It concerns the salt diffusion transfer method. (Background of the invention) The silver salt diffusion transfer method (DTR method) is disclosed in U.S. Patent No. 23520.
It is well known as described in No. 14. In the DTR process, II complex salts are imagewise transferred by diffusion from a silver halide agent layer to an image-receiving layer, and they are converted into a silver image, often in the presence of physical development nuclei. For this purpose, an imagewise exposed silver halide emulsion layer is placed in contact with, or brought into contact with, an image-receiving layer in the presence of a developing agent and a silver halide complexing agent, and the unexposed halides are Converts silver to soluble silver complex salt. In the exposed parts of the silver halide emulsion layer, the silver halide is developed to silver (chemical development), so that it cannot be dissolved any further and therefore cannot be diffused. In the unexposed parts of the silver halide emulsion layer, the silver halide is converted to soluble silver salt, which is transferred to the receiver layer,
Therefore, they usually form a silver image in the presence of development nuclei. In direct positive silver halide emulsions, the effects of silver halide in exposed and unexposed areas are reversed. The DTR method has a wide range of applications, including document reproduction, lithographic printing plate production, block material production, and instant photography. The most common diffusion photographic development method for obtaining such transferred silver images involves inserting an image-receiving sheet and an exposed negative sheet into a developer solution in a DTR processor, with the image-receiving layer and photosensitive layer facing each other. A transfer silver image is obtained on an image-receiving sheet by dipping it, squeezing it with a squeeze roller, leaving the required amount of developing solution between both sheets, removing the excess solution, leaving it for a while, and then peeling off both sheets. Met. On the other hand, a method has long been proposed in which only the image-receiving sheet is immersed in a developing solution, and then brought into close contact with an exposed negative sheet outside the developing solution system before being separated (U.S. Pat. No. 317
No. 9517, Special Publication No. 6363893, etc.). However, the latter method had the problem that the amount of processing liquid impregnated into the image receiving sheet was small, resulting in low transfer density (particularly when the image receiving sheet was a film support, the transfer density was low) and low contrast. .. (Problems to be Solved by the Invention) An object of the present invention is to provide a silver salt diffusion transfer method that can obtain high transfer density and contrast. In addition to the above-mentioned objects, the present invention also provides a silver salt diffusion transfer method in which drying of the image-receiving sheet is reduced and staining of the processing solution is reduced. (Means for Solving the Problems) An object of the present invention is to immerse only an image-receiving sheet in a development processing solution, and then, outside the development processing solution system, contact the image-receiving sheet with a negative sheet having an emulsion layer made of silver halide. In the silver salt diffusion transfer method that separates both sheets, 0.9%
This was achieved by containing a super absorbent polymer compound with a water absorption capacity of 40 g/g or more in an aqueous sodium chloride solution. In the present invention, the water absorption capacity, which is a measure of the superabsorbent polymer compound, is 0.9% NaCj! Aqueous solution (25″)
It can be easily determined by immersing 10g of the compound in the liquid and heating it in a constant temperature and humidity chamber at 120''C for 1 hour, then measuring the weight and calculating the amount of water absorbed.The water absorption capacity is 40g/g.
Examples of the above polymer compounds include sodium acrylate polymers and acrylic acid/vinyl alcohol copolymers. Polyethylene oxide derivatives, gelatin, carboxymethyl cellulose, etc. are not effective if their water absorption capacity is less than 30g/g. Preferred examples of such super absorbent polymer compounds include JP-A-52-14689, JP-A-53-50290, and JP-A-5.

温度は25℃である(処理法−1)。A silver salt diffusion transfer negative sheet consists of at least one halide emulsion layer disposed on a support, and generally contains 0.5 to 3.5 g of silver halide in terms of silver nitrate.
/rrr. In addition to this silver halide emulsion layer, necessary auxiliary layers such as an undercoat layer, intermediate layer, protective layer, and release layer are provided. For example, the photosensitive material used in the present invention is disclosed in Japanese Patent Publication No. 3B-18134,
135, etc., such as methyl cellulose, sodium salt of carboxymethyl cellulose, sodium alginate, etc., can be used as a coating layer for the silver halide emulsion layer to ensure uniform transfer. The layer should be thin so as not to substantially prevent or inhibit diffusion. The silver halide emulsion layer of the negative sheet and the image receiving layer of the image receiving sheet both contain hydrophilic colloid substances,
For example, it contains one or more hydrophilic polymer colloid substances such as gelatin, gelatin derivatives such as phthalated gelatin, cellulose derivatives such as carboxymethyl cellulose and hydroxymethyl cellulose, dextrin, soluble starch, and polyvinyl alcohol. Silver halide emulsions consist of silver halides, such as silver chloride, silver bromide, silver chlorobromide, and iodide-containing compounds thereof, dispersed in the above-mentioned hydrophilic colloids. Although general negative-working silver halide photographic emulsions are used in the present invention, direct positive-working silver halide photographic emulsions may also be used. Among direct positive types, those containing an electron acceptor or a halogen acceptor are particularly preferred. The silver halide emulsion used in the present invention may be prepared by any method such as an acid method, a neutral method, or an ammonia method. In particular, a fogged silver halide emulsion containing 50 mole % or more of chloride, as described in U.S. Pat.
Highly sensitive direct positive silver halide emulsions containing water-soluble bromide or bromide and iodide in amounts necessary to increase sensitivity are also preferred. The silver halide emulsion layer and/or the image-receiving layer may contain any compound commonly used for carrying out the silver complex diffusion transfer method. These compounds may include, for example, fog suppressants such as tetrazaindene and mercaptotetrazoles, coating aids such as saponin and polyalkylene oxides, hardeners such as formalin and chromium alum, and plasticizers. Can be done. Known photographic additives can be added to the silver halide photosensitive material (negative sheet) of the present invention. An example is described below.

