Abstract: Regioselectively substituted cellulose esters having a plurality of aryl-acyl substituents and a plurality of alkyl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in optical films, such as optical films having certain Nz values, −A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.

Abstract: The present invention relates to a multilayer cellulose ester film having a reversed optical dispersion. The film can have an A-B bi-layer or an A-B-A tri-layer configuration. The cellulose ester material for layer A has a hydroxyl degree of substitution (DSOH) from 0 to 0.5, while the cellulose ester material for layer B has a DSOH from 0.5 to 1.3. By manipulating the thickness of layers A and B, and the film stretching conditions, desirable optical retardation and optical dispersion properties can be obtained. The film can be used as an optical waveplate in liquid crystal displays to improve viewing angle, contrast ratio, and color shift.
