  • 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.

  • Publication number: 20100314333
    Abstract: The fiber webs described herein may be incorporated into filter media and filter elements. The fiber webs may exhibit a low surface electrical resistivity. The fiber webs may also be sufficiently flexible and/or deformable so that they may be processed to include a series of waves (also known as flutes) that extend along the cross-machine direction.

  • Publication number: 20080286537
    Abstract: An economical method of manufacturing a plastic glazing assembly having a decorative marking and/or opaque border printed from a thermally curable ink is presented. This method includes the steps of forming a substantially transparent plastic panel; printing an opaque pattern from an ink, the printed pattern being in contact with the plastic panel; pre-drying the ink of the printed pattern to a tack-free condition; applying a weather resistant layer on the printed pattern and on the plastic panel; curing the ink of the printed pattern and the weather resistant layer; and depositing an abrasion resistant layer on the weather resistant layer. In this process the drying of the ink substantially removes the solvent from the ink without substantially curing the ink.

  • Publication number: 20070287028
    Abstract: A self-illuminating glazing panel suitable for use in an automotive vehicle is provided for better night and dusk visibility for safety purposes and for brighter appearance during the day. The self-illuminating glazing panel integrates a luminescent layer, containing phosphorescent or fluorescent pigments or dyes, with a plastic substrate. The luminescent layer allows the panel to glow during the evening and night hours upon excitation by external light sources, such as headlamps and streetlights.
