PHOTOSENSITIVE RESIN COMPOSITION FOR PRINTING AND RESIN PLATE USING THE COMPOSITION

摘要

PURPOSE: A photosensitive resin composition and a photosensitive resin printing plate which is coated with the composition are provided to obtain excellent flexibility and repulsion property and to maintain properties of the printing plate at a high temperature and high humidity. CONSTITUTION: A photosensitive resin(11) composition for a printing plate comprises: urethane acrylate oligomer 4~10 parts by weight; thermoplastic polyurethane 10~20 parts by weight which has a glass transition temperature more than 35°C; urethane polymer 60~70 parts by weight; photopolymerizable monomer 10~20 parts by weight having one or more acroyl group or methacroyl group; photopolymerization initiator 1~5 parts by weight which is selected from acetophenone or benzyl ketal compound; silicon or fluorine-based leveling agent 0.1~0.4 A parts by weight; and silicon or non-silicon-based antifoaming agent 0.1~0.4 parts by weight.
