<P>PROBLEM TO BE SOLVED: To provide a photosensitive lithographic printing plate on which an image is recorded by laser exposure, which ensures high printing durability and good thin line reproducibility, and reduces a residual film after development and the stickiness of a photosensitive layer. <P>SOLUTION: The photosensitive lithographic printing plate is obtained by stacking a photopolymerizable photosensitive layer and an oxygen intercepting layer in this order on an aluminum support, wherein the photosensitive lithographic printing plate contains, in the photopolymerizable photosensitive layer, (1) a polyurethane binder, (2) 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 polymerization initiator. <P>COPYRIGHT: (C)2007,JPO&INPIT |
