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: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, an absorptive layer or reflective layer is disposed between the alternating transmissive regions and absorptive regions and the light input surface and/or light output surface. In another embodiment, the alternating transmissive regions comprise an absorptive material. The light control film can exhibit low transmission of visible light and high transmission of near infrared light. Also described is a light detection system comprising such light control films and a microstructured film.
