| titleOfInvention | Water-soluble triphendioxazine compounds |
| abstract | Water-soluble triphendioxazine compounds which have fiber-reactive properties as dyestuffs, which afford deep and fast dyeings on fiber materials, such as wool and, in particular, cellulose, and which correspond to the formula (1) <IMAGE> (1) in which: n is the number 0 or 1; Y is the vinyl group or an ethyl group containing, in beta -position, a substituent which can be eliminated by means of an alkali; Q1 and Q2 both represent a benzotriazole radical which can also be additionally substituted in the benzene nucleus by alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen, carboxy or sulfo; B is -O+13, -S-, -NH-or -N(R')-wherein R' is optionally substituted alkyl having 1 to 6 carbon atoms; W1 and W2 both represent a divalent, optionally substituted aliphatic, cycloaliphatic, aliphatic-cycloaliphatic, araliphatic or aromatic-carbocyclic radical, it being possible for the aliphatic radicals to be interrupted by hetero groups -O-, -S-, -SO2-, -CO-, 1,4-piperidino, -NH-and/or -N(Ro)-in which Ro is optionally substituted alkyl having 1 to 6 carbon atoms or alkanoyl having 2 to 5 carbon atoms, and/or for aliphatic and aryl radicals to be attached to one another through such a hetero group; R is hydrogen, alkyl having 1 to 6 carbon atoms, alkoxy having 1 to 6 carbon atoms, halogen, carboxyl or sulfo; E is hydrogen, sulfo, carboxyl, a group -SO2-Y as defined above or an optionally substituted sulfonamide group; and X1 and X2 are both hydrogen, cycloalkyl, alkoxy, aryloxy, aryl or another substituent; and at least one carboxy, sulfo or sulfato group is present in the molecule (1), and pre-products of those triphendioxazine compounds, of the general formula <IMAGE> (4) in which K is an amino or nitro group, Y' is beta -hydroxyethyl or defined as for Y, W has one of the meanings of W1, and E' is hydrogen, sulfo, carboxy or a group of the formula -SO2-Y' defined above, or an optionally substituted sulfonamide group, and R, B and R* have the above meanings. |
