Abstract:
A dye conforming to the general formula (1) whereinF is the residue of a polyazo dye, a derived heavy metal complex azo dye, an anthraquinone, azomethine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthene, nitroaryl, naphthoquinone, pyrenequinone, perylenetetracarbimide dye or is of the formula (X) Rx is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms, which may be substituted by halogen, hydroxyl, cyano, alkoxy of 1 to 4 carbon atoms, alkoxycarbonyl of 2 to 5 carbon atoms, carboxyl, sulfamoyl, sulfo or sulfato, n is 1 or 2; Q is a group of the general formula (2) whereinRz is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms, which may be substituted by halogen, hydroxyl, cyano, alkoxy of 1 to 4 carbon atoms, carboxyl, sulfamoyl, sulfo, sulfato, phenyl or phenyl substituted by substituents selected from the group consisting of halogen, alkoxy of 1 to 4 carbon atoms, alkyl of 1 to 4 carbon atoms, sulfo and carboxyl, or is a cyclohexyl radical, a phenyl radical or a phenyl radical substituted by substituents selected from the group consisting of halogen, alkoxy of 1 to 4 carbon atoms, alkyl of 1 to 4 carbon atoms, sulfo and carboxyl, W is alkyl-SO2â€”Y, alkyl-Het-alkyl-SO2â€”Y, where alkyl represents alkyl radicals of 1 to 4 carbon atoms, Het is â€”Oâ€”, â€”NHâ€”, â€”N(alkyl)- where alkyl represents alkyl radicals of 1 to 4 carbon atoms, â€”Sâ€”, or SO2 and Y is as defined below; A is zero or 1, and B is 1 or 2, the sum of (A +B) is 2 and in the event of B being 2 the groups of the formula â€”Wâ€”(SO2â€”Y)z being identical to or different from each other; V is a direct bond or an alkylene group or is a substituted or unsubstituted arylene radical or an alkylene-arylene or arylene-alkylene or alkylene-arylene-alkylene or arylene-alkylene-arylene radical or an arylene-arylene radical interrupted by one of the hetero groups indicated hereinafter, wherein the alkylene radicals are alkylene radicals of 1 to 8 carbon atoms and may be substituted, and the arylene radicals are substituted or unsubstituted phenylene or naphthylene radicals, and where the alkylene radicals may be interrupted by 1 or more hetero groups, and the alkylene and arylene moieties in the combined alkylene/arylene radicals may in each case be separated from each other by a hetero group; and said hetero group(s) contains at least one N, S or O atom, Y is 0, 1 or 2; z is 1 or2; h is for y=2 a nitrogen atom or for y=1 a group of the formula â€”NHâ€”, â€”N(R)â€”, â€”NHâ€”COâ€”NHâ€”, â€”COâ€”NHâ€” or a direct bond and wherein R is alkyl of 1 to 4 carbon atoms which is optionally substituted with sulfo, carboxyl, sulfato, phenyl or sulfophenyl, Y is vinyl or is an ethyl group &bgr;-substituted by an alkali-eliminable substituent, and the â€”SO2â€”Y group or groups may be attached to an aromatic carbon atom of F or V directly or via an alkylene radical of 1 to 4 carbon atoms or via an alkylamino group of 1 to 4 carbon atoms.
