Abstract

A water-developable photosensitive resin printing original plate, includes at least: a support; and a photosensitive resin layer arranged on the support, in which a peripheral side surface of the water-developable photosensitive resin printing original plate is covered with a light-blocking layer; the light-blocking layer contains carbon black and a vinyl polymer at a mass ratio of 80/20 to 30/70; and the vinyl polymer is an alcohol-soluble vinyl polymer containing 25 to 65 mol % of a hydroxyl group with respect to a constituent monomer unit in a molecule (in the case of being chemically modified, a constituent monomer unit after the modification).
