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 engra ving type flexographic printing plate mold having excellent engraving dust rinsability and dispersion suppre ssion 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 carb oxy group and a constituent unit derived from an isocyanate compound; an ethylenically unsaturated compound (component B); and a polymerization initiator (component C).
