Warm-colored cholesteric liquid crystal composition

Abstract

The present invention provides a cholesteric liquid crystal composition exhibiting warm hues. [Solution] A cholesteric liquid crystal composition containing the following components (A) to (C) is used. (A) One or more sterols selected from cholesterol, dihydrocholesterol, lanosterol, dihydrolanosterol, desmosterol, stigmasterol, sitosterol, campesterol, brassicasterol, phytosterol, ergosterol, and γ-oryzanol (B) Two or more sterol esters, one or more selected from each of at least two groups B1 to B3 below. Group B1: Esters of fatty acids selected from acetic acid, propionic acid, butyric acid, and valeric acid with sterols. Group B2: Esters of fatty acids selected from caprylic acid, nonanoic acid, capric acid, and lauric acid with sterols. Group B3: Esters of fatty acids selected from palmitoleic acid, oleic acid, linoleic acid, isostearic acid, and 12-hydroxystearic acid with sterols, and cholesteryl oleyl carbonate. (C) Esterilized succinic acid and sterol
