Title: Silver halide photographic material

Description:
FIELD OF THE INVENTION 
     This invention relates to a silver halide photographic material and, more particularly, to a silver halide photographic material having improved image stability and improved stability in its preparation. 
     More particularly, it relates to a photographic light-sensitive material which provides a photographic image having improved antifungal and antibacterial properties. 
     BACKGROUND OF THE INVENTION 
     Many bactericides and antifungal agents used for killing bacteria and fungi are generally known, as described in, for example, Biseibutsu no Mekkin, Sakkin, Bobai Gijutsu (&#34;Techniques of Sterilization, Pasteurization, and Fungicides of Microorganisms&#34;) compiled by Eisei Gijustu-kai (&#34;Saninitary Technology Society&#34;) (published in 1982). In the field of silver halide photography, however, relatively few agents are known, and they have undesirable side effects such as reduction in photographic sensitivity. There are few agents which show satisfactory bactericidal and fungicidal effects when used in a small amount. For example, JP-A-60-263938 (The term &#34;JP-A&#34; as used herein means an &#34;unexamined published Japanese Publication&#34;) discloses compounds effective as antifungal agent. JP-B-58-48892 (the term &#34;JP-B&#34; as used herein means an &#34;examined Japanese Patent publication&#34;) discloses various compounds as antibacterial agents with some efficacy. However, these agents are still insufficient. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a silver halide photographic material with sufficient antifungal and antibacterial properties, without adversely affecting the silver halide light-sensitive material or silver halide photographic image formed after development processing, and to prevent deterioration of photographic pictures caused by generation or growth of fungi and bacteria. 
     It has now been found that this and other objects of the present invention can be attained by a silver halide photographic material composed of a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the material contains the combination of (i) at least one compound represented by formula (I) and (ii) at least one compound represented by formulae (II) and/or (III): ##STR7## wherein R 1  represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group, X represents a halogen atom, a nitro group, a hydroxyl group, a cyano group, a lower alkyl group, a lower alkoxy group --COR 2 , ##STR8## or --SO 3  M; R 2  represents hydrogen, --OM, a lower alkyl group, an aryl group, an aralkyl group, a lower alkoxy group, an aryloxy group, an aralkyloxy group or ##STR9## R 3  and R 4 , which may be the same or different, each represents hydrogen, a lower alkyl group, an aryl group, an aralkyl group, --COR 7  or --SO 2  R 7  ; R 5  and R 6 , which may be the same or different, each represents hydrogen, a lower alkyl group, an aryl group or an aralkyl group; R 7  represents a lower alkyl group; an aryl group or an aralkyl group; M represents hydrogen, an alkali metal atom or a monovalent cation; m represents 0 or an integer of 1 to 4; n represents 0 or an integer of 1 to 4; and Z represents an atomic group necessary for forming a thiazolyl ring; ##STR10## wherein R 8  represents a lower alkylene group; X is the same as X in formula (I); p represents 0 or 1, and q represents 0 or an integer of 1 or 5; ##STR11## wherein R 9  represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a heterocyclic group, ##STR12## R 10  and R 11 , which may be the same or different, each represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a cyano group, a heterocyclic group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted alkylsulfonyloxy group or a substituted or unsubstituted alkylsulfonyl group; R 10  and R 11  may be linked to form an aromatic ring; and R 12  and R 13 , which may be the same or different, each represents hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group.

If necessary, various preservatives such as hydroxylamine, diethylhydroxylamine, hydrazine sulfites, phenylsemicarbazides, triethanolamine, catecholsulfonic acids, triethylenediamine (1,4-diazabicyclo(2,2,2)octane), etc.; organic solvents such as ethylene glycol, diethylene glycol, etc.; development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, amines, etc.; dye-forming couplers; competitive couplers; fogging agents such as sodium borohydride; auxiliary developing agents such as 1-phenyl-3-pyrazolidone; viscosity-imparting agents; various chelating agents represented by aminopolycarboxylic acids, aminopolyphosphonic acid, alkylphosphonic acids, and phosphonocarboxylic acids such as 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&#39;N&#39;-tetramethylenephosphonic acid, ethylenediamine-di(o-hydroxyphenylacetic acid) and salts thereof, may be added to the color developer. 
