<P>PROBLEM TO BE SOLVED: To provide a method for producing a lithographic printing plate capable of forming a high-quality image with no stain of a non-image portion, having high strength of a formed image portion, and excellent in printing durability. <P>SOLUTION: In the method for producing the lithographic printing plate, a lithographic printing plate precursor having a recording layer comprising a polymerizable composition comprising a binder polymer containing at least one acid group having an acid dissociation constant (pKa) of ≥5.5 selected from a phenol group which may have a substituent on its aromatic group and a benzenesulfonamide group which may have a substituent on its aromatic group, and a radical addition polymerizable group, a compound capable of generating a radical under light or heat, and a radical polymerizable compound different from the binder polymer is exposed with laser light of ≤450 nm wavelength and developed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
