  • Patent number: 6673857
    Abstract: A thermoplastic elastomer composition comprises a) from 5 to 99% by weight of a block copolymer which is composed of hard blocks S made from vinyl aromatic monomers and of one or more random soft blocks B/S made from dienes and from vinyl aromatic monomers, b) from 1 to 95% by weight of a plasticizer with a higher polarity than white oil and with a lower polarity than diisooctyl phthalate, c) from 0 to 50% by weight of a polyolefin, and d) from 0 to 60% by weight of additives, where the total of a) to d) is 100% by weight. The use of the molding compositions to produce flexible or elastic moldings is described, as are the resultant moldings.

  • Patent number: 6326128
    Abstract: A process for the production of a photosensitive recording material for producing relief printing plates is described, in which a photosensitive layer is laminated with a composite element comprising a protective cover sheet, a release layer and, if required, a further layer, wherein the surface of the uppermost layer of the composite element or the surface of the photosensitive layer is subjected to a corona treatment immediately before contact. As a result of the corona treatment, the adhesion of the applied layer is substantially increased.

  • Patent number: 6103451
    Abstract: A multilayer element comprising a substrate, an intermediate layer and a photopolymerizable or photocrosslinkable layer in the stated order is used for producing printing or relief plates. The intermediate layer contains a copolymer of a monomer (A) of the formula (I) or (II) and a copolymerizable monomer (B) ##STR1## where R.sup.1 is vinyl, propen-2-yl, 1-buten-2-yl or styryl or a radical R.sup.2 --O--CO--CH.dbd.CH--, R.sup.2 is an alkyl, aryl, aralkyl or cycloalkyl radical of up to 10 carbon atoms, R.sup.3 is H, methyl or ethyl and n is from zero to 5. The intermediate layer in the multilayer element has improved adhesion in the laminate. It is initially nontacky and does not become tacky until after the application of the photopolymerizable layer, as a result of the interaction with said layer. The improved adhesion in the laminate is retained even after storage and repeated use of the finished printing plates.

  • Patent number: 6037101
    Abstract: A photosensitive recording material having a dimensionally stable substrate and a photosensitive layer which is applied thereon and containsA) an elastomeric block copolymer as a binder,B) a polymerizable compound andC) a compound capable of initiating the polymerization of the compound B under the action of actinic radiation,is described, the elastomeric block copolymer A being a block copolymer having blocks of polymerized1. styrene units,2. alkylene units and3. diene units.The material is suitable for the production of relief printing plates, especially flexographic printing plates, which are distinguished by higher resistance to swelling in the presence of printing inks containing ester solvents or UV-curable components.
