    摘要： The invention provides a novel printing plate suitable for use in a dry-process direct planographic printing without the use of a blanket as used in offset printing and without the use of dampening water as in ordinary planographic printing. The printing plate of the invention is constructed with a substrate of which at least the surface layer is made of a rubbery elastomer with an oleophilic or ink-receptive surface and a pattern-wise layer of an ink-repellent material such as a silicone provided on the surface of the substrate to form the non-image areas of the printing plate while the image areas of the printing plate are formed by the oleophilic surface of the substrate exposed bare. By virtue of the rubbery elasticity of the surface layer of the substrate, satisfactorily sharp printed materials are obtained with the inventive printing plate without the use of a blanket as an intermediate carrier of the printing ink.

    摘要： A very simple and easy method for preparing dry planographic printing plates having a high printing performance and durability in the absence of dampening water is proposed. The method comprises the steps of (a) coating one surface of substrate which is transparent to ultraviolet light with an uncured photocurable silicone, (b) bringing the thus coated surface into direct contact with a surface of a base plate to form a laminate, (c) providing on the other surface of the substrate an image pattern made of a material which is opaque to ultraviolet light, (d) irradiating the laminate with ultraviolet light from above the image pattern and (e) separating the substrate from the base plate to allow a portion of the photocured silicone coating to transfer to the surface of the base plate, and a portion of the uncured silicone coating to stay in situ on the surface of the substrate.

    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.

    摘要： The invention provides a novel photocurable organopolysiloxane composition having an unusually high photosensitivity suitable, for example, for providing an anti-sticking layer on a release paper. The composition comprises an organopolysiloxane having, in a molecule, at least one thioacyloxy-containing organosiloxane unit as the photosensitive functional group and a photosensitizer. Further improved photocurable composition of the invention comprises an organopolysiloxane having, in addition to the above mentioned thioacyloxy-containing organosiloxane units, at least one mercaptohydrocarbyl-containing organosiloxane unit in a molecule. Alternatively, photosensitivity of the similar degree is obtained when the composition comprises a first organopolysiloxane having, in a molecule, at least one thioacyloxy-containing organosiloxane unit and a second organopolysiloxane having, in a molecule, at least one mercaptohydrocarbyl-containing organosiloxane unit as combined.
