MATERIALS, CONFIGURATIONS, AND METHODS FOR REDUCING WARPAGE IN OPTICAL FILMS |
摘要 |
<p>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.</p> |
