| titleOfInvention | USE OF ANIONIC AZOIC COLORS AND THEIR METALLIC COMPLEXES FOR THE DYING OF LEATHERS |
| abstract | Use of anionic azo dyes and their transition metal complexes, which have at least one acid group in the form of their salt and at least 2 azo groups and whose dye anion is described by the general formula (1), wherein : Q, R, T, U and V, independently of each other, represent a residue derived from benzene, naphthalene, diphenylamine, diphenylmethane, phenylaminosulfonylbenzene or phenylaminocarbonylbenzene, and Q and U may also represent a residue derived from pyrazole, thiazole, triazole, isothiazole or thiadiazole, where Q, R, TU and V may be, in addition to the optionally present anionic A-group, present one or more of the following moieties as substituents: OH, NH2, NO2, halogen, C1-4 alkyl, C1-4 hydroxyalkyl, C1-4 alkoxy, C1-4 alkylamino, C1-4 dialkylamino, C1-4 alkylaminocarbonyl, C1-4 dialkylaminocarbonyl, C1-4 alkylcarbonylamino, N- (C1-4 alkylcarbonyl) -N- (C1-4 alkylcarbonyl), phenylcarbonylamino , formamide or a 5 or 6 member heterocycle linked to N, where Q and U, independently of one another, may also have a substituent -N = NP, where P may represent an aromatic moiety, selected from the group phenyl, naphthyl, pyridyl, 2-pyridonyl, pyrazolyl and thiazolyl and which may be optionally substituted by one or more of the following moieties: OH, NH2, NO2, halogen, C1-4 alkyl, C1-4 hydroxyalkyl, C1-4 alkoxy, C1-4 alkylamino, C1-4 dialkylamino, C1 alkylaminocarbonyl -4, C1-4 dialkylaminocarbonyl, C1-4 alkylcarbonylamino, N- (C1-4 alkylcarbonyl) -N- (C1-4 alkylcarbonyl) amino, phenylcarbonylamino, formamide or a N or 5-membered saturated nitrogen heterocyclyl, eg, morpholinyl, piperazinyl or pyrrolidinyl; S represents a remainder of the (2) or (3); wherein X and Y in the formula (2) independently represent one another, OH, NH2, C1-4 alkyl, C1-4 hydroxyalkyl, C1-4 alkoxy, C1-4 alkylamino, C1-4 dialkylamino or a saturated heterocyclyl of 5 or 6 members linked to N, W represents in the formula (3) a bond, O, NH, SO2, SO2NH, CONH or C1-4 alkylene, R1, R2 independently represent one another, hydrogen, OH or C1- alkyl 4, and Z is the same or different and represents COOH or hydrogen; A- can be the same or different and are selected from CO2 and SO3; k, l, m, n and o may be the same or different and represent 0, 1 or 2, where the sum pk + l + m + qn + ro means at least 1; p and q independently represent one another, 0 or 1; comprising lithium ions and sodium ions in a molar ratio of 1:19 to 4: 1 and especially in a molar ratio of 1: 9 to 3.5: 1, for leather dyeing. Procedure for dyeing leather by treating the leather with an aqueous bath containing a dye, which contains at least one anionic azo dye or an anionic transition metal complex of an azo dye as described above. |
