Description:
FIELD OF THE INVENTION 
     The present invention relates to a silver halide photographic light-sensitive material having a colored hydrophilic colloid layer, specifically to a silver halide photographic light-sensitive material having a hydrophilic colloid layer containing a dye which is photochemically inactive and can readily be decolored and/or eluted in a photographic processing course. 
     Further, the present invention relates to a novel oxonol compound which can be used as a pigment, a dye, a dye for a photography, a dye for a filter, a recording compound for an optical information recording medium, and a dyeing agent for an organism sample such as a cell, or pharmaceuticals or the intermediates thereof. 
     BACKGROUND OF THE INVENTION 
     In a silver halide photographic light-sensitive material, a photographic emulsion layer and the other hydrophilic colloid layers are often colored for the purpose of absorbing a light of a specific wavelength. 
     When it is necessary to control a spectral composition of a light to be incident to a photographic emulsion layer, a colored layer is usually provided on a side farther from a support than the photographic emulsion layer. Such the colored layer is called a filter layer. In the case where plural photographic emulsion layers are involved, the filter layer may be interposed therebetween. 
     For the purpose of preventing a blurring of an image, that is, halation caused by a light which is scattered in or after passing through a photographic emulsion layer and is reflected on an interface between the emulsion layer and support or a surface of a photographic material opposite to the emulsion layer side to get once again in the photographic emulsion layer, a colored layer which is called an anti-halation layer is provided. In the case where plural photographic emulsion layers are involved, the anti-halation layer is sometimes provided at the middle of them. 
     The photographic emulsion layer is colored as well in order to prevent the deterioration of an image sharpness caused by a light scattered in the photographic emulsion layer (in general, this phenomenon is called an irradiation). 
     Dyes are usually incorporated into these hydrophilic colloid layers to be colored. These dyes are required to satisfy the following conditions: 
     (1) having an appropriate spectral absorption according to use purposes; 
     (2) photochemically inactive, that is, giving no adverse affections in a chemical sense, for example, reduction of a sensitivity, degradation of a latent image and fogging, to the performances of a silver halide photographic emulsion layer; 
     (3) bleached in photographic processing steps or eluted in a processing solution or water for washing to leave no harmful color on a processed photographic light-sensitive layer; 
     (4) not diffusing from a colored layer to the other layers; and 
     (5) having an excellent storage stability in a solution or a photographic material without discoloring or fading. 
     In particular, in the case where a colored layer is a filter layer or an anti-halation layer provided on the same side of a support as a photographic emulsion layer is present, it is necessary in many cases that those layers are selectively colored and that the other layers are not substantially colored, because otherwise not only a harmful spectral effect is exerted to the other layers but also an effect as a filter layer or an anti-halation layer is reduced. Further, also in case of preventing an irradiation, selective coloring only of an aimed emulsion layer is required to prevent a similar adverse affection from being exerted to the other layers and allow a desired performance to sufficiently be revealed. However, the contact of a layer containing a dye to the other hydrophilic layers in a wet condition often permits a part of the dye to diffuse from the former to the latter. Many efforts have so far been made in order to prevent such diffusion of the dye. 
     For example, U.S. Pat. Nos. 2,548,564, 4,124,386 and 3,625,694 disclose a process in which a hydrophilic polymer having a charge opposite to a dissociated anionic dye is permitted to coexist as a mordant in a layer to localize the dye in a specific layer by means of an interaction with a dye molecule. 
