Field of the Invention The present invention relates to a lithographic printing plate developing solution utilizing a silver complex salt diffusion transfer method, and in particular, a lithographic printing plate is coated with a developing solution in an amount necessary for development. It is suitable for the method (hereinafter referred to as rapid processing).

Description of the Related Art A lithographic printing plate supplies both water and ink to a plate surface to selectively receive a coloring ink in an image area and water in a non-image area, for example, an ink on the image. Printing is performed by transferring to a printing medium such as paper. Therefore, in order to obtain a good printed matter, the difference in the lipophilicity and hydrophilicity of the surface between the image area and the background non-image area is sufficiently large, and when water and ink are applied, the image area contains a sufficient amount of ink. It is necessary that the non-image area accepts no ink.

作用によってインキ受容性の画像銀として析出する。The exposed silver halide crystals undergo chemical development in the emulsion layer by development processing to become blackened silver, forming hydrophilic non-image areas. On the other hand, the unexposed silver halide crystals are solubilized by the silver complex salt forming agent in the developer, diffused to the physical development nucleus layer on the surface, and the reducing action of the developing agent on the physical development nuclei causes the ink-accepting image silver. Is deposited as.

為には、化学/溶解物理現像との現像時のバランスが重
要になっている。Therefore, a lithographic printing plate using the DTR method undergoes chemical development and dissolution physical development during development processing. In order for the lithographic printing plate to obtain sufficient printing durability as a printing plate, the balance between the chemical / dissolution physical development and the development is important.
【0006】化学現像は速すぎると十分な耐刷力が得ら

処理方法では、現像処理槽、安定処理槽(中和処理槽)
を内蔵した自動製版カメラが用いられている。In the development processing method which has been put into practice for such a lithographic printing plate, a development processing tank and a stabilizing processing tank (neutralization processing tank) are used.
An automatic plate-making camera with a built-in is used.

No. 5549 describes a rapid processing method in which an amount of developing solution necessary for developing a lithographic printing plate is applied and supplied to the plate surface to carry out a plate-making process. In the rapid processing, the developing solution can be developed by always supplying the necessary minimum amount of the developing solution, the developing time can be shortened, and the fatigue of the developing solution becomes irrelevant.

部へ添加剤が浸透しないのである。However, it has been experimentally found that various problems occur when a conventional developing bath type developing solution is applied to the rapid processing system. First, the developing temperature depends on the ambient temperature, and a wide suitable temperature range is required. Second, there is a change in the development speed balance between chemical development and dissolution physical development. That is, dissolution physical development occurs up to the area where chemical development should originally occur. Or vice versa. Thirdly, in the rapid processing method, it was confirmed that the additives, which were conventionally used, do not exert their effects. That is, the additive does not penetrate into the inside of the light-sensitive material.
