Document Type and Number:
Japanese Patent JP3590863
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cholesteric liquid crystal compound that has good photorespontivity and shows high storage stability of the fixed color without acceleration of crystallization, even when it is held at room temperature after the color fixation and provide a optical recording medium comprising the liquid crystal compound. SOLUTION: The objective liquid crystal compound is represented by the following general formula (1) (wherein A is H or a 1-20C organic group, Y is an azo-benzene group; Z is a cholesteryl group; R is a 2-30C divalent organic group), has the molecular weight of <=3,000, the glass transition point of >=35 deg.C and this liquid crystal compound is used to obtain the objective optical recording medium.
