Water-soluble disazo compounds containing an amino naphthol-disulfonic acid moiety as a coupling component and fibre-reactive groups |
摘要 |
Water-soluble disazo dyestuffs of the formula <IMAGE> which contain a 1-amino-8-naphthol-3,6- or -4,6-disulfonic acid moiety as a bivalent coupling component and which contain diazo components with fibre-reactive groups characterized by the inclusion of one or two chloro-triazinyl groups and one or two of the six groups defined by the substituent Z, namely, <IMAGE> CH2SO2CH2CH2OSO3H; SO2CHCH2; +TR <IMAGE> each of which are connected to the benzene moiety of the diazo component; the chloro-triazinyl group is further substituted by a substituted or unsubstituted phenylamino or substituted or unsubstituted naphthylamino group, a substitutent of which may be one of the six groups defined by the Z substituent; if there is only one chloro-triazinyl group in the compound, then the diazo component is also substituted by one of the Z substituents; these compounds are dyestuffs which exhibit a good fixation degree of the dyestuffs in fabrics.
