Abstract
A support is laminated with a light-sensitive layer and a silicone rubber layer in this order, wherein the light sensitive layer comprises (a) a resol resin, (b) a novolak resin, (c) an infrared absorber, and (d) a compound which generates an acid with heat, thereby providing a light-sensitive lithographic printing plate requiring no fountain solution for direct print-making, which can directly record digital date of computers, etc. with solid lasers or semiconductor lasers having light emitting regions from near infrared to infrared.
