Title:
A manufacturing method of the photosensitive resin printing plate original edition and a printing plate
Document Type and Number:
Japanese Patent JP6274327
Kind Code:
B2
Abstract:
Disclosed is a resin printing plate precursor comprising at least a substrate and a photosensitive resin layer, the photosensitive resin layer containing: (A) a partially saponified polyvinyl acetate, (B) a polyamide having basic nitrogen, (C) a compound having an ethylenic double bond, and (D) a photopolymerization initiator; the photosensitive resin layer including at least an underlayer and a printing surface layer; the substrate, the underlayer, and the printing surface layer being included in this order; and the photosensitive resin layer containing, as the partially saponified polyvinyl acetate (A), those (A1) having an average polymerization degree of 1,200 to 2,600 in the printing surface layer and those (A2) having an average polymerization degree of 400 to 800 in the underlayer. The present invention provides a photosensitive resin printing plate precursor which has high water developability or rinsing properties for engraving residue, and image reproducibility, and is also excellent in printing durability.
