    摘要: Basic azo dyestuffs of the general formula ##STR1## and tautomers thereof, in which D is the radical of a diazo or tetrazocomponent free of anionic groups,X is O or NH,R.sup.1, R.sup.2 are hydrogen, alkyl or aryl,B is a bridge member andR.sup.3, R.sup.4 are hydrogen, alkyl, alkenyl or aralkyl orR.sup.2 and R.sup.3 together with B and the two nitrogen atoms to which they are bonded form a 5- or 6-membered heterocyclic and in this caseB also stands for a direct bond, orR.sup.3 and R.sup.4 together with the nitrogen atom to which they are bonded form a 5- or 6-membered heterocyclic,n is 1 or 2, and in whichthe cyclic and acyclic radicals can in turn be substituted by radicals customary in dyestuff chemistry, find utility for dyeing and coloring synthetic and natural materials.
