Title: PHOTOSENSITIVE RESIN COMPOSITION AND PHOTOSENSITIVE RESIN PLATE PRECURSOR
Abstract:
The present invention provides a photosensitive resin composition that contains a resin (A) having an ionic functional group, a photopolymerization initiator (B), a photopolymerizable monomer (C), and a fluorine-containing compound (D) having an ionic functional group capable of forming counterions with the resin (A). By virtue of the present invention, it is possible to economically provide a photosensitive resin letterpress plate capable of maintaining the antifouling plate surface even during a printing step and a post-printing plate washing step without adding operations to the conventional plate making step, thereby providing a plate capable of significantly reducing printing defects caused by halftone mottle.
