Description

The present invention relates to a silver halide color photographic material.
The fundamental steps of processing silver halide color photographic materials generally include a color development step and a desilvering step. In the color development step, exposed silver halide is reduced with a color developing agent to form silver and the oxidized color developing agent reacts with a color former (coupler) to yield a dye image. In the subsequent desilvering step, the silver thus formed is oxidized with a bleaching agent, further changed into a soluble silver complex by a fixing agent and then dissolved away.
In recent years, it has been strongly desired to accelerate the processing, that is, to shorten the processing time in this field. In the above-described color development processing, there is a strong need to shorten the time for the desilvering step which occupies nearly one half of the total processing time.
In response to such a need for shortening the time for the desilvering step, there are known bleach-fixing solutions which contain an aminopolycarboxylic acid ferric ion complex salt and a thiosulfate in a single solution, as described in DE-B- 866,605. However, the bleaching ability of the solution is very weak since an aminopolycarboxylic acid ferric ion complex salt which per se is weak in oxidizing power (bleaching ability) and a thiosulfate which has a reducing power are coexistent in a single solution. Therefore, it is very difficult for the bleach-fixing solution to sufficiently achieve desilveration of color photographic materials, particularly for elements of high sensitivity and high silver content; consequently it cannot be employed for practical use.
On the other hand, for the purpose of increasing the bleaching ability, there has been proposed a method where various kinds of bleach accelerating agents are added to a bleaching bath, bleach-fixing bath or a prebath thereof. Examples of these bleach accelerating agents include various mercapto compounds as described in US-A-3,893,858, GB-B-1,138,842, and JP-A-53-141623 (the term "JP-A" as used herein means an "unexamined published Japanese patent application"); compounds having a disulfide bond as described in JP-A-53-95630; thiazolidine derivatives as described in JP-B-53-9854 (the term "JP-B" as used herein means an "examined Japanese patent publication"); isothiourea derivatives as described in JP-A-53-94927; thiourea derivatives as described in JP-B-45-8506 and JP-B-49-26586; thioamide compounds as described in JP-A-49-42349; dithiocarbarmates as described in JP-A-55-26506; and arylenediamine compounds as described in US-A-4,552,834.
Although some of these bleach accelerating agents exhibit certain bleach accelerating effects, they are expensive compounds orthey are insufficiently stable in the bath having bleaching ability. Further, their bleach accelerating effect per se is still insufficient and thus they are not satisfactorily employed for practical use.
Moreover, in the case of conducting processing with a bleaching bath, bleach-fixing bath or prebath thereof containing various bleach accelerating agents described above, where the bleach accelerating agent is a compound having a mercapto group, the mercapto compound may react with undeveloped silver halide or silver halide formed by a bleaching reaction present in an emulsion layer of a photographic material to form a sparingly soluble silver salt which is not solubilized by a fixing agent and, as a result, cause insufficient fixing.
Further, when a continuous processing method with replenishment is performed using a processing bath having bleach-fixing ability, silver ions are accumulated in the bleach-fixing bath. Silver ions form a sparingly soluble silver salt with a mercapto compound. This reaction is particularly apt to occur in the case where iodide ions are present in the bleach-fixing bath employed.
As described above, there are many restrictions for the use of bleach accelerating agents in a bleaching bath, bleach-fixing bath or a prebath thereof.
It is also known that a photographic light-sensitive material containing the above-described mercapto compound or a precursor thereof which is a bleach accelerating agent can be processed. However, this method also has many problems in that the mercapto compound adversely affects photographic properties of the photographic light-sensitive material to which it is added and in that the mercapto compound reacts with silver halide at an undeveloped portion of the photographic material to form a sparingly soluble silver salt.
There is also a disclosure with respect to couplers capable of releasing a bleach accelerating compound in Research Disclosure, No. 24241, ibid., No. 11449, and JP-A-61-201247.
It is also known that sensitivity is increased and graininess is improved by a silver halide color photographic material having a high iodide content, i.e., using a silver halide emulsion which contains a large amount of silver iodide.
However, an increase in the silver iodide content in a silver halide color photographic material causes a new problem on deterioration of desilvering. In addition, such deterioration of desilvering cannot be prevented by the addition of a bleach accelerating agent to a bleaching bath, bleach-fixing bath or prebath thereof in a conventional manner as described above. Aphotographic light-sensitive material containing a high silver iodide content emulsion is inferior in its desilvering property as compared to one with a low silver iodide content emulsion.
DE-A-3641861 relates to the desilverization of photographic materials containing silver iodobromide emulsions of high iodide content employed to obtain an improved graininess, said photographic materials comprising a support having thereon silver halide emulsion layers containing iodobromide grains of an average iodide content of 7 mol% or more and containing a naphthol type coupler and a DIR coupler.
From EP-A-0277647 and EP-A-0307927, both belonging to the state of the art according to Article 54(3) EPC, it is known to incorporate into a silver halide color photographic material naphthol type couplers having diffusible substituents released upon coupling with an oxidized primary aromatic amine color developing agent and to employ silver halide emulsions having an average iodide content of 7 mol% or more.
It is the object of the present invention to provide a silver halide color photographic material which has an excellent desilvering property and good graininess.
According to the present invention this object is attained with a silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material contains at least one silver halide emulsion containing silver iodide grains whose average iodide content is at least 7 mol % and at least one compound capable of releasing a bleach accelerating agent upon reaction with an oxidation product of an aromatic primary amine type color developing agent, said compound having the following general formula (I):
wherein A represents a group whose bond to (L1)_a-(L₂)_b-Z is capable of being cleaved upon reaction with an oxidation product of a developing agent; L₁ represents a timing group or a group whose bond to (L₂)_b-Z is capable of being cleaved upon reaction with an oxidation product of a developing agent; L₂ represents a timing group or a group whose bond to Z is capable of being released upon reaction with an oxidation product of a developing agent; a and b each represents 0 or 1 and Z is a group represented by formula (XII), (XIII) or (XIV);

