Description

Ionic compounds, compositions, functional materials, silver halide photographic materials, and diffusion transfer type silver halide photographic materials

[0001] The present disclosure relates to an ionic compound, a composition, a functional material, a silver halide photographic material, and a diffusion transfer type silver halide photographic material.

[0002] In recent years, significant improvements in sensitivity have been achieved in silver halide photographic materials to enhance user benefits. Furthermore, as the manufacturing, exposure, and processing processes of silver halide photographic materials become faster and more automated, they must be able to withstand contact with various rollers and other equipment, as well as friction between other materials. Photosensitive materials generally consist of an electrically insulating support and a photographic emulsion layer. Therefore, electrostatic charge is prone to buildup during the manufacturing process and use of the material due to contact with the surface of the same or different materials, friction caused by peeling, etc. If electrostatic charge builds up before development, the photosensitive layer is exposed to light due to the discharge of this charge, resulting in static fog after development. Furthermore, accumulated electrostatic charge can also lead to problems such as dust adhesion to the photosensitive material.

[0003] As conventional silicon compounds, for example, the silicon compounds described in Non-Patent Document 1, Non-Patent Document 2, or Patent Document 1 are known.

[0097] (Silver Halide Photosensitive Material) The silver halide photosensitive material according to the present disclosure has a support and a layer containing an ionic compound having an anionic structure represented by the following formula 1 (ionic compound according to the present disclosure).

[0098]

[0099] In Formula 1, w represents an integer of 1 or more, x represents an integer of 2 or more, and Sil １ represents a substituent containing at least three Si atoms, and a plurality of Si １ may be the same or different, L １ represents a divalent linking group, and a plurality of L １ may be the same or different, and R represents an (x+w)-valent organic group containing a carbon atom.

[0100] The silver halide photographic light-sensitive material is preferably a material that is sensitive to light, laser or X-ray irradiation, and is suitably selected from, for example, black-and-white reversal film, black-and-white negative film, color reversal film, color negative film, film in which a light-sensitive photographic element has been digitally scanned, black-and-white reversal paper, black-and-white paper, color paper, reversal color paper, paper in which a light-sensitive photographic element has been exposed by laser irradiation from a digital database, and heat-developed light-sensitive material.

[0101] Preferred embodiments of the ionic compound in the silver halide photographic light-sensitive material according to the present disclosure are the same as those of the ionic compound according to the present disclosure described above. The silver halide photographic light-sensitive material according to the present disclosure may contain one ionic compound according to the present disclosure alone, or two or more ionic compounds according to the present disclosure. The content of the ionic compound according to the present disclosure in the layer of the silver halide photographic light-sensitive material according to the present disclosure may be appropriately selected depending on the application, but is preferably 0.0001% by mass to 50% by mass, more preferably 0.001% by mass to 20% by mass, and particularly preferably 0.01% by mass to 10% by mass, relative to the total mass of the layer.

[0102] The layer may be any layer constituting the silver halide photographic light-sensitive material described below. When a layer is formed by coating, it is preferably the outermost layer during coating. When multiple layers are sequentially laminated, it is preferably used as the outermost layer in each sequential coating. Furthermore, in the silver halide photographic light-sensitive material according to the present disclosure, the layer containing the ionic compound according to the present disclosure may be one layer or two or more layers. The layer may contain various components contained in the silver halide photographic light-sensitive material described below.

[0103] In the present disclosure, when the ionic compound according to the present disclosure is used in a layer of a photographic photosensitive material, the aqueous coating composition containing the ionic compound according to the present disclosure may consist only of the ionic compound according to the present disclosure and water, or may contain other components as appropriate depending on the purpose.

[0104] In the above aqueous coating composition, the ionic compound according to the present disclosure may be used alone or in a mixture of two or more. Furthermore, a surfactant other than the ionic compound according to the present disclosure may be used together with the ionic compound according to the present disclosure. Usable surfactants include various anionic, cationic, and nonionic surfactants, and may be polymeric surfactants or silicone surfactants other than the ionic compound according to the present disclosure. Among these, anionic or nonionic surfactants are more preferred. Specific examples include compounds that can be used in the functional materials according to the present disclosure. Furthermore, when targeting photosensitive materials, nonionic surfactants having an alkylene oxide group, particularly among silicone surfactants, are preferred because they cause less sensitivity loss during storage of the photosensitive material and, particularly when used with diffusion transfer silver halide photographic photosensitive materials, cause less mordanting inhibition. Examples of surfactants that can be used in combination include those described in JP-A-62-215272 (pp. 649-706), Research Disclosure (RD) Item 17643, pp. 26-27 (December 1978), RD Item 18716, p. 650 (November 1979), and RD 307105, p. 875-876 (November 1989).

[0105] A typical example of a material that may be contained in the aqueous coating composition is a polymer compound. The polymer compound may be a polymer soluble in a water-soluble solvent (a soluble polymer) or an aqueous dispersion of a polymer (a so-called polymer latex). Soluble polymers are not particularly limited, and examples thereof include gelatin, polyvinyl alcohol, casein, agar, gum arabic, hydroxyethyl cellulose, methyl cellulose, and carboxymethyl cellulose. Examples of polymer latexes include homo- or copolymers of various vinyl monomers (e.g., acrylate derivatives, methacrylate derivatives, acrylamide derivatives, methacrylamide derivatives, styrene derivatives, conjugated diene derivatives, N-vinyl compounds, O-vinyl compounds, vinyl nitriles, and other vinyl compounds (e.g., ethylene, vinylidene chloride)), and dispersions of condensation polymers (e.g., polyesters, polyurethanes, polycarbonates, and polyamides). Detailed examples of this type of polymer compound can be found, for example, in JP-A-62-215272 (pp. 707-763), Research Disclosure (RD) Item 17643, p. 651 (December 1978), RD Item 18716, p. 650 (November 1979), and RD Item 307105, p. 873-874 (November 1989).

[0106] The solvent in the aqueous coating composition may be water alone or a mixed solvent of water and an organic solvent other than water (e.g., methanol, ethanol, isopropyl alcohol, n-butanol, methyl cellosolve, dimethylformamide, acetone, ethyl acetate, etc.). The proportion of water in the solvent in the aqueous coating composition is preferably 50% by mass or more.

[0107] The aqueous coating composition may contain various compounds depending on the layer of the photographic material to be used, and these may be dissolved or dispersed in the medium. Examples of these compounds include various couplers, ultraviolet absorbers, color mixing inhibitors, static inhibitors, scavengers, antifoggants, hardeners, dyes, and antifungal agents. In order to obtain effective antistatic properties and coating uniformity when used in a photographic material, it is preferable to use the composition in the uppermost hydrophilic colloid layer.

[0108] In this case, the coating composition of the layer may contain, in addition to the hydrophilic colloid (e.g., gelatin) and the ionic compound according to the present disclosure, other surfactants, matting agents, slipping agents, colloidal silica, plasticizers, etc.

[0109] There are no particular limitations on the amount of the ionic compound according to the present disclosure used, and the amount can be arbitrarily changed depending on the structure and use of the ionic compound according to the present disclosure, the type and amount of compounds contained in the aqueous composition, the composition of the solvent, etc. For example, when the ionic compound according to the present disclosure is used as a coating solution for the hydrophilic colloid (gelatin) layer that is the uppermost layer of a photographic light-sensitive material, which is a preferred embodiment of the present disclosure, the concentration in the coating solution is preferably 0.003% by mass to 0.5% by mass, and preferably 0.03% by mass to 10% by mass relative to the gelatin solid content.

[0110] In the present disclosure, when a photographic material has a layer made of a hydrophobic binder component, the composition for producing the layer can contain an ionic compound according to the present disclosure and a hydrophobic binder component together with an organic solvent. In this case, preferred embodiments are the same as those of the layer containing the ionic compound according to the present disclosure described above.

[0111] The silver halide photographic material according to the present disclosure may have at least one photosensitive layer provided on a support. A typical example is a silver halide photographic material having at least one photosensitive layer formed on a support and composed of multiple silver halide emulsion layers having substantially the same color sensitivity but different photosensitivities. The photosensitive layer is a unit photosensitive layer sensitive to blue, green, or red light. In a multilayer silver halide color photographic material, the unit photosensitive layers are generally arranged in the following order from the support side: red-sensitive layer, green-sensitive layer, and blue-sensitive layer. However, depending on the purpose, the above arrangement order may be reversed, or a different photosensitive layer may be sandwiched between layers of the same color sensitivity. Non-photosensitive layers may be provided between the above silver halide photosensitive layers, as well as in the top and bottom layers. These may contain couplers, DIR compounds, color-mixing inhibitors, etc., as described below. The plurality of silver halide emulsion layers constituting each unit photosensitive layer are preferably arranged in two layers, a high-sensitivity emulsion layer and a low-sensitivity emulsion layer, in order of decreasing sensitivity toward the support, as described in DE 1,121,470 or GB 923,045. Alternatively, a low-sensitivity emulsion layer may be arranged farther from the support and a high-sensitivity emulsion layer closer to the support, as described in JP-A Nos. 57-112751, 62-200350, 62-206541 and 62-206543.

[0112] Specific examples of the layers may be arranged in the order of low-sensitivity blue-sensitive layer (BL) / high-sensitivity blue-sensitive layer (BH) / high-sensitivity green-sensitive layer (GH) / low-sensitivity green-sensitive layer (GL) / high-sensitivity red-sensitive layer (RH) / low-sensitivity red-sensitive layer (RL), or in the order of BH / BL / GL / GH / RH / RL, or BH / BL / GH / GL / RL / RH, etc., from the side farthest from the support.

[0113] Furthermore, as described in JP-B No. 55-34932, the layers may be arranged in the order of blue-sensitive layer / GH / RH / GL / RL from the side farthest from the support. Furthermore, as described in JP-A Nos. 56-25738 and 62-63936, the layers may be arranged in the order of blue-sensitive layer / GL / RL / GH / RH from the side farthest from the support. Furthermore, as described in JP-B No. 49-15495, an example of an arrangement is one in which the upper layer is a silver halide emulsion layer with the highest photosensitivity, the middle layer is a silver halide emulsion layer with a lower photosensitivity, and the lower layer is a silver halide emulsion layer with an even lower photosensitivity than the middle layer, with the photosensitivity decreasing sequentially toward the support. Even when the film is composed of three layers having different photosensitivities, the layers sensitive to the same color may be arranged in the order of a medium-sensitivity emulsion layer, a high-sensitivity emulsion layer, and a low-sensitivity emulsion layer from the side farthest from the support, as described in JP-A-59-202464.

