Description:
FIELD OF THE INVENTION 
     The present invention relates to a color photographic light-sensitive material containing a 2-equivalent magenta coupler and, particularly, to a method for prevention of stain which occurs during development processing of a color photographic light-sensitive material containing a 2-equivalent magenta coupler. 
     BACKGROUND OF THE INVENTION 
     Various pyrazolone derivatives are known as a magenta dye forming coupler (hereinafter referred to as a magenta coupler). However, pyrazolone derivatives generally used for photographic light-sensitive materials are 4-equivalent couplers. Such compounds theoretically require the development of 4 moles of silver halide for forming 1 mole of a dye by reacting with an aromatic primary amine developing agent. On the contrary, pyrazolones having an active methylene group substituted by a group which can be released by oxidative coupling with an oxidation product of the primary amine developing agent require development of only two moles of silver halide. In addition, the 4-equivalent pyrazolone derivatives have a low color forming efficiency (conversion of the coupler into the dye) and form generally only a 1/2 mole or so of the dye per mole of the coupler. 
     As a means for improving the color forming efficiency by decreasing the amount of silver halide required for development, utilization of 2-equivalent pyrazolone magenta couplers has been proposed. Examples of pyrazolone derivatives which release an oxygen atom include compounds having an aryloxy group in the 4-position of 5-pyrazolone as described in U.S. Pat. No. 3,419,391 and compounds having an acyloxy group as described in U.S. Pat. Nos. 3,311,476 and 3,926,631. 
     Examples of pyrazolone derivatives which release a nitrogen atom include compounds having an imidazolyl group, a pyrazolyl group or a triazolyl group in the 4-position of 5-pyrazolone as described in U.S. Pat. Nos. 4,076,533 and 4,241,168. 
     Further, examples of pyrazolone derivatives which release a sulfur atom include compounds having a heterocyclic thio group or an arylthio group in the 4-position of 5-pyrazolone as described in U.S. Pat. No. 3,227,554, compounds having a thiocyano group in the 4-position of 5-pyrazolone as described in U.S. Pat. No. 3,214,437 and compounds having a dithiocarbamate group in the 4-position of 5-pyrazolone as described in U.S. Pat. No. 4,032,346. These compounds are advantageous in that most of them can be synthesized from 4-equivalent pyrazolones by one step. Also, these compounds are advantageous in view of photographic sensitivity and equivalency. It has been found that compounds having a 2-alkoxyarylthio group in the 4-position of 5-pyrazolone have exceptionally superior properties among couplers of type which release an arylthio group. More specifically, these compounds are described in U.S. Pat. No. 4,351,897. In addition, magenta color images formed from the couplers having a 2-alkoxyarylthio group have good fastness to light, while the light fastness of magenta color images formed from conventional couplers having an arylthio group is remarkably inferior. 
     However, with these 2-equivalent magenta couplers, a disadvantageous property whereby stains (increase in color density in unexposed areas) are formed by development processing is eliminated to a certain extent but the elimination is still insufficient. 
     The stains occurring in unexposed areas of silver halide color photographic light-sensitive material are undesirable since they are the definite factor in determining whether the whiteness of the non-image areas is good or bad. Further, the stains adversely affect the color turbidity of the images and injure their visual sharpness. Particularly, in case of reflective photographic materials, for example, photographic color papers, the reflective density of the stains is theoretically emphasized so that it becomes several times as high as the transmission density. Therefore, the stains are very important factors since a slight degree of stain can injure image quality. 
     The stains in the silver halide color photographic light-sensitive materials are roughly classified to four groups depending on the cause of the stain occurrence. First is a stain which is formed after the production of the photographic light-sensitive material and before the processing thereof due to heat or humidity. Second is a stain due to a development fog of silver halide. Third is a stain based on color contamination due to color couplers in a development processing solution (for example, aerial fog, etc.) or a stain due to a dye formed by the reaction with coupler of an oxidized developing agent which is formed by oxidation of a developing agent remaining in the silver halide emulsion layer by a bleach solution or oxygen in the air, etc., (for example, bleaching stain, etc.). And fourth is a stain based on changes in photographic materials after development processing with the passage of time due to light, humidity or heat. The stains due to the development processing of the photographic materials containing 2-equivalent magenta couples according to the present invention relate to the third and fourth stains described above. 