     In conducting reversal processing, usually black-and-white development is conducted before color development. This black-and-white developer includes known black-and-white developing agents such as dihydroxybenzenes (for example, hydroquinone), 3-pyrazolidones (for example, 1-phenyl-3-pyrazolidone) and aminophenols (for example, N-methyl-p-aminophenol) alone or as a combination thereof. 
     These color developer and black-and-white developer generally have a pH of 9 to 12. These developers are replenished generally in amounts of up to 3 liters per m 2  of light-sensitive materials, though depending upon the kind of color photographic light-sensitive materials to be processed. The replenishing amount may be reduced to not more than 500 ml by decreasing the bromide ion concentration in the replenisher. In the case of decreasing the replenishing amount, contact area between the solution and the air within the processing tank be preferably minimized to thereby prevent vaporization and air oxidation of the solution. In addition, the replenishing amount may also be decreased by employing means of depressing accumulation of bromide ion in the developer. 
     Color-developed photographic emulsion layers are usually bleached. Bleaching may be conducted independently or simultaneously with fixing (bleach-fixing). In order to promote the processing, bleach-fixing may be conducted after bleaching. Further, it is possible to use two continuous bleach-fixing baths, to fix before bleach-fixing or to bleach-fix after bleach-fixing, as desired. As the bleaching agent, compounds of polyvalent metals such as iron(III), cobalt(III), chromium (VI), copper(II), etc., peracids, quinones, nitro compounds, and the like are used. As typical bleaching agents, ferricyanides; dichromates; organic complex salts of iron(III) or cobalt(III), for example, complex salts of aminopolycarboxylic acids such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid and glycol ether diaminetetraacetic acid or of organic acids such as citric acid, tartaric acid and malic acid; persulfates; bromide acid salts; permanganates; nitrobenzenes; etc. may be used. Of these, iron (III) aminopolycarboxylates including iron (III) ethylenediaminetetraacetate and persulfates are preferred in view of rapid processing and prevention of environmental pollution. Further, iron (III) aminopolycarboxylate complex salts are particularly useful in both an independent bleaching solution and a bleach-fixing solution. 
     The bleaching or bleach-fixing solution containing these iron(III) aminopolycarboxylate complex salts usually has a pH of 5.5 to 8, but may have a lower pH for accelerating the processing. 
     A bleach accelerator may be used in the bleaching solution, bleach-fixing solution, or pre-baths thereof. As specific examples of useful bleach accelerators, there are illustrated mercapto group- or disulfido group-containing compounds described in, for example, U.S. Pat. No. 3,893,858, West German Pat. Nos. 1,290,812 and 2,059,988, JP-A-53-32736, JP-A-53-57831, JP-A-53-37418, JP-A-53-72623, JP-A-53-95630, JP-A-53-95631, JP-A-53-10423, JP-A-53-124424, JP-A-53-141623, JP-A-53-28426, and Research Disclosure, No. 17129 (Jul., 1978); thiazolidine derivatives described in JP-A-50-140129; thiourea derivatives described in JP-B-45-8506, JP-A-52-20832, JP-A-53-32735, U.S. Pat. No. 3,706,561, etc.; iodides described in West German Pat. No. 1,127,715, and JP-A-58-16235; polyoxyethylenes described in West German Pat. Nos. 966,410 and 2,748,430; polyamines described in JP-B-45-8836; compounds described in JP-A-49-42434, JP-A-49-59644, JP-A-53-94927, JP-A-54-35727, JP-A-55-26506, JP-A-58-163940; and bromide ion. Of these, mercapto group- or disulfido group-containing compounds are preferable due to their great accelerating effect, and compounds described in U.S. Pat. No. 3,893,858, West German Pat. No. 1,290,812 and JP-A-53-95630 are particularly preferred. In addition, those compounds which are described in U.S. Pat. No. 4,552,834 are also preferred. These beach accelerators may be incorporated into the photographic materials. 
     These bleach accelerators are particularly effective in bleach-fixing color light-sensitive materials for photographing use. 
     Fixing agents include, for example, thiosulfates, thiocyanates, thioether compounds, thioureas and a large amount of an iodide salt. Of these, thiosulfates are generally used, with ammonium thiosulfate being most widely used. As preservatives for the bleach-fixing solution, sulfites, bisulfites or carbonyl-bisulfite adducts are preferred. 
