Description: SILVER HALIDE PHOTOGRAPHIC LIGHT-SENSITIVE MATERIAL The present invention relates to a silver halide photographic light-sensitive material containing a new non-diffusible dye, more specifically a silver halide photographic light-sensitive material containing a new non-diffusible dye exhibiting an improved efflux-decoloring property during processing. With respect to silver halide photographic light-sensitive materials (hereinafter referred to as light-sensitive materials), it is a well-known fact that a dye is added to a structural layer of the light-sensitive material to absorb light in a particular wavelength band for the purpose of light absorbing filtration, prevention of halation, prevention of irradiation or regulation of the sensitivity of light-sensitive emulsion; accordingly, it is conventional practice to color the hydrophilic colloid layer with such a dye. Of the structural layers of the light-sensitive material, the filter layer, usually located on a light-sensitive emulsion layer or between said emulsion layer and another emulsion layer, serves to change the incident light coming in the emulsion layer into light with the desired spectrum. The anti-halation layer, provided between a light-sensitive emulsion layer and the support or on the back face of the support for the purpose of improving image sharpness, serves to absorb harmful reflected light in the interface between the emulsion layer and the support or on the back face of the support to improve image sharpness. It is another practice to improve image sharpness by preventing irradiation by absorbing reflected light, scattered light and other light which are harmful to silver halide grains by the use of a dye to color a light-sensitive emulsion layer. The dyes used for these purposes must not only possess an absorption spectral characteristic suitable to the purpose of use thereof but also meet various requirements, such as complete decoloring during development, easy dissolution from the light-sensitive material during development, freedom of residual color stain by the dye after processing, absence of adverse effects, such as fogging and desensitization, on the light-sensitive emulsion, prevention of dye diffusion from the colored layer to another layer, and excellent storage stability with no discoloration or fading in the light-sensitive material or in aqueous solutions. To date, numerous investigations have been made to develop a dye meeting these requirements, including the benzylidene dyes proposed in US Patent Nos. 3,540,887, 3,544,325 and 3,560,214, Japanese Patent Examined Publication No. 10578/1956 and Japanese Patent Publication Open to Public Inspection (hereinafter referred to as Japanese Patent O.P.I. Publication) No. 3623/1976, the oxonol dyes proposed in British Patent No. 506,385 and Japanese Patent Examined Publication No. 22069/1964, the merocyanine dye proposed in US Patent No. 2,493,747 and the styryl dye proposed in US Patent No. 1,845,404. Although some of these conventional dyes relatively little affect emulsion performance and are bleacheable, soluble, discolorable or otherwise changeable during processing, they are unsatisfactory as to diffusion resistance. Specifically, they have a drawback that when a particular one of the plurality of layers is selectively colored to use as a filter layer or an anti-halation layer, they not only diffuse considerably into other layers and degrade the light absorption effect but also exhibit undesirable spectral action on other layers. Thus, as a means of selectively dyeing a particular hydrophilic colloid layer, there has been proposed the use of a mordant to immobilize the dye and the use of a non-diffusible dye. However, the method using a mordant is unsatisfactory because coatability is poor, interlayer diffusion cannot be suppressed satisfactorily, and, in addition, efflux-decoloring properties during processing are poor, a high pH processing bath is required, and suitability to rapid processing is poor. There have been made a large number of investigations on the use of a non-diffusible dye, including the silver salts of oxonol dye having a thiobarbituric acid parent nucleus with a particular structure described in British Patent No. 1,077,049 and US Patent No. 3,471,293. GB-A- 524500 also discloses salts of barbituric acid derivatives for this purpose. Although these known silver salts of dye possess sufficient diffusion resistance to suppress interlayer diffusion, they have a drawback of efflux-decoloring property during processing. Thus, there is no dye meeting these requirements; there is strong demand for the development of such a dye. It is an object of the present invention to provide a silver halide photographic light-sensitive material wherein the light-sensitive silver halide emulsion layer or a non-light-sensitive colloid layer contains a non-diffusible dye possessing good absorption spectral characteristics, which is excellent in efflux-decoloring properties during photographic processing and highly suitable for rapid photographic processing, and which has no adverse effects, such as fogging and desensitization, on the photographic properties of the light-sensitive silver halide emulsion.

Examples of silver halide emulsions for the light-sensitive material of the present invention include those in common use for silver halide emulsions, such as silver chloride, silver bromide, silver iodide, silver chlorobromide, silver iodobromide and silver chloroiodobromide. The silver halide emulsion used in the light-sensitive material of the present invention can be prepared by various methods, including the method described in Japanese Patent Examined Publication No. 7772/1971 and the method described in US Patent No. 2,592,250, wherein a so-called conversion emulsion is prepared by first forming an emulsion of silver salt grains whose solubility product is higher than that of silver bromide, and then converting at least a part of these particles to silver bromide salt or silver iodobromide salt. This silver halide emulsion can be sensitized with a chemical sensitizer, e.g., a sulfur sensitizer such as thiosulfate, allyl thiocarbamide, thiourea, allyl isothiocyanate or cystine, an active or inert selenium sensitizer, or a noble metal sensitizer such as potassium chloroaurate, auric trichloride, potassium auric thiocyanate or 2-aurothiabenzothiazolemethyl chloride or other gold sensitiser, ammonium chloropalladate, sodium chloropalladate or another palladium sensitiser, potassium chloroplatinate or another platinum sensitiser or a ruthenium sensitiser, or a combination thereof. This emulsion can also be subjected to reduction sensitization using a non-chemical sensitizer, and can be stabilized with for example, a triazole, an imidazole, an azaindene, a benzothiazolium compound, a zinc compound, a cadmium compound, a mercaptan or a mixture thereof, and can contain a sensitizing compound of the thioether type, quaternary ammonium type or polyalkylene oxide type, for example.

