The cpds. are of general formula: (where a and A1 are the same or different C2-8 hydrocarbon residues opt. substd. by non-chromophor residues, R1 and R2 are the same of different C1-5 lower alkyl groups or H atom, R3 - R6 are the same or different C1-5 lower alkyl groups, and R3 - R4 and R5 - R6 may form a hydrogenated heterocyclic ring with the N atom, or they are cycloalkyl, aralkyl or aryl groups, R7 and R8 are the same or different C1-5 lower alkyl groups or benzyl group or H atom, and X is a colourless anion). They are produced by reacting the condensation product of 1 mole 4,41-diamino-stilbene-disulphoacid-2,21 and 2 moles cyanuric chloride with 2 moles of a diamine of general formula: condensing the product with a diamine of formula: precipitating the product with the cpd. R7X (where X is an anionic residue), and reacting the precipitated product with a cpd. R8X. The products are esp. useful for treating cellulose threads. |