     After removal of silver, the silver halide color photographic material of the present invention is generally subjected to a water-washing step and/or stabilizing step. The amount of water used in the water-washing step may be selected in a wide range depending upon the characteristics of the light-sensitive material (resulting from, for example, materials such as couplers), end-use, temperature of the washing water, number (step number) of washing tanks, manner of replenishment (countercurrent manner or direct current manner), and other various conditions. Of these, the number of water-washing tanks and the amount of washing water can be determined according to the method described in Journal of the Society of Motion Picture and Television Engineers vol. 64, pp. 248-253 (May, 1955). 
     The multistage countercurrent manner described in the above-described publication permits to marked reduction of the amount of washing water but since the standing time of water within the tanks is prolonged, there arises a problem of adhesion of floating matter produced as a result of growth of bacteria. In order to solve the problem in processing the color light-sensitive material of the present invention, the technique of reducing the level of calcium ion and magnesium ion described in JP-A-62-288838 may be effectively employed. In addition, chlorine-containing bactericides (for example, sodium chloroisocyanurate and bactericides described in Bokin Bobai no Kagaku (&#34;Chemistry of bactericides and fungicides&#34;) written by Hiroshi Horiguchi, Biseibutsu no Mekkin, Sakkin, Bobai Gijutsu  (&#34;Techniques of Sterilization, Pasteurization, and Fungicides of Microorganisms&#34;) compiled by Eisei Gijustukai (&#34;Sanitary Technology society&#34;) and Bokin Bobaizai Jiten (&#34;Book of Bactericides and Fungicides&#34;) compiled by Nippon Bokin Bobai Gakkai (&#34;Japan Bactericide and Fungicide Society&#34;), such as benzotriazoles may be used. 
     The washing water to be used for processing the light-sensitive material of the present invention has a pH of 4 to 9, preferably 5 to 8. The washing temperature and washing time may be variously selected depending upon the characteristics and end-use of light-sensitive materials, but, as a general guide, a washing temperature of 15° to 45° C. and a washing time of 20 seconds to 10 minutes is typical, with a washing temperature of 25° to 40° C. and a washing time of 30 seconds to 5 minutes being preferred. Further, the light-sensitive material of the present invention may be directly processed with a stabilizing solution in place of the above-described washing with water. In such stabilizing processing, all known techniques described in JP-A-57-8543, JP-A-58-14834 and JP-A-60-220345 may be employed. 
     In addition, stabilizing processing may be conducted subsequent to the above-described water-washing processing. For example, a stabilizing bath containing formalin and a surfactant can be used as a final bath for processing color light-sensitive materials for photographic use. To this stabilizing bath may also be added various chelating agents and antifungal agents. 
     An over-flow solution produced as a result of replenishment of the washing water and/or stabilizing solution may be re-used in other steps such as silver-removing step. 
     Color developing agents may be incorporated in the silver halide color photographic material of the present invention for the purpose of simplifying and accelerating the processing. Various precursors of the color developing agents to be incorporated are preferably used. For example, These include indoaniline compounds described in U.S. Pat. No. 3,342,597; Schiff base type compounds described in U.S. Pat. No. 3,342,599 and Research Disclosure Nos. 14,850 and 15,159; aldol compounds described in Research Disclosure No. 13,924; metal salt complexes described in U.S. Pat. No. 3,719,492; and urethane compounds described in JP-A-53-135628. 
     The silver halide color photographic material of the present invention may contain, if necessary, various 1-phenyl-3-pyrazolidones for the purpose of accelerating color development. Typical examples thereof are described in, for example, JP-A-56-64339, JP-A-57-144547 and JP-A-58-115438. 
     Various processing solutions in the present invention are used at temperatures of 10° C. to 50° C. Temperatures of 33° C. to 38° C. are standard, but higher temperatures may be employed for accelerating processing and shortening processing time, or lower temperature may be employed to improve image quality or stability of processing solutions. In addition, processing using cobalt intensification or hydrogen peroxide intensification described in West German Pat. No. 2,226,770 or U.S. Pat. No. 3,674,499 may be conducted for saving silver of light-sensitive materials. 
