Abstract
The invention involves a photosensitive composition and a printing element made from the photosensitive composition as well as a method of making the printing element. The photosensitive composition is made from a blend of a crosslinking photoinitiator with an asymmetric, multi-branched, block copolymer containing (a) a polymer block A having at least predominantly a polymerized alkenyl arene block, (b) a polymer block B having at least predominantly a polymerized conjugated diene block, (c) a polymer block C having at least predominantly a polymerized conjugated diene block, and (d) the residue of a multifunctional coupling agent. Block A and block B form the structure A-B and the multifunctional coupling agent is between at least one block C and the block B of at least one A-B. The photosensitive composition may optionally include an ethylenically unsaturated crosslinking agent.
