Title: RESIN COMPOSITION FOR LASER ENGRAVING, FLEXOGRAPHIC PRINTING ORIGINAL PLATE FOR LASER ENGRAVING, METHOD FOR PRODUCING FLEXOGRAPHIC PRINTING ORIGINAL PLATE FOR LASER ENGRAVING, FLEXOGRAPHIC PRINTING PLATE, AND PLATE MAKING METHOD FOR FLEXOGRAPHIC PRINTING PLATE
Abstract:
The present invention addresses the problem of providing: a resin composition for laser engraving, which is capable of providing a flexographic printing plate that exhibits excellent sheet processability, ink resistance and printing durability; a flexographic printing original plate for laser engraving, which uses this resin composition for laser engraving; a method for producing this flexographic printing original plate for laser engraving; a plate making method for a flexographic printing plate, which uses this flexographic printing original plate; and a flexographic printing plate which is obtained by this plate making method. A resin composition for laser engraving according to the present invention is characterized by containing a polymer that has a monomer unit derived from a conjugated diene hydrocarbon (component (A)) and a transpolyisoprene and/or a polyoctenylene (component (B)) in an amount of 1 part by mass or more per 100 parts by mass of the component (A). This resin composition for laser engraving is also characterized in that the component (A) and the component (B) are different polymers.
