  • RADIATION-CURABLE COATING COMPOSITION
    Publication number: 20160115322
    Abstract: The present invention relates to a coating composition comprising (a) at least one thermoplastic polymer having a mean molar mass Mw of at least 100 000 g/mol in a content of at least 30% by weight of the solids content of the coating composition, (b) at least one UV-curable reactive diluent in a content of at least 30% by weight of the solids content of the coating composition, (c) at least one photoinitiator in a content of ?0.1 to ?10 parts by weight of the solids content of the coating composition, and (d) at least one organic solvent, where the proportion of ethylenically unsaturated groups is at least 3 mol per kg of the solids content of the coating composition. It further relates to a process for producing such coating compositions, to films coated therewith, to the use of such films for production of shaped bodies, to a process for producing shaped bodies having a radiation-cured coating, and to shaped bodies producible by this process.

  • Silica-containing UV-crosslinkable hardcoat coatings comprising urethane acrylates
    Patent number: 8101673
    Abstract: The present invention relates to a UV-crosslinkable composition comprising a) unmodified, protonated silica nanoparticles; b) urethane acrylate; c) polar solvent; and d) UV initiator system, wherein the amount by weight of unmodified, protonated silica nanoparticles exceeds the content of urethane acrylate and is at least 50.1 wt. %, based on the dry weight of the coating, to the use of the composition in the coating of substrates, and to substrates coated with such formulations.