     A more difficult problem is that it is unusual to newly prepare a solution for the development processing before every development processing. In practice, the solution is employed by replenishing a developing solution in an amount depending on an amount of photographic materials developed. However, a composition of the solution cannot be maintained only by the replenishment of the components which are consumed by development. 
     In general, a solution for development processing includes a color developing solution, a stopping solution, a bleaching solution, a fixing solution or a bleach-fixing (blixing) solution, etc. Since the processing temperature is maintained at a high temperature such as from 31° C. to 43° C., the compositions of the processing solutions are changed by several factors such that the developing agent, etc., is subjected to decomposition for a long period of time or to oxidation when brought in contact with the air, that the components contained in the photographic light-sensitive materials are dissolved out and accumulated in the solution during the processing of the photographic light-sensitive materials, and that a processing solution is taken into the following bath by attaching with the photographic material. Thus, the processing solution becomes the so-called running solution. To eliminate such problems, a replenishment procedure in which chemicals lacked are supplementarily added to the solution and a regeneration procedure in which desirable components are removed are carried out. However, such procedures are still incomplete. 
     The photographic light-sensitive materials containing 2-equivalent magenta couplers have a large tendency to form stains in the running solution. However, the occurrence of such stains cannot be prevented by techniques heretofore known. A known method for preventing such stains involves the incorporation of a reducing agent, particularly, an alkylhydroquinone (for example, those as described in U.S. Pat. Nos. 3,935,016 and 3,960,570) into a photographic light-sensitive material, particularly, an emulsion layer wherein the stains are formed is effective. It is also known that a chroman, a coumaran (for example, those as described in U.S. Pat. No. 2,360,292), a phenol type compound (for example, those as described in Japanese Patent Application (OPI) No. 9949/76 (the term &#34;OPI&#34; as used herein refers to a &#34;published unexamined Japanese patent application&#34;)), etc., are effective. Furthermore, a sulfinic acid type polymer is known as being effective as described in U.S. Pat. No. 4,352,873. However, these known techniques cannot provide sufficiently good effects against the processing stain due to 2-equivalent magenta couplers, in particular, the processing stain owing to the exhausted solution, while a little effect is recognized. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a method for preventing the occurrence of stain when a photographic light-sensitive material containing a 2-equivalent magenta coupler is subjected to development processing, and particularly, a method for completely preventing the occurrence of stain in a solution for development processing under the running condition. 
     Another object of the present invention is to provide a photographic light-sensitive material in which a 2-equivalent magenta coupler is used and an amount of silver contained is reduced and which has good sharpness and an excellent property of development processing.

     The compound represented by the general formula (II) is preferably rather contained in the different layer from that containing the compound represented by the general formula (I) than in the same layer as that containing the compound represented by the general formula (I). 
     Various methods can be used in order to disperse the compound represented by the general formula (I) and the compound represented by the general formula (II) into hydrophilic colloid layers.

     The present invention can be applied to a multilayer multicolor photographic light-sensitive material comprising at least two layers having different spectral sensitivities on a support. The multilayer color photographic light-sensitive material generally has at least a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a blue-sensitive emulsion layer on the support. The order of these layers may be suitably varied as occasion demands. Generally, the red-sensitive emulsion layer contains a cyan forming coupler, the green-sensitive emulsion layer contains a magenta forming coupler, and the blue-sensitive emulsion layer contains a yellow forming coupler.

     As a colored coupler, it is possible to use those described, for example, in U.S. Pat. Nos. 3,476,560, 2,521,908 and 3,034,892, Japanese Patent Publication Nos. 2016/69, 22335/63, 11304/67 and 32461/69, Japanese Patent Application (OPI) Nos. 26034/76 and 42121/77, and West German Patent Application (OLS) No. 2,418,959, etc. 
     As a DIR coupler, it is possible to use those described, for example, in U.S. Pat. Nos. 3,227,554, 3,617,291, 3,701,783, 3,790,384 and 3,632,345, West German Patent Application (OLS) Nos. 2,414,006, 2,454,301 and 2,454,329, British Pat. No. 953,454, Japanese Patent Application (OPI) Nos. 69624/77 and 122335/74 and Japanese Patent Publication No. 16141/76, etc. 
