2,4,5-triphenyltriazoles of the formulas <IMAGE> in which R¹ and R² independently of one another for alkyl, phenalkyl, optionally substituted phenyl or <IMAGE> for a saturated 5- or 6-membered heterocyclic ring, X for alkyl,? Halogen? or phenyl, R³ and R <4> independently of one another for chlorine, bromine, alkyl, alkoxyalkyl, alkoxy, alkoxyalkoxy, alkylthio, phenyl, phenoxy, phenylthio or phenalkoxy, where the phenyl radicals are optionally substituted, or for <IMAGE> n for 0, 1 or 2, m and p each represent 0, 1, 2 or 3 and Z stands for a chemical bond or for> CH2,> 0,> S or> N-R¹. The compounds (I) and (II) are outstandingly suitable as charge-transporting compounds in electrophotographic recording materials. |
