    摘要: A photosensitive resin composition for printing plates including the following components A, B-1, C and D, or a photosensitive resin composition for printing plates, including the following components A, B-2, C and D:A: a hydrophilic polymerB-1: a rubber having a molecular weight of 40,000 or moreB-2: a dynamically-vulcanized rubberC: a photo-polymerizing unsaturated compound having ethylenic double bond(s) in the moleculeD: a photo-polymerization initiator.The photosensitive resin compositions for printing plates of the invention have high-degree image reproducibility and flexibility suitable for flexography and additionally have good water developability with satisfactory compatibility with aqueous ink. Therefore, using the compositions, flexographic printing plates with excellent printing durability in flexography using aqueous ink or other flexographic printing inks can be produced. Further, using these, water-developable plates for flexography with good rubber elasticity can be produced.
