The silver halide color photographic material provides color images having improved sharpness and color reproducibility.

Description: FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material which is excellent in sharpness and color reproducibility. BACKGROUND OF THE INVENTION In the field of color photographic light-sensitive materials based on a substractive process, it has been hitherto known to employ compounds which are capable of releasing a photographically useful group upon reaction with an oxidation product of a developing agent. Such a released, photographically useful groups include, for example, development inhibitors, fogging agents, bleach accelerating agents, dyes and fluorescent whitening agents, which are employed for their respective purposes. Exemplary methods are described in U.S. Patent 4,248,962. Couplers which release a development inhibitor from non-color forming coupler moieties which do not substantially form a dye are also known and described, for example, in U.S. Patents 3,632,345, 3,958,993, 3,928,041, 4,187,110, 4,259,437 and 4,226,934. However, these couplers described in such patents are not sufficient in view of their reaction rate with the oxidation products of developing agents, and thus further improvement has been desired. Further, couplers described in JP-A-52-82423 (the term "JP-A" as used herein means an "unexamined published Japanese patent application") have a sufficiently high coupling rate, but provide a dye having a large molecular absorption coefficient. Accordingly, they are not suitable for non-color forming couplers. Couplers capable of releasing a photographically useful group are ordinarily employed in a combination with image forming couplers. Therefore, they can be employed only for the purpose of releasing a photographically useful group other than that which forms a dye, i.e., it is not always necessary to form a dye. Specifically, couplers which are substantially non-color forming, which form a dye having a small molecular absorption coefficient, or which form a dye that is unstable and immediately decomposes can be employed in any of a blue, green or red-sensitive layer and an intermediate layer without limitation. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a silver halide color photographic material which is excellent in sharpness. Another object of the present invention is to provide a silver halide color photographic material of high sensitivity without damaging its color reproducibility and desilvering properties. Other objects of the present invention will become apparent from the following detailed description and examples. The above-described objects of the present invention can be accomplished by a silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material contains a compound represented by the following general formula (II): wherein X, Y and Z, which may be the same or different, each represents a methine group or a nitrogen atom provided that at least one of X, Y and Z is a nitrogen atom; R₁ represents a group capable of substituting on the hetero ring; R₂ represents an organic moiety; L represents a group capable of being cleaved from when the compound represented by the general formula (II) is reacted with an oxidation product of a developing agent and capable of releasing PUG after the cleavage from the methine group; PUG represents a photographically useful group; m represents an integer from 0 to 2; and n represents an integer from 0 to 4, when m or n represents 2 or more, two or more R₁'s or L's may be the same or different.

In the general formula (II), a more preferred PUG is a group providing a compound having a development inhibiting function when being released as PUG. A development inhibitor which is capable of being decomposed (or changed into) a compound having substantially no effect on photographic properties after being discharged into a color developing solution is particularly preferred. Examples of these development inhibitors include those as described in U.S. Patent 4,477,563, JP-A-60-218644, JP-A-60-221750, JP-A-60-233650 and JP-A-61-111743. Preferred examples of the development inhibitors include those represented by the following general formulas (D-1), (D-2), (D-3), (D-4), (D-5), (D-6), (D-7), (D-8), (D-9), (D-10), (D-11) and (D-12): wherein a bond indicated by * denotes the position at which the group is connected to the methine group or the linking group (L) in the general formula (II); R₁₆ represents a hydrogen atom or a substituent; e represents 1 or 2; L₃ represents a group containing a chemical bond which is capable of being cleaved in a developing solution; and Y i represents a substituent capable of generating the development inhibiting function and is selected from an aliphatic group, an aromatic group or a heterocyclic group. The development inhibitor described above which is released diffuses in a photographic layer while exhibiting the development inhibiting function and a part thereof discharges into the color developing solution. The development inhibitor discharged into the color developing solution rapidly decomposes at the chemical bond, included in L₃, to releases the group represented by Y i (for example, hydrolysis of an ester bond) upon a reaction with a hydroxy ion or