Abstract: The present invention relates to a photosensitive relief or intaglio printing plate comprising a base and a photocurable photosensitive layer formed on the base, the photocurable photosensitive layer containing a dye precursor which forms a dye upon irradiation of actinic light. A relief (convex) pattern or a concave pattern can be recognized by coloring, thereby facilitating the printing plate inspecting work. The developing solution used is not colored or contaminated.

Abstract: Constitution: A photosensitive resin composition for printing plates comprising the following components A, B-1, C and D, or a photosensitive resin composition for printing plates, comprising the following components A, B-2, C and D: A: a hydrophilic polymer B-1: a rubber having a molecular weight of 40,00 or more B-2: a dynamically-vulcanized rubber C: a photo-polymerizing unsaturated compound having ethylenic double bond(s) in the molecule D: a photo-polymerization initiator. Advantages: 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.
