Abstract: An optical stack for reflecting and transmitting light in a predetermined wavelength range includes stacked first and second optical films, the predetermined wavelength range defining a first wavelength range and a remaining wavelength range. For normally incident light and for each wavelength in a first wavelength range, the first optical film substantially reflects light having a first polarization state, and substantially transmits light having a second polarization state. For each of the first and second polarization states, for wavelengths in the first wavelength range, the second optical film has a maximum optical transmittance Tmax for light incident at a first incident angle, and an optical transmittance Tmax/2 for light incident at a second incident angle, where the second incident angle is greater than the first incident angle by less than about 50 degrees. For wavelengths in the remaining wavelength range, the second optical film reflects at least 80% of light.

Abstract: An article including a reflector with a reflectance band that is substantially constant as a function of an incidence angle; a polymeric multilayer film packet including a front surface partial reflector with a reflectivity that increases with an increasing incidence angle away from the normal; and a wavelength-selective absorber with a transmission band that at least partially coincides with the reflectance band of the reflector.

Abstract: Optical stacks are described. In particular, optical stacks including reflecting-absorbing polarizers and quarter-wave plates are disclosed. The optical core of the optical stack—which includes a reflecting-absorbing polarizer with at least one skin layer including polarizing dye—may be co-extruded or co-stretched.

Abstract: A polarizer including an oriented polymeric first layer is described. The oriented polymeric first layer is preparable from a mixture of polyvinyl alcohol and crosslinker where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, in that for U=(1/MDDR−1)/(TDDR1/2−1), U is at least 0.85, with MDDR being a machine direction draw ratio and TDDR being a transverse direction draw ratio.

Abstract: Multilayer reflective polarizers are described. More particularly, multilayer reflective polarizers having a higher block light transmission at longer wavelengths than shorter wavelengths while having a high pass light transmission are described. The described multilayer reflective polarizers may be combined with absorbing polarizers or used in display devices.

Abstract: An optical film including a thermoplastic birefringent multilayer optical film and a UV-cured layer disposed adjacent an outer layer of the multilayer optical film is described. The outer layer may a thickness in a range of about 0.3 micrometers to about 1.2 micrometers and the UV-cured layer includes a structured surface opposite the outer layer. The UV-cured layer may have a Tg less than about 30° C. and has a pencil hardness in a range of 2B to 2H.
