Photosensitive element for flexographic printing

A photosensitive element for flexographic printing comprising (a) a support layer;

• (b) a photosensitive resin layer which comprises, as a binder polymer, a thermoplastic elastomer obtained by polymerization of a monovinyl-substituted aromatic hydrocarbon and a conjugated diene, said photosensitive resin layer (b) is on the support layer (a);
• and (c) a non-infrared ray-shielding layer which can be ablated with an infrared laser, and comprises a binder polymer, an infrared absorber and a non-infrared ray-shielding material, said non-infrared ray-shielding layer (c) is directly on the photosensitive resin layer (b),
• wherein the photosensitive resin layer (b) further comprises, at least one ethylenically unsaturated monomer capable of being radically polymerized and a photopolymerization initiator;
• and
• wherein the binder polymer of the non-infrared ray-shielding layer (c) is a styrene-conjugated diene copolymer having a styrene content of 60 to 90% by weight or a hydrogenation product of a styrene-conjugated diene copolymer having a styrene content of 10 to 50% by weight.
