Abstract
PURPOSE: To provide a guest-host type liquid crystal compsn. which contains a red polychromic coloring matter having good order parameter, absorptivity coefficient, stability and solubility, containing an anthraquinone coloring matter.
CONSTITUTION: There is provided a liquid crystal compsn. obtd. by incorporating at least one anthraquinone coloring matter of formula I (wherein X is substd. phenoxy, substd. alkoxy, substd. thioalkoxy) into a liquid crystal. Examples of the anthraquinone coloring matters are cpd. of formula II (wherein R1 is H, CnH2n+1, OCnH2n+1, SCH3, cyclohexyl, phenyl; n is 1W18), cpd. of formula III (wherein R2 is CnH2nCN, CnH2nCOOCH3; n is 1W5), cpd. of formula IV (wherein R3 is CnH2nCN, CnH2nCOOH3; n is 1W5) and cpd. of formula V (wherein Y is O, S; R4 is CnH2n+1; n is 1W18).
