PURPOSE:To prevent peeling of image areas and staining of a background, and to enable a large number of good prints to be made by forming a nonphotosensitive interlayer contg. a silane coupling agent in contact with a support and between the support and a photosensitive layer. CONSTITUTION:A nonphotosensitive interlayer contg. a silane couplng agent is formed in contact with a support and between the support and a photosensitive layer. The surface of the support is treated with a soln. contg. said agent, and the interlayer is formed on it, and the photosensitive layer is formed on the interlayer to obtain a printing plate material. The printing plate thus obtained is good in adhesive strength, and causes no peeling and no staining of the background, and permits formation of a large number of good prints. The silane coupling agent is a compd. obtained by combining at least two kinds of reactive groups and/or an atom directly or by the medium of a linking group, with tetravalent Si, and as the reactive group, an amino, vinyl group, or the like is desirable. |