[0114] Alternatively, the layers may be arranged in the order of high-sensitivity emulsion layer / low-sensitivity emulsion layer / mid-sensitivity emulsion layer, or low-sensitivity emulsion layer / mid-sensitivity emulsion layer / high-sensitivity emulsion layer. Furthermore, even when there are four or more layers, the arrangement may be changed as described above. To improve color reproducibility, it is preferred to arrange a donor layer (CL) with a bilayer effect that has a different spectral sensitivity distribution from the main photosensitive layers such as BL, GL, and RL adjacent to or close to the main photosensitive layers, as described in U.S. Pat. Nos. 4,663,271, 4,705,744, and 4,707,436, and JP-A Nos. 62-160448 and 63-89850.

[0115] The preferred silver halide for use in the present disclosure is silver iodobromide, silver iodochloride, or silver iodochlorobromide containing about 30 mol % or less of silver iodide, and particularly preferred is silver iodobromide or silver iodochlorobromide containing about 2 mol % to about 10 mol % of silver iodide.

[0116] The silver halide grains in the photographic emulsion may be of a regular crystal shape such as a cube, octahedron, or tetradecahedron, an irregular crystal shape such as a sphere or plate, or a crystal with crystal defects such as twin planes, or a combination of these. The grain size of the silver halide may be about 0.2 μm or less, or may be large grains with a projected area diameter of up to about 10 μm, and the emulsion may be either polydispersed or monodispersed.

[0117] Silver halide photographic emulsions that can be used in the present disclosure are described, for example, in Research Disclosure (hereinafter abbreviated as RD) No. 17643 (December 1978), pp. 22-23, "I. Emulsion preparation and types," and in Research Disclosure No. 18716 (November 1979), p. 648, ... 307105 (November 1989), pp. 863-865, P. Glafkides, "Physics and Chemistry of Photography", Paul Montel (1967), G.F. Duffin, "Photographic Emulsion Chemistry", Focal Press (1966), V.L. Zelikman, et al., "Making and Coating Photographic Emulsions", Focal Press (1967), The preparation can be carried out by the method described in, for example, "Emulsion, Focal Press, 1964."

[0118] Monodisperse emulsions described in U.S. Pat. Nos. 3,574,628, 3,655,394, and GB 1,413,748 are also preferred. Tabular grains having an aspect ratio of about 3 or more can also be used in the present disclosure. In particular, to improve storage stability, it is preferable to use an emulsion in which 50% or more of the total projected area is occupied by silver halide tabular grains having an aspect ratio of 8 or more. There is no particular upper limit to the aspect ratio, but it is preferably 30 or less. Tabular grains can be readily prepared by the methods described in Gutoff, Photographic Science and Engineering, Vol. 14, pp. 248-257 (1970); U.S. Pat. Nos. 4,434,226, 4,414,310, 4,433,048, 4,439,520, and GB 2,112,157.

[0119] The crystal structure may be uniform, or may have different halogen compositions in the interior and exterior, or may have a layered structure. Silver halides of different compositions may be epitaxially bonded together, for example, with compounds other than silver halide, such as silver rhodanide or lead oxide. Also, a mixture of grains with various crystal forms may be used.

[0120] The above emulsion may be a surface latent image type in which the latent image is formed mainly on the surface, an internal latent image type in which the latent image is formed inside the grain, or a type in which the latent image is formed both on the surface and inside, but it must be a negative emulsion. Among internal latent image types, the core / shell internal latent image type emulsion described in JP-A No. 63-264740 may also be used, and its preparation method is described in JP-A No. 59-133542. The shell thickness of this emulsion varies depending on the development treatment, etc., but is preferably 3 nm to 40 nm, and particularly preferably 5 nm to 20 nm.

[0121] The silver halide emulsion is usually subjected to physical ripening, chemical ripening and spectral sensitization before use. Additives used in these processes are described in RD Nos. 17643, 18716 and 307105, and the relevant sections are summarized in the table below.

[0122] In the silver halide photographic material according to the present disclosure, two or more types of emulsions differing in at least one of the properties of the photosensitive silver halide emulsion, such as grain size, grain size distribution, halogen composition, grain shape, and sensitivity, can be mixed and used in the same layer. Surface-fogged silver halide grains described in U.S. Pat. No. 4,082,553, internally fogged silver halide grains described in U.S. Pat. No. 4,626,498 and JP-A-59-214852, and colloidal silver are preferably applied to a photosensitive silver halide emulsion layer and / or a substantially non-photosensitive hydrophilic colloid layer. Internally or surface-fogged silver halide grains refer to silver halide grains that can be developed uniformly (non-imagewise) regardless of whether they are exposed or unexposed areas of the photosensitive material, and their preparation methods are described in U.S. Pat. No. 4,626,498 and JP-A-59-214852. The silver halide forming the inner core of the core / shell type silver halide grains whose grains are internally fogged may have a different halogen composition. The silver halide used for interior or surface fogging may be any of silver chloride, silver chlorobromide, silver iodobromide, and silver chloroiodobromide. The average grain size of these fogged silver halide grains is preferably 0.01 μm to 0.75 μm, and more preferably 0.05 μm to 0.6 μm. The grain shape may be regular or may be a polydisperse emulsion, but monodisperse (at least 95% of the silver halide grains by mass or number have a grain diameter within ±40% of the average grain diameter) is preferred.

[0123] In the present disclosure, it is preferable to use non-photosensitive particulate silver halide. Non-photosensitive particulate silver halide refers to silver halide grains that are not exposed to light during imagewise exposure to obtain a dye image and are not substantially developed during the subsequent development process, and it is preferable that they are not pre-fogged. The particulate silver halide has a silver bromide content of 0 to 100 mol % and may contain silver chloride and / or silver iodide as necessary. Preferably, the particulate silver halide contains 0.5 to 10 mol % silver iodide. The average grain size (average value of the circle-equivalent diameter of the projected area) of the particulate silver halide is preferably 0.01 μm to 0.5 μm, more preferably 0.02 μm to 0.2 μm.

[0124] The particulate silver halide can be prepared in the same manner as ordinary photosensitive silver halide. The surface of the silver halide grains does not need to be optically sensitized, nor does it need to be spectrally sensitized. However, prior to adding it to the coating solution, it is preferable to add a known stabilizer such as a triazole-based, azaindene-based, benzothiazolium-based, or mercapto-based compound, or a zinc compound. Colloidal silver can be incorporated into this particulate silver halide grain-containing layer.

[0125] The coated silver amount of the silver halide photographic light-sensitive material according to the present disclosure is 6.0 g / m ２ Preferably, 4.5 g / m or less ２ The following is more preferred:

[0138] The silver halide photographic light-sensitive material according to the present disclosure preferably has a hydrophilic colloid layer (referred to as a backing layer) on the side opposite to the emulsion layer, the total dry film thickness of which is 2 μm to 20 μm. This backing layer preferably contains the above-mentioned light absorbers, filter dyes, ultraviolet absorbers, antistatic agents, film hardeners, binders, plasticizers, lubricants, coating aids, and surfactants.

[0141] The silver halide photographic light-sensitive material according to the present disclosure preferably has slipperiness. A slip-agent-containing layer is preferably used on both the light-sensitive layer surface and the back surface. The preferred slipperiness is a dynamic friction coefficient of 0.01 to 0.25. The measurement is the value when conveyed at 60 cm / min against a 5 mm diameter stainless steel ball (25°C, 60% RH). Even if the light-sensitive layer surface is substituted as the counter material in this evaluation, the value is approximately the same.

[0142] Examples of usable lubricants in the present disclosure include polyorganosiloxanes, higher fatty acid amides, higher fatty acid metal salts, and esters of higher fatty acids and higher alcohols. Examples of polyorganosiloxanes that can be used include polydimethylsiloxanes, polydiethylsiloxanes, polystyrylmethylsiloxanes, and polymethylphenylsiloxanes.

[0143] The silver halide photographic light-sensitive material according to the present disclosure preferably contains a matting agent. The matting agent may be added to either the emulsion side or the back side, but it is particularly preferred to add it to the outermost layer on the emulsion side. The matting agent may be either soluble or insoluble in the processing solution, and it is preferable to use both in combination. Examples of suitable matting agents include polymethyl methacrylate, poly(methyl methacrylate / methacrylic acid = 9 / 1 or 5 / 5 (molar ratio)), and polystyrene particles.

Furthermore, even if the silver halide photographic light-sensitive material according to the present disclosure is not sensitive to X-ray radiation, the constitution and components of a silver halide photographic light-sensitive material that is sensitive to X-ray radiation described below may be used, if necessary.

[0145] Further, silver halide photographic materials that are sensitive to X-ray irradiation will be explained below.

[0146] Preferred examples of the silver halide photographic light-sensitive material include silver halide photographic light-sensitive materials that are sensitive to X-ray irradiation.

[0147] [Silver Halide Emulsion] First, the silver halide emulsion used in the present disclosure will be described.

[0148] 1) Halogen Composition. Photosensitive silver halide grains can be silver chloride, silver chlorobromide, silver bromide, silver iodobromide, or silver iodochlorobromide. However, as mentioned above, from the viewpoint of rapid processing, the average iodine content of the photosensitive silver halide grains is preferably 0 mol % to 0.45 mol %. This iodine content is more preferably 0.05 mol % to 0.40 mol %, and even more preferably 0.10 mol % to 0.30 mol %. Here, the "average" iodine content of the photosensitive silver halide grains refers to the average iodine content calculated from the halogen composition of each photosensitive silver halide grain. The halogen composition distribution within the photosensitive silver halide grains may be uniform, stepwise, or continuously varying. Furthermore, photosensitive silver halide grains having a core / shell structure may also be used.

