Title:
RESIN COMPOSITION FOR LASER-ENGRAVING, ORIGINAL PLATE FOR LASER-ENGRAVABLE FLEXOGRAPHIC PRINTING PLATE AND METHOD FOR PRODUCING THE SAME, AND PLATEMAKING METHOD FOR FLEXOGRAPHIC PRINTING PLATE
Document Type and Number:
Japanese Patent JP2015123714
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a resin composition for laser-engraving, which can afford a flexographic printing plate excellent in rinsability of engraving scraps, image quality, and ink transferability, and to provide an original plate for a laser-engravable flexographic printing plate.SOLUTION: Provided is a resin composition for laser-engraving, comprising: a component A of a binder polymer having an ethylenic unsaturated bond at least at one portion selected from the group consisting of an inside of a main chain, a terminal of the main chain, and a side chain; a component B of a polymerization initiator; and a component C of a blowing agent. The component A is a plastomer selected from the group consisting of a polymer having a polybutadiene structure, a polymer having a polyisoprene structure, and urethane (meth)acrylate, and a content of the component A is 50 mass% or more relative to a total mass of the composition. Also provided is an original plate for a laser-engravable flexographic printing plate, having a crosslinked relief formation layer obtained by foaming and crosslinking a layer comprising the resin composition for laser-engraving.
