  An anthraquinone dye free from water-solubilising and ionic substituents of the general formula: wherein Q is NH2, OH, alkyl, aryl, N02 or halo; n is 0 to 4; each X independently is H, -SR, -NZ1Z2 or Q: each R independently is alkyl, aryl or cycloalkyl; Z1 & Z2 are independently H, alkyl, cycloalkyl or aryl; provided that there are at least two different -SR groups and that where only two X's represent -SR groups at least one R is aryl and the two -SR groups are in the 1 & 5 or the 1 & 8 positions. In addition to the normal textile applications the dye is suitable for use in the colouration of liquid crystals for electro-optic displays.

  The invention provides a light modulating material having at least a liquid crystal layer disposed between a pair of transparent electrodes. The liquid crystal layer has at least: a liquid crystal composition having at least one host liquid crystal having negative dielectric anisotropy and at least one dichroic dye; and at least one polymer material. The liquid crystal composition is vertically aligned when no voltage is applied, and the transmissivity of incident light of the light modulating material when no voltage is applied is higher than the transmissivity of incident light of the light modulating material when voltage is applied. The invention further provides a liquid crystal device that includes the liquid crystal layer.
