<P>PROBLEM TO BE SOLVED: To provide a negative photosensitive lithographic printing plate developable with a chemical-free developing solution and improved in ink receptivity. <P>SOLUTION: The negative photosensitive lithographic printing plate comprises a photosensitive layer containing a photo-radial generator and a water-soluble polymer, which has a vinyl-substituted phenyl group and is soluble with an aqueous solution having a pH equal to or less than 10, on a support, wherein the photosensitive layer further contains a compound comprising at least two structures expressed by general formula 1. In general formula 1, R<SB>1</SB>represents a hydrogen atom, a halogen atom or an alkyl group; and R<SB>2</SB>represents a hydrogen atom, halogen atom, an alkyl, unsaturated alkyl, aryl, heterocyclic, alkoxy, aryloxy, acyl, amino, hydroxyl, amide, mercapto, sulfo or cyano group. <P>COPYRIGHT: (C)2011,JPO&INPIT |
