BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dye fixing material used in forming a dye image by heating. Prior art and its problems Heat-developable photosensitive materials are well-known in this technical field, and the heat-developable photosensitive materials and their processes can be found in, for example, Fundamentals of Photographic Engineering (published by Corona Publishing, 1979).

A combination of a sulfonamidophenolic reducing agent and a 4-equivalent coupler has been proposed. However, in such a method, a reduced silver image and a color image are simultaneously generated in the exposed area after thermal development, so that the color image becomes cloudy. To solve this problem, there are methods to remove the silver image by liquid processing or to transfer only the dye to another layer, such as a sheet with an image-receiving layer. It has the disadvantage that it is not easy to transfer. Furthermore, the above-mentioned methods generally require a relatively long time for development, and the resulting images have the drawbacks of high fog and low density. In order to improve these drawbacks, the present inventors
Provided an image forming method using silver halide in which a mobile dye is formed in the form of an image and transferred to a dye fixing layer (Japanese Patent Application Laid-open No. 149046/1983, Japanese Patent Application Laid-open No. 59-1999)
154445, US Patent No. 59-165054, US Patent No. 59-180548, US Patent No. 4503137, US Patent No. 4474867, US Patent No.
4483914 and 4455363). In these methods, after exposure, a light-sensitive material containing silver halide and a dye-donating substance that forms or releases a mobile dye in chemical association with a reaction in which the silver halide is reduced to silver during high-temperature development. Alternatively, a movable dye is formed in the form of an image by heating at the same time as exposure, and this dye is transferred to the dye fixing material at the same time as the heat development or by heating after the heat development. In such a case, a base and/or a base precursor (hereinafter, A and/or B means at least one of A and B) may be included in the light-sensitive material or dye-fixing material as an image formation accelerator. There are many. In consideration of the stability of the light-sensitive material over time, it is desirable to include these in the dye-fixing material. However, it is necessary to add a base and/or a base precursor to the dye fixing material in a large amount (5×10 ^-4 mol/m ² or more, especially 2.5×
10 ^-3 mol/m ² or more), and this results in the problem that additives such as bases and base precursors precipitate on the surface of the dye fixing material over time. If a dye fixing material with such precipitation is used, dot-like unevenness will occur in the image. Furthermore, problems such as deterioration of the film over time (film peeling) and when peeling off the photosensitive material and dye fixing material after dye transfer, they adhere to each other and make it difficult to separate (film peeling occurs) are likely to occur. Purpose of the Invention The present invention prevents the precipitation of bases and/or base precursors when these additives are added, prevents film deterioration over time, and improves adhesion to photosensitive materials during diffusion transfer of dyes. The purpose of the present invention is to provide a dye-fixing material that has the following properties. DISCLOSURE OF THE INVENTION These objects are achieved by the invention described below. That is, the present invention is a dye-fixing material characterized by containing at least a base and/or a base precursor and a polyalkylene oxide or a derivative thereof on a support.

The number of polyalkylene oxide chains is not limited to one in the molecule, and two or more may be included. In this case, the individual polyalkylene oxide chains may consist of less than 10 alkylene oxide units, but the total number of alkylene oxide units in the molecule must be at least 10. If there is more than one polyalkylene oxide chain in the molecule, each of them may consist of different alkylene oxide units, such as ethylene side and propylene oxide.

In this method, a light-sensitive material contains a dispersion of a sparingly soluble metal salt compound, and a dye-fixing material contains a water-soluble compound that can form a complex with the metal ion as a base precursor, and both are mixed in the presence of water. Since a base can be generated during heat treatment in close contact, it is particularly effective in improving the storage stability of light-sensitive materials and dye-fixing materials over time.

