Abstract: Processing tapes for use in preparing optical articles include a thermally stable tape backing and a low tack adhesive layer at least partially coated on tape backing. The low tack adhesive layer includes a crosslinked, polyester-containing (meth)acrylate-based polymer that is essentially free of volatile components, is unchanged after heat aging of 150 C for 1 hour under a pressure of 4.31 kiloPascals, and is able to removably adhere to the anti-reflective, nanostructured surface coating of an optical construction.

Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packet pairs. Some polymer layers, including at least one embedded layer, may include an ultraviolet (UV) light stabilizer such as a UV absorber, antioxidant, or hindered amine light stabilizer (HALS), and these layers may be positioned at the front of each layer packet. After the UV-stabilized layer of one packet has been used, the packet can be peeled away to expose a new UV-stabilized layer of the next layer packet.

The transfer films (100) may include a plurality of co-extensive electrical protolayers (22, 23, 24) forming an electrical protolayer stack (20), at least selected or each electrical protolayer independently comprising at least 25 wt % sacrificial material and a thermally stable material and having a uniform thickness of less than 25 micrometers. The transfer films may include a plurality of co-extensive electrical protolayers forming an electrical protolayer stack, at least selected or each protolayer independently exhibiting a complex viscosity of between 103 and 104 Poise at a shear rate of 100/s when heated to a temperature between its Tg and Tdec.

Abstract: The present application generally relates to retroreflective articles and methods of making retroreflective articles. The retroreflective articles include a substantially amorphous polymeric layer between the body layer and the discrete truncated cube corner elements. The substantially amorphous polymeric layer absorbs, dissipates, and/or accommodates at least some of the stress forces placed on the retroreflective article during processing. As a result, discrete truncated cube corner elements with increased fidelity can be formed. Consequently, retroreflective sheeting including a substantially amorphous polymeric layer has increased brightness compared to similarly made and composed sheeting lacking the substantially amorphous polymeric layer.

Abstract: A multilayer optical film (130) has a packet of microlayers that selectively reflect light by constructive or destructive interference to provide a first reflective characteristic. At least some of the microlayers are birefringent. A stabilizing layer attaches to and covers the microlayer packet proximate an outer exposed surface of the film Heating elements (122) can physically contact the film to deliver heat to the packet through the stabilizing layer by thermal conduction, at altered regions of the film, such that the first reflective characteristic changes to an altered reflective characteristic in the altered regions to pattern the film The stabilizing layer provides sufficient heat conduction to allow heat from the heating elements to change (e.g. reduce) the birefringence of the birefringent microlayers disposed near the outer exposed surface in the altered regions, while providing sufficient mechanical support to avoid substantial layer distortion of the microlayers near the outer exposed surface in the altered regions.
