Document Type and Number:
Japanese Patent JP5453798
Kind Code:
B2
Abstract:
The present invention provides an optical film obtained by polymerizing a compound containing a group represented by formula (A) and at least one polymerizable group. CGa-Da-Ar-Db-Gb- (A), (Ar represents a divalent group having at least one aromatic ring selected from a group consisted of aromatic hydrocarbon ring and aromatic heterocyclic ring, wherein the total number N [pi] of [pi] electron of the aromatic ring contained in the divalent group is 12 or more. Da and Db each independently represents single bond, -CO-O-, -O-CO-, -C(=S)-O-, -O-C(=S)-, -CR1R2-, -CR1R2-CR3R4-, -O-CR1R2-, -CR1R2-O-, -CR1R2-O-CR3R4-, -CR1R2-O-CO-, -O-CO-CR1R2-, -CR1R2-O-CO-CR3R4-, -CR1R2-CO-O-CR3R4-, -NR1-CR2R3-, -CR2R3-NR1-, -CO-NR1-or-NR1-CO-. Ga and Gb each independently represents divalent aromatic hydrocarbon group or divalent aromatic heterocyclic group).
