RESIN PRINTING ORIGINAL PLATE FOR LASER ENGRAVING

摘要

It is an object of the present invention to provide a resin printing plate precursor for laser engraving that is able to form a relief by laser engraving, the relief having excellent image reproducibility, and moreover has toughness and improved printing durability. The present invention is a resin printing plate precursor for laser engraving comprising a substrate and a resin layer on the substrate, the resin layer containing:
(A) a modified partially saponified polyvinyl acetate having reactive groups in its side chain;
(B) a polyamide having basic nitrogen;
(C) a compound having a 5- to 7-membered ring and a polymerizable ethylenic double bond; and
(D) a photopolymerization initiator.
