2. Description of the Related Art There have been many attempts as offset printing plates for forming a silver image by a photographic or physical method and using the silver image as ink receptivity.
For example, Japanese Patent Publication No. 48-29723, 51-157
No. 62 discloses a technique for improving the ink receptivity of a silver image by treating a photographically formed silver image with a lipophilic agent containing a certain organic mercapto compound. The mercapto compound used for this purpose is an aqueous alkali solution, or a mixed solution of an organic solvent such as alcohol, THF, DMF, and acetone with water, or dissolved in a high-boiling organic solvent in advance to obtain an oil-in-water dispersion emulsion. Then, it can be added to the processing solution.

By processing an image with the processing solution thus prepared, the ink receptivity of the silver image portion is improved as compared with the non-image portion, and a function as a printing plate is imparted. However, there are few compounds that improve the ink receptivity of an image area and reduce ground smearing in a non-image area, and compounds that are highly effective are still required. On the other hand, the demand for the printing image quality of the printing plate has been increasing in recent years, and there is a strong demand for a processing solution that allows the image portion of the printing plate to quickly and sufficiently receive the ink, but does not cause background staining of the non-image portion. It has become like.