wherein the bond indicated by * denotes the position at which the group is connected to A-(L₁)_a-(L₂)b-; R₃₁ represents a divalent aliphatic group having from 1 to 8 carbon atoms; R₃₂ represents a group as defined for R_31' a divalent aromatic group having from 6 to 10 carbon atoms or a 3-membered to 8-membered divalent heterocyclic group; X₁ represents -O-, -S-, -COO-, -SO₂-,

X₂ represents an aromatic group having from 6 to 10 carbon atoms; X₃ represents a 3-membered to 8-membered, preferably 5-membered or 6-membered heterocyclic group containing at least one carbon atom which is connected to S in the ring; Y₁ represents a carboxy group, a salt thereof, a sulfo group or a salt thereof, a hydroxy group, a phosphonic acid group or a salt thereof, an amino group which is substituted with an aliphatic group having from 1 to 4 carbon atoms, -NHS0₂R₃₅ or-SO₂NHR₃₅; Y₂ represents a group as defined for Y₁ or a hydrogen atom; r represents 0 or 1; f represents an integer from 0 to 4; m represents an integer from 1 to 4; u represents an integer from more than 0 up to 4; provided that myl's may be connected at a position which can be substituted on R₃₁-{(X₁)_r-R₃₂}l, X₂-{(X₁)_r-R₃₂]l or X₃-{(X₁)_rR₃₂}l;
when m represents 2 or more, two or more Y₁' may be the same or different; when f represents 2 or more, two or more (X1)_r-R₃₂'s may be the same or different; R₃₃, R34 and R₃₅ each represents a hydrogen atom or an aliphatic group having from 1 to 8 carbon atoms,
with the proviso that said compound is not
In accordance with the present invention, a deterioration in desilvering capability which occurs in photographic light-sensitive materials comprising a high silver iodide content emulsion and which could not be sufficiently prevented by using conventional bleach accelerating agents is effectively eliminated by means of the incorporation of the compound capable of releasing a bleach accelerating agent having the general formula (I).
The silver halide emulsion whose average iodide content is at least 7 mol% according to the present invention is now described in detail (hereinafter referred to as "silver halide emulsion having a high silver iodide content"). iodide content silver halide emulsion which is effectively employed in the present invention is determined by the solid solution limiting value to be 40 mol %. Therefore, in the present invention, a silver halide emulsion whose silver iodide content is preferably in a range from 8 mol % to 40 mol %, more preferably in a range from 10 mol % to 30 mol %, and further more preferably in a range from 12 mol % to 25 mol %, is employed together with the compound capable of releasing a bleach accelerating agent according to the present invention. When the silver iodide content is lower than the lower limit described above, the effect of the present invention generally decreases to some extent.
While the grain size of the high iodide content silver halide emulsion according to the present invention may be appropriately selected, when the high iodide content silver halide emulsion which preferably has a grain size of not less than 0.8 f..lm, more preferably not less than 1.5 µm, is employed together with the compound capable of releasing a bleach accelerating agent according to the present invention, a color photographic light-sensitive material having high sensitivity and improved desilvering property is obtained.
The high iodide content emulsion which is used in the present invention can be prepared using various methods. Specifically, any of, e.g., an acid process, a neutral process and an ammonia process, can be employed. Further, soluble silver salts and soluble halogen salts can be reacted by techniques such as a single jet process, a double jet process, and a combination thereof.
As one system of the double jet process, a controlled double jet process in which the pAg in the liquid phase where silver halide is formed is maintained at a predetermined level can be employed. As another system of the double jet process, a triple jet process in which soluble halogen salts having different compositions from each other are added individually (for example, a soluble silver salt, a soluble bromide and a soluble iodide) can also be employed.
In orderto prepare an emulsion of relatively large size grains, it is preferred to employ a silver halide solvent, for example, ammonia, thiocyanates, thioureas or amines as described in T.H. James ed., The Theory of the Photographic Process, Fourth Edition, page 9, Macmillan Publishing Co., Inc. (1977).
It is well known in the art that pH and pAg are controlled during the formation of silver halide grains so as to obtain preferred photographic properties. The pH may be preferably varied in a range from 2 to 10, depending on the method for preparation of grains.
