PHOTOSENSITIVE SURFACE PRINTING PLATE MATERIAL

摘要

A photosensitive surface printing plate material, comprising: a substrate; and a photosensitive layer comprising (A) a polymerization initiator, (B) a polymerizable compound having an ethylenic double bond, (C) a sensitizing dye, and (D) polymeric binder, wherein the photosensitive layer contains a sensitizing dye represented by the general formula (1) as the sensitizing dye (C). The material is suitable for the exposure to a laser beam having an emission wavelength ranging from 350 to 450 nm, is highly sensitive, and has excellent storage stability. [General formula (1)]
