Abstract
Planographic master with which a dry planographic printing plate is prepared comprises a substrate and an overlying layer of a photocurable organopolysiloxane composition. The composition comprises (a) an organopolysiloxane having aliphatically unsaturated linkages in the molecule, (b) an mercapto-containing organopolysiloxane, and (c) a photosensitizer. The dry planographic printing plate is prepared by providing imagewise patterns on the organopolysiloxane layer of the planographic master, the organopolysiloxane layer having been cured or being cured by irradiation with ultraviolet light to effect crosslinking by the photochemical addition reaction of the aliphatically unsaturated linkages and the mercapto groups. The printing plates, having ink-receptive image areas and ink-repellent non-image areas, can be used in dry planographic printing, and exhibit quite sufficient printability, especially for office use, to produce satisfactory printed copies.
