  • Patent number: 7989032
    Abstract: A composition comprising a polyanion and a polymer or copolymer of a substituted or unsubstituted thiophene as a solution or as a dispersion in a liquid medium and at least one compound with at least two vinyl groups, wherein said liquid medium comprises at least one non-aqueous solvent and has less than 30% by weight of water; and said composition comprises more than 0.1% by weight of the polymer or copolymer of a substituted or unsubstituted thiophene and is capable of UV-photopolymerization due to said composition comprising at least one vinyl-compound capable of initiating UV-photopolymerization and/or at least one UV-photoinitiator; an ink with the composition of the composition; a process for preparing the composition; a process for producing a layer or pattern on an object with the composition; and a layer, pattern or print produced therewith.

  • Patent number: 5888372
    Abstract: A metal-coated film can be produced continuously from a non-conducting film by successive electroless and galvanic metallization in such a way that a film of this kind is subjected, in a continuous "roll-to-roll" process, to the following operations:a) applying a metallizable primer,b) drying the applied primer,c) conditioning the applied primer,d) optionally activating the applied primer,e) treatment with an electroless chemical metallizing bath,f) optional treatment with a first rinsing liquid,g) treatment with a galvanic metallizing bath,h) treatment with a second rinsing liquid, andi) optional heat treatment of the metallized film.

  • Patent number: 5457018
    Abstract: A shaped article, in particular a support for image information layers prepared from a biaxially stretched film prepared from a polymer blend of 50 to 97 wt.% of a linear polyester and 3 to 50 wt.% of a polymer containing styrene, wherein the percentages relate to the sum of polyester and polymer containing styrene, is characterised by particularly-elevated covering power.