[0149] 2) Grain Shape Suitable photosensitive silver halide grains include so-called halogen conversion type grains, as described in British Patent No. 635,841 and U.S. Patent No. 3,622,318. Halogen conversion is usually achieved by adding an aqueous halide solution having a smaller solubility product with silver than the halogen composition on the grain surface before halogen conversion. For example, conversion is achieved by adding an aqueous potassium bromide and / or potassium iodide solution to silver chloride or silver chlorobromide tabular grains, or by adding an aqueous potassium iodide solution to silver bromide or silver iodobromide tabular grains. The concentration of these aqueous solutions added is preferably low, preferably 30% or less, and more preferably 10% or less. Furthermore, it is preferred to add the conversion halide solution at a rate of 1 mol% per minute or less per mole of silver halide before halogen conversion. Furthermore, during halogen conversion, a sensitizing dye and / or a silver halide adsorbent may be present in part or in whole, and silver halide grains such as silver bromide, silver iodobromide, or silver iodide may be added instead of the converted halogen aqueous solution. The size of these fine grains is preferably 0.2 μm or less, more preferably 0.1 μm or less, and particularly preferably 0.05 μm or less. The halogen conversion method is not limited to the above-mentioned methods, and can be used in combination as appropriate depending on the purpose.

[0150] 3) Grain Size Methods for forming photosensitive silver halide grains are well known in the art, and they can be prepared by using, for example, the methods described in JP-A No. 2-68539, U.S. Pat. No. 3,700,458, and Research Disclosure No. 17029, June 1978.

[0151] 4) Chemical Sensitization Methods Examples of chemical sensitization methods that can be used include those described in JP-A No. 2-68539, page 10, upper right column, line 13 to lower left column, line 16, JP-A Nos. 5-313282 and 6-110144. Specific examples of methods for chemically sensitizing silver halide emulsions include known methods such as sulfur sensitization, selenium sensitization, reduction sensitization, and gold sensitization in the presence of a silver halide adsorbent, and these methods can be used alone or in combination.

[0152] Among the noble metal sensitization methods, gold sensitization is a typical example, using gold compounds, primarily gold complex salts. Complex salts of noble metals other than gold, such as platinum, palladium, and iridium, may also be used. Specific examples are described in U.S. Pat. No. 2,448,060 and British Patent No. 618,061. Sulfur sensitizers that can be used include sulfur compounds contained in gelatin, as well as various sulfur compounds, such as thiosulfates, thioureas, thiazoles, and rhodanines. Specific examples are described in U.S. Pat. Nos. 1,574,944, 2,278,947, 2,410,689, 2,728,668, 5,501,313, and 3,656,955. Selenium sensitizers are described in JP-A-6-110144. The combined use of sulfur sensitization with thiosulfate, selenium sensitization, and gold sensitization is useful. As reduction sensitizers, stannous salts, amines, formamine disulfide acid, silane compounds, etc. can be used.

[0153] 5) Antifoggants and stabilizers Examples of antifoggants and stabilizers that can be used include those described in JP-A No. 2-68539, page 10, lower left column, line 17 to page 11, upper left column, line 7, and page 3, lower left column, line 2 to page 4, lower left column.

[0154] Specifically, compounds known as antifogging agents or stabilizers, such as azoles (for example, benzothiazolium salts, etroimidazoles, nitrobenzimidazoles, chlorobenzimidazoles, chromobenzimidazoles, nitroindazoles, benzotriazoles, and aminotriazoles); mercapto compounds (for example, mercaptothiazoles, mercaptobenzithiazoles, mercaptobenzimidazoles, mercaptothiadiazoles, mercaptotetrazoles, mercaptopyrimidazoles, and mercaptotriazines); thioketo compounds such as oxadrinethione; azaindenes (for example, triazaindenes, tetraazaindenes (particularly 4-hydroxy-substituted (1,3,3a,7)tetraazaindenes), pentaazaindenes); and benzenethiosulfonic acid, benzenesulfinic acid, and benzenesulfonic acid amide, may be added.

[0155] In particular, nitrones and derivatives thereof described in JP-A-60-76743 and JP-A-60-87322, mercapto compounds described in JP-A-60-80839, heterocyclic compounds described in JP-A-57-164735, and complex salts of heterocyclic compounds and acids (for example, 1-phenyl-5-mercaptotetrazoles) can be preferably used.

[0156] Furthermore, purines or nucleic acids, or polymeric compounds described in JP-B No. 61-36213 and JP-A No. 59-90844 can also be used. Among these, azaindenes, purines, and nucleic acids are particularly preferred. The amount of these compounds added is preferably 0.5 to 5.0 mmol, more preferably 0.5 to 3.0 mmol, per mol of silver halide.

[0157] 6) Color Tone Improvers Examples of color tone improvers include those described in JP-A No. 62-276539, page 2, lower left column, line 7 to page 10, lower left column, line 20, and JP-A No. 3-94249, page 6, lower left column, line 15 to page 11, upper right column, line 19. Specifically, the covering power of the silver halide photographic emulsion layer is set to 60 or more, and the silver halide photographic emulsion layer and / or other layers can contain a dye having a maximum absorption wavelength between 520 nm and 560 nm and a dye having a maximum absorption wavelength between 570 nm and 700 nm, so that the increase in optical density due to the contained dyes in the transmission density of the unexposed area after development processing is 0.03 or less.

[0158] Typical examples of emulsions that provide a covering power of 60 or more for a silver halide photographic emulsion layer include tabular emulsions and grain emulsions. In particular, when the silver halide photographic emulsion is composed of tabular silver halide grains with a grain thickness of 0.4 μm or less, or when a mixed emulsion of a high iodine surface photosensitive emulsion and an emulsion composed of grains with internal fogging is used, the effect of improving color tone is significant. Dyes that can be used to improve color tone include a combination of a dye having a maximum absorption wavelength preferably between 520 nm and 560 nm, more preferably between 530 nm and 555 nm, and a dye having a maximum absorption wavelength preferably between 570 nm and 700 nm, more preferably between 580 nm and 650 nm. The maximum absorption wavelength refers to the maximum absorption wavelength when the dye is present in the photosensitive material.

[0159] Dyes having a predetermined maximum wavelength are selected from, for example, anthraquinone dyes, azo dyes, azomethine dyes, indoaniline dyes, oxonol dyes, carbocyanine dyes, styryl dyes, triphenylmethane dyes, etc. Taking into consideration stability to development processing, light fastness, and effects on photographic performance such as desensitization, fogging, and staining, preferred dyes are used from anthraquinone dyes, azo dyes, azomethine dyes, and indoaniline dyes. Preferred compounds are described in JP-A No. 62-276539, page 3, upper left column, line 5 to page 9, upper left column, line 9. Such dyes can be dispersed in emulsion layers and other hydrophilic colloid layers (e.g., intermediate layers, protective layers, antihalation layers, filter layers) by various known methods, and specific examples are described in JP-A No. 62-276539, page 9, upper left column, line 14 to page 10, lower left column, line 20.

The amount of sensitizing dye added is preferably 0.5 mmol or more and less than 4 mmol, more preferably 0.5 mmol or more and less than 1.5 mmol, per mole of silver halide. Specific examples of sensitizing dyes include II-1 to II-47 described on pages 5 to 8 of JP-A No. 2-68539.

Furthermore, plasticizers such as polymers and emulsions can be incorporated into the emulsion layers of the silver halide photographic light-sensitive material of the present disclosure to improve pressure characteristics. For example, British Patent No. 738618 discloses heterocyclic compounds, British Patent No. 738637 discloses alkyl phthalates, British Patent No. 738639 discloses alkyl esters, U.S. Patent No. 2,960,404 discloses polyhydric alcohols, U.S. Patent No. 3,121,060 discloses carboxyl alkyl celluloses, Japanese Patent Laid-Open No. 49-5017 discloses paraffins and carboxylic acid salts, and Japanese Patent Publication No. 53-28086 discloses alkyl acrylates and organic acids. These methods can also be used in the present disclosure.

[0165] 10) Hydrophilic colloids Gelatin is advantageously used as a binder or protective colloid that can be used in the emulsion layers, intermediate layers, and surface protective layers of the silver halide photographic light-sensitive material according to the present disclosure, but other hydrophilic colloids can also be used.

Among these, it is preferable to use gelatin in combination with dextran or polyacrylamide having an average molecular weight of 100,000 or less. The methods described in JP-A-63-68887 and JP-A-63-149641 can also be used in the present disclosure.

[0167] 11) Hardeners The photographic emulsion and non-photosensitive hydrophilic colloid may contain an inorganic or organic hardener. Examples of hardeners include those described in JP-A No. 2-68539, page 12, lower left column, line 17 to page 13, upper right column, line 6. Specific examples of such compounds that can be used alone or in combination include chromium salts (chrome alum, chromium acetate, etc.), aldehydes (formaldehyde, glyoxal, dimethicone aldehyde, etc.), N-methylol compounds (dimethylol urea, methylol dimethyl dantoin, etc.), dioxane derivatives (2,3-dihydroxydioxane, etc.), active vinyl compounds (1,3,5-triacryloyl-hexahydro-s-triazine, bis(vinylsulfonyl)methyl ether, N,N'-methylenebis-(β-(vinylsulfonyl)propionamide)), active halogen compounds (2,4-dichloro-6-hydroxy-s-triazine, etc.), mucohalogen acids (mucochloric acid, mucophenoxychloroic acid, etc.), isoxazoles, dialdehyde starch, and 2-chloro-6-hydroxytriazinylated gelatin. Of these, the active vinyl compounds described in JP-A Nos. 53-41221, 53-57257, 59-162546 and 60-80846 and the active halides described in US Pat. No. 3,325,287 are preferred.

[0168] As the hardener, polymeric hardeners can also be effectively used. Examples of polymeric hardeners include polymers having an aldehyde group such as dialdehyde starch, polyacrolein, and acrolein copolymers described in U.S. Pat. No. 3,396,029, polymers having an epoxy group described in U.S. Pat. No. 3,623,878, polymers having a dichlorotriazine group described in U.S. Pat.

The hydrophilic colloid layer in the silver halide photographic light-sensitive material according to the present disclosure is preferably hardened with such a hardener so that the swelling ratio in water is 300% or less, particularly 230% or less.

