| titleOfInvention | LIQUID CRYSTAL DIELECTRIC |
| abstract | The invention relates to a liquid-crystalline dielectric for electro-optical display elements, which contains at least one dye of the formula (I) <IMAGE> in which X and X', independently of one another, are S or NH, L and L', independently of one another, are H, Ar or branched alkyl having 3-5 carbon atoms, A and A', independently of one another, are H, Cl, Br, NH2, mono- or dialkylamino, in each case having 1-3 carbon atoms in the alkyl groups, or anilino, R and R', independently of one another, are 4-Z-cyclohexyl-Y<1>-, 4-Z-1-cyclohexenyl, 4-Z-1-hydroxycycloalkyl, 4-Z-cyclohexyl- idenemethyl, Ar-Y<2>- or COOR<1>, R' is alternatively H, Cl or Br, Z is H, alkyl or alkoxy, each having 1-8 carbon atoms, Ar is an aryl group which is unsubstituted or substituted by alkyl-Y<2>- having 1-8 carbon atoms, aryl-Y<2> or 4-Z-cyclohexyl, Y<1> is -CHOH-, -CHOalkanoyl- having 1-6 carbon atoms in the alkanoyl group, or a bond, Y<2> is O, S, NH or a bond, and R<1> is H, alkyl having 1-8 carbon atoms, 4-Z-cyclohexyl, aryl, 4-Z-cyclohexylaryl or 4-Z-cyclohexylarylalkyl having 1-4 carbon atoms in the alkyl moiety, where each of the aryl groups contains 6-14 carbon atoms, and/or contains at least one of the salts of this dye. |
