    摘要： The invention provides a novel method for the preparation of a printing plate suitable for dry planographic printing without supply of dampening water utilizing the ink-repellency of a cured silicone resin. In the inventive method, a base plate provided with two successive layers of a first adhesive agent and a photocurable organopolysiloxane composition is overlaid with a UV-transparent covering sheet provided with a layer of a second adhesive agent in such a manner that the layers of the organopolysiloxane composition and the second adhesive agent are in direct contact with each other and irradiated with UV light pattern-wise through the sheet. The adhesive bonding strength between the second adhesive agent and the organopolysiloxane composition exhibited by the exposure to light is larger than between the first adhesive agent and the organopolysiloxane composition so that peeling of the covering sheet off the base plate leaves the layer of the organopolysiloxane composition pattern-wise in the unirradiated areas, which is subsequently photocured by the second exposure to light to give image-wise ink-repellent areas formed of the cured organopolysiloxane composition bonded to the base plate useful as a planographic printing plate of high durability.