[0169] 12) Support Examples of supports include those described in JP-A No. 2-68539, page 13, upper right column, lines 7 to 20. Specifically, polyethylene terephthalate film or cellulose triacetate film is preferred. To improve adhesion to the hydrophilic colloid layer, the surface of the support is preferably subjected to corona discharge treatment, glow discharge treatment, or ultraviolet irradiation treatment. Alternatively, a subbing layer made of a styrene-butadiene latex, vinylidene chloride latex, or the like may be provided, and a gelatin layer may be further provided thereon. Alternatively, a subbing layer made of an organic solvent containing a polyethylene swelling agent and gelatin may be provided. Surface treatment of these subbing layers can further improve adhesion to the hydrophilic colloid layer.

[0170] 13) Crossover Cut Method It is well known in the art that crossover light significantly reduces sharpness. As a means for keeping the crossover light of a photographic material to 12% or less, U.S. Pat. No. 4,130,429 and JP-A-61-116354 disclose methods for absorbing light of a wavelength that coincides with the emission wavelength of an X-ray fluorescent screen using a sensitizing dye or dye.

[0171] Furthermore, U.S. Pat. No. 4,800,150 discloses a technique in which a dye is present in the form of a microcrystalline dispersion between the support and the emulsion layer, thereby reducing crossover light to 10% or less. Japanese Patent Application Laid-Open No. 63-305345 discloses a technique in which an anionic dye is fixed in a specific layer using a cationic polymer latex, and Japanese Patent Application Laid-Open No. 1-166031 discloses a technique in which the dye fixing layer is an undercoat layer of the support. While any of these methods can be used in the photosensitive material of the present disclosure, it is preferred that the dye-colored layer be an undercoat layer, and that the dye be fixed by the method described in Japanese Patent Application Laid-Open No. 1-166031. It is particularly preferred that the dye be fixed in the undercoat layer in the form of a microcrystalline dispersion as described in U.S. Pat. No. 4,803,150. In the present disclosure, these methods can be combined as appropriate. Preferred dyes include those described in Japanese Patent Application Laid-Open No. 2-264944, from the lower left column on page 4 to the upper right column on page 9. As the mordant layer, those described in the lower right column to the upper right column of page 14 of JP-A No. 2-264944 can be used.

[0172] 14) Polyhydroxybenzenes Examples of polyhydroxybenzenes include those described in JP-A No. 3-39948, page 11, upper left column to page 12, lower left column, and European Patent Application Publication No. 452772A. Specific examples include the compound of formula (III) described in JP-A No. 8-39948, page 11, upper left column, and specific compounds thereof, compounds (III)-1 to 25, described in JP-A No. 8-39948, page 11, lower left column to page 12, lower left column. The amount of these polyhydroxybenzene compounds to be added is 5×10 per mol of silver halide. －１It is sufficient if the amount is less than 5×10 mol per mol of silver halide. －３ moles ~ 1 x 10 －１ The amount added is in moles.

[0173] The silver halide photographic light-sensitive material according to the present disclosure is composed of a silver halide emulsion layer (light-sensitive layer) containing light-sensitive silver halide grains on a support, and at least one non-light-sensitive hydrophilic colloid layer such as an intermediate layer, a surface protective layer, a back layer, a back surface protective layer, an antihalation layer, or a filter layer. However, there are no particular limitations on the emulsion sensitization method or various additives used, and those described in, for example, JP-A-2-68539 can be suitably used.

[0174] 15) Surface Protective Layer and Back Protective Layer The silver halide photographic light-sensitive material according to the present disclosure preferably has a surface protective layer and a back protective layer, which contain various chemicals with a hydrophilic colloid such as gelatin as a binder. When the main component of the layer is gelatin, a preservative or the like is necessary. Furthermore, it is preferable that the layer contains a matting agent, a lubricant, a plasticizer, an antistatic agent, a surfactant, a hardener, a thickener, a dye, a conductive substance, or the like, as needed.

[0175] 16) Development Processing Method As a development processing method for the silver halide photographic light-sensitive material according to the present disclosure, the methods described in JP-A No. 2-103037, page 16, upper right column, line 7 to page 19, lower left column, line 15, JP-A No. 2-115837, page 3, lower right column, line 5 to page 6, upper column, line 10, and JP-A No. 2000-112078, page 34, left column, line 42 to page 35, left column, line 2 can be used. Furthermore, for thermally developable light-sensitive materials, the methods described in JP-A No. 2001-255617, page 37, left column, line 40 to page 35, left column, line 43 can be used.

[0176] One embodiment of the silver halide photographic material according to the present disclosure is a photosensitive heat-developable photographic material. The technology for this is described in Japanese Patent No. 5,623,921, paragraphs 16 to 189. In this embodiment, the desired effect can be obtained when the surfactants described in paragraphs 181 to 183 of the publication are those described in the present application.

[0177] (Diffusion Transfer Type Silver Halide Photosensitive Material) The diffusion transfer type silver halide photosensitive material according to the present disclosure has a support and a layer on the support, the layer containing an ionic compound having an anionic structure represented by the following formula 1 (the ionic compound according to the present disclosure):

[0178]

[0179] In Formula 1, w represents an integer of 1 or more, x represents an integer of 2 or more, and Sil １ represents a substituent containing at least three Si atoms, and a plurality of Si １ may be the same or different, L １ represents a divalent linking group, and a plurality of L １ may be the same or different, and R represents an (x+w)-valent organic group containing a carbon atom.

[0180] Preferred embodiments of the ionic compound in the diffusion transfer type silver halide photographic light-sensitive material according to the present disclosure are the same as those of the ionic compound according to the present disclosure described above. The diffusion transfer type silver halide photographic light-sensitive material according to the present disclosure may contain one ionic compound according to the present disclosure alone, or two or more ionic compounds according to the present disclosure. The content of the ionic compound according to the present disclosure in the layer of the diffusion transfer type silver halide photographic light-sensitive material according to the present disclosure may be appropriately selected depending on the application, but is preferably 0.0001% by mass to 50% by mass, more preferably 0.001% by mass to 20% by mass, and particularly preferably 0.01% by mass to 10% by mass, relative to the total mass of the layer.

[0181] The layer may be any layer constituting the diffusion transfer type silver halide photographic light-sensitive material described below. Preferably, it is a layer that forms an air-liquid interface during coating, and more preferably, it is the outermost layer of the finally laminated photosensitive material. Specific examples include an intermediate layer in a substrate for a photosensitive sheet, the outermost layer of a substrate, an intermediate layer in a photosensitive sheet, a protective layer, and a temperature compensation layer in a cover sheet. Among these, the outermost layer of a substrate in a substrate for a photosensitive sheet, a protective layer in a photosensitive sheet, and a temperature compensation layer in a cover sheet are particularly preferred. Furthermore, in the diffusion transfer type silver halide photographic light-sensitive material according to the present disclosure, the layer containing the ionic compound according to the present disclosure may be one layer or two or more layers. The layer may contain various components contained in the diffusion transfer type silver halide photographic light-sensitive material described below.

[0182] The diffusion transfer type silver halide photographic light-sensitive material according to the present disclosure preferably comprises a light-sensitive sheet, a transparent cover sheet, and an alkaline processing composition-containing material spread between them.

[0183] [1] Alkali Processing Composition-Containing Body The alkali processing composition-containing body is uniformly spread on the photosensitive sheet after exposure to light, and has the functions of developing the photosensitive layer and, together with a light-shielding layer provided on the back side of the transparent support of the photosensitive sheet or in the photosensitive sheet, completely shielding the photosensitive layer from external light. Therefore, the alkali processing composition-containing body typically contains, in addition to alkali, a thickener, a light-shielding agent, and a developing agent, a development accelerator for controlling development, a development inhibitor for preventing deterioration of the developing agent, and an antioxidant for preventing deterioration of the developing agent.

[0184] (a) Alkali The alkali is not particularly limited as long as it can adjust the pH of the solution to 12 or higher. Examples of alkalis include alkali metal hydroxides (e.g., sodium hydroxide, potassium hydroxide, and lithium hydroxide), alkali metal phosphates (e.g., potassium phosphate), guanidines, and quaternary amine hydroxides (e.g., tetramethylammonium hydroxide). Among these, potassium hydroxide and sodium hydroxide are preferred.

[0185] (b) Developing Agent Any developing agent may be used as long as it cross-oxidizes the dye image-forming compound and does not substantially produce stains even when oxidized. A single developing agent may be used, or two or more developing agents may be used, or they may be used in the form of a precursor. Examples of developing agents include aminophenols and pyrazolidinones. Of these, pyrazolidinones are particularly preferred because they cause less staining. Specific examples of pyrazolidinones include 1-phenyl-3-pyrazolidinone, 1-p-tolyl-4,4-dihydroxymethyl-3-pyrazolidinone, 1-(3'-methyl-phenyl)-4-methyl-4-hydroxymethyl-3-pyrazolidinone, 1-phenyl-4-methyl-4-hydroxymethyl-3-pyrazolidinone, and 1-p-tolyl-4-methyl-4-hydroxymethyl-3-pyrazolidinone. The developing agent may be incorporated into the alkaline processing composition-containing material, or may be added to an appropriate layer of the photosensitive sheet.

[0186] (c) Light-blocking agent Any material having a light-blocking function can be used as a light-blocking agent without any particular limitation. Examples of light-blocking agents include carbon black and the decomposable dyes described in U.S. Pat. No. 4,615,966. Of these light-blocking agents, carbon black is preferred. Carbon black is not limited to carbon black obtained by a specific manufacturing method, and may be obtained by any manufacturing method. Examples of methods for manufacturing carbon black include the channel method described in Donnel Voet "Carbon Black" MarcelDekker, Inc. (1976), as well as the thermal method and the furnace method.

[0187] When using carbon black as a light-blocking agent, it is preferable to prepare the carbon black in advance as an aqueous dispersion. Aqueous dispersions of carbon black are widely used in paints, inks, cosmetics, and photographic photosensitive materials, as black materials, or light-blocking materials. To prepare an aqueous dispersion of carbon black, carbon black is added to water containing a suitable dispersant, and the carbon black is coarsely dispersed using a coarse disperser (e.g., a high-speed stirring disperser such as the Dissolver described in Japanese Patent Application Publication No. 54-36045) to obtain an average particle size of approximately 10 μm to 100 μm. The particle size is then further reduced using a fine disperser (e.g., a sand grinder, homogenizer, colloid mill, etc.). This process allows for the production of an aqueous dispersion of carbon black having an average particle size of approximately 0.1 μm to 10 μm. Alternatively, as described in Japanese Patent Application Publication No. 58-52362, carbon black may be dispersed in an aqueous solution containing an organic solvent, followed by removal of the organic solvent to obtain an aqueous dispersion of carbon black.

