WATER-INSOLUBLE MONAZO-DYESTUFFS CONTAINING A DIAMINO TRIAZINYLAMINO GROUP

摘要

Procedure for obtaining water-insoluble monoazo dyes of the general formula (1) ** (See formula) ** where D represents the rest of a diazo component of the benzene series, which may be substituted by halogen atoms and/or lower alkyl or alkoxy groups, perfluoroalkyl, alkylsulfonyl, arylsulfonyl, carbalkoxy, carbamyl, cyano or nitro groups, Y a hydrogen or halogen atom, a lower alkyl, alkoxy or acylamino group, Z a hydrogen or halogen atom, a lower alkyl or alkoxy group, R a hydrogen atom or a lower alkyl group, which may carry other substituents, To an alkyl moiety with 1 to 6 carbon atoms, and B and C, which may be the same or different, a lower alkoxy group or an amino group that may bear one or two other substituents - characterized by the fact that diazotines of the general formula (2) D-NH2 (2) -in which D has the meaning indicated above- and join with azo components of the general formula (4) ** (See formula) ** where Y, Z, R, A, B and C have the meanings indicated above.