     Further, U.S. Pat. Nos. 2,719,088, 2,496,841 and 2,496,843, and JP-A-60-45237 (the term &#34;JP-A&#34; as used herein means an unexamined published Japanese patent application) disclose a process in which the metal salt fine particles adsorbed thereon with a dye are used to color a specific layer. 
     Further, JP-A-55-120030, JP-A-56-12639, JP-A-55-155350, JP-A-55-155351, JP-A-63-27838, JP-A-63-197943, and JP-A-52-92716, European Patents 15,601, 323,729, 274,723, 276,566 and 299,435, WO 88/04794, and JP-A-3-223747 disclose a process in which a specific layer is colored with a water insoluble solid dye. 
     However, even the use of these improved processes still has presented a problem on a diffusion of a dye in a dye-fixing layer and a problem that a decoloring speed in a development processing is still so slow that in the case where various factors such as the acceleration of a processing, the improvement in a composition of a processing solution and the improvement in a composition of a photographic emulsion are changed, a decoloring function thereof can not necessarily be sufficiently demonstrated. 
     On the other hand, a representative dye used in such the processes includes an oxonol compound, and there are known the compounds described, for example, in The Chemistry of Synthetic Dyes, Vol. 4, p. 304 (Academic Press, 1991), Color and Constitution of Organic Molecules, p. 257 (Academic Press, 1991), JP-A-50-91627 and JP-A-60-97274, and Absorption Spectra of Dyes for Diode Lasers, p. 86 (Bunsin, 1990). 
     As described above, coloring of a hydrophilic colloid layer constituting a photographic light-sensitive material is important for controlling a spectral sensitivity and preventing blurring of an image caused by scattering of an incident ray (irradiation) and blurring of an image attributable to a reflection of a ray generated at an interface between a photographic emulsion and a support (halation). For this purpose, a barbituric acid oxonol compound having an absorption in a visible region is widely used as disclosed, for example, in U.S. Pat. No. 3,247,127, and JP-A-3-223747 and JP-A-4-352151. 
     Also in a near infrared-sensitive photographic material, the oxonol compound is added for the same purpose. However, a conventional pentamethineoxonol dye does not have an appropriate long wavelength absorption and is instable in a hydrophilic colloid layer. Accordingly, it is not appropriate. Further, a heptamethineoxonol dye provides particularly an industrial problem on achievement of the above purpose in terms of, for instance, difficulty to obtain a methine source. 
     SUMMARY OF THE INVENTION 
     Accordingly, the first object of the present invention is to provide a photographic light-sensitive material containing a dye dispersed in the form of a solid fine particle, which is designed so that a specific hydrophilic colloid layer in the photographic light-sensitive material is colored and that the dye is prevented from being diffused to the other layers during storage and it is quickly decolored during a development processing. 
     Further, the second object of the present invention is to provide a pentamethineoxonol dye which has an absorption in a near infrared region and is stable in a hydrophilic colloid layer and which can be readily and inexpensively synthesized. 
     The first object of the present invention can be achieved by a silver halide photographic light-sensitive material comprising a hydrophilic colloid layer containing at least one dye dispersed in the form of a solid fine particle represented by the following Formula (I): ##STR2## wherein R 1 , R 2 , R 3  and R 4  each represent a hydrogen atom, an aliphatic group, an aromatic group, or a heterocyclic group; X 1  and X 2  each represent an oxygen atom or a sulfur atom; L 1 , L 2  and L 3  each represent a methine group; n represents 0, 1 or 2; provided that R 1 , R 2 , R 3 , R 4 , L 1 , L 2 , and L 3  do not have a group having proton capable of being converted to an ion, or a salt thereof; and in case of n=2, at least one of L 1 , L 2  and L 3  contains a substituent. 
     In a preferred embodiment, the maximum absorption wavelength λmax of the dye represented by formula (I) in the hydrophilic colloid layer satisfies the following equation: 
     
