RESIN COMPOSITION FOR LASER ENGRAVING, FLEXO PRINTING PLATE MASTER FOR LASER ENGRAVING AND METHOD FOR MANUFACTURING THE SAME, AND FLEXO PRINTING PLATE AND PLATEMAKING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for laser engraving having a high engraving sensitivity and capable of inhibiting the quantity of engraving debris and of yielding a flexo printing plate having a favorable engraving debris rinsability; a flexo printing plate master using the resin composition for laser engraving and a method for manufacturing the same; a platemaking method of a flexo printing plate using the same; and the flexo printing plate thus obtained.SOLUTION: The provided resin composition for laser engraving includes a binder polymer (component A) and a crosslinking agent (component B), where a crosslinked relief formation layer formed from the composition is depolymerizable.
