PURPOSE:To obtain the photosensitive planographic printing plate which has an excellent sensitivity, image reproducibility, chemical resistance and printing resistance and has the excellent characteristics to prevent the generation of stains in non-image pattern parts. CONSTITUTION:This photosensitive planographic printing plate has a photosensitive layer on a base and has a layer contg. at least either of a silane coupling agent and a group consisting of the alkaline metal salt of silicic acid, the alkaline metal salt of hexametaphosphoric acid or polyvalent carboxylic acid between the base and the photosensitive layer. |