         λmax&gt;[λmax(DMF)+20×(n+1)] nm 
    
     wherein λmax(DMF) represents a maximum absorption wavelength of the dye in dimethylformamide; and n is synonymous with n defined in Formula (I). 
     The second object can be achieved by an oxonol compound represented by the following Formula (V): ##STR3## wherein R represents an aryl group; X represents a chalcogen atom; Y represents an alkyl group; provided that R and Y each do not have a group having proton capable of being ionized or a salt thereof.

The details of the synthetic processes of these compounds can be referred, e.g., to &#34;New Experimental Chemistry Course&#34; (Vol. 14) (Maruzen) and J. Am. Chem. Soc. 78, pp. 6185 (1956). ##STR5## 
     In the present invention, there can arbitrarily be selected for dispersing the dye represented by Formula (I) or (V), a disperser and a vibrating ball mill such as a ball mill, a sand mill, and a colloid mill, and a disperser such as a planetary ball mill, a jet mill, a roll mill, Manton-Gaulin, a microfulidizer, and a disk impeller mill, as described in JP-A-52-92716 and WO 88/04794. A medium disperser of a vertical type or a horizontal type is preferred. 
     In any cases, a solvent (for example, water) is preferably used, and further a surface active agent for dispersion is more preferably used. There can be used as the surface active agent for dispersing, an anionic surface active agent as described in JP-A-52-92716 and WO 88/04794, and an anionic polymer as described in JP-A-4-324858. A nonionic surface active agent or a cationic surface active agent can be used as well depending on the purpose, but the anionic polymer or the anionic surface active agent is preferred. 
     Further, after the dye of the present invention is dissolved in a suitable solvent, a poor solvent for the dye of the present invention is added to allow fine crystals to be deposited. Also in this case, the above surface active agents for dispersing may be used as well. Alternatively, pH is controlled in a solvent to allow the dye to be first dissolved and then pH is changed to permit it to be finely crystallized. 
     The dye of the present invention in a dispersion has an average particle size of 0.005 to 10 μm, preferably 0.01 to 1 μm, and more preferably 0.01 to 0.5 μm. In some cases, it is preferably 0.01 to 0.1 μm. The fine particles of the dye are preferably monodispersed. 
     In dispersing the dye of the present invention, the solid dye may be dispersed as it is without subjecting it to any pre-treatment. In this case, the solid dye kept in a wet condition, which is obtained in a synthetic process of the dye, is preferably used for dispersing. 
     Further, a heat treatment may be carried out before and/or after dispersing if necessary, and the heat treatment is provided preferably at least after dispersing in order to effectively carry out the heat treatment. 
     A heating process is not specifically limited as long as a dye solid is heated. A temperature is preferably 40° C. or higher and the upper limit thereof may be any degree as long as it falls within a range in which the dye is not decomposed. It is preferably 250° C. or lower, more preferably 50° to 150° C. 
     A heating time is not specifically limited as long as it falls within a range in which the dye is not decomposed, and it is 15 minutes to 1 week, more preferably 1 hour to 4 days. 
     The heating treatment is carried out preferably in a solvent in order to effectively perform it. The kind of the solvent is not limited as long as it does not substantially dissolve the dye of the present invention, and there can be enumerated, for example, water, alcohols (for example, methanol, ethanol, isopropyl alcohol, butanol, isoamyl alcohol, octanol, ethylene glycol, diethylene glycol, and ethyl cellosolve), ketones (for example, acetone and methyl ethyl ketone), esters (for example, ethyl acetate and butyl acetate), alkylcarboxylic acids (for example, acetic acid and propionic acid), nitriles (for example, acetonitrile), and ethers (for example, dimethoxyethane, dioxane, and tetrahydrofuran). 
     The coexistence of organic carboxylic acids in the heating treatment can more effectively solve the subjects of the present invention. There can be enumerated as organic carboxylic acid, alkylcarboxylic acids (for example, acetic acid and propionic acid), carboxymethyl celluloses (CMC), and arylcarboxylic acids (for example, benzoic acid and salicylic acid). 
     The amount of organic carboxylic acids can be used by 0.5 to 100 times the weight of the dye of the present invention in the case where they are used as a solvent. In the case where a solvent other than organic carboxylic acids is used under the presence of organic carboxylic acid, it can be used in a weight ratio of 0.05 to 100% based on the dye of the present invention. 
     The dye of the present invention can be used in an effective arbitrary amount, and it is preferably used so that the optical density thereof falls within the range of 0.05 to 3.0. The addition amount thereof is preferably 0.5 to 1000 mg/m 2 , more preferably 1 to 500 mg/m 2 . The addition timing may be in any process before coating. 
     The dye of the present invention can be used for any of an emulsion layer and the other hydrophilic colloid layers (for example, an intermediate layer, a protective layer, an anti-halation layer, and a filter layer). It may be used either for a single layer or plural layers. 
     Gelatin is representative as a hydrophilic colloid, and in addition thereto, any conventionally known hydrophilic colloids for photographic use can be used. 
