<P>PROBLEM TO BE SOLVED: To provide a lithographic printing pate precursor that can efficiently form images using laser exposure without having coagulation precipitation in a protective layer coating liquid although a protective layer includes an inorganic layer compound, and is excellent in plate wear, receptivity and on-press development, and to provide a lithographic printing method using the lithographic printing plate precursor. <P>SOLUTION: The lithographic printing plate precursor includes, on a support: an image recording layer including a polymeric initiator and a radically polymerizable compound; and the protective layer including the inorganic laminar compound. Also the lithographic printing plate precursor includes a specific functional group having ammonium or phosphonium, and a polymer having specific (meth)acrylamide unit in at least the image recording layer or the protective layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
