一般式〔〕
(Industrial Application Field) The present invention relates to a method for producing a lithographic printing plate, and more specifically, a direct lithographic plate in which a silver image obtained by a silver salt diffusion transfer method is made receptive to lipophilic ink. The present invention relates to a method for producing printing materials. (Prior art) Many methods have been known for offset printing plates using the silver salt diffusion transfer method, and representative ones include U.S. Pat.
Methods described in various specifications of No. 3161508, Japanese Patent Publication No. 1672-1980, and the like are known. Also, special public service in 1977-
There are also methods described in publications such as No. 42453 and No. 48-30562. The former method uses a printing plate in which the photosensitive element and the development nucleus layer, which is a printed image element, are each made up of separate units, whereas the latter method uses
This is a technology related to printing plates that is integrated with this technology. As yet another method, US Pat. No. 3,511,656
There is a method described in the specifications of No. 3557690, No. 3557690, etc., and this method involves diffusion transferring the photosensitive element provided in the top layer to the printing image element in the lower layer, and then leaching and peeling off the top layer with water for printing. It's something you get a version of. In order to apply a silver image obtained by such a diffusion transfer method as an offset printing plate, the ink receptivity, ie, hydrophobicity, of the silver image area must be high, and the ink repulsion, ie, hydrophilicity, of the non-image area must be high. This is very important. Many techniques have been proposed to improve the ink receptivity or printing durability, such as methods of improving the printing plate itself or methods of improving the processing method of the printing plate. In a lithographic printing plate that utilizes a silver salt diffusion transfer method and has an integrated structure as described above, for example, after image exposure, a silver halide coating near the support is carried out by a silver salt diffusion transfer process. The silver halide grains in the unexposed areas of the emulsion layer are dissolved by the action of the 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. The state of the silver image on the physical development nuclei formed in this way has a great influence on ink receptivity and printing durability, but this is due to the silver content of the silver halide complexing agent contained in the transfer developer. It depends on the diffusion rate and stability of the complex salt. Examples of silver halide complexing agents in the above diffusion transfer developer include thiosulfates, thiocyanates,
Amine thiosyl phaate anhydride described in US Pat. No. 3,169,992, cyclic imide described in US Pat. No. 2,857,276, and the like are known. However, printing plates subjected to transfer and development treatment using these silver halide complexing agents do not have satisfactory printing durability. In addition, printing plates are usually subjected to a diffusion transfer process after being photographed using an automatic developing machine with a built-in transport roller. It has the disadvantage that it changes. (Objective of the Invention) The first object of the present invention is to provide a method for producing a lithographic printing plate which is excellent in printing durability and ink receptivity, and has excellent printing characteristics without soiling. A second object of the present invention is to provide a method for producing a stable lithographic printing plate in which the ink receptivity of a silver image formed does not change due to differences in stirring conditions of a transfer developer during diffusion transfer processing. be. (Structure of the Invention) The object of the present invention is to provide at least one compound having a ring structure represented by the following general formula [], [] or [] in a method for producing a lithographic printing plate using a silver salt diffusion transfer method. This can be achieved by a method for producing a lithographic printing plate in which an image is formed in the presence of seeds. General formula []