Silver halide grains in the high iodide content emulsion according to the present invention may have a regular crystal structure, for example, a hexahedral, octahedral, dodecahedral or tetradecahedral structure, or an irregular crystal structure, for example, a spherical or tabular structure.
The inner portion and the surface layer of the silver halide grains may be different in halogen composition or may be uniform. Double structure grains in which the inner portion (core) is composed of silver iodochlorobromide or silver iodobromide containing a high concentration of silver iodide and the outer portion (shell) is composed of silver chloroiodobromide or silver iodobromide of a low silver iodide content are preferably employed in the emulsion according to the present invention. The ratio of the silver amount in the core and the shell can be selected in a wide range, but is preferably in the range from 5/1 to 1/5 (core Ag amount/shell Ag amount).
With respect to double structure grains, the object of the present invention can be achieved by a silver halide emulsion in which the average value of the silver iodide content in the grains is not less than 7 mol %. More specifically, the silver iodide content in the core is preferably selected to be not less than 15 mol %, more preferably not less than 25 mol %, further more preferably from 35 mol % to the solid solution limiting value of silver iodobromide (refer to T.H. James ed., The Theory of the Photographic Process, Fourth Edition, page 4). On the other hand, the silver iodide content in the shell is preferably not more than 5 mol % and more preferably not more than 2 mol %.
The formation or physical ripening of the silver halide grains may be carried out in the presence of, e.g., cadmium salts, zinc salts, lead salts, thallium salts, iridium salts or complex salts thereof, rhodium salts or complex salts thereof and iron salts or complex salts thereof.
For removal of soluble salts from the emulsion after precipitate formation or physical ripening, the well known noodle washing process in which gelatin is gelated may be used. In addition, a flocculation process utilizing inorganic salts having a polyvalent anion (for example, sodium sulfate), anionic surface active agents, anionic polymers (for example, polystyrene sulfonic acid), or gelatin derivatives (for example, aliphatic acylated gelatin, aromatic acylated gelatin and aromatic carbamoylated gelatin, aromatic acylated gelatin and aromatic carbamoylated gelatin) may be used.
Silver halide emulsions are usually chemically sensitized. For this chemical sensitization, for example, the methods as described in H. Frieser ed., Die Grundlagen der Photographischen Prozesse mit Silberhalogeni- den, Akademische Verlagsgesellschaft, pages 675 to 734 (1968) can be used. More specifically, a sulfur sensitization using active gelatin or compounds (for example, thiosulfates, thioureas, mercapto compounds and rhodanines) containing sulfur capable of reacting with silver; a reduction sensitization using reducing substances (for example, stannous salts, amines, hydrazine derivatives, formamidinesulfinic acid, and silane compounds); a noble metal sensitization using noble metal compounds (for example, complex salts of Group VIII metals in the Periodic Table, such as, e.g., Pt, Ir and Pd, as well as gold complex salts); can be applied alone or in combination with each other.
The photographic emulsion used in the present invention may include various compounds for the purpose of preventing fog formation or stabilizing photographic performance in the photographic light-sensitive material during the production, storage or photographic processing thereof. For example, compounds known as antifoggants or stabilizers can be incorporated, including for example azoles such as, e.g., benzothiazolium salts, nitroimidazoles, nitrobenzimidazoles, chlorobenzimidazoles, bromobenzimidazoles, mercaptothiazoles, mercaptobenzothiazoles, mercaptobenzimidazoles, mercaptothiadiazoles, aminotriazoles, benzotriazoles, nitro- benzotriazoles and mercaptotetrazoles (particularly 1-phenyl-5-mercaptotetrazole); mercaptopyrimidines; mercaptotriazines; thioketo compounds such as, e.g., oxazolinethione; azaindenes such as, e.g., triazain- denes, tetraazaindenes (particularly 4-hydroxy-substituted (1,3,3a,7)tetraazaindenes) and pentaazaindenes; benzenethiosulfonic acids; benzenesulfinic acids and benzenesulfonic amides.
