PHOTOSENSITIVE RESIN COMPOSITION AND RESIN PLATE FOR FLEXOGRAPHIC PRINTING |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a photosensitive resin composition which can form a relief plate for flexographic printing having excellent softness and rebound resilience as well as excellent water proofing property and water swelling resistance, and to provide a resin plate for flexographic printing by using the photosensitive resin composition as a photosensitive resin layer. <P>SOLUTION: The photosensitive resin composition contains the following urethane resin and a photopolymerization initiator. The urethane resin has structural units derived from: (A) a polymer having a carboxyl group and having ≥30 mgKOH/g acid value and <30°C glass transition temperature; (B) a compound having two isocyanate groups in one molecule; (C) a compound having two hydroxyl groups in one molecule; and (D) a photopolymerizable unsaturated monomer having one hydroxyl group or carboxyl group in one molecule. The content of polyether diols in the component (C) is ≤50 wt.%. <P>COPYRIGHT: (C)2004,JPO |
