capping agents, and antifoggants can be produced. , chemical sensitizers, 16 spectral sensitizers, and desensitizers that release photographically useful fragments.

A colorless coupler (also called a competitive coupler) which undergoes a coupling reaction with an oxidized aromatic primary amine developer but does not form a dye can also be used in combination with a dye-forming coupler.

As the yellow dye-forming coupler, known acylacetanilide couplers can be preferably used. Among these, benzoylacetanilide and pivaloylacetanilide compounds are advantageous.

As the magenta dye-forming coupler, known 5-pyrazolone couplers, pyrazolopenzimidazole couplers, pyrazolotriazole couplers, open-chain acylacetonitrile couplers, indacylon couplers, and the like can be used.

Phenol or naphthol couplers are commonly used as cyan dye-forming couplers.

Among dye-forming couplers, colored couplers, image stabilizers, color antifoggants, ultraviolet absorbers, optical brighteners, etc. that do not need to be adsorbed on the silver halide crystal surface, hydrophobic compounds can be used using the solid dispersion method or latex dispersion method. Various methods can be used, such as , oil-in-water emulsion dispersion method, etc., and can be appropriately selected depending on the chemical structure of the hydrophobic compound such as the coupler. For the oil-in-water emulsion dispersion method, conventionally known methods for dispersing hydrophobic additives such as couplers can be applied.
Usually, it is dissolved in a high boiling point organic solvent with a boiling point of about 150°C or higher, if necessary, in combination with a low boiling point and/or water-soluble Cloth Ia solvent, and a surfactant is used in a hydrophilic binder such as an aqueous gelatin solution. After emulsifying and dispersing it using a dispersing means such as a stirrer, homogenizer, colloid mill, 70-jet mixer, or ultrasonic device, it may be added to the desired hydrophilic colloid liquid. A step of removing the low boiling point organic solvent may be included simultaneously with the dispersion or dispersion.

Examples of high-boiling point solvents include organic compounds with a boiling point of 150°C or higher, such as phenol derivatives, phthalate alkyl esters, phosphate esters, citric acid esters, benzoic acid esters, alkylamides, fatty acid esters, and trimesic acid esters, which do not react with the oxidized form of the developing agent. A solvent is used.

Low boiling or water-soluble organic solvents can be used in conjunction with or in place of high boiling solvents. Examples of organic solvents with low boiling points that are substantially insoluble in water include ethyl acetate, propyl acetate, butyl acetate, butanol, chloroform, carbon tetrachloride, nitromethane, nitroethane, and beshizene, and examples of water-soluble organic solvents include acetone, Methyl isobutyl ketone, β-ethoxyethyl acetate, methoxyglycol acetate, methanol, ethanol, acetonitrile, dioxane, dimethylformamide, dimethyl sulfoxide, hexamethylphosphoramide,

Anionic surfactants, nonionic surfactants, Cationic surfactants and amphoteric surfactants can be used.

The oxidized form of the developing agent or the electron transfer agent may migrate between the emulsion layers of the light-sensitive material (between the same color-sensitive layers and/or between different color-sensitive layers), causing color turbidity or deterioration of sharpness. -A color antifoggant can be used to prevent graininess from becoming noticeable.

The color antifoggant may be contained in the emulsion layer itself, or
An interlayer may be provided between adjacent emulsion layers and contained in the interlayer.

An image stabilizer can be used in the photosensitive material to prevent deterioration of the dye image.

Hydrophilic colloid layers such as protective layers and intermediate layers of photosensitive materials contain ultraviolet absorbers to prevent fogging caused by discharge caused by charging of photosensitive materials due to friction, etc., and to prevent deterioration of images due to ultraviolet rays. Good too.

In order to prevent deterioration of magenta dye-forming couplers and the like due to formalin during storage of the light-sensitive material, a formalin scavenger can be used in the light-sensitive material.

When containing dyes, ultraviolet absorbers, etc. in the hydrophilic colloid layer of a photosensitive material, they may be mordanted with a mordant such as a cationic polymer.

Compounds that change the developability, such as development accelerators and development retarders, can be added to the silver halide emulsion layer and/or other hydrophilic colloid layers of the light-sensitive material.

The emulsion layer of a photographic light-sensitive material is made of polyalkylene oxide or its derivatives such as ethers, esters, and amines, thioether compounds, thiomorpholines, quaternary ammonium compounds, urethane derivatives, etc. for the purpose of increasing sensitivity, increasing contrast, or promoting development. It may also contain urea derivatives, imidazole derivatives, and the like.

A fluorescent whitening agent can be used in the photosensitive material for the purpose of emphasizing the whiteness of the white background and making the coloration of the white background less noticeable.

The photosensitive material can be provided with auxiliary layers such as a filter layer, an antihalation layer, and an antiirradiation layer. These layers and/or the emulsion layer may contain dyes that are washed out or bleached from the light-sensitive material during the development process. Such dyes include oxonol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, cyanine dyes, azo dyes, and the like.

A matting agent can be added for the purpose of preventing photosensitive materials from sticking to each other.

A lubricant can be added to the photosensitive material to reduce sliding friction.

An antistatic agent can be added to the photosensitive material for the purpose of preventing static electricity. The antistatic agent may be used in the antistatic layer on the side of the support on which the emulsion is not laminated, and the protective colloid layer other than the emulsion layer on the side on which the emulsion layer is laminated with respect to the emulsion layer and/or the support. May be used for.

The photographic emulsion layer and/or other hydrophilic colloid layer of the light-sensitive material may be coated with coating properties, antistatic properties, slipperiness properties, emulsification dispersion,
Various surfactants can be used for the purpose of preventing adhesion and improving photographic properties (development acceleration, film hardening, sensitization, etc.).

Flexible reflective supports such as synthetic paper, films made of semi-synthetic or synthetic polymers such as cellulose acetate, cellulose nitrate, polystyrene, polyvinyl chloride, polyethylene terephthalate, polycarbonate, and polyamide, and reflective layers on these films. Includes flexible supports provided, such as glass, metal, ceramics, etc.

After subjecting the surface of the support to corona discharge, ultraviolet irradiation, flame treatment, etc. as necessary, the photosensitive material can be used directly or to improve the adhesion, antistatic properties, dimensional stability, abrasion resistance, hardness, etc. of the support surface.
It may be applied through one or more subbing layers to improve antihalation properties, frictional properties, and/or other properties.

When coating the photosensitive material, a thickener may be used to improve coating properties. Also, for example! ! Like IFJ drugs,
For substances that have a fast reactivity and may cause gelation before coating if added to the coating solution in advance, it is preferable to mix them using a static mixer or the like immediately before coating.

As coating methods, extrusion coating and curtain coating, which allow two or more types of layers to be applied simultaneously, are particularly useful, but packet coating may also be used depending on the purpose. Further, the coating speed can be arbitrarily selected.

The processing method of the present invention usually includes a color development process, a bleaching process, a fixing process, a washing process, and, if necessary, a stabilizing process. Instead of the processing step, a bleach-fixing step can also be carried out using a one-bath bleach-fixing solution.

In combination with these processing steps, a pre-hardening process, its neutralization process, a stop-fixing process, a post-hardening process, etc. may be performed. In these treatments, instead of the color development treatment step, an activator treatment step may be performed in which a color developing agent or its precursor is contained in the U-containing agent and the development treatment is carried out using an activator solution. Among these processes, typical processes are shown below.
