1. Water-soluble disazo compounds of the general formula (1) see diagramm : EP0087113,P21,F3 in which : M is a hydrogen atom or the equivalent of a metal ; R is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms an alkoxy group of 1 to 4 carbon atoms or a sulfo group ; D is a radical of the formula (4a) see diagramm : EP0087113,P21,F4 in which M has the above-mentioned meaning and n represents the number 1, 2 or 3, however, with the proviso that in the case the triazinylamino group is bonded to the benzene nucleus in paraposition relative to the indicated group -SO3 M and R represents at the same time a hydrogen atom, D is the 3-sulfo-1-naphthyl, 4-sulfo-1-naphthyl, 6-sulfo-1-naphthyl, 7-sulfo-1-naphthyl, 3,6-disulfo-1-naphthyl, 3,7-disulfo-1-naphthyl, 4,6-disulfo-1-naphthyl, 4,7-disulfo-1-naphthyl, 5,7-disulfo-1-naphthyl, 3,5,7-trisulfo-1-naphthyl, 3,6,8-trisulfo-1-naphthyl, 4,6,8-trisulfo-1-naphthyl, 5-sulfo-2-naphthyl, 6-sulfo-2-naphthyl, 7-sulfo-2-naphthyl, 8-sulfo-2-naphthyl, 3,6-disulfo-2-naphthyl, 5,7-disulfo-2-naphthyl, 6,8-disulfo-2-naphthyl or the 4,6,8-trisulfo-2-naphthyl r,8-disulfo-2-naphthyl or the 4,6,8-trisulfo-2-naphthyl radical ; the sulfo group of the formula MO3 S- in the aminonaphthol radical is bonded to the naphthalene nucleus in the meta- or para-position relative to the amino group ; R**1 is a hydrogen atom, an alkyl group of 1 to 4 carbon atoms, an alkoxy group of 1 to 4 carbon atoms or a chlorine atom ; R**2 is a hydrogen atom, an alkyl group of 1 to 4 carbon atoms, an alkoxy group of 1 to 4 carbon atoms or a chlorine atom ; Y is a chlorine atom or a fluorine atom ; Z is the vinyl group or a beta-sulfatoethyl group. |
