Abstract
A planographic dry offset master plate composed of a substrate and, formed thereon, a crosslinking agent-cured layer of a diorganopolysiloxane in which 5 to 40 mole % of the organic groups directly bonded to silicon atoms are phenyl groups. The master plate is especially suitable for plate-making by an electrostatic process and a direct image process. The resulting printing plate has good durability and are free from scumming during printing.
