Abstract

Cyclohexane derivatives of the formula I EQU R.sup.1 --A.sup.1 --Z.sup.1 --A.sup.2 --R.sup.2 I in which PA0 R.sup.1 and R.sup.2 are each an alkyl group having 1-10 C atoms, in which one or two non-adjacent CH.sub.2 groups can also be replaced by O atoms and/or --CO-- groups and/or --CO--O-- groups and/or --CH.dbd.CH-- groups, one of the radicals R.sup.1 and R.sup.2 also being H, F, Cl, Br, CN or R.sup.3 --A.sup.3 --Z.sup.2 --, PA0 A.sup.1 is --A--, A.sup.4 --A-- or --A--A.sup.4 --, PA0 A is a trans-1,4-cyclohexylene group which can be substituted in the 2-, 3-, 5- and/or 6-position one or more times by F and/or Cl and/or Br and/or CN and/or an alkyl group or a fluorinated alkyl group which each have 1-10 C atoms and in which one or two non-adjacent CH.sub.2 groups can also be replaced by 0 atoms and/or --CO-- groups and/or --CO--O-- groups, and which may also be substituted in the 1- and/or 4-position, PA0 A.sup.2, A.sup.3 and A.sup.4 are each 1,4-phenylene which is unsubstituted or substituted by one or two F and/or Cl atoms and/or CH.sub.3 groups and/or CN groups and in which one or two CH groups can also be replaced by N atoms and/or NO; 1,4-cyclohexylene in which one or two non…
