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.
