Original plates for producing dry planographic printing plates comprising (a) a support, and over and in contact with the support, (b) a light-sensitive adhesive layer made of a photopolymerizable composition comprising one or more photopolymerizable ethylenically unsaturated compounds and one or more photopolymerization initiators and overlying said light-sensitive adhesive layer, (c) a light-sensitive ink-repellent layer made of a silicone composition comprising one or more silicones, one or more photopolymerizable ethylenically unsaturated compounds and one or more photopolymerization initiators. Dry planographic printing plates can be produced from the original plates by image-wise exposing to actinic light and developing. |
