<P>PROBLEM TO BE SOLVED: To provide a photosensitive resin composition which is sensitive to light in a near infrared region, can draw a picture directly on a plate with a laser beam, requires neither development nor wiping-off operation, is used for a lithographic printing plate of using dampening water in printing and excellent in hydrophilic property and plate wear, and to provide the lithographic printing plate for which the photosensitive resin composition is used. <P>SOLUTION: The photosensitive resin composition for lithographic printing comprises a hydrophilic resin, a cross linking agent, a hydrophobic resin and a light absorbing agent. The hydrophilic resin is 100-30,000 centipoise in Brookfield viscosity at 25°C of 15 wt.% aqueous solution and ≥200,000 in weight average molecular weight. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
