LAMINATES WITH LAYER CONTAINING STYRENE-DIENE BLOCK COPOLYMER FLEXOGRAPHIC PRINTING PLATES

摘要

Laminates for the manufacture of flexographic printing plates and containing a) a layer consisting essentially of a photocrosslinkable mixture of a twoblock copolymer of from 30 to 95% w/w of a diene hydrocarbon and from 5 to 70% w/w of a styrene monomer or a partially hydrogenated product thereof with a compatible monomer having at least one C-C double bond, said mixture containing a photoinitiator, b) a non-photocrosslinkable elastomeric underlayer having a Shore A hardness of from 15 to 70 and c) a non-photo-crosslinkable stabilizing layer preferably between layers a) and b)
