RESIN COMPOSITION FOR LASER ENGRAVING, RELIEF PRINTING PLATE ORIGINAL PLATE FOR LASER ENGRAVING AND METHOD FOR MANUFACTURING THE SAME, AND RELIEF PRINTING PLATE, AND METHOD FOR PLATE MAKING OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for laser engraving that can manufacture a relief printing plate that has enough mechanical strength without spoiling an enough coating liquid stability and the reactivity of the radical polymerizable composition after the coating when a radically polymerizable compound and a photothermal conversion medicine are used together as a carbon black and in addition, to provide the relief printing plate original plate that uses the resin composition for the laser engraving and a plate making method of the relief printing plate using the same, and the relief printing plate obtained by the same.;SOLUTION: The resin composition for the laser engraving contains (component A) the carbon black in which the nitrogen adsorption specific surface area is ≥70 m²/g, and the hydroxyl value measured by the Boehm titration is 0-0.03 meq/g, and (component B) the radically polymerizable compound.;COPYRIGHT: (C)2013,JPO&INPIT
