ABSTRACT OF THE DISCLOSURE The invention describes novel basic azo compounds of the formula Image (I) wherein X is one or more of the radicals (CH2,NR,CO(CH2)nA) and/or (SO2NH(CH2)nA), R is hydrogen or an alkyl group of 1 to 4 carbon atoms, A is a non-quaternised or quaternised basic radical, n is 1 to 4, is 1 to 4, M is hydrogen or any cation, p is 0 to 2, with the proviso that the value of m is as great or greater than p, and wherein the benzene radicals 8 optionally contain one or more identical or different substituents, selected from alkyl groups of 1 to 4 carbon atoms, halogen, alkoxy groups having 1 to 4 carbon atoms, NO2, OH, SO2NH2, SO2NH-alkyl C1-C4, SO2N(alkyl C1-C4)2, benzthiazol, SO2-heterocyclic with an N-atom linked to SO2, unsubstituted phenyl, and phenyl substituted by halogen and alkyl C1-C4, and the benzene radicals D optionally contain one or one identical or different substituents namely halogen, alkyl C1-C4 and alkoxy C1-C4. Methods of obtaining the novel compounds and their use as dyes, in particular for colouring and printing natural and regenerated cellulosic fabrics without the addition of salt, and also described.