[0188] Preferred dispersants include those described in "Dispersion Technology Comprehensive Data Collection" (Published by the Business Development Center), pages 255 to 257 and 501 to 539. An example of a commercially available dispersant is Demol N (trade name, manufactured by Kao Corporation).

[0189] The type and / or amount of the dispersant affects the sodium ion content, which will be described later. The type and / or amount of the dispersant must be determined so as to satisfy (a) the condition of imparting sufficient dispersibility to the light-shielding agent, as well as (b) the condition of the sodium ion content. To satisfy both the conditions of dispersibility and the sodium ion content, the blending amount of the dispersant is preferably 2% by mass to 100% by mass of the light-shielding agent.

[0190] (d) Optical Density The optical density of the alkali treatment composition-containing body is preferably 47 or more, more preferably 50 or more, and particularly preferably 55 or more. When the optical density is 47 or more, sufficient light-shielding properties are obtained and spot fogging is suppressed. It is preferable to determine the amount of the light-shielding agent to be blended so that the optical density is 47 or more. Although it depends on the type of light-shielding agent used, it is preferable to set the amount of the light-shielding agent to about 10% by mass to 40% by mass in order to achieve an optical density of 47 or more.

[0191] (e) Sodium ion content The sodium ion content of the alkaline processing composition-containing material in a spread state is preferably 0.4 g / m ２ The sodium ion content is 0.35 g / m ２ More preferably, it is 0.25 g / m or less. ２ It is particularly preferred that:

[0192] The sodium ion content is primarily determined by the dispersant for the light-blocking agent and the thickener. Sodium carboxymethylcellulose is particularly preferred as a thickener. Sodium carboxymethylcellulose has sufficient spreadability and stability. The sodium ion content can be reduced by using polyvinyl alcohol, hydroxyethyl cellulose, or an alkali metal salt of carboxymethylcellulose other than sodium as a thickener. However, these do not have sufficient spreadability and stability, so their use alone is not appropriate. Therefore, it is preferable to use sodium carboxymethylcellulose primarily as a thickener, and to use polyvinyl alcohol, hydroxyethyl cellulose, or an alkali metal salt of carboxymethylcellulose other than sodium in combination.

[0193] Sodium ion content is 0.4 g / m ２It is preferable to adjust the degree of etherification of sodium carboxymethyl cellulose and the amount of addition so that the degree of etherification of sodium carboxymethyl cellulose is as follows: The degree of etherification of sodium carboxymethyl cellulose is preferably 0.5 to 2.7, and more preferably 1.0 to 2.4. The amount of sodium carboxymethyl cellulose added is preferably 1% by mass to 15% by mass, and more preferably 2% by mass to 10% by mass.

[0194] An alkali processing composition-containing material satisfying the above optical density and sodium ion content exhibits excellent light-blocking properties and dye transfer properties even when thinly spread on a photosensitive sheet. In this specification, "thinly spread" means that the alkali processing composition-containing material is spread on the photosensitive sheet to a thickness of 10 μm to 80 μm. The preferred spread thickness is 10 μm to 70 μm, and more preferably 20 μm to 60 μm.

[0195] [2] Photosensitive Sheet (a) First Transparent Support The support of the photosensitive sheet may be any of those commonly used for photographic materials. The support of an integrated color diffusion transfer film unit must be transparent. The support is preferably smooth. Examples of support materials include cellulose acetate, polystyrene, polyethylene terephthalate, and polycarbonate. To prevent light piping, the support preferably contains a trace amount of dye or pigment such as titanium oxide. The thickness of the support of the photosensitive sheet is preferably 25 μm to 350 μm, more preferably 50 μm to 210 μm, and particularly preferably 70 μm to 150 μm. A primer layer (undercoat layer) is preferably provided on the front side of the support. A curl-balancing layer or an oxygen-blocking layer can be provided on the back side of the support as needed. The oxygen-blocking layer can be provided by referring to the description in JP-A-56-78833.

[0196] (b) Image-receiving layer The image-receiving layer (dye image-receiving layer) of the photosensitive sheet preferably contains a mordant and a hydrophilic colloid. The image-receiving layer may be a single layer or may be a laminate of layers having different mordanting powers. Single-layer and multi-layer image-receiving layers can be provided by referring to the description in JP-A-61-252551.

[0197] The mordant is preferably a polymer mordant. The polymer mordant is a polymer containing a secondary and / or tertiary amino group, a polymer having a nitrogen-containing heterocyclic moiety, a polymer containing a quaternary cation, or the like, and preferably has a molecular weight of 5,000 or more, particularly preferably 10,000 or more. The coating amount of the mordant is preferably 0.5 g / m ２ ~10g / m ２ and more preferably 1 g / m ２ ~5g / m ２ and particularly preferably 2 g / m ２ ~4g / m ２ is.

[0198] Examples of hydrophilic colloids include gelatin, polyvinyl alcohol, polyacrylamide, polyvinylpyrrolidone, etc. A preferred hydrophilic colloid is gelatin.

[0199] The image-receiving layer may contain a discoloration inhibitor. There are no particular restrictions on the discoloration inhibitor, but those described in, for example, JP-A Nos. 62-30620, 62-30621, and 62-215272 can be used. The thickness of the image-receiving layer may be the same as that of an image-receiving layer in a general color diffusion transfer film unit.

[0200] (c) White Reflective Layer The white reflective layer of the photosensitive sheet forms a white background for the color image and usually contains a white pigment and a hydrophilic binder.

[0201] The whiteness of the white reflective layer is determined by the type of pigment, the mixing ratio of the pigment and the binder, and the coating amount of the pigment. When the white pigment is titanium dioxide, the content of titanium dioxide is preferably 5 g / m ２ ~40g / m ２ and more preferably 10 g / m ２ ~25g / m ２ is.

[0202] The light reflectance of the white reflective layer is preferably 70% or more, and more preferably 78% to 85% for light with a wavelength of 540 nm.

[0203] Examples of white pigments include barium sulfate, zinc oxide, barium stearate, silver flakes, silicates, alumina, zirconium oxide, sodium zirconium sulfate, kaolin, mica, and titanium dioxide. Non-film-forming polymer particles such as polystyrene can also be used as white pigments. Among these, titanium dioxide is preferred, with rutile titanium dioxide being particularly preferred. White pigments may be used alone or in combination of two or more. Using two or more white pigments makes it easier to achieve a preferred reflectance value for the white reflective layer.

[0204] The white pigment is preferably surface-treated with alumina, silica, zinc oxide, etc., and more preferably has a surface treatment amount of 5% or more. A white reflective layer containing a surface-treated white pigment exhibits high reflectance.

[0205] Examples of commercially available titanium dioxide include Ti-pure R931 (trade name) from DuPont and those described in Research Disclosure (RD) No. 15162.

[0206] Examples of the hydrophilic binder include alkali-permeable polymer matrices such as gelatin and polyvinyl alcohol, and cellulose derivatives such as hydroxyethyl cellulose and carboxymethyl cellulose. When the binder is gelatin, the mass ratio of the white pigment to the gelatin is preferably 1 / 1 to 20 / 1, and more preferably 5 / 1 to 10 / 1.

[0207] The white reflective layer preferably contains an anti-fading agent. There are no particular restrictions on the anti-fading agent, but the anti-fading agents described in, for example, Japanese Patent Publication Nos. 62-30620 and 62-30621 can be used.

[0208] (d) Light-shielding layer The light-shielding layer is provided between the white reflective layer and the photosensitive layer. The light-shielding layer preferably contains a light-shielding agent and a hydrophilic binder.

[0209] The light-shielding agent may be any of those described in the above section [1] (c) Light-shielding agent of the alkali processing composition-containing composition. The content of the light-shielding agent varies depending on the sensitivity of the light-sensitive material to be shielded from light, but generally, an optical density of about 5 to 10 is preferred.

[0210] The binder for the light-shielding layer may be any material that can disperse a light-shielding agent such as carbon black, etc. A preferred binder is gelatin.

[0211] There are no particular limitations on the thickness of the light-shielding layer, as long as it exhibits sufficient light-shielding ability and does not make the photosensitive sheet too thick.

[0212] (e) Photosensitive layer The photosensitive layer is adjacent to the light-shielding layer and preferably contains a dye image-forming compound and a silver halide emulsion. The photosensitive layer may be a multilayer consisting of a silver halide emulsion layer and a dye image-forming compound layer, or a single layer containing both a silver halide emulsion and a dye image-forming compound. The multilayer case will be explained below, but the same applies to a single layer case.

[0213] (f) Dye Image-Forming Compounds Dye image-forming compounds include yellow dye-forming compounds, magenta dye-forming compounds, and cyan dye-forming compounds.

[0216] A dye image-forming compound that forms a dye by coupling can also be used as the dye image-forming compound. Examples of dye image-forming compounds that form a dye by coupling are described in JP-A Nos. 8-286340, 9-152705, 10-186564, and 10-293388.

[0217] Positive dye image-forming compounds can also be used. Examples of positive dye image-forming compounds are described in JP-A Nos. 4-156542, 4-155332, 4-172344, 4-172450, 4-318844, 4-356046, 5-45824, 5-45825, 5-53279, 5-107710, 5-241302, 5-107708, 5-232659, and U.S. Pat. No. 5,192,649. A positive dye image-forming compound is preferably combined with a negative silver halide emulsion, which will be described later.

[0221]

[0222] (g) Silver halide emulsions The silver halide emulsion may be a negative type silver halide emulsion in which a latent image is formed mainly on the surface of the silver halide grains, or an internal latent image type direct positive silver halide emulsion in which a latent image is formed inside the silver halide grains. Internal latent image type direct positive silver halide emulsions include, for example, so-called "conversion type emulsions" which are made by utilizing the difference in solubility of silver halide, and "core / shell type emulsions" which are made by doping metal ions or chemically sensitizing, or both, silver halide core grains, and at least the photosensitive sites of the core grains are covered with an outer shell of silver halide. These emulsions are described in U.S. Pat. These compounds are described in the specifications of, for example, British Patent Nos. 2,592,250, 3,206,313, British Patent No. 1,027,146, U.S. Patent Nos. 3,761,276, 3,935,014, 3,447,927, 2,297,875, 2,563,785, 3,551,662, 4,395,478, West German Patent No. 2,728,108, and U.S. Patent No. 4,431,730.

