PURPOSE:To prevent the deterioration of image quality and to enhance the printing resistance of a printing plate by incorporating a silane coupling agent in an interlayer between a substrate and a photoconductive layer to enhance water and solvent resistances of the interlayer. CONSTITUTION:The interlayer formed between the substrate and the photoconductive layer contains 1-15wt% silane coupling agent represented by the general formula: RnSiX4-n in which R is one of 1-30C aliphatic, cycloaliphatic, aromatic, and heterocyclic org. substituents, and at least one of R is a chemically active group, such as vinyl, glycidyl, and mercapto, (n) is 1 or 2, and X is halogen, amino, hydroxy, or the like. A modified silanol compd. produced by hydrolyzing these groups causes a condensation reaction to cross-link synthetic resins and polymers and to give the high resistances to water and solvents. |
