A method for preparing a lithographic printing plate includes: exposing imagewise a lithographic printing plate precursor comprising, in the following order, a hydrophilic support, a photosensitive layer containing (A) a sensitizing dye, (B) a polymerization initiator, (C) a polymerizable compound and (D) a binder polymer and a protective layer containing at least one acid-modified polyvinyl alcohol in an amount of 50% by weight or more based on a total solid content of the protective layer; and removing the protective layer and an unexposed area of the photosensitive layer with a developer having pH of from 2 to 8. |
