PURPOSE: To provide a photosensitive flexographic printing plate having an improved mechanical strength without deteriorating the reproducibility of relief image. CONSTITUTION: This compsn. contains fine resin particles of about 0.01-6μm average particle diameter made of an internally crosslinked homo- or copolymer of monomer having a polymerizable ethylenically unsatd. group, a resin having rubber elasticity, a photopolymerizable ethylenically unsatd. monomer, a photopolymn. initiator, a polymn. inhibitor, a photosensitizer and a plasticizer. This compsn. has 30-80 deg.C JIS A hardness and at least 20% impact resilience after curing by irradiation with light. |
