Dye mixtures for dye transfer

Claim 1

Dye mixtures comprising at least one azo dye of the formula I ##STR36## where R 1 , R 2 and R 3 are identical or different and each is independently of the others alkyl, alkoxyalkyl, alkanoyloxyalkyl, alkoxycarbonyloxyalkyl or alkoxycarbonylalkyl, each of which may have up to 20 carbon atoms and be phenyl-, C 1 -C 4 -alkylphenyl-, C 1 -C 4 -alkoxyphenyl-, halophenyl-, benzyloxy-, C 1 -C 4 -alkylbenzyloxy-, C 1 -C 4 -alkoxybenzyloxy, halobenzyloxy-, halogen-, hydroxyl- or cyano-substituted, hydrogen, unsubstituted or C 1 -C 4 -alkyl- or C 1 -C 4 -alkoxy-, halogen- or benzyloxy-substituted cyclohexyl or a radical of the formula [--E--O].sub.m --R.sup.5, where E is C 2 -C 6 -alkylene, M is 1, 2, 3, 4, 5 or 6, and R 5 is C 1 -C 4 -alkyl or unsubstituted or C 1 -C 4 -alkyl- or C 1 -C 4 -alkoxy-substituted phenyl, R 4 is C 1 -C 4 -alkyl, R 6 is cyano or carbamoyl, and D is the radical of a diazo component, and at least one dye of the formula II, III and/or IV ##STR37## where L 1 is C 1 -C 20 -alkyl, which may be substituted and may be interrupted by from 1 to 4 oxygen atoms in ether function, substituted or unsubstituted phenyl or hydroxyl, L 2 is a 5- or 6-membered carbocyclic or heterocyclic radical, L 3 is cyano, carbamoyl, carboxyl or C 1 -C 4 -alkoxy-carbonyl, L 4 is oxygen or a radical of the formula ##STR38## where Q 1 is in each case C 1 -C 8 -alkyl, which may be interrupted by 1 or 2 oxygen atoms in ether function, X is CH or nitrogen, L 5 is hydrogen or C 1 -C 4 -alkyl, L 6 and L 7 are identical or different and each is independently of the other hydrogen, substituted or unsubstituted C 1 -C 12 -alkyl, C 5 -C 7 -cycloalkyl, substituted or unsubstituted phenyl, substituted or unsubstituted pyridyl, substituted or unsubstituted C 1 -C 12 -alkanoyl, C 1 -C 12 -alkoxycarbonyl, substituted or unsubstituted C 1 -C 12 -alkylsulfonyl, C 5 -C 7 -cycloalkylsulfonyl, substituted or unsubstituted phenylsulfonyl, substituted or unsubstituted pyridylsulfonyl, substituted or unsubstituted benzoyl, pyridylcarbonyl or thienylcarbonyl, or together with the nitrogen atom joining them together are unsubstituted or C 1 -C 4 -alkyl-substituted succinimido, unsubstituted or C 1 -C 4 -alkyl -substituted phthalimido or a five- or six-membered saturated heterocyclic radical, which may contain further hetero atoms, Y is cyano or a radical of the formula CO--Q 2 , CO--OQ 2 or CO--NHQ 2 , where Q 2 is hydrogen, C 1 -C 8 -alkyl, which may be substituted and may be interrupted by 1 or 2 oxygen atoms in ether function, C 5 -C 7 -cycloalkyl, phenyl or tolyl, the dye mixture containing from 10 to 90% by weight of the dye mixture of dye of formula I and 90 to 10% by weight of the dye mixture of one or dyes of the formulas II, III and/or IV.
