Abstract: The present disclosure provides a coated microstructured film (100a-c). The coated film includes microstructures (110) extending across a first surface of the microstructured film (100a-e) and a coating (130) on a first portion of at least some of the microstructures (110). The coating (130) includes one or more polyelectrolytes and has an average thickness T. A second portion of the coated microstructures either lacks the coating or has the coating with an average thickness of no more than 50% of T. The coating (130) is essentially free of any light absorptive material. A method of making the coated microstructured film (100a-c) is also provided. The method includes obtaining a microstructured film (100a), applying a coating (130) containing one or more polyelectrolytes to at least some of the microstructures (110), and removing at least some of the coating (130) from a second portion of the coated microstructures. Additionally, the present disclosure provides a method of making a light control film (110d. 100e). The method includes the above method as well as either infusing a light absorptive material into the coating of the coated microstructured film (100b-d) or applying a layer of a pigment on the coating. Such a light control film exhibits a transmission of visible light of 75% or greater at a viewing angle of 0 degrees.

Abstract: A transfer article (100) comprising a substrate (110), a first acrylate layer (120) overlaying the substrate layer (110), a release layer (130) overlaying the first acrylate layer (120), a second acrylate layer (140) overlaying the release layer (130), and a function layer (150) overlaying the second acrylate layer (140). The release layer (130) comprises a metal layer or a doped semiconductor layer. The function layer (150) may be applied to a surface of a receiving article (170) and the release layer (130) removed from the receiving article (170) such that the function layer (150) and second acrylate layer (140) remain on the surface of the receiving article (170).

Abstract: Ultraviolet light shielding articles are provided. An ultraviolet light shielding article includes a flexible substrate having a major surface and a multilayer optical film disposed on the major surface of the substrate. The multilayer optical film is comprised of at least a plurality of alternating first and second inorganic optical layers collectively reflecting and absorbing at an incident light angle of at least one of 0°, 15°, 30°, 45°, 60°, or 75°, an average of at least 50, 60, 70, 80, 90, or 95 percent of incident ultraviolet light over at least a 30-nanometer wavelength reflection bandwidth in a wavelength range from 190 nanometers (nm) to 400 nm. Solar cell covers including an ultraviolet shielding articles are also provided.

Abstract: A nose foam for a respiratory protection device is presented that includes a first check portion, a second check portion, and a nose bridge portion. The first and second check portions are both wider than the nose bridge portion. The nose foam is selected for the respiratory protection device by a computer-based respiratory protection device selection system, based on a facial feature of a wearer.

Abstract: A light control film comprises a light input surface and a light output surface opposite the light input surface. Alternating transmissive regions and absorptive regions are disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30 and the alternating transmissive region and absorptive regions have a relative transmission at a viewing angle of 0 degrees of at least 75%.

Abstract: A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a reflective layer that is a locally-laminated reflective layer that is embedded between the transparent microsphere and the binder layer. At least some of the locally-laminated reflective layers may be localized reflective layers.

Abstract: A retroreflective article including a reflective-particle-containing binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements comprise a primary reflective layer that covers a portion of the embedded surface area of the transparent microsphere, and a secondary reflective layer provided by portions of the reflective-particle-containing binder layer that are adjacent to portions of the embedded surface area of the transparent microsphere that are not covered by the primary reflective layer.
