Abstract
Process for the preparation of azoic cationic dyes, lacking sulphonic or carboxylic groups, soluble in h2o and having the structural formula: ** (see formula) ** Wherein: r = alkyl, aralkyl, r'= alkyl having 1 to 4 carbon atoms; r "= hydrogen, alkyl having 1 to 4 carbon atoms, halogen; r'''= alkyl (1 to 4 carbon atoms), either unsubstituted or substituted with a halogen, cyano (-cn), hydroxy (-oh), alkoxy (or), acyloxy (-ocor); y = cyano group (-cn), amido (-conh2), acyloxy (-ocor), carbalkoxy (-coor); x- = anion, characterized by the fact that an amine of the type: ** (see formula) ** Is diazotized, and by the fact that the diazo compound is then coupled with an amine corresponding to the general formula: ** (see formula) ** In which the groups r and y have the same meaning indicated for these letters in claim 1, thereby obtaining dyes of the types ** (see formula) ** Which are subsequently quaternized according to conventional methods.
