PHOTOSENSITIVE LITHOGRAPHIC PRINTING PLATE MATERIAL

摘要

A photosensitive lithographic printing plate material having a support and, superimposed thereon, a photosensitive layer containing (A) photopolymerization initiator, (B) polymerizable compound having an ethylenic double bond, (C) sensitizing dye and (D) polymer binder, characterized in that the sensitizing dye (C) contains any of compounds of the following general formula (1). The photosensitive lithographic printing plate material is suitable for exposure using laser beams of 350 to 450 nm emission wavelength, exhibiting high sensitivity and excels in storage stability.
