Metallizable disazo compounds having 1, 3-dihydroxybenzene bis-coupling component radicals, iron complexes thereof and mixtures of such iron complexes

摘要

Compounds of the formula IMAGE iron complexes thereof and mixtures of such iron complexes, wherein D is a monocyclic or bicyclic aromatic diazo component radical of the benzene series containing one -SO3M group or is IMAGE R1 is hydrogen, methyl or ethyl, and R4 is hydrogen, chloro or C1-2alkyl, wherein R' is hydrogen, C1-4alkyl, C2-4hydroxyalkyl, methoxy(C2-4alkyl) or IMAGE R'' is hydrogen, C1-4alkyl, C2-4hydroxyalkyl or methoxy(C2-4alkyl), or -NR'R'' is a saturated 5- or 6-membered ring, R5 is hydrogen, chloro or C1-2alkyl, and X is hydrogen or hydroxy, wherein each R2 is independently hydrogen, chloro, hydroxy, C1-2alkyl, C1-2alkoxy or -SO2NRoRo, and each R3 is independently hydrogen, C1-2alkyl, C1-2alkoxy, -COOM, trifluoromethyl or -NR'''R'''', wherein each R''' and R'''' is independently C1-4alkyl, C2-4hydroxyalkyl, methoxy(C2-4alkyl) or carbamoyl(C1-2alkyl), or -NR'''R'''' is saturated 5- or 6-membered ring, each Ro is independently hydrogen, C1-4alkyl, C2-4hydroxyalkyl or methoxy-(C2-4alkyl), or -NRoRo is a saturated 5- or 6-membered ring, and each M is independently hydrogen or a cation, which iron complexes and mixtures of iron complexes are useful for dyeing substrates dyeable with anionic dyes such as leather.Compounds of the formula IMAGE iron complexes thereof and mixtures of such iron complexes, wherein D is a monocyclic or bicyclic aromatic diazo component radical of the benzene series containing one -SO3M group or is IMAGE R1 is hydrogen, methyl or ethyl, and R4 is hydrogen, chloro or C1-2alkyl, wherein R' is hydrogen, C1-4alkyl, C2-4hydroxyalkyl, methoxy(C2-4alkyl) or IMAGE R'' is hydrogen, C1-4alkyl, C2-4hydroxyalkyl or methoxy(C2-4alkyl), or -NR'R'' is a saturated 5- or 6-membered ring, R5 is hydrogen, chloro or C1-2alkyl, and X is hydrogen or hydroxy, wherein each R2 is independently hydrogen, chloro, hydroxy, C1-2alkyl, C1-2alkoxy or -SO2NRoRo, and each R3 is independently hydrogen, C1-2alkyl, C1-2alkoxy, -COOM, trifluoromethyl or -NR'''R'''', wherein each R''' and R'''' is independently C1-4alkyl, C2-4hydroxyalkyl, methoxy(C2-4alkyl) or carbamoyl(C1-2alkyl), or -NR'''R'''' is saturated 5- or 6-membered ring, each Ro is independently hydrogen, C1-4alkyl, C2-4hydroxyalkyl or methoxy-(C2-4alkyl), or -NRoRo is a saturated 5- or 6-membered ring, and each M is independently hydrogen or a cation, which iron complexes and mixtures of iron complexes are useful for dyeing substrates dyeable with anionic dyes such as leather.
