Abstract: Multilayer optical films are described. In particular, multilayer optical films that include both birefringent high index layers and low index layers are disclosed. The low index layers can be a glycol-modified polyethylene terephthalate. These optical films can be reflective polarizers and may be particularly suitable for automotive, architectural, and industrial applications.

Abstract: A multilayer partial mirror includes a plurality of alternating first a second polymeric layers numbering at least 50 in total, disposed between, and integrally formed with, opposing first and second polymeric skin layers. For a visible wavelength range extending from about 420 nm to about 680 nm and an incident light propagating in an incident plane that includes a x-direction, and for an s-polarized incident light, the multilayer partial mirror has an average reflectance Rs1 for a first incident angle of less than about 10 degrees, and an average reflectance Rs2 for a second incident angle of greater than about 45 degrees, and for a p-polarized incident light, the multilayer partial mirror has an average reflectance Rp1 for the first incident angle, and an average reflectance Rp2 for the second incident angle. Each of Rs2/Rs1 and Rp2/Rp1 is greater than about 1.15.

Abstract: A multilayer optical film includes a plurality of optical repeat units. Each of the optical repeat units includes at least four sequentially arranged first through fourth layers including first and third layers having respective f-ratios f1 and f3. The optical film has a first order reflection band having a reflection peak height Rp1 and any second order reflection band has a reflection peak height Rp2, where Rp1/Rp2≥5. Rp1/Rp2 may remain at least 5 when changing at least one of the f-ratios f1 and f3 continuously by 0.2. A thickness of each of the second and fourth layers can be less than a thickness of each of the first and third layers by at least a factor of 2, or a thickness of a same one of the first and third layers can differ from a thickness of each other layer by at least a factor of 2.5.

Abstract: Polyester copolymeric materials include 40 to 51 mol % substituted naphthalate units, such as dimethyl-2,6-naphthalene dicarboxylate units, 10 to 40 mol % ethylene units, and 10 to 40 mol % hexane units. The polyester copolymers can be used to prepare multi-layer optical films by coextrusion and/or co-stretching. The copolyester polymeric materials have desirable optical properties and permit thermal processing at lower temperatures.
