Claims
- 1. Aryl hydrazides of the Formula: ##STR4## wherein R.sub.1 to R.sub.5 are radicals which can be the same or different, at least one of which, however, is not hydrogen, and which are represented by hydrogen, halogen, alkyl, alkoxy, hydroxy alkyl, halogenated alkyl, alkyl amino, aliphatic acyl amino, with, in each case, one to 20 carbon atoms, cycloalkyl with 5 to 7 carbon atoms, aryl, aryloxy, or aryl carbonyl amino with, in each case, six to ten carbon atoms, aralkyl or aralkoxy with one to three carbon atoms in the alkylene chain, an aliphatic acyl amino radical with one to four carbon atoms and substituted with a phenoxy radical optionally substituted with one or more alkyl radicals with one to ten carbon atoms,
- Q.sup.+ is 3-alkyl-imidazole-1-yl or 3-alkenyl imidazole-1-yl, optionally substituted, whereby the substituents can be alkyl, alkenyl, aminoalkyl, hydroxyalkyl radicals, benzyl, phenyl, phenylmethyl or carboxyl, carbamide, carboxyalkyl or hydroxy groups, trialkylammonium ethyl groups, amino, monoalkylamino and dialkylamino groups or chlorine, and whereby all alkyl groups of a radical Q.sup.+ can be the same or different and/or can be substituted with hydroxyl or sulfonic acid groups, each alkyl group having, however, 12 carbon atoms at most,
- B is a bridge that can contain one to three methylene groups, an oxygen atom, and --CO--NH-- or --NH-- groups, or, if it is not directly attached to a quaternary nitrogen, can also consist of a simple bond, whereby the methylene groups and --NH-- groups themselves can be substituted with methyl or ethyl groups, and
- A.sup.- is an anion that is omitted if Q.sup.+ contains a sulfo group or a carboxyl group.
- 2. The aryl hydrazides of claim 1, wherein one of the radicals R.sub.1 to R.sub.5 or Q.sup.+ is substituted with a radical of the formula
- R.sub.6 --X--CS--X'--
- wherein one of X or X' is represented by NR.sub.7 and the other is represented by NR.sub.8, O, or S; and wherein R.sub.6, R.sub.7 and R.sub.8 are represented by hydrogen and alkyl, cycloalkyl, or aryl groups with up to eight carbon atoms.
- 3. The aryl hydrazines of claim 1, wherein Q.sup.+ is a substituted or unsubstituted 3-alkyl or 3-alkenyl imidazole-1-yl.