hydroxylamine generally present in the color developing solution; whereby the compound changes into a compound having a large water-solubility and a small development inhibiting function, and thus the development inhibiting function substantially disappears. While R₁₆ in the above described formulae is preferably a hydrogen atom, it may also be a substituent. Representative examples of the substituent include an aliphatic group (for example, methyl, or ethyl), an aliphatic or aromatic acylamino group (for example, acetamido, or propionamido), an alkoxy group (for example, methoxy, or ethoxy), a halogen atom (for example, chlorine, or bromine), a nitro group, or an aliphatic or aromatic sulfonamido group (for example, methanesulfonamido). The linking group represented by L₃ in the above described general formulae includes a chemical bond which is cleaved in a developing solution. Suitable examples of such chemical bonds include those described in the table below. These chemical bonds are cleaved with a nucleophilic reagent such as hydroxy ion or hydroxylamine, etc. which is a component of the color developing solution. The chemical bond group shown in the table above is connected directly or through an alkylene group and/or a phenylene group with a heterocyclic moiety constituting development inhibitor or a benzene ring constituting development inhititor (in the case of benzene condensed ring) and connected directly with Y i . When the chemical bond group is connected through an alkylene group and/or a phenylene group, the alkylene group and/or phenylene group may contain an ether bond, an amido bond, a carbonyl group, a thioether bond, a sulfon group, a sulfonamido bond or a ureido bond at the divalent group. The aliphatic group represented by Y i is a hydrocarbon group having from 1 to 20 carbon atoms, preferably from 1 to 10 carbon atoms, and may be saturated or unsaturated, straight chain, branched chain or cyclic, or substituted or unsubstituted. A substituted hydrocarbon group is particularly preferred. The aromatic group represented by Y i is a substituted or unsubstituted phenyl group or a substituted or unsubstituted naphthyl group. The heterocyclic group represented by Y i is a substituted or unsubstituted four-membered to eight-membered heterocyclic group containing at least one of a sulfur atom, an oxygen atom and a nitrogen atom as a hetero atom. Specific examples of the heterocyclic groups include a pyridyl group, an imidazolyl group, a furyl group, a pyrazolyl group, an oxazolyl group, a thiazolyl group, a thiadiazolyl group, a triazolyl group, a diazolidinyl group, and a diadinyl group.

Further, the compounds according to the present invention can be added to any light-sensitive layer of appropriate sensitivity, for example, a high-sensitive layer or a low-sensitive layer. The amount of the compound represented by the general formula (II) according to the present invention to be added can be varied depending on the structure of the compound. However, it is preferred to use in a range from 1×10⁻⁶ mol to 0.5 mol, particularly from 1×10⁻⁵ mol to 1×10⁻¹ mol per mol of silver (silver halide calculated as silver and colloidal silver) present in the same layer to which it is to be added, or a layer adjacent thereto directly. The compound represented by the general formula (II) according to the present invention can be employed in a combination with a color image forming coupler in a silver halide emulsion layer. In such a case, a molar ratio of the compound according to the present invention/color image forming coupler is generally from 0.01/99.99 to 50/50, preferably from 1/99 to 30/70. Specific examples of the compounds, according to the present invention are set forth below, but the present invention should not be construed as being limited thereto. Typical synthesis examples of compounds of the present invention are illustrated below. Other compounds encompassed herein can be synthesized in a similar manner. SYNTHESIS EXAMPLE 1 Synthesis of Compound (1) Compound (1) was synthesized according to the route schematically shown below. Step (1): Synthesis of Intermediate Compound 4 56.0 g of reduced iron and 3.6 g of ammonium chloride were added to a solution of 150 ml of isopropanol, 20 ml of water and 3.6 ml of acetic acid. After the mixture was refluxed by heating for 20 minutes, 15.0 g of Compound 1 was added thereto little by little. After the completion of the addition, the mixture was refluxed for 1 hour, and then filtered while hot to remove iron. To the filtrate was added dropwise 50 ml of acetonitrile containing 22.7 g of Compound 3 dissolved therein. After the reaction, 500 ml of ethyl acetate was added to the reaction mixture and then the mixture was washed with water. The organic layer was dried, and the solvent was distilled off under reduced pressure. The residue was recrystallized from a solvent mixture of ethyl acetate and hexane to obtain 24.2 g of Intermediate Compound 4. Step (2): Synthesis of Compound (1) To 100 ml of chloroform solution, containing 20.0 g of Intermediate Compound 4 dissolved therein, was added dropwise 20 ml of chloroform solution containing 6.2 g of bromine dissolved therein, while maintaining a reaction mixture temperature of 10°C. After the reaction, water was added