2H-v-triazolo[4-5-d]pyrimidines
 Novel 2H-v-triazolo[4,5-d]pyrimidines of the general formula ##STR1## where R.sup.1 and R.sup.2 independently of one another are each alkyl, unsubstituted or substituted phenyl or phenalkyl, or ##STR2## is a saturated 5-membered or 6-membered heterocyclic ring, X is alkyl, halogen or phenyl n is 0, 1 or 2, and A is ##STR3## hydrogen, halogen, cyano, thiocyano, alkoxy, alkoxyalkoxy, unsubstituted or substituted phenoxy, phenylalkoxy, alkylthio, phenylthio, --S--(CH.sub.2).sub.m --COO-alkyl, where m is from 1 to 4, alkylcarbonyl, benzoyl, carboxyl, carboalkoxy, alkylsulfonyl, phenylsulfonyl, an N-imidazole, benzimidazole, 1,2,3-triazole, benzotriazole, 2-mercaptobenzothiazole, 2-mercaptobenzimidazole, 2-mercaptothiazole or 2-mercapto-1,3,4-thiadiazole radical, or a radical of the formula ##STR4## where R.sup.4 is H or C.sub.1 -C.sub.4 -alkyl, p is from 2 to 5 and R.sup.5 and R.sup.6 are each C.sub.1 -C.sub.4 -alkyl, or ##STR5## is a saturated 5-membered or 6-membered heterocyclic radical which can furthermore contain N, O and/or S as ring members, are useful charge carrier-transporting compounds in electrophotographic recording materials.