[0223] When an internal latent image type direct positive silver halide emulsion is used, it is necessary to provide surface fog nuclei after imagewise exposure using light or a nucleating agent. Examples of nucleating agents include hydrazines described in U.S. Pat. Nos. 2,563,785 and 2,588,982, hydrazines and hydrazones described in U.S. Pat. No. 3,227,552, heterocyclic quaternary salt compounds described in British Patent No. 1,283,835, JP-A-52-69613, U.S. Pat. Nos. 3,615,615, 3,719,494, 3,734,738, 4,094,683 and 4,115,122, and heterocyclic quaternary salt compounds having a nucleating substituent in the dye molecule described in U.S. Pat. No. 3,718,470. Sensitizing dyes, U.S. Patent Nos. 4,030,925, 4,031,127, 4,245,037, 4,255,511, 4,266,013, 4,276,364, and British Patent No. 2,012,443, etc., described in thiourea-bonded acylhydrazine compounds, U.S. Patent Nos. 4,080,270, 4,278,748, and British Patent No. 2,011,391B, etc., described in heterocyclic groups (thioamide rings, triazole rings, tetrazole rings, etc.), and acylhydrazine compounds bonded as an adsorption group can be used. In order to reduce the sensitivity of re-reversal negative images and increase the reversal positive sensitivity, it is also preferable to use metal complexes described in JP-A-2002-40607 and JP-A-2003-107616. As a preferred method for producing a negative silver halide emulsion, the method described in JP-A No. 2006-113291 can be preferably used.

[0224] Spectral sensitizing dyes can be used in combination with silver halide emulsions, specific examples of which are described in JP-A-59-180550, JP-A-60-140335, RD17029, U.S. Pat. Nos. 1,846,300, 2,078,233, 2,089,129, 2,165,338, 2,231,658, 2,917,516, 3,352,857, 3,411,916, 2,295,276, and U.S. Pat. Nos. 2,481,698, 2,688,545, 2,921,067, 3,282,933, 3,397,060, 3,660,103, 3,335,010, 3,352,680, 3,384,486, 3,623,881, 3,718,470, and 4,025,349.

[0225] (h) Photosensitive Sheet Configuration The photosensitive sheet preferably has at least three silver halide emulsion layers with different color sensitivities and at least two color-mixing prevention layers containing a non-diffusible reducing agent located between the silver halide emulsion layers. To impart different color sensitivities to the at least three silver halide emulsion layers, it is effective and preferable to use the above-mentioned spectral sensitizing dyes with different absorption wavelength distributions. When imparting different color sensitivities to the silver halide emulsions, it is preferable that the spectral sensitivity distributions of the silver halide emulsions do not overlap as much as possible, but they do not need to be completely separated. When there is a relationship between the sensitivity of one emulsion layer at a specific wavelength that is at least twice that of at least two other silver halide emulsion layers, the color sensitivities can be considered to be different. It is desirable that the sensitivity relationship between the at least three silver halide emulsion layers be such that the sensitivity of one emulsion layer at a specific wavelength is preferably at least 5 times, more preferably at least 10 times, that of the other two silver halide emulsion layers. There are no particular limitations on the wavelengths that can establish these relationships, and any of the wavelengths in the visible, ultraviolet, or infrared ranges may be used. However, it is preferred that the silver halide emulsions in the at least three silver halide emulsion layers be selected from silver halide emulsions that are sensitive to any of blue, green, red, or infrared light.

[0226] The emulsion and the dye image-forming compound may be in separate layers, or may be contained in a single layer. When the dye image-forming compound has absorption in the spectral sensitivity region of the emulsion combined with it when coated, a separate layer is preferred.

[0227] The emulsion layer may be composed of emulsions having different sensitivities. Furthermore, any layer may be provided between the emulsion layer and the dye image-forming compound layer. For example, the density of the color image can be increased by providing a layer containing a nucleating development accelerator as described in JP-A-60-173541 or a partition wall layer as described in JP-B-60-15267, and the sensitivity of the photosensitive sheet can be increased by providing a reflective layer. The reflective layer is a layer containing a white pigment and a hydrophilic binder, with titanium oxide being preferred as the white pigment and gelatin being preferred as the hydrophilic binder. The coating amount of titanium oxide is 0.1 g / m ２~8g / m ２ It is preferable that the density is 0.2 g / m ２ ~4g / m ２ An example of the reflective layer is described in JP-A-60-91354.

[0228] In the case of a multilayer photosensitive layer, it is preferred that a blue-sensitive emulsion combination unit, a green-sensitive emulsion combination unit, and a red-sensitive emulsion combination unit are arranged in this order from the exposed side. Any layer can be provided between each emulsion layer unit as needed.

[0229] (i) Color-mixing prevention layer In order to prevent the undesirable influence of the development effect of one emulsion layer on other emulsion layer units, it is preferable to have a color-mixing prevention layer containing a non-diffusible reducing agent located between emulsion layers. At least one color-mixing prevention layer is required between each emulsion layer, so it is preferable that the photosensitive sheet has at least two color-mixing prevention layers.

[0230] Any known compound can be preferably used as the non-diffusible reducing agent in the color-mixing preventing layer. For example, it is preferable to use the high-molecular-weight redox compounds described in JP-A-5-333501, the phenidone and hydrazine compounds described in WO 98 / 33760 and U.S. Pat. No. 4,923,787, and the redox compounds described in German Patent Application Publication No. 19618786-A1, European Patent Application Publication No. 839623-A1, European Patent Application Publication No. 842975-A1, German Patent Application Publication No. 19806846-A1, and French Patent Application Publication No. 2760460-A1. It is also preferable to use the lactones described in JP-A-2000-122243. Particularly preferred non-diffusible reducing agents for use in the color-mixing preventing layer are selected from non-diffusible hydroquinone derivatives, sulfonamidophenol derivatives, sulfonamido naphthol derivatives, and lactones. In particular, non-diffusible hydroquinone derivatives are preferred, and dialkylhydroquinone derivatives are particularly preferred. Here, the alkyl group includes a substituted or unsubstituted alkyl group, and the substituent is not particularly limited as long as it does not inhibit the "non-diffusibility" of the compound. Specific examples include an aryl group, an acyl group, an alkoxycarbonyl group, and an aryloxycarbonyl group. The total number of carbon atoms in the "dialkyl group" is preferably 12 or more, and more preferably 16 or more.

[0231] The molecular weight of the non-diffusible reducing agent is preferably 350 or more, more preferably 390 or more, and particularly preferably 500 or more. When the color-mixing inhibitor is a polymer, the molecular weight is expressed as a number-average molecular weight. The upper limit of the molecular weight of the non-diffusible reducing agent is not particularly limited when the non-diffusible reducing agent is a polymer, but when it is a compound other than a polymer, it is preferably about 1,000 or less. The optimal amount of non-diffusible reducing agent contained in at least two color-mixing prevention layers disposed between each silver halide emulsion layer varies depending on the coating amount, shape, grain size, and target maximum color density of the silver halide emulsion used. However, too much non-diffusible reducing agent results in a decrease in color density and a delay in image formation time, while too little non-diffusible reducing agent results in cloudy color hues. Therefore, the amount of non-diffusible reducing agent should be determined taking these factors into consideration. The decrease in color density resulting from a reduction in the coated silver amount can be effectively suppressed by setting the coating amount of silver halide to the non-diffusible reducing agent at a specific ratio and using a specific amount of negative-working silver halide emulsion as the silver halide emulsion. The total coating mole number of silver halide is in the range of 5 to 10 times the total coating mole number of the non-diffusible reducing agent used in the color-mixing preventing layer. The total coating mole number of the non-diffusible reducing agent is preferably 0.5 mmol / m ２ ~1.5mmol / m ２ more preferably in the range of 0.8 mmol / m ２ ~1.2mmol / m ２ Specific examples of the non-diffusible reducing agent are given below, but the present disclosure is not limited thereto.

[0232]

[0233] The non-diffusible reducing agent is preferably dissolved in a high-boiling organic solvent and present in the color-mixing prevention layer as fine oil droplets obtained by emulsification and dispersion. The high-boiling organic solvent preferably has a dielectric constant in the range of 4.0 to 8.0. The high-boiling organic solvent may be a mixture of two or more types. Examples of preferred high-boiling organic solvents include esters such as phthalates and phosphates, organic acid amides, and ketones. The dielectric constant is measured using a transformer bridge method (TRS-10T, manufactured by Ando Electric Co., Ltd.) at 25°C and 10 kHz. The high-boiling organic solvent preferably has a boiling point of 140°C or higher and a melting point of 100°C or lower, and more preferably a boiling point of 160°C or higher and a melting point of 70°C or lower. The high-boiling organic solvent may be solid at room temperature; in this case, the dielectric constant is measured in the liquid (supercooled state). The amount (mass ratio) of the high-boiling organic solvent to the non-diffusible reducing agent in the color-mixing prevention layer is preferably 0.3 to 20, more preferably 0.5 to 10, and even more preferably 1 to 8.

[0234] There are no particular limitations on the thickness of the photosensitive layer, as long as it provides sufficient color reproducibility and does not make the photosensitive sheet too thick.

[0235] (j) Others The photosensitive sheet may have an anti-irradiation layer, a UV absorber layer, a protective layer, etc., as needed. The thickness of the photosensitive sheet is not particularly limited as long as it does not make the color diffusion transfer film unit too thick.

[0236] [3] Transparent Cover Sheet (a) Second Transparent Support The support for the transparent cover sheet may be any smooth transparent support commonly used for photographic materials. Preferred supports include cellulose acetate, polystyrene, polyethylene terephthalate, polycarbonate, etc. The support preferably contains a trace amount of dye to prevent light piping. It is also preferred to provide an undercoat layer on the support.

