PROBLEM TO BE SOLVED: To obtain a waterless lithographic printing master plate which has good adhesion property with an ink-repelling layer as the upper layer or with a supporting body or a primer layer as the lower layer and which has high polymn. efficiency and excellent storage stability and printing durability, by incorporating a compd. having a specified structure into a photosensitive layer. SOLUTION: This waterless lithographic printing master plate has at least a photosensitive layer and an ink-repelling layer successively formed in this order on a supporting body. The photosensitive layer contains a compd. having a structure expressed by the formula. In the formula, functional groups L may be same or different and are at least one kind selected from hydroxyloglycidyloxy groups, acryloxy groups, methacryloxy groups, 2- hydroxy-3-acryloxypropyloxy groups and 2-hydroxy-3-methacryloxy-propyloxy groups. At least one L is a 2-hydroxy-3-acryloxypropyloxy group and/or 2- hydroxy-3-methacryloxypropyloxy group. |
