Abstract: Multi-layer films, and processes to make the films, that enable the delivery of a substrate featuring a peelable thin layer of low haze, amorphous, isotropic film with the desired properties of high modulus, high usage temperature, UV blockage, and toughness. The films are made using a co-extrusion, co-orientation and annealing process to enable the delivery of a thin isotropic, UV blocking layer on top of a release layer and support substrate. These film constructions can be kept together during additional processing steps such as coating and converting. The release and dimensionally stable substrate layer can be easily removed once processing steps are completed.

CPC classification number: G02B5/305 , G02B5/0841
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: An optical film includes a plurality of polymeric layers shaped along orthogonal first and second directions. A first curve being an intersection of the optical film with a first plane orthogonal to the second direction and to a reference plane has a best-fit first circular arc subtending a first angle at a center of curvature of the first circular arc of greater than 180 degrees where the optical film has a maximum projected area in the reference plane. A second curve being an intersection of the optical film with a second plane orthogonal to the first direction and to the reference plane has a best-fit second circular arc subtending a second angle at a center of curvature of the second circular arc of at least 30 degrees. Reflectance and transmittance of the optical film are described.

CPC classification number: G02B27/0988 , G02B5/003
Abstract: A light control film includes opposing substantially planar substantially parallel first and second major surfaces spaced apart along a thickness direction of the light control film by less than about 500 microns; and a plurality of substantially parallel optically transparent polymeric columns disposed in, and substantially surrounded by, a light absorbing polymeric material. Each of the polymeric columns has a first column end at the first major surface and an opposite second column end at the second major surface and has an aspect ratio of greater than about 3, such that the first column ends of at least one pair of adjacent polymeric columns include substantially parallel substantially straight sides facing, and substantially coextensive with, each other.

CPC classification number: G02B5/305 , G02B5/26 , G02B5/3083
Abstract: A multilayer optical film includes a plurality of optical repeat units which may number less than about 175 in total and which may have a combined average thickness of less than about 20 micrometers. Each of the optical repeat units includes at least four individual layers which may include at least one polymeric A layer, at least two B layers, and at least one polymeric C layer. At least one layer in the at least four individual layers can have an average thickness of less than about 50 nm. An interlayer adhesion of the individual layers in the plurality of optical repeat units can be at least about 14 grams per inch when measured at a 90 degree peel angle. The multilayer optical film may be a reflective polarizer or a multilayer optical mirror.

Abstract: Optical films having a curved shaped and methods of shaping optical films are described. A method of shaping an optical film includes the steps of disposing the optical film adjacent first and second rollers spaced apart along a first direction, securing opposing first and second ends of the optical film, providing a curved mold surface, and shaping the optical film by contacting the optical film with the curved mold surface while stretching the optical film along the first direction and keeping a threshold distance between closest points on the optical film contacting the first roller and contacting the curved mold surface less than the width of the optical film to reduce buckling of the optical film.

Abstract: A feedblock including a first packet creator that forms a first packet including a first plurality of polymeric layers, the first plurality of layers including at least four first individual polymeric layers; and a second packet creator that forms a second packet including a second plurality of polymeric layers, the second plurality of layers including at least four second individual polymeric layers, wherein the first and second packet creators are configured such that, for each packet creator, respective individual polymeric layers of the plurality of polymeric layers are formed at approximately the same time. The feedblock may include a packet combiner that receives and combines the first and second primary packets to form a multilayer stream. In some examples, at least one of the first and second primary packets may be spread in the cross-web direction prior to being combined with one another.