The photographic emulsion used in the present invention may also be spectrally sensitized with methine dyes or other dyes. Suitable dyes which can be employed include cyanine dyes, merocyanine dyes, complex cyanine dyes, complex merocyanine dyes, holopolar cyanine dyes, hemicyanine dyes, styryl dyes, and hem- ioxonol dyes. Of these dyes, cyanine dyes, merocyanine dyes and complex merocyanine dyes are particularly useful. Any conventionally utilized nucleus for cyanine dyes, such as basic heterocyclic nuclei, is applicable to these dyes. That is, e.g., a pyrroline nucleus, an oxazoline nucleus, a thiazoline nucleus, a pyrrole nucleus, an oxazole nucleus, a thiazole nucleus, a selenazole nucleus, an imidazole nucleus, a tetrazole nucleus and a pyridin nucleus, and further, nuclei formed by condensing alicyclic hydrocarbon rings with these nuclei and nuclei formed by condensing aromatic hydrocarbon rings with these nuclei, that is, e.g., an indolenine nucleus, a benzindolenine nucleus, an indole nucleus, a benzoxazole nucleus, a naphthoxazole nucleus, a benzothiazole nucleus, a naphthothiazole nucleus, a benzoselenazole nucleus, a benzimidazole nucleus and a quinoline nucleus, are appropriate. The carbon atoms of these nuclei can also be substituted.
In addition, to merocyanine dyes and complex merocyanine dyes, as nuclei having a keto-methylene structure, 5-membered or 6-membered heterocyclic nuclei such as a pyrazolin-5-one nucleus, a thiohydantoin nucleus, a 2-thioxazolidin-2,4-dione nucleus, a thiazolidin-2,4-dione nucleus, a rhodanine nucleus, and a thiobarbituric acid nucleus may also be used.
Useful sensitizing dyes include those as described, for example, in DE-B-929,080, US-A-2,231,658, US-A-2,493,748, US-A-2,503,776, US-A-2,519,001, US-A-2,912,329, US-A-3,656,959, US-A-3,672,897, US-A-3,694,217, US-A-4,025,349 and US-A-4,046,572, GB-B-1,242,588, JP-B-44-14030 and JP-B-52-24844.
These sensitizing dyes can be employed individually, and can also be employed in combination. A combination of sensitizing dyes is often used, particularly for the purpose of supersensitization.
Representative examples thereof are described, for example, in US-A-2,688,544, US-A-2,977,229, US-A-3,397,060, US-A-3,522,052, US-A-3,527,641, US-A-3,617,293, US-A-3,628,964, US-A-3,666,480, US-A-3,672,898, US-A-3,679,428, US-A-3,703,377, US-A-3,769,301, US-A-3,814,609, US-A-3,837,862 and US-A-4,026,707, GB-B-1,344,281 and GB-B-1,507,803, JP-B-43-4936, JP-B-53-12375, JP-A-52-110618 and JP-A-52-109925.
The sensitizing dyes may be present in the emulsion together with dyes which themselves do not give rise to any spectral sensitizing effects but exhibit a supersensitizing effect or materials which do not substantially absorb visible light but exhibit a supersensitizing effect. For example, aminostilbene compounds substituted with a nitrogen-containing heterocyclic group (for example, those described in US-A-2,933,390 and US-A-3,635,721), aromatic organic acid-formaldehyde condensates (for example, those described in US-A-3,743,510), cadmium salts, and azaindene compounds can be present. The combinations as described in US-A-3,615,613, US-A-3,615,641, US-A-3,617,295 and US-A-3,635,721 are particularly useful.
The present invention is also applicable to multilayer multicolor photographic materials having layers sensitive to at least two different spectral wavelength ranges on a support. Amultilayer natural color photographic material generally possesses at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer, and at least one blue-sensitive silver halide emulsion layer, respectively, on a support. The order of these layers can be varied, if desired. Ordinarily, a cyan-forming coupler is present in a red-sensitive emulsion layer, a magenta-forming coupler is present in a green-sensitive emulsion layer, and a yellow-forming coupler is present in a blue-sensitive emulsion layer, respectively. However, if desired, different combinations can be employed.
The compound capable of releasing a bleach accelerating agent which can be used in the present invention is now described in detail.
In the general formula (I), A specifically represents a coupler residual group or an oxidation reduction group.
When A represents a coupler residual group, any known coupler residual group can be utilized. Suitable examples thereof include a yellow coupler residual group (for example, an open-chain ketomethylene type coupler residual group), a magenta coupler residual group (for example, a 5-pyrazolone type coupler residual group, a pyrazoloimidazole type coupler residual group or a pyrazolotriazole type coupler residual group), a cyan coupler residual group (for example, a phenol type coupler residual group or a naphthol type coupler residual group), and a non-color forming coupler residual group (for example, an indanone type coupler residual group or an acetophenone type coupler residual group). Further, the heterocyclic type coupler residual groups as described in for example, US-A-4,315,070, US-A-4,183,752, US-A-3,961,959and US-A-4,171,223 are also useful.

