<p>Described are water-soluble trisazo compounds of the below-indicated and -defined general formula (1), which are suitable for use as fibre-reactive dyes for dyeing fibre materials based on cellulose of natural and synthetic origin, for example cotton and filament viscose, and in addition can be used as dyes for inks which can be used in inkjet printing. <IMAGE> where M is hydrogen or an alkali metal, Y and Z, which are different from each other, are each hydroxyl or amino, D<1> is a radical of the formula (2a) and D<2> is a radical of the general formula (2b) <IMAGE> where R<1> is hydrogen or lower alkoxy, R<2> is hydrogen, lower alkyl or lower alkoxy, X is vinyl or beta -sulphatoethyl, R<3>, R<4> and R<7> are each hydrogen or sulpho, and R<5> and R<6> are each hydrogen, hydroxyl or amino. The trisazo compounds are preferably present in the form of mixtures.</p> |
