<p>A method for preparing a lithographic printing plate includes: exposing imagewise a lithographic printing plate precursor including a support and an image-recording layer containing (A) a sensitizing dye, (B) a polymerization initiator, (C) a polymerizable compound and (D) a binder polymer; and conducting development processing of the exposed lithographic printing plate precursor with an aqueous solution having pH of from 2.0 to 10.0 to remove an unexposed area of the image-recording layer of the lithographic printing plate precursor, wherein the binder polymer contains as a hydrophilic group, at least one functional group selected from a sulfonic acid group, a salt formed by neutralizing a sulfonic acid, a phosphoric acid group and a salt formed by neutralizing a phosphoric acid, and the aqueous solution contains at least one surfactant containing an aromatic ring and a structure of a salt formed by neutralizing a sulfonic acid.</p> |
