PURPOSE:To provide the printing plate without the adhesive strength of a silicone rubber layer to a photosensitive layer being affected by the amt. of moisture in the atmosphere when the rubber layer is cured and having higher water repellency than before. CONSTITUTION:A lithographic printing plate consisting of a substrate, a photosensitive layer on the substrate and a silicone rubber layer provided on the photosensitive layer is produced as follows. Namely, a photosensitive layer is formed on a substrate, and then a silicone composition obtained by the addition reaction between a compd. having >=2 hydrogen-silicon bonds in one molecule and a compd. having >=2 carbon-carbon unsaturated bonds in one molecule is applied on the photosensitive layer. |
