DICHOLESTERYL ESTER COMPOUND AND RECORDING DISPLAY MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a dicholesteryl ester compound which is capable of reproducing a color in a low temperature region and has high color stability with the passage of time and which achieves recording or full color recording by a specific rewritable color, and also provide a recording display material using the same. SOLUTION: The dicholesteryl ester compound is represented by the general formula: YO-CO(CH2)n-O-R-O-(CH2)mCO-OY [wherein, Y represents a cholesterol residue which is obtained by removing a hydroxy group from a cholesterol with which the hydroxy group combines; R represents o-phenylene or m- phenylene; n and m represent each the same or different integer of 1-20].
