RESIN COMPOSITION FOR LASER ENGRAVING, METHOD FOR PRODUCING FLEXOGRAPHIC PRINTING ORIGINAL PLATE FOR LASER ENGRAVING, FLEXOGRAPHIC PRINTING ORIGINAL PLATE, METHOD FOR MAKING FLEXOGRAPHIC PRINTING PLATE, AND FLEXOGRAPHIC PRINTING PLATE

摘要

The purpose of the present invention is to provide: a resin composition for laser engraving, which exhibits excellent rinsing properties with respect to engraving dust that is produced during laser engraving, and which provides a printing plate that has excellent ink resistance to various inks; a flexographic printing original plate which uses this resin composition for laser engraving; a method for producing this flexographic printing original plate; a flexographic printing plate; and a method for making a flexographic printing plate.A resin composition for laser engraving according to the present invention is characterized by containing a thermoplastic elastomer that is obtained by addition polymerization (component (A)), a polymerizable compound (component (B)), and a polymerization initiator (component (C)). This resin composition for laser engraving is also characterized in that the component (A) has a monomer unit having a hydrophilic group and the content of the monomer unit is 1-50% by mole relative to all the monomer units of the component (A).