These coupler residual groups are preferred because of their high coupling rates.
In the above-described general formulae, the free bond attached to the coupling position indicates a position to which a group capable of being released upon coupling is bonded.

In other cases, the total number of carbon atoms included therein is preferably not more than 15. In cases of bis, telomer or polymer couplers, any of the above-described substituents forms a divalent group and may connect to a repeating unit, for instance. In such cases, the total number of carbon atoms can be outside of the above-described range.

The photographic emulsions used in the present invention are usually subject to, after physical ripening, chemical ripening and spectral sensitization. Various kinds of additives which can be employed in these steps are described, for example, in Research Disclosure, No. 18743 (December 1978) and ibid., No. 18716 (November 1979) as mentioned above and relevant parts thereof are summarized in the table shown below.
Further, known photographic additives which can be used in the present invention are also described in the above mentioned Research Disclosure, No. 17643 (Dec. 1978) and ibid., No. 18716 (Nov. 1979) and relevant parts thereof are summarized in the table shown below.
In the color photographic light-sensitive material of the present invention, various known spectral sensitizers can be employed together, as well as the above described spectral sensitizers.
In the present invention, various color couplers can be employed and specific examples thereof are described, for example, in the patents cited in Research Disclosure, No. 18743, "VII-C" to "VII-G" as mentioned above. As dye forming couplers, couplers capable of providing the three primary colors (i.e., yellow, magenta and cyan) in a subtractive process upon color development are important. Specific examples of preferred diffusion-resistant, four-equivalent or two-equivalent couplers are described in the patents cited in Research Disclosure, No. 17643, "VII-C" and "VII-D" as mentioned above. In addition, couplers as described below are preferably employed in the present invention.
As typical yellow couplers used in the present invention, known yellow couplers of the oxygen atom releasing type and known yellow couplers of the nitrogen atom releasing type can be exemplified. a-Pivaloyla- cetanilide type couplers are characterized by excellent fastness, particularly light fastness, of the dyes formed, and the a-benzoylacetanilide type couplers are characterized by providing high color density.
As magenta couplers used in the present invention, hydrophobic 5-pyrazolone type couplers and pyrazoloazole type couplers each having a ballast group may be employed. Of the 5-pyrazolone type couplers, those substituted with an arylamino group or an acylamino group at the 3-position thereof are preferred in view of hue and color density of dyes formed therefrom.
As cyan couplers used in the present invention, hydrophobic and diffusion-resistant naphthol type and phenol type couplers can be exemplified. Typical examples preferably include oxygen atom releasing type two-equivalent naphthol type couplers.
Cyan couplers capable of forming cyan dyes fast to humidity and temperature are preferably used in the present invention.

Further, couplers capable of forming appropriately diffusible dyes can be used together in order to improve graininess. Specific examples of such types of magenta couplers are described, for example, in US-A-4,336,237, and those of yellow, magenta and cyan couplers are described, for example, in EP-B-96,570.
Dye forming couplers and special couplers as described above may form polymers including dimers or more. Typical examples of polymer dye forming couplers are described, for example, in US-A-3,451,820. Specific examples of polymer magenta couplers are described, for example, in US-A-4,367,282.
Couplers capable of releasing a photographically useful group during the course of coupling can also be employed preferably in the present invention. Specific examples of useful DIR couplers capable of releasing a development inhibitor are described, for example, in the patents cited in Research Disclosure, NO. 17643, "VII-F" described above.
A DIR coupler is a compound which can release a development inhibitor releasing compound upon reaction with the oxidation product of the developing agent during development. Generally, the development inhibitor is adsorbed on the silver, which causes to retard the desilvering.
As the intensive study of the present inventors, it was found that when to a multilayer color photogrpahic material which uses the high iodide content emulsion was added the DIR coupler in an amount of 1 mol% or more, 2 mol% or more, on particularly 3 mol% or more per all silver amount coated, desilverization was remarkably deteriorated though sharpness and color reproducibility are generally improved. In order to resolve the problem, it was found that the co-use of the compound capable of releasing a bleach accelerating agent according to the present invention is particularly preferred. It is not anticipated by the conventional techniques.

