Document Type and Number:
WIPO Patent Application WO/2007/058041
Kind Code:
A1
Abstract:
Disclosed is 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, R1 and R3 independently represent a hydrogen
atom, a linear or branched alkyl group having 1-4 carbon atoms, or a substituted
or unsubstituted phenyl group; R2, 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, R2 is not a hydrogen atom); and
l, m and n respectively represent an integer of not less than 2.]
