Abstract

The present invention relates to novel .alpha.-(4-biphenylyl)-benzyl-azolium salts of the general formula ##STR1## in which A represents the CH group or a N atom PA1 R.sup.1 and R.sup.2 are identical or different and each represents hydrogen, alkyl or optionally substituted phenyl, PA1 R.sup.3 represents hydrogen, alkyl, or an optionally substituted phenyl, phenylalkyl, phenylcarbonyl or phenylcarbonylalkyl group, PA1 X represents halogen, alkyl, halogenoalkyl, alkoxy, alkylthio, nitro or cyano, PA1 Y represents X or optionally substituted phenyl, PA1 m and n each represents 0 or an integer from1 to 5 and PA1 Z represents the anion of an inorganic or organic acid. The invention also includes processes for the preparation of the compounds and, in addition includes compositions containing the compounds and methods for their use. The compounds of the invention exhibit antimicrobial activity and sporicidal activity.