     In addition to a DIR coupler, the photographic light-sensitive material may contain a compound which releases a development inhibitor at development. For example, those described in U.S. Pat. Nos. 3,297,445 and 3,379,529, West German Patent Application (OLS) No. 2,417,914 and Japanese Patent Application (OPI) Nos. 15271/77 and 9116/78, etc., can be used. 
     Two or more of the above-described couplers may be contained in the same layer. Two or more layers may contain the same compound. 
     These couplers are added generally in an amount of from 2×10 -3  mol to 5×10 -1  mol, and preferably from 1×10 -2  mol to 5×10 -1  mol, per mol of silver in the emulsion layer. 
     The silver halide emulsion used in the present invention can be prepared by using processes described in P. Glafkides, Chimie et Physique Photographique (published by Paul Montel Co., 1967); G. F. Duffin, Photographic Emulsion Chemistry (published by The Focal Press, 1966); V. L. Zelikman et al., Making and Coating Photographic Emulsion (published by The Focal Press, 1964); etc. Namely, any of an acid process, a neutral process and an ammonia process may be used. Further, a single jet process, a double jet process, or a combination thereof can be used for reacting a soluble silver salt with a soluble halide. 
     A process for forming particles in the presence of excess silver ion (the so-called reverse mixing process) can be used, too. As one double jet process, it is possible to use a process wherein the liquid phase for forming silver halide is kept at a definite pAg, namely, the so-called controlled double jet process. According to this process, a silver halide emulsion having a regular crystal form and nearly uniform particle size can be obtained. 
     Two or more silver halide emulsions prepared separately may also be blended. 
     In the step of formation of silver halide particles or the step of physical ripening, a cadmium salt, a zinc salt, a lead salt, a thallium salt, an iridium salt or a complex salt thereof, a rhodium salt or a complex salt thereof, an iron salt or a complex salt thereof, etc., may be added thereto. 
     The photographic emulsion used in the present invention may be spectrally sensitized by methine dyes or others. Examples of dyes used include a cyanine dye, a merocyanine dye, a complex cyanine dye, a complex merocyanine dye, a holopolar cyanine dye, a hemicyanine dye, a styryl and a hemioxonol dye. A particularly useful dye is a dye belonging to the classes of a cyanine dye, a merocyanine dye, and a complex merocyanine dye. In these dyes, it is possible to utilize any basic heterocyclic nucleus conventionally utilized for a cyanine dye. Namely, it is possible to utilize 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 pyridine nucleus; the above-described nuclei to which an alicyclic hydrocarbon ring is fused; and the above-described nuclei to which an aromatic hydrocarbon ring is fused, namely, 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, a quinoline nucleus, etc. These nuclei may have substituents on the carbon atoms thereof. 
     In the merocyanine dye and the complex merocyanine dye, it is possible to utilize, as a nucleus having a ketomethylene structure, a 5- to 6-member heterocyclic nucleus such as a pyrazolin-5-one nucleus, a thiohydantoin nucleus, a 2-thioxazolidin-2,4-dione nucleus, a thiazolidine-2,4-dione nucleus, a rhodanine nucleus, a thiobarbituric acid nucleus, etc. 
     Examples of useful sensitizing dyes include those described in German Pat. No. 929,080, U.S. Pat. Nos. 2,231,658, 2,493,748, 2,503,776, 2,519,001, 2,912,329, 3,656,959, 3,672,897, 3,694,217, 4,025,349 and 4,046,572, British Pat. No. 1,242,588 and Japanese Patent Publication Nos. 14030/69 and 24844/77. 
     These sensitizing dyes may be used alone, but a combination of them may be used, too. The combination of the sensitizing dyes is frequently used for the purpose of supersensitization. Typical examples thereof have been described in U.S. Pat. Nos. 2,688,545, 2,977,229, 3,397,060, 3,522,052, 3,527,641, 3,617,293, 3,628,964, 3,666,480, 3,672,898, 3,679,428, 3,703,377, 3,769,301, 3,814,609, 3,837,862 and 4,026,707, British Pat. Nos. 1,344,281 and 1,507,803, Japanese Patent Publication Nos. 4936/68 and 12375/78 and Japanese Patent Application (OPI) Nos. 110618/77 and 109925/77. 
