Abstract

New cyclohexane derivatives of the formula I EQU R.sup.1 --A.sup.1 --Z.sup.1 --A.sup.2 --R.sup.2 I wherein PA1 R.sup.1 and R.sup.2 are each H, an unsubstituted or substituted alkyl group with 1-15 C atoms, it also being possible for one or two non-adjacent CH.sub.2 groups to be replaced by at least one grouping from the group comprising --O--, --CO--, --O--CO--, --CO--O--, --C.tbd.C--, --CH.dbd.CH--, --S--, --SO-- and --SO.sub.2 --, F, Cl, Br, CN or R.sup.3 --(A.sup.3).sub.p --Z.sup.2 --, PA1 A.sup.1 is --A--, --A.sup.4 --Z.sup.3 --A-- or --A--Z.sup.3 --A.sup.4 --, PA1 A is a 1,4-cyclohexylene group which is substituted in the 1- and/or 4-position by unsubstituted or substituted alkyl or fluorinated alkyl with in each case 1-5 C atoms, it also being possible for one or two non-adjacent CH.sub.2 groups to be replaced by one grouping from the group comprising --O--, --CO--, --O--CO--, --CO--O--, --C.tbd.C--, --CH.dbd.CH--, --S--, --SO-- and --SO.sub.2 --, or by F, Cl, Br, CN and/or --CHO, and which can carry 1 or 2 further substituents, PA1 A.sup.2, A.sup.3 and A.sup.4 in each case denote 1,4-phenylene which is unsubstituted or substituted by one or two F and/or Cl atoms and/or CH.su…