In the light-sensitive material of the present invention, the silver halide emulsion may contain a color coupler. The coupler may be 4-equivalent or 2-equivalent and may be a colored coupler for masking or a coupler which releases a developing inhibitor. The couplers which are advantageously used are chain-opened ketomethylene compounds such as acylacetamide for yellow dyes, pyrazolone compounds, pyrazolotriazole compounds and pyrazolotetrazole compounds for magenta dyes and phenol compounds and naphthol compounds for cyan dyes. The light-sensitive material of the present invention can take any layer structure which ordinary light-sensitive materials can take.

Example 1 0.1 mol of each of the dyes listed in Tables 1 and 2 and 10.1 g (0.1 mol) of triethylamine were dissolved in 1000 ml of water, and 200 ml of a 1 mol/l aqueous solution of silver nitrate was added drop by drop with stirring. The resulting precipitate was collected by filtration, washed and dried to yield the desired silver salt of dye. To 700 ml of a 3% aqueous solution of gelatin, 0.05 mol of the silver salt of dye described above and 30 ml of a 6.7% solution of surfactant Triton X-200 (produced by Rohm & Haas Co.) were added, and 2 kg of glass beads (1 mm diameter) were added, followed by pulverization for 8 hours using a medium agitation mill (Aquamizer QA-5, produced by Hosokawa Micron), to yield a dispersion of the silver salt of dye. To 100 ml of each dispersion thus obtained, 0.1 g of bisvinylsulfonylmethyl ether H-1 as a gelatin hardener and a coating aid Su-1 were added, after which the dispersion was coated and dried on a cellulose triacetate film support, subbed with a gelatin layer, to a coating amount of each silver salt of dye of 0.001 mol/m 2 , to yield sample Nos. 1-1 through 1-27. Using the method described in Example 1 of Japanese Patent O.P.I. Publication No. 23441/1991, a fine dispersion of dye D-2 was prepared, and hardener H-1 and coating aid Su-1 were added in the same manner as with sample Nos. 1-1 through 1-27, and the resulting mixture was coated and dried on a cellulose triacetate film support, subbed with a gelatin layer, to a coating amount of dye of 0.001 mol/m 2 , to yield sample No. 1-28. In accordance with the method described in Examples 1 through 9 of Japanese Patent O.P.I. Publication No. 291051/1988, an aqueous solution of gelatin containing dye D-3 and a polymer dispersion mordant in a ratio by volume of 1 part of the former to about 40 parts of the latter was coated and dried on a cellulose triacetate film support, subbed with a gelatin layer, to a coating amount of dye of 0.001 mol/m 2 , to yield sample No. 1-29. Sample Nos. I-1 to I-10, I-12, I-13 and I-16 through 1-29 thus obtained were each processed with the following fixer A, alkali solution B and water at 20°C for 15 seconds, washed and dried, after which they were subjected to spectrometry using a spectrophotometer, and the decoloring ratio at the maximum absorption wavelength, relative to the non-processed sample, was calculated using the following equation.

Publication No. 139949/1988. Su-1 Polymer dispersion mordant From Tables 1 and 2, it is evident that the silver salt of dye as defined in the present invention has a greater bleaching rate with less color residence after fixation in comparison with the silver salts of comparative dyes D-1 through D-4. The dye used in the present invention is also characterized by a higher bleaching effect by fixer processing in comparison with known comparative dyes D-5 and D-6. The silver salt of dye used in the present invention was also found to possess good diffusion resistance comparable to that of the silver salts of comparative dyes and comparative non-diffusible dyes. Example 2 Preparation of sample No. 2-1 A 10% aqueous solution of gelatin was coated on a cellulose triacetate film support, previously coated with a gelatin layer, to yield a first layer. Simultaneously, a light-sensitive silver halide emulsion layer and a surface protecting layer, which had the following compositions, were double coated on layer 1 to yield sample No. 2-1. Composition of light-sensitive silver halide emulsion layer Composition of surface protecting layer Preparation of sample Nos. 2-2 through 2-23 Multiple-layered photographic material sample Nos. 2-2 to 2-14, 2-16, 2-17 and 2-19 through 2-23 were prepared in the same manner as with sample No. 2-1 except that the 10% aqueous solution of gelatin for layer 1 was replaced with a dispersion prepared using each of the silver salts of dyes or the comparative dyes shown in Table 3 as directed in Example 1. Sample Nos. 2-1 through 2-23 thus obtained were each subjected to white light exposure through an optical wedge and then processed in the following procedures to assess effects on photographic performance. Processing procedure (20°C) Development 2 minutes Fixation 3 minutes Washing 3 minutes Drying The processing solutions used in the respective procedures had the following compositions: Developer Water was added to make a total quantity of 1 l. Fixer Water 600 ml Ammonium thiosulfate 80 g Anhydrous sodium sulfite 5 g Sodium bisulfite 5 g Water was added to make a total quantity of 1 l, and acetic acid was added to obtain a pH of 6.0. The results are shown in Table 3. As shown in Table 3, comparative dyes D-1 through D-3 had slightly increased fogging density, indicating an effect on fogging. Although comparative dyes D-4 and D-5 did not affect fogging, yellowing occurred in D-4, and coatability was adversely affected in D-5. On the other hand, the silver salt of dye used in the present invention did not affect coatability, having little effect on the silver halide in adjoining layers. The dye used in the present invention was also found to have a good property of improved sharpness in comparison with sample No. 2-1.
