ABSTRACT:
Naphthalene derivatives of the fomula I ##STR1## in which: R.sup.1 is an alkyl or alkenyl radical which is unsubstituted, monosubstituted by CH or CF.sub.3 or monosubstituted by halogen and has 1 to 15 carbon atoms, it also being possible for one or more CH.sub.2 groups in these radicals to be replaced, in each case independently of one another, by --O--, --S--, ##STR2## --CO--, --CO--O--, --O--CO-- or --O--CO--O-- in such a manner that oxygen atoms are not linked directly to one another, ##STR3## m is 0, 1 or 2, n is 0 or 1, where
m+n is 1 or 2,
Z.sup.1 and Z.sup.2 are each, independently of one another, --CH.sub.2 CH.sub.2 --, --C.tbd.C-- or a single bond,
L.sup.1 and L.sup.2 independently of one another, are H or F,
x is an alkyl or alkoxy radical which is unsubstituted, monosubstituted by CN or CF.sub.3 or substituted bi halogen and has 1 to 15 carbon atoms, or is OH, CN, SCN, OCN, NCS or Q--Y,
where
Q is a single bond, (CF.sub.2).sub.r or O(CF.sub.2).sub.r
r is 1 or 2, and
Y is H, F, Cl or Br,
with the provisos that
a) in the case where
m=0, Z.sup.2 =a single bond, n=1 and x=CH CF.sub.3 or SCN, L.sup.1 is F,
b) in the case where
m=0, Z.sup.2 =a single bond, n=1 and X=alkyl, alkoxy or F a L.sup.1 and L.sup.2 are identical and are F.