to the reaction mixture, in order to wash the same. Then, the chloroform layer was gradually added dropwise to 50 ml of dimethyl formamide solution containing 9.3 g of Compound 5 and 10.7 ml of triethylamine dissolved therein. After the reaction, 200 ml of ethyl acetate was added to the reaction mixture, and the mixture thoroughly washed with an aqueous solution of sodium hydrogencarbonate. After the neutralization, the organic layer was dried with magnesium sulfate, and the solvent was distilled off under a reduced pressure. The residue was recrystallized from a solvent mixture of ethyl acetate and hexane to obtain 17.6 g of desired Compound (1). SYNTHESIS EXAMPLE 2 Synthesis of Compound (5) Compound (5) was synthesized according to the route schematically shown below. Step (1): Synthesis of Intermediate Compound 9 In the same manner as described in Step (1) of Synthesis Example 1, except using 20.0 g of Compound 6, 31.5 g of Intermediate Compound 9 was obtained. Step (2): Synthesis of Compound (5) In the same manner as described in Step (2) of Synthesis Example 1 except for using 30.0 g of Intermediate Compound 9, Compound (5) was synthesized. The oily product obtained, by the conventional after-treatment, was recrystallized from a solvent mixture of dichloromethane and hexane to obtain 26.4 g of desired Compound (5). Reference Experiment Dyes 10 and 11 which were obtained from Compounds (25) and (26) according to the present invention described above were synthesized. The maximum absorption wavelength, and the molecular absorption coefficient (ε) at the maximum absorption wavelength of each dye were measured. The results are shown in Table 1. From the results shown in Table 1, it can be seen that the dyes obtained from compounds according to the present invention and the oxidation product of the developing agent, have their absorption maxima in a comparative shorter wavelength region and small molecular absorption coefficients. Accordingly, compounds of the present invention can be employed in any of a blue, green and red sensitive layer and an intermediate layer without limitation, since they act as substantially non-color forming couplers. In the photographic emulsion layer of the photographic light-sensitive material used in the present invention, a preferably employed silver halide is silver iodobromide, silver iodochloride or silver iodochlorobromide, each containing about 30 mol% or less of silver iodide. Silver iodobromide containing from about 2 mol% to about 25 mol% of silver iodide is particularly preferred. Silver halide grains in the silver halide emulsion may have a regular crystal structure, for example, a cubic octahedral or tetradecahedral structure, an irregular crystal structure, for example, a spherical or tabular structure, a crystal defect, for example, a twin plane, or a composite structure thereof. The particle size of silver halide utilized may be varied and includes particles from fine grains, having about 0.2 micron diameter or less, to large size grains, having about a 10 micron diameter of projected area. Further, polydispersed emulsion and monodispersed emulsion of the same may be used. The silver halide photographic emulsion which can be used in the present invention can be prepared using known methods, for example, those as described in Research Disclosure , No. 17643 (December, 1978), pages 22 to 23, "I. Emulsion Preparation and Types" and ibid. , No. 18716 (November, 1979), page 648, P. Glafkides, Chimie et Physique Photographique , Paul Montel (1967), G.F. Duffin, Photographic Emulsion Chemistry , The Focal Press (1966), and V.L. Zelikman et al., Making and Coating Photographic Emulsion , The Focal Press (1964). Monodispersed emulsions as described, for example, in U.S. Patents 3,574,628 and 3,655,394, and British Patent 1,413,748 are preferably used in the present invention. Further, tabular silver halide grains having an aspect ratio of about 5 or more can be employed in the present invention. The tabular grains may be easily prepared by the method as described, for example, in Gutoff, Photographic Science and Engineering , Vol. 14, pages 248 to 257 (1970), U.S. Patents 4,434,226, 4,414,310, 4,433,048 and 4,439,520, and British Patent 2,112,157. The crystal structure of silver halide grains may be uniform, composed of different halide compositions between the inner portion and the outer portion, or may have a stratified structure. Further, silver halide emulsions in which silver halide grains having different compositions are connected upon epitaxial junctions, or silver halide emulsions in which silver halide grains are connected with compounds other than silver halide, such as silver thiocyanate, or lead oxide may also be employed. Moreover, a mixture of grains having a different crystal structure may be used. The silver halide emulsion used in the present invention are usually conducted with physical ripening, chemical ripening and spectral sensitization. Various kinds of additives which can be employed in these steps are described in Research Disclosure , No. 17643, (December, 1978) and ibid. , No. 18716 (November, 1979). Concerned items 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 literatures, and concerned items thereof are summarized in the table below.

