CELLULOSE ESTER OPTICAL FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY USING THE CELLULOSE ESTER OPTICAL FILM, AND METHOD FOR PRODUCING CELLULOSE ESTER OPTICAL FILM

摘要

Disclosed is a cellulose ester optical film characterized by containing a cellulose ester, a polymer (a) defined below and a compound (b) defined below. (a) a polymer obtained by copolymerizing an ethylenically unsaturated monomer having a partial structure represented by the general formula (1) below in a molecule and at least one ethylenically unsaturated monomer (b) at least one compound selected from the group consisting of carbon radical scavengers, phenol compounds and phosphorus compounds. (In the formula, R1, R2 and R3 independently represent an optionally substituted aliphatic group, an optionally substituted aromatic group or an optionally substituted heterocyclic group; or alternatively any two of R1, R2 and R3 may combine and form a ring structure together with a nitrogen atom or with a nitrogen atom and a carbon atom to which they are bonded to.)
