<P>PROBLEM TO BE SOLVED: To provide a photosensitive lithographic printing plate material excellent in sensitivity, developability, printing resistance and chemical resistance and ensuring high image performance. <P>SOLUTION: In the photosensitive lithographic printing plate material in which a photoset image is formed by imagewise exposing and photosetting a photopolymerizable photosensitive layer comprising an addition polymerizable ethylenically unsaturated bond-containing monomer (A), a photopolymerization initiator (B) and a polymeric binder (C) on a support and removing the non-image regions from the support with a developer, the polymeric binder (C) is a high molecular material obtained by reacting a high copolymer consisting essentially of a monomer unit (a) having a carboxyl group and high molecular macromolecules interpolymer consist of a monomer unit (b) having a hydroxyl group with a compound (c) having ethylenically unsaturated bond and an isocyanate group which reacts with a hydroxyl group derived from the unit (b) to form a bond. <P>COPYRIGHT: (C)2004,JPO |
