Abstract: Optical films for redirecting light are described, and optical systems, such as display systems, incorporating such optical films are described. The optical film may include a first structured surface including a plurality of prismatic structures, and a second structured surface opposing the first structured surface and including a plurality of microstructures. An effective transmission of the optical film is not more than 1% less than a film with a comparable construction except for a smooth, non-structured second surface.

Abstract: A magnetic film includes one or more magnetically conductive layers. Each magnetically conductive layer is cracked to form a plurality of first through-cracks defining a plurality of magnetically conductive segments. The first through-cracks extend along a first direction and form a first regular pattern along an orthogonal second direction at a first pitch P1, such that a Fourier transform of the first regular pattern has a first peak along the second direction at a first spatial frequency corresponding to the first pitch P1. The first through-cracks have an average length L1 along the first direction. L1/P1 is greater than or equal to 5.

Abstract: The double-sided pressure-sensitive adhesive tape includes a tissue support having a first face and a second face, a first pressure-sensitive adhesive disposed on the first face of the tissue support, and a second pressure-sensitive adhesive disposed on the second face of the tissue support. The first pressure-sensitive adhesive and the second pressure-sensitive adhesive are each crosslinked acrylic-based pressure-sensitive adhesives that are the same or different from each other, and the tissue support is impregnated by the first pressure-sensitive adhesive and the second pressure-sensitive adhesive. The article includes a first substrate and the double-sided pressure-sensitive adhesive tape, in which the first pressure-sensitive adhesive is bonded to a surface of the first substrate.

Abstract: A coil for transfer of information or energy is described. The coil includes an electrically conductive magnetically insulative first layer and a magnetically conductive second layer bonded to the first layer along the length of the first layer. The first and second layers are wound to form a plurality of substantially concentric loops. A width and a length of the second layer may be substantially co-extensive with a respective width and length of the first layer so as to expose opposing longitudinal edge surfaces of the first layer along the length of the first layer. At least one of the opposing longitudinal edge surfaces may include a regular pattern extending substantially along a same first direction and across substantially the entire coil. A method of making the coil is described.

Abstract: Described herein is an article comprising (i) bead film comprising a binder resin layer and a plurality of microspheres partially embedded in the binder resin layer such that a portion of the microspheres outwardly protrude a first distance from the surface of the binder resin layer; (ii) a stabilizing layer disposed on the outwardly protruding microspheres opposite the binder resin layer, wherein the stabilizing layer intimately conforms to the protruding microspheres, and wherein the stabilizing layer has a Tg less than 100 C and a storage modulus at 150° C. of at least 1.5 MPa; and (iii) a release agent, wherein (a) the binder resin layer comprises the release agent, (b) the stabilizing layer comprises the release agent, and/or (c) an intermediate layer comprises the release agent, wherein the intermediate layer is disposed between the monolayer of microspheres and the stabilizing layer, with the proviso that when the binder resin layer has a fluorine content along the polymeric backbone greater than 65 wt %, the stabilizing layer comprises a release agent selected from a silicone and a fluoropolymer. Also disclosed herein are methods of making thermoformable bead films.
