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

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for laser engraving capable of obtaining a flexographic printing plate excellent in an engraved configuration, ink receptivity and printing durability, a flexographic printing original plate for laser engraving using the resin composition for laser engraving, a method for producing a flexographic printing plate using the flexographic printing original plate and a flexographic printing plate obtained by the method for producing the flexographic printing plate.SOLUTION: There is provided a resin composition for laser engraving which comprises: (component A) a macromonomer having only one radically polymerizable group in the molecule; (component B) a polyfunctional ethylenically unsaturated compound having two or more radically polymerizable groups in the molecule; (component C) a binder polymer; and (component D) a radical polymerization initiator.
