Title:
OPTICALLY ACTIVE COMPOUND, OPTICAL RECORDING MATERIAL, OPTICAL FILM, AND INFORMATION RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2007/102590
Kind Code:
A1
Abstract:
Disclosed is an optically active compound represented by the general formula (I): (I) wherein X1, X2, X3 and X4 independently represent -NH2, -N(CH3)2, -H, -CpF2p+1, -SCqH2q+1, -CrH2r+1, -OCsH2s+1, -F, -I, -Br, -Cl, -COOH, -COOCtH2t+1, -CONH2, COCH3, -CHO, -NO2 or -CN (wherein p, q, r, s and t independently represent an integer of 1 to 10); and a and b independently represent an integer of 1 to 6. The optically active compound has a high sensitivity and rapid responsibility.