[0237] (b) Layer with Neutralizing Function The layer with neutralizing function (neutralizing layer) is a layer containing an acidic substance in an amount sufficient to neutralize the alkali introduced from the alkaline processing composition-containing body. If necessary, it may have a multilayer structure comprising layers such as a neutralization rate adjusting layer (neutralization timing layer) and an adhesion enhancing layer.

[0238] Preferred acidic substances are substances containing an acidic group having a pKa of 9 or less (or a precursor group that generates an acidic group having a pKa of 9 or less upon hydrolysis), and more preferred acidic substances are higher fatty acids such as oleic acid described in U.S. Pat. No. 2,983,606, polymers of acrylic acid, methacrylic acid, or maleic acid, and their partial esters or acid anhydrides as disclosed in U.S. Pat. No. 3,362,819, copolymers of acrylic acid and acrylic acid esters as disclosed in French Patent No. 2,290,699, and latex-type acidic polymers as disclosed in U.S. Pat. No. 4,139,383 and RD No. 16102 (1977). Additionally, acidic substances disclosed in US Pat. No. 4,088,493, JP-A Nos. 52-153739, 53-1023, 53-4540, 53-4541, and 53-4542 are also preferred.

[0239] Other examples of acidic polymers include copolymers of vinyl monomers such as ethylene, vinyl acetate, and vinyl methyl ether with maleic anhydride and their n-butyl esters, copolymers of butyl acrylate with acrylic acid, cellulose, and acetate hydrogen phthalate.

[0240] The acidic polymer can be used in combination with a hydrophilic polymer. Examples of the hydrophilic polymer include polyacrylamide, polymethylpyrrolidone, polyvinyl alcohol (including partially saponified products), carboxymethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, and polymethyl vinyl ether. Among these, polyvinyl alcohol is preferred. The acidic polymer may be mixed with a polymer other than the hydrophilic polymer, such as cellulose acetate.

[0241] The amount of acidic polymer to be applied is determined by the amount of alkali in the alkaline processing composition-containing material. The equivalent ratio of acidic polymer to alkali per unit area is preferably 0.9 to 2.0. If the amount of acidic polymer is too small, the hue of the transferred dye will change and staining will occur on the white background. If the amount of acidic polymer is too large, problems such as changes in hue or reduced lightfastness will occur. A more preferred equivalent ratio is 1.0 to 1.3. If the amount of hydrophilic polymer to be mixed is too large or too small, photographic quality will be reduced. The mass ratio k of hydrophilic polymer to acidic polymer is preferably 0.01 to 10, more preferably 0.1 to 3.0.

[0242] Additives can be incorporated into the neutralization layer for various purposes. For example, a general film-hardening agent may be added to the neutralization layer, or a polyhydroxyl compound such as polyethylene glycol, polypropylene glycol, or glycerin may be added to reduce film brittleness. Other additives, such as antioxidants, fluorescent brighteners, development inhibitors, and their precursors, may also be added as needed.

[0243] For the neutralization timing layer used in combination with the neutralization layer, useful are polymers that reduce alkali permeability, such as gelatin, polyvinyl alcohol, partially acetalized polyvinyl alcohol, cellulose acetate, and partially hydrolyzed polyvinyl acetate; latex polymers that increase the activation energy of alkali permeation, in which a small amount of hydrophilic comonomer, such as an acrylic acid monomer, is copolymerized; and polymers having a lactone ring.

[0244] Among these, timing layers using cellulose acetate disclosed in JP-A-54-136328, U.S. Pat. Nos. 4,267,262, 4,009,030, and 4,029,849, etc.; acrylic resins disclosed in JP-A-54-128335, JP-A-56-69629, JP-A-57-6843, U.S. Pat. Nos. 4,056,394, 4,061,496, 4,199,362, 4,250,243, 4,256,827, and 4,268,604, etc. Particularly useful are latex polymers copolymerized with a small amount of hydrophilic comonomers such as acids; polymers having monoacrylates or monomethacrylates of polyhydric alcohols as disclosed in JP-A-11-2890; polymers having lactone rings as disclosed in U.S. Pat. No. 4,229,516; and polymers disclosed in JP-A-56-25735, JP-A-56-97346, JP-A-57-6842, EP-A-31,957-A1, EP-A-37,724-A1, EP-A-48,412-A1, and the like.

[0245] Additionally, those described in the following documents can also be used: U.S. Pat. No. 3,421,893, U.S. Pat. No. 3,455,686, U.S. Pat. No. 3,575,701, U.S. Pat. No. 3,778,265, U.S. Pat. No. 3,785,815, U.S. Pat. No. 3,847,615, U.S. Pat. No. 4,088,493, U.S. Pat. No. 4,123,275, U.S. Pat. No. 4,148,653, U.S. Pat. No. 4,201,587, U.S. Pat. No. 4,288,523, U.S. Pat.

[0246] The neutralization timing layer may contain a development inhibitor and / or a precursor thereof disclosed in U.S. Pat. No. 4,009,029, West German Patent Application (OLS) No. 2,913,164, West German Patent Application Publication No. 3,014,672, JP-A-54-155837, JP-A-55-138745, etc., a hydroquinone precursor disclosed in U.S. Pat. No. 4,201,578, other photographic additives or precursors thereof, etc. Furthermore, providing an auxiliary neutralization layer as described in JP-A-63-168648 and JP-A-63-168649 is effective in reducing changes in transfer density over time after processing.

[0247] The neutralization timing layer may contain a plurality of these materials. A plurality of materials may be contained in one layer, or may be contained in each of a plurality of layers.

[0248] (c) Other Layers The transparent cover sheet may have, in addition to the layer having a neutralizing function, layers having auxiliary functions such as a backing layer, a protective layer, and a filter dye layer.

[0249] The backing layer is provided to adjust curl and provide slippage. The backing layer may contain a filter dye. The protective layer is primarily used to prevent adhesion to the back surface of the cover sheet and to the protective layer of the photosensitive material when the photosensitive material and the cover sheet are superimposed. If the transparent cover sheet contains a dye, the sensitivity of the photosensitive layer can be adjusted. A filter dye may be added to the support of the cover sheet, a layer with a neutralizing function, the backing layer, the protective layer, a capture mordant layer, etc. Alternatively, a layer containing only a filter dye may be provided.

[0250] The diffusion transfer type silver halide photographic light-sensitive material according to the present disclosure may contain other known additives in each layer.

[0251] The present disclosure will be explained in more detail below with reference to examples. The materials, amounts used, ratios, processing details, processing procedures, etc. shown in the following examples can be changed as appropriate without departing from the spirit of the present disclosure. Therefore, the scope of the present disclosure is not limited to the specific examples shown below. In the examples, "%" and "parts" mean "% by mass" and "parts by mass," respectively, unless otherwise specified.

[0253]

[0254] In a 300 mL three-neck flask equipped with a stirrer, a condenser, a nitrogen inlet tube, and a thermometer, 19.62 g of diallyl fumarate and 71.3 g of 2-propanol (iPrOH) were added, and the flask was purged with nitrogen. Sodium hydrogen sulfite (NaHSO ) diluted with 24.7 g of ion-exchanged water was added to the flask. ３ 10.4 g of 2-propanol and water were distilled off under reduced pressure, and then 150 g of ethyl acetate was added and stirred, and the precipitated solid was collected by filtration. The obtained solid was dispersed and washed in 150 g of ethyl acetate for 1 hour, filtered, and dried to obtain 20.5 g of a white solid of intermediate 1. The white solid was determined to be intermediate 1. １ This was confirmed by H-NMR.

[0257] 2.30 g (7.65 mmol) of intermediate 1, 162 mg (1.50 mmol) of 1,5-cyclooctadiene (cod), and 18 mL of methanol (MeOH) were weighed into a three-necked flask equipped with a stirrer, a condenser, a nitrogen inlet tube, and a thermometer. After replacing the atmosphere with nitrogen, the mixture was stirred at 45°C for 10 minutes. Chloro(1,5-cyclooctadiene)iridium(I) dimer ([IrCl(cod)] ２After stirring for an additional 10 minutes, 3.34 g (15.0 mmol) of 1,1,1,3,5,5,5-heptamethyltrisiloxane was added dropwise over 10 minutes. After the addition was complete, the reaction was carried out at 45°C for 2 hours. １ H-NMR spectroscopy confirmed that 1,1,1,3,5,5,5-heptamethyltrisiloxane had completely disappeared and that the target compound A1-1Na had been produced. After the methanol solvent was removed by distillation under reduced pressure, the residue was purified by silica gel column chromatography using ethyl acetate / methanol as a developing solvent, yielding 4.08 g (73% yield) of compound A1-1Na. １ H-NMR (MeOD): δ (ppm) = -0.11 ~ 0.12 ppm (42H), 0.36 ~ 0.48 ppm (4H), 1.50 ~ 1.66 ppm (4H), 2.85 ~ 3.15 ppm (4H), 3.52 ~ 4.08 ppm (5H)

[0258] (Example S2) <Synthesis of Compound A1-2Na>

[0259]

[0260] Compound A1-2Na was synthesized (yield 79%) in the same manner as compound A1-1Na, except that 3.34 g of 1,1,3,5,5,5-heptamethyltrisiloxane was used instead. １ H-NMR (MeOD): δ (ppm) = -0.10 ~ 0.10 ppm (42H), 0.42 ~ 0.56 ppm (4H), 1.54 ~ 1.70 ppm (4H), 2.85 ~ 3.15 ppm (4H), 3.90 ~ 4.10 ppm (5H)

[0262]

[0263] Compound A1-3Na was synthesized (yield 51%) in the same manner as in the synthesis of compound A1-1Na, except that 3.34 g of 1,1,3,5,5,5-heptamethyltrisiloxane was changed to 4.45 g of tris(trimethylsilyloxy)silane and the reaction was carried out at 60°C for 6 hours.１ H-NMR (MeOD): δ (ppm) = 0.02-0.20ppm (54H), 0.44-0.58ppm (4H), 1.60-1.80ppm (4H), 2.98-3.24ppm (4H), 3.96-4.22ppm (5H)

[0264] (Example S4) <Synthesis of Intermediate 2 and Intermediate 3>

[0265]

