(Industrial Application Field) The present invention relates to a silver salt lithographic printing material, and more specifically, it not only has excellent photographic properties and less occurrence of scumming, but also has improved ink receptivity and printing durability. The present invention relates to a silver salt lithographic printing material for silver salt diffusion transfer method. (Prior Art) Many types of lithographic printing materials using the silver salt diffusion transfer method have been known.
The most well-known typical type of such material is a lithographic printing material in which a photosensitive photographic element and a physical development nucleus layer, which becomes a printed image element, are integrally constructed. No. 48-
It is described in various publications such as No. 30562. The above-mentioned lithographic printing material has an antihalation layer coated on a support in order from the support side, a hydrophilic colloid layer containing a photosensitive silver halide emulsion as a main component, and a printing element further coated on top of the antihalation layer. After image exposure, a silver salt diffusion transfer process is performed to remove the unexposed silver halide emulsion layer coated on the side closer to the support. The silver halide grains in the above are dissolved by the action of a silver halide complexing agent contained in the processing solution. Then, it diffuses to the physical development nucleus layer coated above the silver halide emulsion layer, accumulates on the physical development nucleus, and is reduced by a developing agent to form a silver image. At the same time, the silver halide in the exposed area becomes blackened silver in the silver halide emulsion layer. In order to apply a silver image obtained by such a diffusion transfer method as a lithographic printing plate, the ink receptivity, ie, lipophilicity, of the silver image area must be high, and the ink repellency, ie, hydrophilicity, of the non-image area must be high. This is very important. That is, it is important that the ink adhesion to the lipophilic image area is excellent and that there is no ink staining to the hydrophilic non-image area. Furthermore, in the case of lithographic printing plates using the silver salt diffusion transfer method, in order to increase the development speed and avoid oxidation of the developing agent in the developer, it has traditionally been done to incorporate a developing agent into the constituent elements. ing. However, when a developing agent is contained in a light-sensitive material, it is unavoidable that the developing agent is oxidized to some extent in the air in the layer, resulting in undesirable phenomena such as deterioration of developability, increased fog, and softening of contrast. It is customary to Sometimes for lithographic printing materials for silver salt diffusion transfer method,
Due to the occurrence of fog due to chemical development of unexposed areas, the amount of silver halide dissolved by the action of the silver halide complexing agent contained in the alkaline activated bath decreases.
A problem arises in that a sufficient lipophilic silver image as a printing plate cannot be formed on the physical development nuclei. By the way, many reports have been made regarding methods for suppressing fog in silver halide emulsions. Typical compounds of fog suppressants used for the purpose of suppressing fog include, for example, 4
-Hydroxy-6-methyl-1,3,3a,7-
Examples include tetrazaindene and 1-phenyl-5-mercaptotetrazole, but printing is also possible using the above-mentioned fog suppressant in a lithographic printing material for diffusion transfer method containing a developing agent in the above-mentioned components. However, if the amount of fog suppressant added is increased in order to obtain a sufficient amount of silver image,
This reduces the hydrophilicity of non-image areas, causing background smearing and softening of tone. Such softening of contrast causes inconvenient phenomena such as the appearance of pasting marks when photographing the original. Also, instead of the above organic fog suppressant,
For example, using potassium bromide alone, an inorganic inhibitor, suppresses fog caused by chemical development, but
At the same time, precipitation of the silver image onto the physical development nuclei is also suppressed. Therefore, there is a strong demand for preventing increase in fog and softening of tone in silver salt lithographic printing materials for use in silver salt diffusion transfer, which contain a developing agent in the constituent elements. (Objective of the invention) The object of the present invention is to provide excellent sensitivity and contrast;
Furthermore, it is an object of the present invention to provide a silver salt lithographic printing material for use in a silver salt diffusion transfer method, which has a high printing durability and is improved in ink receptivity and scumming, and contains a developing agent in a constituent element. (Structure of the Invention) The object of the present invention is to provide a silver salt diffusion layer comprising at least one antihalation layer, a silver halide emulsion layer, and a physical development nucleus layer coated on a support in order from the support side. In the silver salt lithographic printing material for the transfer method, an amount of a developing agent and a compound represented by the following general formula [] or [] to enable development of the silver halide exposed in the constituent elements in an alkaline activation bath. This can be achieved by using a silver salt lithographic printing material containing at least one type of silver salt. General formula []

After dispersing, they were sequentially mixed, and then liquid d was added to prepare a final coating liquid. After coating the above coating solution as a layer, a photosensitive silver halide emulsion prepared as described below was coated on this layer. The above-mentioned photosensitive silver halide emulsion is a silver chloride emulsion prepared by the usual double-jet method, chemically sensitized with a sulfur sensitizer, and after optical sensitization (ortho sensitization), 4-hydroxy-6 is used as a stabilizer. After adding an appropriate amount of -methyl-1,3,3a,7-tetrazaindene, the exemplary compound according to the present invention and the following comparative compounds (A) and (B) were added as shown in Table 1, respectively. Subsequently, an appropriate amount of isoamyl-n-decylsulfosuccinic acid sodium salt was added as a coating aid to prepare an emulsion coating solution. The amount of silver coated is 0.8 in terms of silver.

It was used as a stock solution for finishing physical development nuclei. An appropriate amount of saponin was added as a coating aid to this gold colloid solution to prepare a coating solution, which was coated at an amount of 2.5 mg/m 2 of gold. The resulting printing material was exposed with a sensitometer through a light wedge and statically developed. In addition, an automatic plate making machine (12.18 manufactured by ITETSUKU Co., Ltd.) is used to perform image exposure, development,
Stabilization treatment was performed. The composition of the treatment liquid used is as follows. (Alkaline activation bath for development) Anhydrous sodium sulfite 50g Potassium hydroxide 25g Sodium thiosulfate 3.0g Add water to make 1 (Stabilizing bath) Sodium citrate 10g Citric 1.0g Ethylene glycol 10g Add water to make 1 Next, the printing plates processed by the automatic plate making machine were printed using an offset printing machine (Gestettner 200, manufactured by Gestettner), and the results obtained are shown in Table 1 below. The print evaluation in the table was determined by the following method. Ink receptivity: Evaluated by the number of prints until good prints with high print density are obtained from the time when the ink roller and plate surface are brought into contact and paper feeding is started.○: Obtained within 10 sheets. △: Obtained within 30 sheets. ×: Prints with high density cannot be obtained even after 50 sheets or more. Ground stains: Evaluated by the density of background stains in the white area of the 500th printed page. ○: No stains occur on the ground. △: Thin dirt is partially generated. ×: High concentration of dirt on the entire surface. Printing durability: Evaluated by the number of prints printed continuously that become defective due to a decrease in ink density, blurred images, smudges, etc. ○: Good even after 5,000 sheets or more △: Failure occurs between 3,000 and 4,000 sheets ×: Failure occurs after 3,000 sheets Damping test Performed 500 revolutions of dry running with only the dampening liquid supplied onto the plate surface. Later, when printing was started after contacting the ink for the first time, a test was conducted to determine how many good prints were obtained.The lower the number, the less fading (defective prints), and it can be said that the printing plate has a long printing life. .
