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 light control film includes a two-dimensional array of projections arranged across the light control film. A square of a magnitude of a Fourier transform frequency spectrum of the projections includes a plurality of distinct peaks separated by one or more valleys. The peaks and the one or more valleys have respective averages Pavg and Vavg, Pavg/Vavg≥5, such that when light from a substantially Lambertian light source is incident on the light control film, the light control film transmits the incident light with the transmitted light propagating along a transmission axis and having an intensity profile having a full width at half maximum of less than about 120 degrees in each cross-section of the intensity profile that comprises the transmission axis.

Abstract: An azido-containing monomer, a polymer containing monomeric units derived from the azido-containing monomer, and various articles containing a substrate and a coating layer of the polymer positioned on the substrate are provided. The azido groups, which are pendant groups of the polymer, can undergo a click chemistry reaction with an unsaturated compound such as those having a terminal —C≡CH group, a dibenzocyclooctyne-containing group, an unsaturated bicyclic olefinic group, or an amido group. The click chemistry reaction can be used to covalently attach a fluorescent or bioactive compound to the polymer.

Abstract: An optical system includes an optical film curved about a first axis and a light control film curved about the first axis and substantially coextensive with the optical film. The optical film includes a first layer including a microstructured first major surface where the microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending along the first axis. The first major surface of the optical film faces the light control film. The light control film includes a plurality of spaced apart optically absorptive regions extending along the first axis and along a direction substantially normal to a major surface of the light control film. At least one of the optical film or at least one layer disposed between the optical film and the light control film includes at least one reflection mitigation element.

Abstract: An optical film has a major surface including a plurality of microstructures. Each microstructure includes an optical facet and a sidewall meeting the optical facet at a ridge of the microstructure. The optical facet and the sidewall define an oblique angle therebetween. For each microstructure in at least a majority of the microstructures, an optically absorptive layer is disposed on the sidewall. The optical film can include a polymeric layer having a microstructured surface at least partially coated with an inorganic optically transparent layer. The optically absorptive layer can an average thickness t where 100 nm