[0266] A 1000 mL three-neck flask equipped with a stirrer, a condenser, a nitrogen inlet tube, and a thermometer was charged with 499.0 g of ethyl acetate (AcOEt), 24.30 g of ion-exchanged water, and palladium / carbon (Pd / C, 5% palladium, approximately 55% wet with water), and the atmosphere was replaced with nitrogen. The three-neck flask was placed in an ice bath, and 100.0 g of 1,1,1,3,5,5,5-heptamethyltrisiloxane was added dropwise over 30 minutes. After the dropwise addition, the mixture was returned to room temperature and allowed to react for 3 hours. After the reaction, the palladium / carbon was removed by filtration through Celite, and the mixture was concentrated under reduced pressure using a rotary evaporator, yielding 100.5 g of a colorless, transparent liquid. This liquid was determined to be Intermediate 2. １The reaction mixture was confirmed by H-NMR. Subsequently, 99.0 g of the obtained intermediate 2 and 285 g of toluene were added to a 500 mL three-neck flask equipped with a stirrer, a condenser, a nitrogen inlet tube, and a thermometer, and the three-neck flask was immersed in an ice bath. After confirming that the temperature had reached 5°C or below, 32.5 g of pyridine was added dropwise, and stirring was continued until the temperature returned to 5°C or below. A separate solution was prepared by adding 18.4 g of toluene and 19.3 mL of dichloromethylsilane to a dropping funnel. The prepared solution was added dropwise to the three-neck flask over 30 minutes. After the addition was completed, the reaction solution was returned to room temperature and allowed to react for 3 hours. After the reaction, the precipitated solid was filtered off, and the resulting colorless, transparent liquid was subjected to a separation operation. The separation operation was performed twice using 350 mL of ion-exchanged water, and the organic layer was recovered. Magnesium sulfate was added to the organic layer, and the mixture was dehydrated for 30 minutes or more, and then concentrated under reduced pressure using a rotary evaporator. Crushed silica gel (Wakogel C-200, manufactured by Fujifilm Wako Pure Chemical Industries, Ltd.) was added to the resulting liquid, and the mixture was stirred and then filtered under suction to obtain a colorless, transparent liquid. This liquid was determined to be Intermediate 3. １ This was confirmed by H-NMR.

[0268]

[0269] Compound A1-4Na was synthesized (yield 74%) in the same manner as in the synthesis of Compound A1-1Na, except that 3.34 g of 1,1,3,5,5,5-heptamethyltrisiloxane was replaced with Intermediate 3 (7.79 g). １ H-NMR (MeOD): δ (ppm) = -0.12 ~ 0.10 ppm (90H), 0.42 ~ 0.56 ppm (4H), 1.54 ~ 1.70 ppm (4H), 2.85 ~ 3.15 ppm (4H), 3.84 ~ 4.12 ppm (5H)

[0270] (Examples 1-A to 1-D and Comparative Examples 1-A to 1-C: Evaluation of Surface Tension in Aqueous Solution) A sample for surface tension measurement was prepared by mixing 0.4 parts by mass of the compound synthesized above or a comparative compound, 1,000 parts by mass of ion-exchanged water, and 10 parts by mass of methanol. The prepared sample was kept at 40°C, and the surface tension was measured by the Wilhelmy method using a DY-300 automatic surface tensiometer manufactured by Kyowa Interface Science Co., Ltd., with a platinum plate as a probe. The measurement results are shown in Table 2.

[0271]

[0272] Comparative compounds C-1 and C-2 listed in Table 2 are shown below.

[0273]

[0274] (Examples 2-A to 2-H and Comparative Examples 2-A to 2-C: Preparation of composition for image-receiving film, production of film, and evaluation) As a coating liquid for the substrate-sixth layer, composition (P-A) was prepared containing the components shown in Table 3 per 1,000 g of the finished coating liquid. The remaining component in composition (P-A) was water.

[0275]

[0276] The composition (PA) shown in Table 3 had a gelatin coating amount of 0.29 g / m ２ It was applied so that

[0277] Separately, a substrate was prepared by laminating a backing layer on a polyethylene terephthalate support, followed by laminating a substrate-1 layer and a substrate-2 layer. Four layers, substrate-3 layer through substrate-6 layer, were simultaneously extruded onto a slide surface from a Giesser and coated onto this substrate at a coating speed of 60 m / min. After coating, the image-receiving film was stored at 25°C and 55% relative humidity for 7 days to harden. The sample thus obtained was designated image-receiving film substrate 101. The composition of each layer is shown in Table 4 below. Note that coarse particles with a diameter of 6 μm were intentionally added to the composition (A) above to forcibly evaluate its stability against cissing during coating. The inclusion of foreign matter in the coating environment or its peeling from the backing layer can cause cissing during coating. The addition of the coarse particles was for simulation purposes.

[0278]

[0279] Compositions (P-B) to (P-K) were prepared by changing only the type of compound in composition (P-A), which is the coating liquid for the substrate-6th layer. Details are shown in Table 5 below. Furthermore, image receiving film substrates 102 to 111 were each produced in the same manner as image receiving film substrate 101, except that only the type of substrate-6th layer coating liquid was changed. The obtained samples were evaluated as follows.

[0280] Evaluation 1) Coating surface condition - Evaluation of cissing resistance - The coated sample was ２ The frequency of cissing was evaluated by visual observation. The frequency of cissing for each sample was evaluated as a percentage of the number of cissings on the image receiving film substrate (silver halide photographic light-sensitive material) 101.

[0281] The evaluation results are also shown in Table 5.

[0306]

[0307] When a functional material (functional film) was produced using a composition containing an ionic compound according to the present disclosure, a functional film with excellent coating surface condition was obtained.

[0308] In the preparation of the above film substrate sample, a composition was prepared by removing the matting agent and the leveling agent introduced by the matting agent from the composition formulation of the substrate-sixth layer, and the same evaluation was performed. As a result, it was confirmed that a substrate in which the occurrence of cissing was suppressed could be formed in the sample using the ionic compound according to the present disclosure.

[0309] (Examples 3-A to 3-D and Comparative Examples 3-A to 3-C: Preparation of Composition, Preparation and Evaluation of Silver Halide Photosensitive Material) <Preparation of Substrate for Photosensitive Material> As shown in Table 3 of Examples 2-A to 2-H and Comparative Examples 2-A to 2-C above, a back layer was laminated on a polyethylene terephthalate support, and then substrate-1 to -6 layers were laminated to obtain a laminate substrate (Subs-1). In this case, the composition of the substrate-6 layer was the same as that of composition (A) of Comparative Example 2-A, but did not contain the matting agent (2) and the surfactant derived from the matting agent (surfactant (3)). After coating, this laminate substrate (Subs-1) was stored for 7 days under environmental conditions of 25°C and a relative humidity of 55% RH.

[0310] <Preparation of Photosensitive Material> A composition (QA) containing each of the components shown in Table 6 per 1,000 g of the finished coating solution was prepared as a coating solution for the 18th layer of a silver halide photosensitive material.

[0311]

[0312] The composition (Q-A) shown in Table 6 has a gelatin coating amount of 0.20 g / m ２ It was applied so that

[0313] Eighteen layers (layers 1 through 18) were simultaneously extruded onto a slide surface from a Giesser and coated at a coating speed of 60 m / min onto the substrate (Subs-1) prepared as described above. After coating, the photosensitive material was stored for 7 days at 25°C and 55% RH relative humidity to allow the hardening reaction to proceed. The sample thus obtained was designated Comparative Silver Halide Photosensitive Material 201. The composition of each layer is shown in Tables 7 to 9. Note that coarse particles with a diameter of 6 μm were intentionally added to the above composition (Q-A) to forcibly evaluate the stability against cissing during coating. By intentionally adding coarse particles, which are rarely mixed in, it was possible to evaluate cissing over a small coating area.

[0314]

[0315]

[0316]

[0317] Furthermore, compositions (Q-B) to (Q-G) were prepared by changing the compounds in composition (Q-A) as shown in Table 12 below. Silver halide photographic light-sensitive materials 202 to 207 were prepared in the same manner as silver halide photographic light-sensitive material 201, except that only the type of coating solution for the 18th layer was changed.

[0318] The obtained photosensitive material samples were evaluated as follows.

[0319] Evaluation) Coated Surface Condition The coated surface condition was evaluated based on two criteria: cissing and uniformity.

[0320] - Evaluation of repelling - The coated sample was ２ The frequency of cissing was evaluated by visual observation. The frequency of cissing for each sample was evaluated as a percentage of the number of cissings on the silver halide photographic light-sensitive material 201.

[0321] - Evaluation of uniformity - When the coating solution was extruded from the Giesser onto the slide surface and applied to the support, wind at a rate of about 2 m / sec was blown against the slide surface to forcibly coat the coating, making it easier to disturb the state of the coated surface. The coated photosensitive material was subjected to uniform exposure so that the post-processing density would be a gray of about 0.7, and then developed. The image was visually observed over an area 10 cm wide and 1 m long to evaluate the coating uniformity. Evaluation was primarily focused on streaky unevenness. The evaluation criteria are as follows: A: Unevenness due to wind is not discernible B: Unevenness due to wind is almost not discernible C: Unevenness due to wind is slightly discernible, but not problematic for practical use D: Streaky unevenness due to wind is discernible, and if the captured image is a uniform gray, it is a problem E: Streaky unevenness due to wind is discernible, and even if the captured image is not uniform and includes a pattern, it is a serious problem

[0322] The silver halide photographic light-sensitive material prepared above is a diffusion transfer type silver halide photographic light-sensitive material, and its processing method involves spreading a thin layer of processing solution between an exposed silver halide photographic light-sensitive material (photosensitive sheet) and a transparent cover sheet for development. The transparent cover sheet contains cellulose acetate and an acid polymer. The alkali in the processing solution causes hydrolysis of the cellulose acetate, increasing the alkali's permeability. For approximately 10 minutes, the processing solution maintains a high pH, ​​allowing development of the silver in the photosensitive material. Thereafter, neutralization by the acid polymer progresses, causing a rapid drop in pH within approximately 15 to 20 minutes, halting development. The processing solution was filled into a pressure-destructible container, and the container was crushed with a roller to achieve a spread thickness of the processing solution of 55 μm. The composition of the transparent cover sheet is shown in Table 10, and the composition of the processing solution is shown in Table 11. The evaluation results are shown in Table 12.
