Abstract: This invention relates to a multi-layer element, suitable for the production of printing plates and relief plates, which comprises (a) a photosensitive layer of a mixture which is soluble and/or dispersible in aromatic hydrocarbon solvents or aliphatic halohydrocarbon solvents and consists essentially of at least one elastomeric polymer as the binder, at least one photopolymerizable, ethylenically unsaturated monomer compatible with the binder, and a photopolymerization initiator which is activated by actinic light, with or without conventional additives, (b) a sheet-like polyester shaped article as the dimensionally stable base for the photosensitive layer (a) and (c) a thin adhesive layer, between the layer (a) and base (b), consisting of a thermally hardened mixture which is insoluble in the aromatic hydrocarbon solvents or aliphatic halohydrocarbon solvents and contains (c1) from 90 to 40% by weight, based on the sum of (c1) and (c2), of à resin which has been hardened and crosslinked with isocyanate, and which has from about 4 to 20% by weight, based on the non-crosslinked and hardenable resin, of free OH groups before hardening and crosslinking with isocyanate, and (c2) from 10 to 60% by weight, based on the sum of (c1) and (c2), of an OH-free polycarbonate which is compatible with the resin (c1) before the latter is hardened and crosslinked. The above defined multi-layer element possesses improved stability in processing and use.

Abstract: Photopolymerizable compositions based on an elastomeric styrene-diene block polymer, one or more photopolymerizable olefinically unsaturated monomers and one or more photopolymerization initiators exhibit improved properties if they contain, as an essential constituent, an elastomeric block copolymer of the general structure A-B-C, where A is a thermoplastic, non-elastomeric polymer block based on styrene compounds and having a second order transition point above +25 DEG C., B is an elastomeric polymer block based on butadiene and/or isoprene and having a second order transition point below -20 DEG C. and C is a polymer block, different from B, having a second order transition point of from -30 DEG C. to +15 DEG C., C being either a homopolymer or copolymer block based on butadiene or isoprene or a random copolymer block based on conjugated dienes and styrene compounds. The photopolymerizable compositions may be used, inter alia, for the production of photo-curable adhesives, resilient and flexible sheet material and, in particular, flexographic relief printing plates.

Abstract: The invention relates to relief plates for flexographic printing comprising a relatively soft elastomeric base (U) having a modulus of elasticity of from 10 to 200 kg/cm2 and a thickness of from 0.5 to 6 mm and, firmly bonded thereto, a thin, relatively hard, difficultly soluble intermediate layer Z having a modulus of elasticity of from 1 x 103 to 2.1 x 106 kg/cm2 and a thickness of from 5 to 500 mu and, firmly bonded to said intermediate layer Z, a relief layer P' consisting of a photocrosslinked elastomeric mixture having a modulus of elasticity of from 30 to 2000 kg/cm2 and a thickness of from 200 to 300 mu , the modulus of elasticity of the photocrosslinked relief layer P' being the same as or higher than that of the base U and the neutral surface of the relief plate lying in or near the intermediate layer Z. The invention also relates to photosensitive laminates for the production of such plates.