     Preferred as the silver halide emulsion used in the present invention are silver bromide, silver iodide, silver iodobromide, silver iodochlorobromide, silver chlorobromide, and silver chloride. 
     The silver halide grain used in the present invention is of a regular crystal form such as cube and octahedron, an irregular form such as sphere and a plate, or a composite form of these crystal forms. Further, the mixture of the grains having various crystal forms can be used but the grains having a regular crystal form are preferably used. 
     With respect to a silver halide grain, a photographic emulsion, a preparation process thereof, a binder or a protective colloid, a hardener, a sensitizing dye, a stabilizer, and an anti-foggant, the contents described at the 18th line of a left lower column at 18 page to the 17th line of a left lower column at page 20 of JP-A-3-238447 can be applied to the present invention as they are. 
     The light-sensitive material according to the present invention may contain one or more kinds of a surface active agent for various purposes such as a coating aid, an anti-electrification, an improvement in a sliding property, an emulsion dispersion, an anti-adhering, and an improvement in the photographic characteristics (for example, a development acceleration, a hardening of a gradation, and a sensitization). 
     The light-sensitive material prepared according to the present invention may contain a dye other than the dye of the present invention in a hydrophilic colloid layer as a filter dye or for the various purposes of an anti-irradiation, an anti-halation and others. There are preferably used as such the dye, an oxonol dye, a hemioxonol dye, a styryl dye, a merocyanine dye, an anthraquinone dye, and an azo dye, and in addition thereto, useful as well are a cyanine dye, an azomethine dye, a triarylmethane dye, and a phthalocyanine dye. In the case where these dyes are water soluble, they can be added dissolving in water, and in the case where they are difficult to dissolve in water, they can be added as a solid fine particle dispersion. It is possible as well to add an oil soluble dye to a hydrophilic colloid layer emulsifying by an oil-in-water dispersion process. 
     With respect to a multi-layer multi-color photographic material, a support, a process for coating a photographic emulsion layer, an exposing means for a light-sensitive material, and a photographic processing of a light-sensitive material, there can be applied the contents described at the 14th line of a right lower column at page 20 to the 2nd line of a right upper column at page 27 of JP-A-3-238447. 
     This invention will now be illustrated in more detail by reference to the following examples. However, the invention should not be construed as being limited to these examples. 
     EXAMPLE 1 
     Preparation of Tabular Grains 
     A silver nitrate aqueous solution (37 ml) (silver nitrate: 4.00 g) and an aqueous solution (38 ml) containing potassium bromide (5.9 g) were added to a vessel to which potassium bromide (6 g) and gelatin (7 g) were added in 1 liter of water and which is kept at 55° C. by a double jet process for 37 seconds while stirring. Next, gelatin (18.6 g) was added and then a silver nitrate aqueous solution (89 ml) (silver nitrate: 9.8 g) was added over a period of 22 minutes after the temperature was raised to 70° C. A 25% aqueous ammonia solution (7 ml) was added to provide a physical ripening for 10 minutes while keeping the temperature as it was, followed by adding a 100% acetic acid solution (6.5 ml). Subsequently, an aqueous solution of silver nitrate (153 g) and an aqueous solution of potassium bromide were added by a controlled double jet process over a period of 35 minutes while maintaining pAg at 8.5. Then, a 2N potassium thiocyanate aqueous solution (15 ml) was added. After providing a physical ripening for 5 minutes while keeping the temperature as it was, the temperature was lowered down to 35° C. Thus, there were obtained monodispersed pure silver bromide tabular grains having an average projected area-corresponding circle diameter of 1.10 μm, an average thickness of 0.165 μm, and a diameter fluctuation coefficient of 18.5%. 
     Thereafter, the soluble salts were removed by a sedimentation process. The temperature was raised once again to 40° C. and there were added gelatin (30 g), phenoxy ethanol (2.35 g), and poly(sodium styrenesulfonate) (0.8 g) as a thickener, followed by adjusting pH and pAg to 5.90 and 8.25, respectively, with caustic soda and a silver nitrate solution. 
     This emulsion was subjected to a chemical sensitization while stirring and keeping the temperature at 56° C. 
     First, thiourea dioxide (0.043 mg) was added and the emulsion was left for standing as it was for 22 minutes to subject it to a reduction sensitization. Then, 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene (20 mg) and a sensitizing dye (400 mg) of the following chemical structure were added: ##STR6## 
     Further, potassium chloride (0.83 g) was added. Subsequently, there were added sodium thiosulfate (1.3 mg), selenium compound-1 (2.7 mg) of the following chemical structure, chlorauric acid (2.6 mg), and potassium thiocyanate (90 mg), and the solution was cooled down to 35° C. 40 minutes later. 
     Thus, the silver halide tabular grains T-1 was prepared. ##STR7## Preparation of Coated Sample 
     The following compounds per mole of silver halide of T-1 were added to prepare the coating solutions for preparing the coated samples.

