摘要： A multilayer optical body is disclosed and includes a light reflecting element formed from a first polymer material and a second polymer material having an index of refraction difference sufficient to reflect light of at least one polarization, and at least one non-optical warp-resistant layer disposed on the light reflecting element. The at least one non-optical one warp-resistant layer includes an intimate mixture of i) polystyrene or a first polystyrene copolymer and ii) a second polystyrene copolymer or ii) a polyester or copolyester.

摘要： A multi-layered biaxially oriented film comprising at least one primary layer and at least one secondary layer, wherein the primary layer comprises a propylene copolymer having a first melting point and the secondary layer comprises a polypropylene homopolymer or copolymer having a second melting point, such that the second melting point is greater than the first melting point and the multi-layered construction is biaxially stretched. The multi-layered film further includes a surface finishing layer, to provide a writable multi-layered film. This stretched film exhibits a refractive index in the machine direction (MD) that is greater than the refractive index measured in the transverse direction (TD).

摘要： An optical film includes a layer of simultaneous biaxially stretched polyolefin film that is substantially non-absorbing and non-scattering for at least one polarization state of visible light. The layer has x, y, and z orthogonal indices of refraction where at least two of the orthogonal indices of refraction are not equal. The layer has an in-plane retardance of 100 nm or less and an absolute value of an out-of-plane retardance being 55 nm or greater.

摘要： A process for making an optical film includes stretching a polyolefin film in a first direction and stretching the polyolefin film in a second direction different than the first direction forming a biaxially stretched polyolefin film. At least a portion of the stretching of the polyolefin film in the second direction occurs simultaneous with the stretching of the polyolefin film in the first direction. The biaxially stretched polyolefin film has a length and a width and substantially non-absorbing and non-scattering for at least one polarization state of visible light. The biaxially stretched polyolefin film has x, y, and z orthogonal indices of refraction where at least two of the orthogonal indices of refraction are not equal, an in-plane retardance being 100 nm or less and an out-of-plane retardance being 50 nm or greater.
