Field of the Invention The present invention relates to a processing liquid for an offset printing plate using a silver image as an ink accepting property, particularly a direct offset printing plate using a silver complex salt diffusion transfer method. The purpose is to improve the ink receptivity of the formed silver image. More specifically, the offset printing plate is treated by a specific processing agent at an arbitrary stage in the printing process to process the silver image of the offset printing plate formed by the diffusion transfer method to improve the ink receptivity of the silver image itself. Regarding liquid.

For example, Japanese Examined Patent Publication Nos. 48-29723 and 51-157.
No. 62 discloses a technique for improving the ink acceptability of a silver image by treating a silver image formed photographically with a lipophilic agent containing a certain organic mercapto compound. The mercapto compound used for this purpose is an alkaline aqueous solution, or a mixed solution of water with an organic solvent such as alcohol, THF, DMF, or acetone, or is dissolved in a high-boiling point organic solvent in advance to form an oil-in-water dispersion emulsion. Then, it can be added to the treatment liquid.

ってきた。By treating an image with the treatment liquid thus prepared, the ink acceptability of the silver image area is improved as compared with the non-image area, and a function as a printing plate is imparted. However, there are few compounds that improve the ink acceptability of the image area and reduce the background stain in the non-image area, and a compound having a high effect is still required. On the other hand, the demand for printing image quality of printing plates has been increasing in recent years, and there is a strong demand for a processing liquid which allows the image area of the printing plate to quickly and sufficiently receive ink, but which does not cause scumming in the non-image area. It has become like.
