PROBLEM TO BE SOLVED: To provide a photosensitive lithographic printing plate capable of recording an image by laser exposure, having high printing durability, good fine line reproducibility, and suppressed stickiness of a development residual film and a photosensitive layer. In a photosensitive lithographic printing plate in which a photopolymerizable photosensitive layer and an oxygen blocking layer are laminated in this order on an aluminum support, (1) a polyurethane binder, (2 A) a polymerizable compound having a urethane bond and two ethylenically unsaturated bonds, (3) a polymerizable compound having a urethane bond and four or more ethylenically unsaturated bonds, and (4) a photopolymerization initiator. A photosensitive lithographic printing plate characterized by [Selection figure] None |
