    • Cationic dyestuffs of the formula[(D--N.dbd.N--K) (--R).sub.n ].sup.m.sym. m An.crclbar.whereinD denotes the radical of a diazo component,K denotes the radical of a coupling component,m and n independently of one another denote 1 or 2,An.crclbar. denotes an anion andR denotes a radical of the general formulae--A--O --(B--O).sub.p --E--A--O--CO--F--O--(B--O).sub.p --E or--A--(O--F).sub.p.sbsb.1 --CO--O--(B--O).sub.p --EwhereinA represents optionally substituted alkylene with 2 to 4 C-atoms or a direct bond,B represents optionally substituted alkylene with 2 to 4 C atoms,E represents hydrogen or optionally substituted alkyl, alkenyl, cycloalkyl, formyl, alkylcarbonyl or alkenylcarbonyl or optionally substituted phenylcarbonyl, phenylalkylcarbonyl, phenoxyalkylcarbonyl, phenylalkyl or phenyl,F represents alkylene,p represents 1-3 andp.sub.1 represents 0 or 1,at least one of the radicals A or B represents substituted alkylenepossess good coloristic properties. The dyestuffs are characterized by good water solubility, good fastness to light and to wet processing and have affinity to fibers, as well as good migrating capacity and substantial insensitivity to thiocyanate ions.
