The invention relates to fluoro-chloro-benzene derivatives of formula (I), wherein R denotes an alkyl or halogenoalkyl residue of up to 12 C atoms wherein one or two non-adjacent CH2 groups may also be replaced by -O- and/or -HC=CH-, the radical A is a ring of formula (1) or (2), Q is a bivalent radical of formula (1) or (2) or a single bond or -if radical A denotes trans-1,4-cyclohexylene- is also a bivalent radical of the formulae (3),(4), or (5), and L?0, L1 and L2¿ are each independently H or F, with the proviso that at least one of L?0, L1 and L2¿ present in the molecule denotes F. |
