PLANOGRAPHIC PRINTING PLATE

摘要

PURPOSE:To provide the planographic printing plate which is formed by using a silver complex salt diffusion transfer method and has excellent ink/water responsiveness and staining resistance. CONSTITUTION:This planographic printing plate is constituted by successively applying one primer layers and silver halide emulsion layers and physical development nuclei on a base. The printing plate contains a matting agent having <=5 micron average particle size in the primer layers and contains latex non- swellable in water in the primer layers. In addition, the total gelatin content on the surface side contg. the silver halide emulsion layers is adjusted to <=5g/m<2>.