The pH of the color developing solution used is usually 7 or more and preferably in a range from about 9 to about 13.
In accordance with the present invention, the silver halide color photographic material is imagewise exposed, subjected to color development processing as described above, and then processed with a processing solution having bleaching ability.
A processing solution having bleaching ability for use in the present invention practically means a processing solution which has the ability to oxidize metal silver formed upon development and colloidal silver contained in the photographic material and convert them to soluble silver salt such as silver thiocyanate complex salt or an insoluble silver salt such as a silver bromide, and includes, for example, a bleaching solution and a bleach-fixing solution. It is preferred in the present invention, that the color photographic material is processed with a processing solution having bleach-fixing ability just after color development.
The bleaching agents which can be used in the processing solution having bleaching ability include oxidizing agents, for example, ferric complexes such as ferricyan iron complex and ferric citrate complex, persulfates and peroxides such as hydrogen peroxide, but preferably aminopolycarboxylic acid ferric complex salts, i.e., the complex salts of ferric ions and aminopolycarboxylic acids or the salts thereof.

The aminopolycarboxylic acid ferric complex salt may be used in the form of a complex salt or may be formed in a solution using a ferric salt such as, e.g., ferric sulfate, ferric chloride, ferric nitrate, ammonium ferric sulfate and ferric phosphate, and an amino-polycarboxylic acid. In the case of using a complex salt, the complex salt may be used solely or as a mixture of two or more complex salts. On the other hand, when the complex salt is formed in a solution using a ferric salt and an aminopolycarboxylic acid, one or more types of ferric salts may be used and also one or more kinds of aminopolycarboxylic acids may be used. Also, in any case, aminopolycarboxylic acid(s) may be used in excess of the amount required for forming the ferric complex salt.
A combination of at least one of the above described ferric (Fe(III)) complex salts of the aminopolycarboxylic acids excluding Compound (19) and the ethylenediamine-tetraacetic acid ferric complex salt may be used.
Furthermore, a processing solution having a bleaching ability containing the above described ferric complex salt may further contain a complex salt of a metal ion other than an iron ion, such as, e.g., a cobalt ion, a nickel ion or a copper ion.
The amount of the bleaching agent is generally from 0.1 mol to 1 mol, preferably from 0.2 mol to 0.5 mol per I of the processing solution having bleaching ability. Also, the pH of the bleaching solution is preferably from 4.0 to 8.0, and particularly preferably from 5.0 to 7.5.
The processing solution having bleaching ability used in the present invention usually further contains a rehalogenating agent such as a bromide (for example, potassium bromide, sodium bromide, or ammonium bromide) and a chloride (for example, potassium chloride, sodium chloride, or ammonium chloride) in addition to the bleaching agent and the above described compound. Moreover, the processing solution may contain known additives for conventional bleach fixing solutions, for example, at least one inorganic acid, organic acids or salts thereof having a pH buffering function, such as nitrates (for example, sodium nitrate, or ammonium nitrate), boric acid, borax, sodium metaborate, acetic acid, sodium acetate, sodium carbonte, potassium carbonate, phosphorus acid, phosphoric acid, sodium phosphate, citric acid, sodium nitrate, or tartaric acid.
In the present invention, a fixing bath following the bleaching bath ora processing solution having a bleach-fixing ability may contain a known fixing agent(s) such as, e.g., a thiosulfate (for example, sodium thiosulfate, ammonium thiosulfate, ammonium sodium thiosulfate, or potassium thiosulfate), a thiocyanate (for example, ammonium thiocyanate, or potassium thiocyanate), thiourea and thioether. The addition amount of the fixing agent is preferably about 3 mol or less, particularly preferably 2 mol or less per I of the processing solution having a fixing ability or a bleach-fixing ability.
The processing solution having bleach-fixing ability used in the present invention may further contain a sulfite ion releasing compound such as a sulfite (for example, sodium sulfite, or ammonium sulfite), a bisulfite, or a bisulfite addition product of an aldehyde (for example, carbonyl bisulfite).
Further, the processing solution having bleach-fixing ability may contain the aminopolycarboxylic acid or the salt thereof as shown above as Compounds (1) to (19), or an organic phosphonic acid compound such as, e.g., ethylenediaminetetrakismethylenephosphonic acid, diethylenetriaminepentakismethylenephosphonic acid, 1,3-diaminopropanetetrakismethylenephosphonic acid, nitro- N,N,N-trimethylenephosphonic acid or 1-hydroxyethyiidene-1,1'-diphosphonic acid.
According to the present invention, the processing solution having bleaching ability can further contain at least one bleach accelerating agent selected from compounds having a mercapto group or a disulfide bond, isothiourea derivatives, and thiazolidine derivatives. The amount of the bleach accelerating agent is preferably from 1x10-⁵ to 1 x1 0-1 mol, particularly preferably from 1 x1 0-4 to 5x10-² mol, per I of the processing solution having bleach-fixing ability.
