Abstract

Ammonium compounds of the formula (I) ##STR1## in which at least one of the radicals R.sub.1 to R.sub.4 denotes a fluorine-containing alkyl radical having 4 to 30 carbon atoms and not more than three of the radicals R.sub.1 to R.sub.4 independently of one another denote hydrogen atoms or alkyl or hydroxyalkyl radicals having 1 to 30 carbon atoms, and R.sub.5 to R.sub.8 denote aryl, alkylaryl or halogenoaryl radicals or fluorine atoms, and iminium compounds of the formula (II) ##STR2## in which Q, together with the constituent ##STR3## forms a ring system having 4 to 17 carbon atoms, which can be interrupted by 1 to 4 hetero atoms and contain 2 to 9 double bonds, and which can be substituted by fluorine, chlorine, bromine or iodine atoms or alkyl (C.sub.1 -C.sub.6), alkoxy (C.sub.1 -C.sub.6), nitro or amino groups, R.sub.9 denotes a fluorine-containing alkyl (C.sub.1 -C.sub.30) radical, R.sub.10 denotes a hydrogen, fluorine, chlorine, bromine or iodine atom or an alkyl(C.sub.1 -C.sub.6), alkoxy (C.sub.1 -C.sub.6), nitro or amino group and the radicals R.sub.11 to R.sub.14 denote aryl radicals, alkylaryl radicals, halogenoaryl radicals or fluorine atoms, and mixtures of these compoun…
