    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.

    Abstract: Article comprising a first, microstructured layer comprising a first material, and having first and second opposed major surfaces, the first major surface being a microstructured surface, and the microstructured surface having peaks and valleys, wherein the peaks are microstructural features each having a height defined by the distance between the peak of the respective microstructural feature and an adjacent valley; and a second layer comprising at least one of a crosslinkable or crosslinked composition, wherein at least a portion of the second major surface of the second layer is directly attached to at least a portion of the first major surface of the first, microstructured layer. Articles described herein are useful, for example, for optical film applications. For example. An article including a regular prismatic microstructured pattern can act as a totally internal reflecting film for use as a brightness enchancement film; an article including a corner-cube prismatic microstructured pattern can act as a retroreflecting film or element for use as reflecting film when combined with a back reflector; and an article including a prismatic microstructured pattern can act as an optical turning film or element for use in an optical display.

    Abstract: The present disclosure provides novel light emitting devices including AMOLED displays, based on transparent OLED architecture, where a laminated nanostructured light extraction film can produce axial and integrated optical gains as well as improved angular luminance and color. Generally, the transparent AMOLED displays (100) with laminated sub-micron extractors (110a-c) include: (a) an extractor (110a) on a transparent substrate (112a) for light outcoupling on both sides of the transparent device (120); or (b) an extractor (110b) on a reflective film (112b) for providing light outcoupling off the bottom side of the bottom-emitting (BE) AMOLED (120); or (c) an extractor (110c) on a light absorbing film (112c) for providing outcoupling off the bottom side of the BE AMOLED (120) combined with improved ambient contrast.
