<P>PROBLEM TO BE SOLVED: To provide a polymerizable lithographic printing plate which has high temporal stability, high sensitivity and excellent plate wear and contamination property owing to firm adhesion strength between a photosensitive layer and a supporting body, which is free from thin lines or missing of a highlight part even when printing is carried out in a great amount, and which makes direct laser writing possible. <P>SOLUTION: The printing plate has a polymerizable photosensitive layer having the following components (A) to (D) on a supporting body having a hydrophilic surface, with ≥0.2 difference in I/O (inorganic substances/organic substances) between (A) and (B). The components are: (A) a first alkali-soluble binder having an ethylenically unsaturated double bond; (B) a second alkali-soluble binder; (C) a monomer having an ethylenically unsaturated double bond; and (D) a polymerization initiator. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
