<P>PROBLEM TO BE SOLVED: To provide a planographic printing plate precursor showing high sensitivity and high plate wear in which developing property and contamination property in a non-image part are improved, and to provide a method for making a planographic printing plate using the precursor. <P>SOLUTION: The planographic printing plate precursor has a support and a photosensitive layer, characterized in that the photosensitive layer contains (A) a polymerizable compound having a specified cyclic structure, (B) a polymerization initiator, (D) a sensitizing dye having a maximum absorption in a wavelength region from 350 to 450 nm, and (E) a binder polymer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
