<P>PROBLEM TO BE SOLVED: To provide a negative planographic printing plate original plate wherein the influence of moisture and a salt content deposited on a recording layer surface, in particular, occurrence of image faults in a finger touch region is suppressed. <P>SOLUTION: The negative planographic printing plate original plate has an image recording layer containing a compound (A) decomposed by light or heat to generate an acid, a crosslinking agent (B), a binder polymer (C), an infrared ray absorbent (D), and a copolymer (E) having, as copolymerization components, a monomer expressed by general formula (1) and a monomer having an ethylene oxide chain and a propylene oxide chain. In general formula (1), Rf represents a substituent containing a fluoroalkyl group or perfluoroalkyl group having 9 or more fluorine atoms, and x represents 1 or 2, and R<SP>1</SP>represents a hydrogen atom or a methyl group. <P>COPYRIGHT: (C)2011,JPO&INPIT |
