| titleOfInvention | Liquid crystalline dielectric, new dichroitic naphthoquinone dyestuffs and electro-optical indicator element |
| abstract | A liquid crystalline dielectric useful in electro-optical display elements based on the guest-host effect, comprises a liquid crystalline compound and a pleochroitic dyestuff of the formula ##STR1## wherein X and Y are the same or different and each is hydrogen, chlorine or bromine; R 1 , R 2 , R 3 and R 4 each independently is hydrogen, alkyl or alkoxyalkyl each of up to 8 C-atoms or a cyclic group Z, wherein Z is, ##STR2## and R is alkyl, alkoxy, alkoxyalkyl, alkoxyalkoxy or alkanoyloxy each of up to 8 C-atoms, with the proviso that at least one and at most two of R 1 , R 2 , R 3 and R 4 is cyclic group Z; and when two Z groups are present, either R 1 and R 2 or R 3 and R 4 are both a cyclic group Z; and, when R 3 and R 4 are both cyclic groups Z, these are in the 2- and 6- or 3- and 7-positions of the naphthalene structure. |