Examples include mordants disclosed in No. 53-1024. In addition, mordants described in US Pat. No. 2,675,316 and US Pat. No. 2,882,156 can also be mentioned. In the present invention, the amount of polymer mordant applied depends on the amount of dye to be mordanted, the type and composition of the polymer mordant, and the image forming process used.
0.2 to 15, which can be easily determined by a person skilled in the art.
It is preferred to use g/m ² , especially 0.5 to 8 g/m ² . The molecular weight of the polymer used in the mordant is preferably from 1,000 to 1,000,000, particularly from 10,000 to 200,000. When the above polymer is used as a mordant in the present invention, the dye transfer density can be increased by using metal ions in the photosensitive material or dye fixing material. The metal ions are added to the mordant layer containing the mordant, or to the adjacent upper or lower layer. The metal ions used here are preferably colorless and stable against heat and light. That is, Cu ²⁺ , Zn ²⁺ , Ni ²⁺ , Pt ²⁺ , Pd ²⁺ ,
Polyvalent ions of transition metals such as Oo ³⁺ ions are preferred, and Zn ²⁺ is particularly preferred. This metal ion is usually in the form of water-soluble compounds, such as ZnSO ₄ ,
Zn(CH ₃ CO ₂ ) ₂ is added, and the amount added is 0.01
-5 g/ ^m2 , preferably 0.1-1.5 g/ ^m2 . In the dye-fixing material of the present invention, the binder is preferably hydrophilic, and transparent or translucent hydrophilic colloids are typical. For example, proteins such as gelatin, gelatin derivatives, polyvinyl alcohol, cellulose derivatives, natural substances such as starch, polysaccharides such as gum arabic, water-soluble polyvinyl compounds such as dextrin, dextran, pullulan, polyvinyl alcohol, polyvinylpyrrolidone, and acrylamide polymers. Synthetic polymeric substances such as these are used. Among these, it is more preferable to contain gelatin. The use of gelatin improves the applicability,
Set drying becomes possible. Then, the effects of the present invention are further improved. Although the mixing ratio of the binder and polyalkylene oxide or its derivative can be set arbitrarily, it is preferable that the mixing ratio is 0.01 to 1 (weight ratio). The dye-fixing material of the present invention is preferably made by being coated on a separate support from the photosensitive material that forms or releases a dye by heat development, but it is made by being coated on the same support. It's okay to be hit. There are two types of forms in which a light-sensitive material and a dye-fixing material are formed on separate supports: one is a peelable type and the other is a peelable type. In the former peel-off type, after image exposure, the coated surface of the photosensitive material and the coated surface of the dye-fixing material are overlapped, and after the transfer image is formed, the photosensitive material is immediately peeled off from the dye-fixing material. Depending on whether the final image is of a reflective type or a transmissive type, the support for the dye fixing material can be selected as an opaque support or a transparent support. Further, a white reflective layer may be coated if necessary. In the case of the latter type that does not require peeling, it is necessary to have a white reflective layer interposed between the photosensitive layer in the photosensitive material and the dye fixing layer in the dye fixing material. It may be coated on any of the materials. The support for the dye fixing material needs to be a transparent support. A typical example in which the light-sensitive material and the dye-fixing material are coated on the same support is one in which there is no need to peel the light-sensitive material from the image-receiving material after the transfer image is formed. In this case, a photosensitive layer, a dye fixing layer and a white reflective layer are laminated on a transparent or opaque support. Preferred embodiments include, for example, transparent or opaque support/photosensitive layer/white reflective layer/dye fixing layer/transparent support/dye fixing layer/white reflective layer/photosensitive layer. Another typical form in which a light-sensitive material and a dye-fixing material are coated on the same support includes, for example, Japanese Patent Application Laid-Open No. 56
−67840, Canadian Patent No. 674082, U.S. Patent No.
As described in No. 3730718, there is a form in which part or all of the photosensitive material is peeled off from the dye fixing material, and a peeling layer is coated at an appropriate position. The photosensitive material or dye fixing material may have a conductive heating layer as a heating means for heat development or dye diffusion transfer. The dye fixing material of the present invention has at least one layer containing the mordant as described above, and when the dye fixing layer is located on the surface, a protective layer can be further provided if necessary. Furthermore, a water absorption layer or a layer containing a dye transfer aid can be provided in order to sufficiently contain a dye transfer aid or to control the dye transfer aid if necessary. These layers may be adjacent to the dye fixing layer or may be applied via an intermediate layer. The dye fixing layer used in the present invention may be composed of two or more layers using mordants having different mordant powers, if necessary. In addition to the above-mentioned layers, the dye fixing material of the present invention may be provided with auxiliary layers such as a release layer, a white reflective layer, a matting agent layer, an anti-curl layer, a neutralization layer, and a neutralization timing layer, if necessary. One or more of the above layers may include a base and/or base precursor to promote dye transfer, a hydrophilic heat solvent, a corrosion inhibitor to prevent color mixing of dyes, a UV absorber, and A vinyl compound, a fluorescent brightener, etc. may be included in the dispersion to increase stability. Silver halides that can be used in the light-sensitive material used in the present invention include silver chloride, silver bromide, silver iodide, silver chlorobromide, silver chloroiodide, silver iodobromide, and silver chloroiodobromide. Either is fine. Specifically, pages 35 to 36 of Japanese Patent Application No. 59-228551,
Any of the silver halide emulsions described in US Pat. No. 4,500,626, column 50, Research Disclosure, June 1978, pages 9-10, etc. can be used. Although the silver halide emulsion may be used unheated, it is usually used after being chemically sensitized. For emulsions for conventional light-sensitive materials, known sulfur sensitization methods, reduction sensitization methods, noble metal sensitization methods, etc. can be used alone or in combination. These chemical sensitizations can also be carried out in the presence of a nitrogen-containing heterocyclic compound (Japanese Patent Application Laid-open No. 1983-1999).
126526, 58-215644). The silver halide emulsion used in the present invention may be of the surface latent image type in which latent images are mainly formed on the grain surfaces, or may be of the internal latent image type in which the latent images are formed inside the grains. Direct reversal emulsions combining internal latent image type emulsions and nucleating agents can also be used. The coating amount of the photosensitive silver halide used in the present invention is in the range of 1 mg to 10 g/m ² in terms of silver. In the present invention, an organic metal salt relatively stable to light can be used in combination with the photosensitive silver halide as an oxidizing agent. In this case, the photosensitive silver halide and the organic metal salt need to be in contact or at a close distance. Such organic metal salts can be used for heat-developable photosensitive materials.
It is effective when developing by heating to a temperature of 60°C or higher, preferably 60°C or higher. Among such organic metal salts, organic silver salts are particularly preferably used.

