<P>PROBLEM TO BE SOLVED: To provide a lithographic printing plate precursor having developability to an aqueous developer having pH2.0-7.0, and having an antifouling property and printing durability. <P>SOLUTION: This lithographic printing plate precursor contains components (A)-(D) described below, in the lithographic printing plate precursor of removing a photosensitive layer of a non-exposure part, by rubbing a plate face a rubbing member under the presence of the developer of pH 2.0-7.0 by an automatic treating machine provided with the rubbing member, after exposing the lithographic printing plate precursor having at least the photosensitive layer on a support layer. (A): a binder polymer having at least one halogen atom in a side chain, (B): a sensitizer pigment, (C): a polymerization initiator, and (D): a compound having an ethylenic unsaturated bond. <P>COPYRIGHT: (C)2009,JPO&INPIT |