     Preparation of Support: 
     (1) Preparation of dye dispersion D-1 for a subbing layer. 
     The dye I-21 of the present invention was treateded with a ball mill by the process described below. 
     Water (434 ml) and a 6.7% aqueous solution (791 ml) of a surface active agent Triton X-200 (TX-200) were put in a 2 liter ball mill and the dye I-21 (20 g) was added to this solution. The beads (400 ml) (diameter: 2 mm) of zirconium oxide (ZrO) were put therein and the content was crashed for 4 days. Then, a 12.5% gelatin aqueous solution (160 g) was added and after defoaming, the ZrO beads were removed by filtering. The observation of the dye dispersion thus obtained showed that the particle sizes of the crashed dye were distributed in a wide range extending from 0.05 to 1.20 μm in diameter and that an average particle size was 0.39 μm. 
     Further, a centrifugal procedure was applied to remove the dye particles having the sizes of 0.9 μm or more. Thus, the dye dispersion D-1 was obtained.

     Evaluation of Photographic Performances 
     A GRENEX ortho screen HR-4 manufactured by Fuji Photo Film Co., Ltd. was tightly contacted to one side of a photographic material with an aid of a cassette and the photographic material was subjected to an X ray sensitometry. An exposure was adjusted by changing a distance between an X ray tube and the cassette. After exposure, the photographic material was subjected to a processing with an automatic developing machine in the following developing solution and fixing solution. A sensitivity was expressed by a value relative to that of the Photographic Material 1-9, which was set at 100. 
     Measurement of Sharpness (MTF): 
     The above cassette (the HR-4 screen was sticked on the both sides thereof) and the processing with the automatic developing machine were combined to measure MTF. The measurement was carried out at an aperture of 30 μm×500 μm and the sharpness was evaluated with an MTF value having a space frequency of 1.0 cycle/mm at a portion having an optical density of 1.0. 
     Measurement of Residual Color 
     An unexposed photographic film was subjected to the processing with the above automatic developing machine, and then a green color transmission density thereof was measured through a Macbeth status A filter. Meanwhile, a non-subbed blue-colored polyethylene terephthalate support was subjected to a measurement of a green color transmission density, and a net value obtained by deducting the latter value from the former one was evaluated as a residual color density. 
     The automatic developing machine used for this experiment was an automatic developing machine FPM-9000 type manufactured by Fuji Photo Film Co., Ltd., which was modified so as to equip an infrared dryer in a drying unit, and the processing steps therefor are as shown in the following Table 2. An average processing amount of a light-sensitive material is 200 sheets (sheet size: 25.4 cm×30.5 cm) per day.

     It can be found from the results summarized in Table 4 that the samples (Photographic Materials 2-1 to 2-5) to which the dyes of the present invention were added have less desensitization also in the stored samples as compared with the comparative samples (Photographic Materials 2-6 to 2-7 and 2-9) to which the publicly known dyes were added and that the dye of the present invention is an excellent dye. It can be found as well that while the comparative samples (Photographic Materials 2-6 and 2-8 to 2-9) to which the publicly known dyes were added have the bluish residual color, the samples to which the dyes of the present invention were added reside at a level of the residual color at which no practicable problem is involved and that the dyes of the present invention are excellent as well in terms of a decoloring performance. Further, all of the samples to which the dyes were added had an excellent sharpness as compared with the sample (Photographic Material 2-10) to which the dye was not added.

