Beschreibung
Zusammenfassung:	Disclosed is a block copolymer composition for flexographic printing plates, which is capable of providing a flexographic printing plate that has much more excellent wear resistance than conventional flexographic printing plates, while maintaining sufficient rubber elasticity. The block copolymer composition for flexographic printing plates contains a block copolymer A and a block copolymer B, each of which is an aromatic vinyl-conjugated diene-aromatic vinyl block copolymer having a specific structure. The aromatic vinyl monomer unit content in the block copolymer A is not less than 41%.
