Abstract

NEW MATERIAL:A dye of formulaI(R1WR4 are H, hydroxyl, amino; R5 is alkyl, alkoxy, alkyl-substituted amino; R6 is H, lower alkyl, alkoxy, halogen).
USE: Dichrmic dye for liquid crystal of yellow to purple. A color liquid crystal composition is prepared from the dye and a nematic liquid crystal.
PREPARATION: The condensation reaction between 2-hydroxy-3-aminoanthraquinone derivative of formula II and an acid chloride of formula III is effected by heating them in an inert solvent such as nitrobenzene.
