Abstract:
The present invention relates to films made from mixed cellulose esters having low hydroxyl content and certain plasticizers. These films can exhibit +C plate, −A plate, and biaxial Nz behavior, which make them particularly suitable for use in optical applications, such as in liquid crystal displays (LCD) as protective and compensator films.
