PURPOSE:To improve image formability and printability by incorporating a polyurethane resin soluble in org. solvents having <=20 deg.C glass transition temp. and film formability as a binder into a photosensitive resin layer. CONSTITUTION:This printing plate is formed by successively laminating the photosensitive resin layer and silicone rubber layer on a substrate. The photosensitive resin layer contains a monomer or oligomer having at least one photopolymerizable or photocrosslinkable olefinic unsatd. double bond group, the polyurethane resin soluble in org. solvents having <=20 deg.C glass transition temp. and the film formability and a photopolymn. initiator. The adhesiveness of the addition type silicone rubber and the photosensitive resin layer is enhanced and the excellent image formability and printability are obtd. |