The precepts can be attained by applying the descriptions in Nos. 63-316853 and 62-23148, etc. The support used for the light-sensitive or image-receiving material is any commonly used support, including paper, film such as cellulose acetate film, polyethylene terephthalate film, etc., a metal support coated on both sides with paper, or a metal support coated on one or both sides with paper. Paper supports coated with alpha-olefin polymers such as polyethylene can also be used. In the present invention, it is preferable to provide an antihalation layer consisting of a carbon black dispersion and/or a dye on the support, and coat the silver halide emulsion layer thereon.
In particular, a developing agent can be added to the coating of the antihalation layer and to the precepts. The developing agents used in the present invention are hydroquinones such as hydroquinone, t-butylhydroquinone, methylhydroquinone, etc., 3-pyrazolidinones such as 1-phenyl-3-virazolidinone, 4,4-dimethyl-1-phenyl-3-virazolidinone, 4-hydroxy Methynole-4-methyl-1-phenyl-3-virazolidinone, 4

In the case of a negative sheet containing a developing agent to be treated with an activator, the developing agent is preferably added to the silver halide emulsion layer and/or its adjacent layer, but it may also be added to the +a layer and/or its adjacent layer. good. In addition to the above-mentioned substances, the processing agents used in the present invention include preservatives such as potassium sulfite and sodium sulfite; antifoggants such as potassium bromide and sodium bromide;
Transfer accelerators such as alkanolamines, viscosity agents such as hydroxyethyl cellulose and carboxymethyl cellulose; surfactants such as polyoxyalkylene compounds and onium compounds; water softeners such as Na salt of EDTA are contained. In addition, the pH of the treated composition is 10.5 to 12, which is 10 to 14, which is required to maintain development activity.
.. 8 is preferred. The silver halide solvent used in the present invention is an alkali metal thiosulfate, such as sodium thiosulfate or potassium thiosulfate, preferably sodium thiosulfate. The halogenated solvent usually ranges from about 0.06 mol/l to about 0.19 mol/l.
It is mole/l. As a color toning agent, for example, imidazolidine-2-thione,
perhydrodiazine-2-thione, mercaptobenzimidazoles (e.g. 2-mercabutobenziξdazole, 2-mercabuto-5-methylbenzimidazole, 2-mercapto-5-chlorobenzimidazole, etc.), mercaptobenzimidazoles ( For example, 2-mercabutoimidazole, 2-mercabuto-4-phenylimidazole, l-methyl-2-mercabuto-5-phenylimidazole, l-benzyl-2-mercaptoimidazole, 2-mercabuto-1-phenylimidazole, etc. )
, mercaptotriazoles (e.g., 3-mercabuto-4.5-dimethyltriazole, 4-p-}ruyl-4H-1.2.4-triazole-3-thiol, etc.), mercaptobenzotriazole [(e.g., penzotriazole) -2-thiol, etc.), tetrazole 5

a-tetrazapentalene, 3,6-diphenyl-1.4
-dimercapto-3H, 6H 32.3a, 5.6a
-tetrazapentalene, etc.) can be used. The color toning agent is preferably about 1.5 x 10-' to about 2 x 10-3 mol per 12 of the processing solution, and 0. IXIO-3~I
X 1 0-3 is particularly preferred. In the silver salt diffusion transfer method, a negative sheet containing a silver halide emulsion layer and an image receiving sheet containing physical development nuclei are generally processed with a processing solution containing a developing agent and a halogenated tRtlj agent. The present invention is also effective in a method in which an image-receiving sheet containing physical development nuclei is processed with a processing solution (activator) containing a silver halide solvent and substantially free of developer. The processing composition has a pH of approximately 10 to 10 for rapid development.
It is usually set at a high alkalinity of 14. For this purpose, alkaline substances such as potassium hydroxide, sodium hydroxide, and phosphates (such as monosodium phosphate) are used. It is sufficient to immerse the image-receiving sheet in a developing treatment solution at an arbitrary temperature for an arbitrary period of time, for example, from several seconds to several tens of seconds.In order to obtain a uniform transferred image on the image-receiving sheet, immersion for at least about 1 second is sufficient. It is preferable to do so. Alternatively, a developing solution may be applied to the image-receiving sheet. Furthermore, when overlapping a negative sheet and an image-receiving sheet containing a developing processing solution outside the system, it is possible to use a simple pair of pressure rollers, but by using a pair of heat rollers, it is possible to eliminate the dependence on processing solution temperature and significantly shorten processing time. Furthermore, it is possible to improve the drying properties of the image-receiving sheet. Since immersion of the image-receiving sheet does not cause any chemical or physical development in the developing solution, it inevitably affects the coloring of the silver sludge by oxides of developing agents such as hydroquinone and virazolidone, as well as the liquid composition. This has the advantage that there is no change in the processing temperature, and the fatigue of the developing solution caused by processing a large number of sheets, or so-called running processing, is extremely low. (Example) Preferred embodiments used in the present invention will be described in detail below. Example 1 An image-receiving layer consisting of gelatin containing metal palladium cores and carboxymethyl cellulose (41) was provided on the side of a 110 g/n paper support coated on both sides with polyethylene so that the dry weight of the hydrophilic colloid was 3 g/nT. An image receiving sheet ■ (paper) was prepared. Next, when forming an image receiving layer, Sumikagel L-5 (H) was used in place of carboxymethyl cellulose to prepare an image receiving sheet ■. On the other hand, on the same paper support as the image-receiving sheet, 0.25 g/rrr of carbon plank, 0.8 glrd of hydroquinone, and 0.2 g/rrf of 4-hydroxymethyl-4-methyl-1-phenyl-3 were added to prevent Halley thinning.
