Abstract

PURPOSE: The titled composition that is made by dissolving an anthraquinonecarboxylic ester of a specific structure in a liquid crystal as a dichromatic dye, thus developing bright red to blue color and showing good dichromatic property with high light resistance.
CONSTITUTION: The objective composition is prepared by dissolving an anthraquinonecarboxylic ester of the formula[X is H, amino, hydroxyl, halogen; R is cyclohexyl, phnyl, biphenyl substitutable with halogen, alkylalkoxy, -Alk-Y (Al is 1W15C alkylene; Y is 1W15C alkoxy, nitrile, H, phenyl substitutable with 1W14C lower alkyl or nitrile], e.g., obtained by esterification of 1,4-diaminoanthraquinone-4-carboxylic acid with an alcohol of R-OH, in a liquid crystal, preferably by 0.01W5% as a dichromatic dye to produce the objective composition.
