RESIN COMPOSITION FOR LASER ENGRAVING, LASER ENGRAVING-TYPE FLEXOGRAPHIC PRINTING PLATE MOLD AND PRODUCTION METHOD THEREFOR, AND FLEXOGRAPHIC PRINTING PLATE AND PLATE-MAKING METHOD THEREFOR

摘要

The purpose of the present invention is to provide a resin composition for laser engraving capable of obtaining a laser engraving-type flexographic printing plate mold having excellent engraving dust rinsability and dispersion suppression properties, a laser engraving-type flexographic printing plate mold using said resin composition for laser engraving and a production method therefor, and a flexographic printing plate and a plate-making method therefor. This resin composition for laser engraving is characterized by containing: a polyurethane resin (component A) having a constituent unit derived from a polymer polyol compound having a carboxy group, and a constituent unit derived from an isocyanate compound; an ethylenically unsaturated compound (component B); and a polymerization initiator (component C).
