    Abstract: An optical construction includes a reflective polarizer having a structured major surface, and an optically diffusive layer conformably disposed on the structured major surface so that opposing first and second major surfaces of the optically diffusive layer substantially conform to the structured major surface. The optically diffusive layer includes a plurality of nanoparticles defining a plurality of voids therebetween. For normally incident light and visible and infrared wavelength ranges: in the visible wavelength range and for a first polarization state, the optical construction has an average total transmittance of greater than about 40% and an average specular transmittance Vs; in the visible wavelength range and for an orthogonal second polarization state, the optical construction has an average total reflectance of greater than about 80%; and in the infrared wavelength range, the optical construction has an average specular transmittance Is, Is/ Vs ≥ 2.5.

    Abstract: An article is described comprising a substrate, a pressure sensitive polyacrylate primer layer disposed on the substrate, and an adhesive layer disposed onto the primer layer; wherein the adhesive layer comprises a polyacrylate component. The adhesive layer is typically further bonded to a second substrate or a release liner. In some embodiments, at least one substrate further comprises a microstructured surface layer and the primer layer is bonded to the microstructured surface layer. In other embodiments, the adhesive layer is further bonded to a (e.g. post) structure. In some embodiments, the articles are optical films or optical film stacks. Methods of making an (e.g. adhesive coated) article are also described.

    Abstract: An optical film includes an optically diffusive layer including a plurality of nanoparticles dispersed between and across opposing first and second major surfaces thereof. The plurality of nanoparticles has a nanoparticle size distribution including distinct first and second peaks at respective nanoparticle sizes d1 and d2, wherein 1.5 ≤ d2/d1 ≤ 10. The optically diffusive layer includes a polymeric material bonding the nanoparticles to each other. For a substantially collimated substantially normally incident light, the optical film has, in a visible wavelength, an average specular transmittance VTs and an average total transmittance VTt, and in an infrared wavelength range, an average total transmittance ITt and an average specular transmittance ITs, wherein 0.3 ≤ (VTs/VTt) ≤ 0.7, (VTs/ITs) ≤ 0.25, and (ITs/ITt) ≥ 0.7.

    Abstract: A backlight includes an extended light source adapted to emit light. A reflective polarizer is disposed on the extended light source, such that for substantially normally incident light and for at least a first wavelength in a range from about 420 nanometer (nm) to about 650 nm, the reflective polarizer reflects at least 60% of the incident light having a first polarization state and transmits at least 60% of the incident light having an orthogonal second polarization state. A first prismatic film is disposed between the extended light source and the reflective polarizer. A retarder layer is disposed between the reflective polarizer and the first prismatic film, such that for substantially normally incident light at a wavelength of about 550 nm, the retarder layer has a retardance nW, where n is an integer ≥ 1 and W is a wavelength between about 160 nm and about 300 nm.
