PROBLEM TO BE SOLVED: To provide a negative type waterless planographic printing plate writable by laser and satisfactory in picture reproducibility and flaw resistance. SOLUTION: In this negative type waterless planographic print, a support body is coated with a photosensitive layer, containing a high-polymer compound including at least one radical chosen between a siloxane radical and an alkyl fluoride radical, and at least one radical chosen between an unsaturated double- bonded radical and a hydroxyl radical, and having adhesion to a silicone rubber layer to be decreased by exposure, and with the silicone rubber layer thereon. |
