The present invention relates to an optical film which is excellent in transparency, heat resistance and workability. Specifically disclosed is an optical film containing a polymer having at least a repeating unit represented by the following general formula (I). (I) [In the formula, R<1> and R<3> independently represent a hydrogen atom, a linear or branched alkyl group having 1-4 carbon atoms, or a substituted or unsubstituted phenyl group; R<2>, A and B independently represent a hydrogen atom, a halogen atom, a linear or branched alkyl group having 1-4 carbon atoms, a linear or branched halogenated alkyl group having 1-4 carbon atoms, a linear or branched alkoxy group having 1-4 carbon atoms, an alkoxycarbonyl group, an acyloxy group, an amino group, an azido group, a nitro group, a cyano group or a hydroxyl group (in this connection, R<2> is not a hydrogen atom); and l, m and n respectively represent an integer of not less than 2]. |
