Abstract: A light control film is disclosed that includes a plurality of spaced apart first regions. Each first region has a substantially low transmission in one or two of a first wavelength range from about 300 nm to about 400 nm, a second wavelength range from about 400 nm to about 700 nm, and a third wavelength range from about 700 nm to about 1200 nm, and a substantially high transmission in the remaining wavelength ranges. The light control film has a viewing angle of less than about 70 degrees along a predetermined first direction.

Abstract: A prismatic retroreflective sheeting includes a structured layer that includes a plurality of cube corner elements including a reduced tungsten oxide, a radiation-treated region, and a non-radiation-treated region. The prismatic retroreflective sheeting includes also includes an information-containing layer above the structured layer. The information-containing layer includes at least one indicia defining an edge. The radiation-treated region of the structured layer is adjacent and below at least part of the edge of the at least one indicia.

Abstract: The present disclosure includes in one instance an optical article comprising a data rich plurality of retroreflective meats that are configured in a spatially defined arrangement, where the plurality of retroreflective elements comprise retroreflective elements having at least two different retroreflective properties, and where data rich means information that is readily machine interpretable. The present disclosure also includes a system comprising the previously mentioned optical article, an optical system, and an inference engine for interpreting and classifying the plurality of retroreflective elements wherein the optical system feeds data to the inference engine.

Abstract: Curable printing ink compositions include a visible light transparent, UV-curable binder composition and a visible light transparent, and infrared light absorbing inorganic composition. The infrared light absorbing inorganic composition can include infrared absorbing nanoparticles. The ink compositions are capable of flexographic printing at room temperature to a thickness of at least 1.0 micrometer. The cured ink composition has an infrared absorbance of at least 50%. The ink compositions can be printed in patterns of geometric features and cured to form articles.
