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.

Claim (Index 2):
The single layer optical film of  claim 1 , wherein said DS OH  is at least 0.40, wherein the sum of C2DS aryl  and C3DS aryl  minus C6DS aryl  is in the range of from about 0.22 to about 0.50.