     The emulsion may contain a dye which does not have a spectral sensitization function, or a substance showing supersensitization which does not substantially absorb visible rays together with the sensitizing dye. For example, the emulsion may contain an aminostilbene compound substituted with a nitrogen-containing heterocyclic group (for example, those described in U.S. Pat. Nos. 2,933,390 and 3,635,721), an aromatic acid-formaldehyde condensed product (for example, those described in U.S. Pat. No. 3,743,510), a cadmium salt and an azaindene compound. Combinations as described in U.S. Pat. Nos. 3,615,613, 3,615,641, 3,617,295 and 3,635,721 are particularly useful. 
     For the purpose of increasing sensitivity, increasing contrast, or accelerating development, the photographic emulsion layer of the photographic light-sensitive material of the present invention may contain, for example, polyalkylene oxide or a derivative thereof such as an ether, an ester or an amine, etc., a thioether compound, a thiomorpholine, a quaternary ammonium salt, a urethane derivative, a urea derivative, an imidazole derivative and a 3-pyrazolidone, etc. For example, it is possible to use compounds as described in U.S. Pat. Nos. 2,400,532, 2,423,549, 2,716,062, 3,617,280, 3,772,021 and 3,808,003 and British Pat. No. 1,488,991, etc. 
     In the photographic light-sensitive material produced according to the present invention, the hydrophilic colloid layer may contain a water-soluble dye as a filter dye or for other purposes such as prevention of irradiation. Examples of such dyes include an oxonol dye, a hemioxonol dye, a styryl dye, a merocyanine dye, a cyanine dye, and an azo dye. Among them, an oxonol dye, a hemioxonol dye and a merocyanine dye are particularly useful. Specific examples of such dyes capable of being used include those described in British Pat. Nos. 584,609 and 1,177,429, Japanese Patent Application (OPI) Nos. 85130/73, 99620/74, 114420/74 and 108115/77, and U.S. Pat. Nos. 2,274,782, 2,533,472, 2,956,879, 3,148,187, 3,177,078, 3,247,127, 3,540,887, 3,575,704, 3,653,905, 3,718,472, 4,071,312 and 4,070,352. 
     In carrying out the present invention, known agents for preventing color fading may be used. Further, such dye image stabilizers in the present invention may be used alone, or two or more of them may be used together. Examples of the known agents for preventing color fading include a hydroquinone derivative as described in U.S. Pat. Nos. 2,360,290, 2,418,613, 2,675,314, 2,701,197, 2,704,713, 2,728,659, 2,732,300, 2,735,765, 2,710,801 and 2,816,028, British Pat. No. 1,363,921, etc., a gallic acid derivative as described in U.S. Pat. Nos. 3,457,079, 3,069,262, etc., p-alkoxyphenol as described in U.S. Pat.

Nos. 3,432,300, 3,573,050, 3,574,627 and 3,764,337 and Japanese Patent Application (OPI) Nos. 35633/77, 147434/77 and 152225/77, and a bisphenol as described in U.S. Pat. No. 3,700,455. 
     In the photographic light-sensitive material produced according to the present invention, it is preferred that the hydrophilic colloid layer contain an ultraviolet ray absorbing agent. For example, it is possible to use a benzotriazole compound substituted with an aryl group (for example, those described in U.S. Pat. No. 3,533,794), a 4-thiazolidone compound (for example, those described in U.S. Pat. Nos. 3,314,794 and 3,352,681), a benzophenone compound (for example, those described in Japanese Patent Application (OPI) No. 2784/71, a cinnamic acid ester compound (for example, those described in U.S. Pat. Nos. 3,705,805 and 3,707,375), a butadiene compound (for example, those described in U.S. Pat. No. 4,045,229), and a benzoxazole compound (for example, those described in U.S. Pat. No. 3,700,455). Further, it is possible to use those described in U.S. Pat. No. 3,499,762 and Japanese Patent Application (OPI) No. 48535/79. A coupler having an ultraviolet ray absorbing property (for example, an α-naphthol type cyan dye forming coupler) and a polymer having an ultraviolet ray absorbing property may be used, too. These ultraviolet ray absorbing agents may be mordanted on a specified layer. 
