PURPOSE:To greatly enhance scratch resistance and solvent resistance of the unexposed part of a silicone rubber layer at the time of developing an original printing plate, and printing resistance of a printing plate by bonding a photosensitive layer to a silicone rubber layer with a specified silicon compd. CONSTITUTION:The photosensitive layer is bonded with the silicone rubber layer by using the silicon compd. represented by formula (I), preferably, formula (II), especially embodied by 3-isocyanate-propyl-trimethoxysilane, etc., in an amt. of 0.05-20wt%, preferably, 0.1-10wt% of the photosensitive layer, and in an amt. of 0.01-10wt%, preferably, in an amt. of 0.1-5wt% of the silicone rubber, when it is added to the rubber. |
