PURPOSE:To obtain a photosensitive planographic printing plate having high sensitivity, wide allowance for development, excellent adhesion strength to a supporting body, excellent solvent resistance, and good printing durability by specifying the polymer compd. CONSTITUTION:This photosensitive planographic printing plate has a photosensitive layer consisting of a polymer compd. having the structural unit expressed by formula in the molecule and a photosensitive compsn. containing a quinone diazide compd. as a photosensitive component. This polymer compd. has a copolymer structure of repeating structure with one or more kinds of other vinyl monomers. Other vinyl monomers are p-hydroxy styrene, p- isopropenylphenol, N-(4-hydroxyphenyl)methacrylamide, N-(4-hydroxyphenyl) maleimide, acrylic acid, methacrylic acid, methyl acrylate, ethyl acrylate, methylmethacrylate, ethylmethacrylate, acrylonitrile, etc. |
