Abstract: A method of making a waveguide is disclosed. The method comprises providing an optical core having a first surface and a second surface, applying a cladding material to the first and the second surface of the optical core to form a first cladding layer on the first surface of the optical core and a second cladding layer on the second surface of the optical core, and applying a light absorbing composition including a light absorbing material and a first adhesive polymer on at least one of the first cladding layer and the second cladding layer to form a light absorbing layer. The first adhesive polymer is selected from the group consisting of urethane, epoxy, polyester, acrylic adhesives and mixtures thereof.

Abstract: A method for making a panel comprising the steps of providing a plurality of waveguides including an optical core layer having a first and a second surface coated with a cladding material that forms a cladding layer, positioning a thermosetting adhesive between the plurality of waveguides, wherein the thermosetting adhesive includes a thermosetting resin, and curing the thermosetting adhesive.

Abstract: An optical display panel that comprises a plurality of stacked optical waveguides including a plurality of stacked optical waveguides each having an optical core with a first and a second surface, a cladding layer on each of the first and second surfaces of the core, a diffuser on the front face of the stacked waveguides, and a reflector on the back face of the stacked waveguides. The stacked waveguides form a front face and a back face and images are viewed from the front face of the stacked waveguides, which are planar.

Abstract: A ink jet recording medium and, in particular, an ink jet recording medium of photographic quality that in one embodiment exhibits scratch resistance and/or toughness and/or resistance to softening upon printing.