As described, the bleach accelerating agent which can be contained in the processing solution having bleaching ability is selected from compounds having a mercapto group or a disulfide bond, thiazolidine derivatives, thiourea derivatives, and isothiourea derivatives each having a bleach accelerating effect. Peferred compounds are those represented by the general formulae (a) to (g) and specific examples thereof as described in JP-A-63-163853 pages 63 to 77.
The bleach accelerating agent described above is generally added to the processing solution having bleaching ability, e.g., as a solution thereof in water, an alkaline aqueous solution, an organic acid or an organic solvent, but the agent may be added as a powder thereof without having any adverse influence on the bleach accelerating effect.
Furthermore, the bleach accelerating agent can be incorporated into the color photographic light-sensitive material in the present invention. In such case, the bleach accelerating agent may be incorporated into any one of the blue-sensitive emulsion layer, the green-sensitive emulsion layer or the red-sensitive emulsion layer of the color photographic material or in another gelatin layer such as the uppermost layer, an intermediate layer or the lowermost layer of the color photographic material.
The processing bath having bleach-fixing ability may be a processing step composed of one processing tank or composed of two or more processing tanks. In the latter case, a multistage countercurrent system may be employed with the supply of a replenisher for the processing solution or the processing solution may be successively circulated through plural tanks and the replenisher may be supplied to one of the plural tanks.
After a desilvering step such as a fixing step or a bleach-fixing step, the silver halide color photographic material according to the present invention is generally subjected to a water washing step and/or a stabilizing step.
An amount of water required for the water washing step may be set in a wide range depending on, for example, characteristics of photographic light-sensitive materials (due to elements used therein, for example, couplers) uses thereof, temperature of washing water, a number of water washing tanks (stages), a replenishment system such as counter current or orderly current, or other various conditions. The relationship between a number of water washing tanks and the amount of water in a multi-stage countercurrent system can be determined based on the method as described in Journal of the Society of Motion Picture and Television Engineers, Vol. 64, pages 248 to 253 (May, 1955).
According to the multi-stage countercurrent system described in the above literature, the amount of water for washing can be significantly reduced. However, an increase in the residence time of the water in a tank causes propagation of bacteria and some problems such as, e.g., adhesion of scum formed on the photographic materials, occur. In the method of processing the silver halide color photographic material according to the present invention, a method for reducing the amounts of calcium ions and magnesium ions as described in JP-A-62-288838 can be particularly effectively employed in order to solve such problems. Further, sterilizers, for example, isothiazolone compounds as described in JP-A-57-8542, cyabendazoles, chlorine type sterilizers such as, e.g., sodium chloroisocyanurate, benzotriazoles, sterilizers as described in Hiroshi Horiguchi, Bokin Bobai No Kagaku ("Chemistry of Bactericides and Fungicides"), Biseibutsu No Mekkin-, Sakkin-, Bobai-Gijutsu ("Techniques of Sterilization, Pasteurization and Fungicides of Microorganisms"), edited by Eiseigijutsu Kai ("Sanitary technology Society"), and Bokin-Bobaizai Jiten ("Dictionary of Bactericides and Fungicides"), edited by Nippon Bokin-Bobai Gakkai ("Japan Bactericide and Fungicide Society"), can be employed.
The pH of the washing water used in the processing of the photographic light-sensitive materials according to the present invention is usually from 4 to 9, preferably from 5 to 8. The temperature of the washing water and the time for any water washing step can be variously set depending on, e.g., characteristics or uses of the photographic light-sensitive materials. However, it is generally the case that one selects a range of from 15°C to 45°C and a period from 20 s to 10 min and preferably a range of from 25°C to 40°C and a period from 30 s to 5 min.
The photographic light-sensitive material of the present invention can also be directly processed with a stabilizing solution in place of the above-described water washing step. In such a stabilizing process, any known methods as described in JP-A-57-8543, JP-A-58-14834, JP-A-59-184343, JP-A-60-220345, JP-A-60-238832, JP-A-60-239784, JP-A-60-239749, JP-A-61-4054 and JP-A-61-118749 can be employed. A stabilizing bath containing 1-hydroxyethyiidene-1,1-diphosphonicacid, 5-chloro-2-methyl-4-isothiazolin-3-one, a bismuth compound and an ammonium compound is particularly preferably employed.
Further, it is possible to conduct stabilizing process subsequent to the above-described water washing process. One example thereof is a stabilizing process subsequent to the above-described water washing process. One example thereof is a stabilizing bath containing formalin and a surface active agent, which is employed as a final bath in the processing of color photographic light-sensitive materials for photographing.
The present invention is explained in greater detail with reference to the following examples.
Unless specified otherwise, all percents and ratios are by weight.

