<P>PROBLEM TO BE SOLVED: To provide an optical film which exhibits reverse wavelength dispersibility or flat wavelength dispersibility and has satisfactory durability. <P>SOLUTION: The optical film contains a compound represented by the specified general formula (1). (In the formula (1), Cyc represents a cyclic group including a divalent 5-membered ring or 6-membered ring, where the 5-membered ring or 6-membered ring may be condensed with another ring; R<SB POS="POST">3</SB>represents a substituent in the cyclic group; j represents an integer from 0 to 4, and when j is equal to 0, the 5-membered ring or 6-membered ring is condensed with another ring; L<SB POS="POST">1</SB>and L<SB POS="POST">2</SB>each independently represent a divalent linking group selected from the group consisting of a single bond, -O-, -CO-, -NRa- (Ra is a C1-C7 alkyl group or a hydrogen atom), -S-, -SO<SB POS="POST">2</SB>- and -CH<SB POS="POST">2</SB>-; Str<SB POS="POST">1</SB>and Str<SB POS="POST">2</SB>each independently represent a residue of steroid; R<SB POS="POST">1</SB>and R<SB POS="POST">2</SB>each independently represent a substituent; and m and n each independently represent an integer from 0 to 10.) <P>COPYRIGHT: (C)2013,JPO&INPIT |