A color developing solution which can be used in development processing of the color photographic light-sensitive material according to the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine type color developing agent as a main component. As the color developing agent, while an aminophenol type compound is also useful, a p-phenylenediamine type compound is preferably employed. Typical examples of the p-phenylenediamine type compounds include 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-N-β-methoxyethylaniline, or sulfate, hydrochloride or p-toluenesulfonate thereof. Two or more kinds of color developing agents may be employed in a combination thereof, depending on the purpose. The color developing solution can ordinarily contain pH buffering agents, such as carbonates, borates or phosphates of alkali metals; and development inhibitors or anti-fogging agents such as bromides, iodides, benzimidazoles, benzothiazoles, or mercapto compounds. Further, if desired, the color developing solution may contain various preservatives such as hydroxylamine, diethylhydroxylamine, sulfites, hydrazines, phenylsemicarbazides, triethanolamine, catechol sulfonic acids, or triethylenediamine(1,4-diazabicyclo[2,2,2]octane); organic solvents such as ethyleneglycol, or diethylene glycol; development accelerators such as benzyl alcohol, polyethylene glycol, quarternary ammonium salts, or amines; dye forming couplers; competing couplers; fogging agents such as sodium borohydride; auxiliary developing agents such as 1-phenyl-3-pyrazolidone; viscosity imparting agents; and various chelating agents represented by aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, or phosphonocarboxylic acids. Representative examples of the chelating agents include ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N,N,N-trimethylenephosphonic acid, ethylenediamine-N,N,N′,N′-tetramethylenephosphonic acid, ethylenediamine-di(o-hydroxyphenylacetic acid), and salts thereof. In case of conducting reversal processing, color development is usually conducted after black-and-white development. In a black-and-white developing solution, known black-and-white developing agents, for example, dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as 1-phenyl-3 pyrazolidone, or aminophenols such as N-methyl-p-aminophenol may be employed individually or in a combination. The pH of the color developing solution or the black-and-white developing solution is usually in a range from 9 to 12. After color development, the photographic emulsion layers are usually subjected to a bleach processing. The bleach processing can be performed simultaneously with a fix processing (bleach-fix processing), or it can be performed independently from the fix processing. Further, for the purpose of a rapid processing, a processing method wherein after a bleach processing a bleach-fix processing is conducted may be employed. As bleaching agents which can be employed, ferric complex salts of aminopolycarboxylic acid (such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, or 1,3-diaminopropanetetraacetic acid) are preferred, and ferric complex salt of 1,3-diaminopropanetetraacetic acid is particularly preferred in view of rapid processing. The pH of the bleaching solution or bleach-fixing solution is preferably in a range from 3 to 7, particularly preferably from 4 to 6 in view of rapid processing. After a desilvering 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 characteristics of photographic light-sensitive materials (due to elements used therein, for example, couplers, etc.), uses thereof, temperature of washing water, a number of water washing tanks (stages), a replenishment system such as countercurrent or orderly current, or other various conditions. A relationship between a number of water washing tanks and an 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). A 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. Temperature of washing water and time for a water washing step can be variously set depending on characteristics or uses the of photographic light-sensitive materials. However, one generally selects a range of from 15 to 45°C and a period from 20 sec. to 10 min., and preferably a range of from 25 to 40°C and a period from 30 sec. 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 of known methods as described, for example, in JP-A-57-8543, JP-A-58-14834 and JP-A-60-220345 can be employed. Further, it is possible to conduct the 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 photography. To such a stabilizing bath, various chelating agents and antimolds may also be added. In the present invention, various kinds of processing solutions can be employed in a temperature range from 10 to 50°C. Although a standard temperature is from 33 to 38°C, it is possible to carry out the processing at higher temperatures in order to accelerate the processing whereby the processing time is shortened, or at lower temperatures in order to achieve improvement in image quality and to maintain stability of the processing solutions. In accordance with the present invention, silver halide color photographic material excellent in image sharpness without losing sensitivity. Further, these silver halide color photographic materials are suitable for pradical use since their sensitivity and desilvering property are not deteriorated. The present invention will be explained in greater detail with reference to the following examples, but the present invention should not be construed as being limited thereto.