     In the photographic light-sensitive material produced according to the present invention, the photographic emulsion layer and other hydrophilic colloid layers may contain a whitening agent such as a stilbene, triazine, oxazole, or coumarin compound. They may be water-soluble. Further, a water-insoluble whitening agent may be used in a dispersed state. Specific examples of the fluorescent whitening agents include those described in U.S. Pat. Nos. 2,632,701, 3,269,840 and 3,359,102, British Pat. Nos. 852,075 and 1,319,763, etc. 
     The photographic processing of the photographic light-sensitive material of the present invention can be carried out by any known process. Known processing solutions can be used. The processing temperature is selected, generally, from 18° C. to 50° C., but a temperature of lower than 18° C. or higher than 50° C. may be used. 
     The color developing solution is generally composed of an alkaline aqueous solution containing a color developing agent. As the color developing agent, known primary aromatic amine developing agent can be used, examples of which include a phenylenediamine (for example, 4-amino-N,N-diethylaniline, 3-methyl-4-amino-N,N-diethylaniline, 4-amino-N-ethyl-N-β-hyroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 4-amino-3-methyl-N-ethyl-N-β-methoxyethylaniline, etc.).

     In the present invention, the color photographic light-sensitive material may contain a color developing agent. The color developing agent can be incorporated as a precursor or a complex salt as described in U.S. Pat. Nos. 2,478,400, 3,342,597, 3,342,599, 3,719,492 and 4,214,047, Japanese Patent Application (OPI) Nos. 135628/78, 79035/79, 6235/81, 54430/81 and 89735/81, Research Disclosure, No. 13924, No. 14850 and No. 15159, etc. In such a case, it is possible to treat the color photographic light-sensitive material with an alkaline bath instead of a color developing bath. 
     After carrying out the color development or the alkaline treatment, the photographic emulsion layers are generally subjected to bleaching. The bleaching may be carried out simultaneously with fixing or may be carried out separately. As the bleaching agent, a compound of a polyvalent metal such as iron (III), cobalt (III), chromium (VI) or copper (II), etc., a peracid, a quinone, a nitroso compound, etc., can be used. For example, it is possible to use a ferricyanide, a bichromate, and an organic complex salt of iron (III) or cobalt (III), for example, a complex salt of an aminopolycarboxylic acid such as ethylenediaminetetraacetic acid, nitrilotriacetic acid or 1,3-diamino-2-propanol tetraacetic acid, etc., or an organic acid such as citric acid, tartaric acid, malic acid, etc.; a persulfate; a permanganate; nitrosophenol; etc. Among them, potassium ferricyanide, (ethylenediaminetetraacetato)iron (III) sodium complex and (ethylenediaminetetraacetato)iron (III) ammonium complex are particularly useful. (Ethylenediaminetetraacetato)iron (III) complexes are useful for both a bleaching solution and a mono-bath bleach-fixing solution. 
     To the bleaching solution or the bleach-fixing solution, it is possible to add a bleaching accelerator as described in U.S. Pat. Nos. 3,042,520 and 3,241,966, and Japanese Patent Publication Nos. 8506/70 and 8836/70 or a thiol compound as described in Japanese Patent Application (OPI) No. 65732/78, and various other additives. 
     The photographic light-sensitive material according to the present invention may be processed with the developing solution supplemented or controlled by the methods as described in Japanese Patent Application (OPI) Nos. 84636/76, 119934/77, 46732/78, 9626/79, 19741/79, 37731/79, 1048/81, 1049/81 and 27142/81, etc.

     From the results as shown in Table 1 above, it is understood that the magenta stain density is remarkably reduced with Samples D, E, G and H according to the present invention. On the contrary, when the compound represented by the general formula (II) was incorporated into a closer layer than a layer containing the magenta coupler to the support (i.e., Layer 1 to Layer 5), the effect obtained was very small (see Samples F and I). Further, the stain density was hardly reduced by incorporation of the comparison compound into the layer.

     From the results as shown in Table 2 above, it is understood that the magenta stain density is remarkably reduced with Samples M, N, P and Q according to the present invention. On the contrary, when the same compounds were incorporated into Layer 2 as in Samples O and R, the magenta stain density was hardly reduced. Further, when the comparison compounds were used, the effect for reducing magenta stain was insufficient even if they were incorporated into Layer 6. In addition, the gradation of the green-sensitive layer and the red-sensitive layer became soft and color turbidity occurred. Therefore, satisfactory photographic properties could not be obtained. 
     While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