Another example of the dye-donating substance is a compound that has the function of releasing or diffusing a diffusible dye in an imagewise manner. This type of compound can be represented by the following general formula [L]. (Dye-X)n-Y [L] Dye represents a dye group, a temporarily shortened dye group or a dye precursor group, X represents a simple bond or a connecting group, and Y represents a latent image Corresponding or inversely to the photosensitive silver salt having (Dye-X)n

It is stated in the number etc. In all of these methods, the diffusible dye is released or diffused in areas where no development has occurred, and the dye is neither released nor diffused in areas where development has occurred. Another method is to make the dye-releasing compound into an oxidized form without dye-releasing ability, coexist with a reducing agent or its precursor, and after development, reduce it with the reducing agent that remains unoxidized to produce a diffusible dye. A method for releasing dye has also been devised, and specific examples of dye-donating substances used therein are disclosed in JP-A-53-110827;

Special Publication No. 48-39165, U.S. Patent No. 3443940, etc.
Further, a substance that generates a diffusible dye through the reaction of a coupler having a diffusion-resistant group as a leaving group and an oxidized developer is described in US Pat. No. 3,227,550 and the like. In addition, in systems using these color developers, image contamination due to oxidation and decomposition products of the developer is a serious problem, so in order to improve this problem, we developed a method that does not require a developer and has its own reducing properties. Dye-releasing compounds have also been devised. Representative examples include U.S. Patent No. 3928312, U.S. Patent No. 4053312, U.S. Patent No. 4055428, U.S. Patent No. 4336322, and JP-A-59-65839.

