Abstract

PURPOSE: To provide titled compsn. which is colored red by the application of electric voltage consisting of a specified anthraquinone compd. and a nematic liquid crystal.
CONSTITUTION: (B) 0.1W3% of an anthraquinone cpd. of the formula (wherein R is 2W15C straight or branched chain alkyl) [obtd. by reacting 1-amino-4-hydroxy- 2-phenoxy(or-2-methoxy-or-2-halogeno)-anthraquinone with an alcohol of formula R1-OH (wherein R1 is the same as R) in the presence of an alkali], is blended with (A) a nematic liquid crystal to obtain the desired compsn. for liquid crystal color display. The compsn. has large dichroic ratio, exhibits large contrast ratio by the application of voltage-no voltage, excels in durability, is stable, and does not lower the performance of a device even though the device is used for many hours.
