Abstract
The planographic printing plate has ink-receptive and ink-repellent areas provided on its base, the ink-repellent areas being covered with a layer formed by polymerizing and curing a composition which comprise a photopolymerizable organopolysiloxane with maleimido groups. The photopolymerizable organopolysiloxane has easily synthesized. The ink-repellency of the cured organopolysiloxane is excellent. The planographic printing plates can be used without dampening water and have a superior press life.