The photographic light-sensitive material and dye-fixing material of the present invention may contain an inorganic or organic hardener in the photographic emulsion layer and other binder layers. Specific examples and specific compound examples can be found in Japanese Patent Application No. 59-268926, pages 94 to 95, and Japanese Patent Application Laid-open No. 59-157636 (3).
Examples include those described on page 8), and these can be used alone or in combination. The support used in the light-sensitive material and dye-fixing material used in the present invention is one that can withstand processing temperatures. As general supports, glass, paper, polymer films, metals, and their analogs are used. You can use what you have. When the light-sensitive material used in the present invention contains a colored dye-donating substance, it is not so necessary to further contain an irradiesin-preventing substance, a halesin-preventing substance, or various dyes. It is possible to contain filter dyes, absorbent substances, etc., which are described in the literature exemplified in Japanese Patent Application No. 59-268926, pages 97-98 and U.S. Pat. No. 4,500,626, column 55 (lines 41-52). . In order to obtain a wide range of colors in the chromaticity diagram using the three primary colors yellow, magenta and cyan, the light-sensitive element used in the present invention comprises at least three layers of silver halide, each sensitive to a different spectral region. It is necessary to have an emulsion layer. A typical combination of at least three light-sensitive silver halide emulsion layers sensitive to different spectral regions is described in JP-A-59-180550. The light-sensitive material used in the present invention may have two or more emulsion layers sensitive to the same spectral region, depending on the sensitivity of the emulsion, if necessary. The photosensitive material used in the present invention may contain various additives known as heat-developable photosensitive materials and layers other than the photosensitive layer, such as an antistatic layer, a conductive layer, a protective layer, an intermediate layer, an AH layers, release layers, matte layers, etc. For various additives, see Research Disclosure Magazine Vol.170,
Additives listed in No. 17029 of June 1978,
Examples include additives such as plasticizers, sharpness improving dyes, AH dyes, sensitizing dyes, matting agents, surfactants, fluorescent whitening agents, and antifading agents. In particular, the protective layer (PC) usually contains an organic or inorganic matting agent to prevent adhesion. Further, this protective layer may contain a mordant, a UV absorber, and the like. Each of the protective layer and the intermediate layer may be composed of two or more layers. In addition, the intermediate layer contains a reducing agent to prevent color mixing.
UV absorbers and white pigments such as TiO ₂ may also be included. A white pigment may be added not only to the intermediate layer but also to the emulsion layer for the purpose of increasing sensitivity. As a light source for image exposure to record an image on a heat-developable photosensitive material, radiation including visible light can be used.
The light sources described in US Pat. No. 4,500,626, column 56, can be used. The heating temperature in the heat development process is approximately 50℃ to approximately 250℃
The heating temperature in the transfer process can range from the temperature in the heat development process to room temperature, but it is particularly useful to develop at a temperature of about 80℃ to about 180℃. More preferably, the temperature is about 10° C. lower than the temperature in the developing step. As a heating means in the development and/or transfer process,
A heating plate, a heat roller, a heating element using carbon, titanium white, etc. can be used. Also, Japanese Patent Application Publication No. 59-218443, Patent Application No. 60-79709
Particularly useful are methods in which development and transfer occur simultaneously or sequentially, as detailed in the US Pat. In this method, the above-mentioned image formation accelerator may be included in advance in either or both of the dye fixing material and the photosensitive material, or may be supplied from the outside. In this method where development and transfer are performed simultaneously or continuously, the heating temperature is 60℃.
As mentioned above, the temperature is preferably below the boiling point of the transfer solvent used as the dye transfer aid. For example, when the transfer solvent is water, the temperature is preferably 60°C or more and 100°C or less. When using a dye-donating substance that releases an image-wise mobile dye in the present invention, a dye transfer aid can be used to transfer the dye from the photosensitive layer to the dye fixing layer. In the method of supplying the dye transfer aid externally, water, caustic soda, caustic potash,
A basic aqueous solution containing an inorganic alkali metal salt and an organic base is used. As these bases, those described in the section of the image formation accelerator can be used. Further, a low boiling point solvent such as methanol, N,N-dimethylformamide, acetone, diisobutyl ketone, or a mixed solution of these low boiling point solvents and water or a basic aqueous solution is used. The dye transfer aid may be used in a manner in which the dye fixing material or the light-sensitive material or both are wetted with the transfer aid. A dye transfer aid (for example, water) is added between the photosensitive layer of a heat-developable photosensitive material and the dye fixing layer of a dye fixing material to promote image transfer. It is also possible to apply a dye transfer aid to one or both of the fixing layers and then superpose them. As a method for applying a dye transfer aid to the photosensitive layer or the dye fixing layer, there is, for example, the method described in Japanese Patent Application No. 59-268926, page 101, line 9 to page 102, line 4. Furthermore, in order to promote dye transfer, a method may be adopted in which a hydrophilic thermal solvent that is solid at room temperature and dissolves at high temperature is incorporated into the light-sensitive material or dye fixing material. The hydrophilic heat solvent may be incorporated into either the photosensitive material or the dye fixing material, or may be incorporated into both. Further, the layer to be incorporated may be an emulsion layer, an intermediate layer, a protective layer, or a dye fixing layer, but it is preferably incorporated in the dye fixing layer and/or a layer adjacent thereto. Examples of hydrophilic heat solvents include ureas, pyridines, amides, sulfonamides, imides, alcohols, oximes, and other heterocycles. The heating means in the transfer process is disclosed in Japanese Patent Application 1983-
There is a means described in No. 268926, page 102, line 14 to page 103, line 11. Alternatively, a layer of an electrically conductive material such as graphite, carbon black, or metal may be applied to the dye-fixing material in an overlapping manner, and an electric current may be passed through this electrically conductive layer to heat it directly. As for the pressure conditions and the method of applying pressure when the heat-developable photosensitive material and the dye-fixing material are superimposed and brought into close contact, the method described on pages 103 to 104 of Japanese Patent Application No. 59-268926 can be applied. After the dye image is transferred, the photosensitive material and the dye fixing material are peeled off to obtain a dye image on the dye fixing material. Specific effects of the invention According to the present invention, since at least a base and/or a base precursor and polyalkylene oxides are contained on the support, precipitation of additives such as a base and a base precursor is prevented. In addition, a dye fixing material is obtained which prevents film deterioration over time and improves adhesion to a photosensitive material during dye diffusion transfer.

