Water-soluble photopolymer composition for flexographic printing and water-soluble photosensitive original printing plate for flexographic printing |
摘要 |
A water-soluble photopolymer composition for flexographic printing is provided which can be water developed and can form a photosensitive original printing plate for flexographic printing having a good flexibility and impact resilience as well as an adequate Shore hardness value. The water-soluble photopolymer composition for flexographic printing contains a water-soluble resin component (A), a photopolymerizable monomer (B) and a photopolymerization initiator (C), in which the water-soluble resin component (A) includes a first partially saponified polyvinyl acetate having a saponification degree ranging from 20 to 70 mole % (A1) and a second partially saponified polyvinyl acetate having a saponification degree ranging from 70 to 95 mole % (A2).
