PURPOSE:To obtain a photosensitive resin compsn. having superior workability at a certain high temp., satisfactory shape retentivity as a solid photosensitive resin plate material and superior solvent resistance in the form of a printing plate by incorporating a large amt. of a monofunctional monomer into a compsn. CONSTITUTION:This photosensitive resin compsn. contains 100pts.wt. optionally substd. polyolefin which is solid at 25 deg.C, 100-1,000pts.wt. compd. having one (meth)acryloyl group in one molecule, 0.01-10wt.% photopolymn. initiator based on the total amt. of the compsn. and 0.1-20wt.% gelatinizing agent based on the total amt. of the compsn. The gelatinizing agent is at least one kind of compd. selected among an N-acylamino acid deriv., a compd. having hydroxyl groups and at least one carboxy group in one molecule, a metallic salt of fatty acid and an alkylidenesorbitoal deriv. The photosensitive resin compsn. has superior workability, becomes a solid having satisfactory shape retentivity at room temp. and gives a flexographic printing plate having superior solvent resistance during printing. |