These dye fixing materials R-0 to R-3 were stored at 50°C. When we investigated the precipitation of additives such as bases and base precursors on the surface, we obtained the following results. Pigment fixing material No. Additive precipitation R-0 (comparison) Immediately after coating and drying, precipitation was already observed, and a large amount was observed after 1 day at 20% RH.

R-2 (present invention) [same as above R-3 (present invention) When aged for two weeks at a humidity of 20% RH or 70% RH, only a slight amount of precipitation was observed. Next, simultaneous development and transfer processing was performed using these dye fixing materials after storage, and the deterioration of the film was investigated. First, a tungsten light bulb is used in the multilayered color photosensitive material, and a G, R, and IR three-color separation filter (G is 500~
600 nm, R was constructed using a band pass filter of 600 to 700 nm, and IR was constructed using a filter that transmits 700 nm or more), and was exposed to light at 500 lux for 1 second. 20 ml/m ² of water was supplied to the emulsion surface of the exposed light-sensitive material using a wire bar, and the material was overlapped with the dye-fixing materials R-0 to R-3 after storage so that the film surfaces were aligned with each other. Using a heat roller whose temperature was adjusted so that the temperature of the water-absorbed film was 90 to 95°C, the dye fixing material was peeled off from the photosensitive material after heating for 20 seconds. In that case, the dye fixing materials R-1, R- of the present invention

After being left in a room for one month, precipitates appeared on the surface of R-4, but the surface of R-5 of the present invention remained glossy without any precipitates. Processing was carried out in the same manner as in Example 1 using these preserved dye fixing materials and photosensitive material P-2. The dye fixing material R-5 of the present invention gave a good transferred image without peeling.
