Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

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 disposed between the light input surface and the light output surface, wherein the absorptive regions comprise a core having a first concentration, C1, of a light absorbing material sandwiched between cladding layers having a second concentration, C2, of the light absorbing material, wherein C2

Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses selectively located barriers to the adhesive regions. A structurally weak wavelength-selective material includes portions that contact the adhesive regions and break to remain in contact with the adhesive. The wavelength-selective material does not contact the adhesive regions covered by the barrier and is removed leaving a wavelength-selective film in a pattern at the adhesive regions.
