  • Plastic glazing panel having UV curable printed pattern and process for making the same
    Patent number: 8361601
    Abstract: An economical method of manufacturing a plastic glazing panel having a decorative marking and/or opaque border printed from a UV curable ink is presented. This economical method includes the steps of forming a plastic panel; printing an opaque pattern from an ink, the pattern having an A-side and a B-side with the B-side being in contact with the plastic panel; curing the ink in the shape of the printed pattern using UV radiation directed at the ink from both the A-side and B-side; applying a weatherable layer on the A side of the pattern and on the plastic panel; curing the weatherable layer; and depositing an abrasion resistant layer onto the weatherable layer.

  • Inks for in-mould decoration
    Patent number: 7763670
    Abstract: An energy-core ink or varnish composition is provided for use in an in-mold decoration (IMD) process, comprising an energy-curable resin, additional reactive monomers and/or oligomers and, optionally and in an amount not exceeding 10% by weight, a solvent, wherein the resin comprises a urethane acrylate oligomer having an aromatic or aliphatic polycarbonate backbone. For inks, the composition additionally includes a pigment or dye. For photocure compositions, a photoinitiator is also included. Also provided is an in-mold decoration (IMD) process employing the ink or varnish composition.
