PHOTOSENSITIVE COMPOSITION, PHOTOSENSITIVE LITHOGRAPHIC PRINTING PLATE MATERIAL, AND METHOD FOR IMAGE FORMATION OF LITHOGRAPHIC PRINTING PLATE MATERIAL

摘要

This invention provides a photosensitive lithographic printing plate material, which has excellent antifouling properties and storage ability, a photosensitive composition for constituting the photosensitive lithographic printing plate material, and a method for image formation of a lithographic printing plate material using the photosensitive lithographic printing plate material. The photosensitive composition comprises (A) an addition polymerizable ethylenical double bond-containing compound, (B) a photopolymerization initiator, and (C) a polymeric binder and is characterized in that the photopolymerization initiator (B) is an iron arene complex compound and the photosensitive composition further comprises a siloxane glycol copolymer.
