<P>PROBLEM TO BE SOLVED: To provide a lithographic printing plate precursor that can be developed even in a pH region from acidic to weak alkaline, has excellent scratch resistance and adhesion resistance even when stacked without using slip sheets, and gives no influence on printing performances, and to provide a stacked of the printing precursors and a method for manufacturing a lithographic printing plate. <P>SOLUTION: The method for manufacturing the lithographic printing plate includes steps of: imagewisely exposing a lithographic printing plate precursor having a photosensitive layer and a protective layer in this order on a hydrophilic support body; and removing the protective layer and the photosensitive layer in an unexposed portion with a developing solution having a pH from 2 to 10. The photosensitive layer contains (A) a sensitized dye, (B) a polymerization initiator, (C) a polymerizable compound and (D) a binder polymer. The outermost layer of the protective layer contains a hydrophilic polymer and organic resin particles containing silica. <P>COPYRIGHT: (C)2009,JPO&INPIT |
