ABSTRACT:
A fluorinated compound having a formula: ##STR1## R.sub.1 is hydrogen or alkyl having up to 12 carbon atoms; R.sub.2 is selected from hydrogen, alkyl having up to 12 carbon atoms, alkoxy having up to 12 carbon atoms, ##STR2## wherein R.sub.3 is hydrogen or alkyl having up to 12 carbon atoms, and wherein R.sub.4 is hydrogen, alkyl having up to 12 carbon atoms or alkoxy having up to 12 carbon atoms; ##STR3## represents a cyclohexane ring which is in the trans configuration if 1, 4-disubstituted; ##STR4## represents a benzene ring; each of X, Y and Z independently represents hydrogen or fluorine in one or more of the lateral benzene ring positions, provided that at least one of X, Y and Z is present representing fluorine;