     The processed sample thus obtained was visually observed immediately after processing and after storing under a humid and hot condition of 50° C. and 80% RH to evaluate a degree of a residual color. 
     Rank 1: no residual color is observed. 
     Rank 2: residual color was observed but at a level which is practically no problem. 
     Rank 3; level which is practically a problem. 
     The results are shown in Table 5. 
     The samples of the present invention had no residual color and an excellent storing performance after processing. 
     (Evaluation of Sensor Detectability) 
     Each 10 sheets of the sample were inserted from a film inserting port to test if they were detected. This automatic developing machine has a pair of an infrared emitting element (refer to FIG. 1) and a light receiving element (refer to FIG. 2) at an inserting port and is of a mechanism in which the inserted sample fully shuts off an infrared ray to recognize insertion of the sample and a transporting roller is started thereby to transport a film to a developing bath. 
     A sensor detectability was evaluated with the number of the sheet detected of 10 sheets. The larger the number is, the more preferable. The results are shown in Table 5. While Comparative Sample I-6 was not detected at all, the samples of the present invention provided a high detectability.

     Next, an example in which the compound represented by Formula (V) was used as a dye for an optical filter will be described below. 
     EXAMPLE 5 
     (Preparation of Optical Filter) 
     Coating on a polyethylene terephthalate film was carried out in the following coated amounts. 
     
         ______________________________________Aqueous dispersion of I-1                   70    mg/m.sup.2                (as silid matter of I-1)Gelatin                 4.0   g/m.sup.2Sodium dodecylbenzenesulfonate                   40    mg/m.sup.2Poly(sodium styrenesulfonate)                   23    mg/m.sup.22-Bis(vinylsulfonylacetoamide)ethane                   42    mg/m.sup.2______________________________________ 
    
     The aqueous dispersion of I-1 was prepared by the process shown below. That is, there were previously stirred and mixed, I-1 (2.5 g), a 4.3% aqueous solution (10.3 g) of a surface active agent (trade name Triton X-200, manufactured by Rohm &amp; Haas Co., Ltd.), and water (50.5 g). The mixture was put in an Igar motor mill (M-50, manufactured by Igar Japan Co., Ltd.) containing zirconia beads (40 ml) having a diameter of 0.8 to 1.2 mm and was dispersed at 5000 r.p.m., whereby a fine crystal dispersion of a dye having a particle size of 1 μm or less was obtained. The fine crystal dispersion thus obtained of I-1 (50 g), gelatin (1.8 g) and water (13.3 g) were stirred and mixed at 40° C. to thereby prepare an aqueous dispersion of I-1. 
     It can be found that the film for an optical filter thus obtained is a film having a sharp absorption showing a high absorbance in a near infrared region (λmax 789 nm). 
     COMPARATIVE EXAMPLE 1 
     The procedure of Example 5 was repeated, except that I-1 used in Example 5 was replaced with the following comparative compounds described in JP-A-4-352151 and JP-A-63-27838, and the optical densities of the films were measured in the same manner as that in Example 5. The results are shown in Table 7. ##STR33##

     It can be found from the results shown in Table 7 that an absorption characteristic of the comparative compounds is broadened and an absorption in a near infrared region is almost nothing. 
     (Evaluation of Stability of Novel Compound) 
     After storing the respective films for 3 days under the conditions of 50° C. and 80% RH, they were subjected to a measurement of an absorbance at λmax and a ratio thereof to that before storing was calculated to obtain a scale for a stability. A value closer to 100 shows that an absorption wave form is not changed and the stability is high. The results are shown in Table 8. 
     
                       TABLE 8______________________________________Compound          Residual Rate (%)______________________________________I-1               100Comparative Compound-1             279Comparative Compound-2              80______________________________________ 
    
     It can be found from the results shown in Table 8 that while the comparative compounds show decomposition or dissolution action (the case of the comparative compound-1) after storing, the compound of the present invention does not have a change in an absorption wave form and pretty excels in a stability. 
     As described above, the present invention provides a photographic material which is low in the sensitivity decrease, excellent in the sharpness, and less in the residual color by using a dye dispersed in the form of a solid fine particle represented by Formula (I) in a hydrophilic colloid layer. 
     Further, a compound which can readily be synthesized and has a high stability and a sharp absorption having a large absorbance in a near infrared region can be provided by the oxonol compound represented by Formula (V). 
     While the invention has been described in detailed with reference to specific embodiments, it will be apparent to one skilled in the art that various changes and modifications can be made to the invention without departing from its spirit and scope.