     Growth of fungi and bacteria can be markedly prevented by incorporation of the compound represented by the general formula (I) and the compound represented by the general formula (II) and/or (III) in photographic light-sensitive materials. This effect is suprisingly greater than that obtained by independently using the compounds of the general formulae (I), (II) and (III). 
     The present invention is now illustrated in more detail with reference to the following examples which, however, are not to be construed as limiting the scope of the present invention in any way. Unless otherwise indicated, all parts, percents and ratios are by weight.

     The tests were conducted as follows. 
     Of the thus prepared samples, unexposed Samples 101 to 109 were subjected to the testing for antifungal properties. Fungi having grown in color negatives were cultured in potato·dextrose agar medium, and spores were collected to prepare a spore-suspended solution containing about 1×10 6  spores/ml. 0.5 ml of this spore-suspended solution was dropped onto each sample, then the sample was kept at 28° C. and 95% humidity to observe the growing state of fungi. Results of the observation are shown in Table 1. Rating criteria are given in Table 2. 
     Anitbacterial properties were rated according to Table 3, after leaving the samples for 24 hours or 48 hours at 40° C. and culturing at 40° C. for 24 hours using EAGICULT TTC bacteria-testing plates made by ORION DIAGNOSTICA CO. 
     It is seen from the results that samples 105 to 109 were clearly better than samples 102 to 104 in antifungal and antibacterial properties. 
     EXAMPLE 2 
     Multi-layer photographic printing paper as Sample 201 composed of a polyethylene-double laminated paper support having provided thereon the following layer structure was prepared. Coating solution were prepared as follows. 
     27.2 cc of ethyl acetate and 7.7 cc (8.0 g) of a high-boiling point solvent (Solv-1) were added to a mixture of 10.2 g of yellow coupler (ExY-1), 9.1 g of yellow coupler (ExY-2) and 4.4 g of color image stabilizer (Cpd-2) to prepare a solution. This solution was emulsified and dispersed in 185 cc of a 10% gelatin aqueous solution containing 8 cc of 10% sodium dodecylbenzenesulfonate. This emulsion dispersion was mixed with emulsion EM1 and EM2 to adjust the gelatin concentration to the following formulation, to prepare a coating solution for a first layer. Coating solution for forming second to seventh layers were also prepared in the same manner as the coating solution for forming a first layer. As a gelatin hardener for each layer, 2,4-dichloro-6-hydroxy-s-triazine sodium salt was used. 
     In addition, (Cpd-1) was used as a thickening agent for the coating solutions. 
     Layer Structure 
     The compositions of the respective layers are shown below, coated amounts being shown as (g/m 2 ), and amounts of coated silver emulsions being shown as silver amounts.

     Water for Washing 
     Tap water was passed through a mixed bed-type column filled with an H-type strongly acidic cation-exchange resin (Amberlite IR-120B; made by Rohm &amp; Haas Co.) and an OH-type strongly basic anion-exchange resin (Amberlite IRA-400; made by Rohm &amp; Haas Co.) to thereby reduce calcium and magnesium ion concentrations to 3 mg/liter or less, followed by adding to the thus-processed water 20  mg/liter of sodium dichloroisocyanurate and 150 mg/liter of sodium sulfate. This solution had a pH of between 6.5 and 7.5. 
     EXAMPLE 3 
     (1) Preparation of Light-Sensitive Silver Halide Emulsions 
     Potassium bromide and potassium iodide, and silver nitrate were added to a gelatin aqueous solution under vigorous stirring to prepare silver iodobromide (AgI=4 mol %) of thick tabular form having an average grain size of 1 μ. This was then washed with water according to a conventional precipitation process, and was subjected to chemical sensitization according to gold·sulfuric acid sensitization using chloroauric acid and sodium thiosulfate to obtain light-sensitive silver iodobromide emulsion A. Silver halide emulsions B (0.8 μ in average grain size) and C (0.6 μ in average grain size) were prepared in the same manner as silver halide emulsion A except for controlling temperature upon preparation. 
     (2) Preparation of Coated Sample 
     Sample 301 was prepared on a triacetyl cellulose support by providing in sequence layers of the following formulations from the support side. As the support, a support of 0.3 in optical density was used.