After physical ripening for 20 min, 1000 ml of an aqueous solution containing 0.67 mol of silver nitrate and 1000 ml of an aqueous solution containing 0.67 mol of potassium bromide were added simultaneously over a period of 50 min thereto while maintaining the pAg at 8.6. After desalting, 2x10-⁵ mol of sodium thiosulfate and 4x10-⁵ mol of chloroauric acid were added to the emulsion and the emulsion was chemically sensitized at 60°C for 60 min, whereby a silver iodobromide emulsion having an average grain size of 1.1 f..lm and containing 6 mol % of silver iodide was obtained. This emulsion was designated Emulsion A.
Using a 2% aqueous solution of gelatin containing 0.37 mol of potassium bromide and 0.10 mol of potassium iodide, the basic procedure for the preparation of Emulsion A above was repeated to obtain a silver iodobromide emulsion B having an average grain size of 1.0 µm and containing 10 mol % of silver iodide.

Samples 202 to 215

Samples 202 to 215 were prepared in the same manner as described for Sample 201 except that the silver halide emulsion used in the fourth layer was replaced with each of Emulsions B to E as described in Example 1, Coupler ExC-7 used in the fourth layer was substituted with the coupler according to the present invention, and Coupler ExC-2 used in the third layer was also substituted with the coupler according to the present invention as described in Table 2 below, respectively.
Samples 201 and 215 thus prepared were exposed to white light of 20 CMS and then subjected to development processing according to Processing Steps (I) to (III) with the processing solutions as described in Example 1 (after the running test), except that the bleaching time of Processing Step (I) was changed to 3 min, the bleach-fixing time of Processing Steps (II) was changed to 1 min, and the bleach-fixing time of Processing Step (III) was changed to 3 min, respectively. The amount of remaining silver and the RMS value were determined in the same manner as described in Example 1.
The results obtained are shown in Table 2 below. From the results shown in Table 2, it is apparent that the combination of the silver halide emulsion and the coupler according to the present invention provides remarkably improved graininess and desilvering property.

EXAMPLE 3

Samples 301, 302 and 303 were prepared in the same manner as described for Sample 202 of Example 2 except ExM-8 used in the seventh layer was substituted with an-equimolar amount (calculated as a color forming unit in case of a polymer coupler) of Compound (5), (6) and (44) according to the present invention, respectively.
Further, Sample 304 was prepared in the same manner as described for Sample 202 of Example 2 except ExY-15 used in the twelfth layer was substituted with an equipmolar amount of Compound (18) according to the present invention.
These samples were processed using Processing Steps (I) to (III) as shown in Example 2 and the amount of remaining silver of each sample was determined. The results obtained were almost same as that of Sample 207 in Example 2.

EXAMPLE 4

Samples 401 to 410 were prepared in the same manner as described for Samples 201 to 210 of Example 2 except ExC-2 and ExC-4 used in the third layer were substituted with an equimolar amount (which is a total mole number of ExC-2 and ExC-4) of Comparative Compound (A) and ExY-13 used in the ninth, eleventh, and twelfth layers was substituted with an equimolar amount of Comparative Compound (B), respectively.
These samples were processed using Processing Steps (I) to (III) as shown in Example 1 and the amount of remaining silver of each sample was determined. The results are shown in Table 3 below.
The results show that the remaining silver of Samples 401 to 410 in Processing Steps (I) to (III) is larger than that of Samples 201 to 210, which is particularly remarkable in Samples 406 to 410. The facts shows that the remaining silver changes in the case where the compound capable of releasing a bleach accelerating agent of the present invention is used, depending on the kind of the DIR coupler. A photogrpahic material which is excellent in desilverizibility can be obtained by the co-use of the DIR coupler represented by formula (Y).
