Photosensitive resin composition

A photosensitive resin plate for flexoprinting comprising a substrate and a layer of a photosensitive resin composition formed thereon, wherein said photosensitive resin composition comprises

• (A) 25 to 80% by weight of crosslinked polymer particles having a particle size of 0.01 to 5 micron, prepared from an aliphatic conjugated diene monomer, a monofunctional monomer and a polyfunctional monomer,
• (B) 10 to 70% by weight of a hydrophobic elastomer having a molecular weight of 5,000 to 1,000,000 and at least one glass transition temperature of 5.degree. C. or less, prepared from at least 30 mol % of a conjugated diene monomer and the balance of other monomers,
• (C) 1 to 25% by weight of a hydrophilic polymer having a molecular weight of 1,000 to 1,000,000, prepared by introducing hydrophilic groups into a backbone polymer selected from the group consisting of (1) a polymer obtained from a conjugated diene, (2) a copolymer of a conjugated diene and a monoolefinic unsaturated compound, and (3) a vinyl polymer other than the polymer (1) and the copolymer (2),
• (D) 1 to 30% by weight of a basic nitrogen-containing compound,
• (E) 1 to 60% by weight of a photopolymerizable ethylenically unsaturated monomer, and
• (F) 0.01 to 10% by weight of a photopolymerization initiator;
• % by weight being based on a total amount of the resin composition.
