Abstract: The invention provides a dye mixture consisting essentially of a dye of the formula (4) and a dye of the formula (5). The black dye mixture is used with advantage for inkjet printing and gives highly light-stable and neutral-black ink formulations. A dye mixture consisting essentially of one or more dyes of the formula (4) and one or more dyes of the formula (5) in which Y is H, (C1-C6)-alkyl, (C1-C6)-alkoxy or halogen; R1 is OM, CH=CH2, CH2CH2OR2, CH2CH2NR3R4, CH2CH2SR5 or CH2CH2CR6R7R8, R2 is H, SO3M, (C1-C6)-alkyl, (C1-C6)-alkyl substituted by one or more radicals from the group consisting of OH, NH2, COOM and SO3M; (C1-C6)-acyl, (C6-C10)-aryl, (C6-C10)-aryl substituted by one or more radicals from the group consisting of halogen, OH, NH2, COOM and SO3M; or 5-10-membered heterocycles containing from 1 to 4 heteroatoms from the group consisting of O, N and S; R3 and R4 independently of one another are H, (C1-C6)-alkyl, (C1-C6)-alkyl substituted by one or more radicals from the group consisting of OH, MH2, COOM and SO3M; (C1-C6)-acyl, (C6-C10)-aryl, (C6-C10)-aryl substituted by one or more radicals from the group consisting of OH, halogen, NH2, COOM and SO3M; or NR3R4 forms a heterocycle; R5 is (C1-C6)-alkyl, (C1-C6)-alkyl substituted by one or more radicals from the group consisting of OH, NH2, COOM and SO3M; (C1-C6)-acyl, (C6-C10)-aryl, (C6-C10)-aryl substituted by one or more radicals from the group consisting of OH, halogen, NH2, COOM and SO3M, or SR5 forms a heterocycle; R6, R7 and R8 independently of one another are H, (C1-C6)-alkyl, or (C1-C6)-alkyl substituted by one or more radicals from the group consisting of halogen, OM, NH2, COOCH3, COOM and SO3M; or one or two of the radicals R6, R7 and R8 is or are COOM; R9 is a (C6-C14)-aryl radical substituted one or more times by OM, O(C1-C6)-alkyl, O(C1-C6)-alkyl-COOM, O(C1-C6)-alkyl-SO3M, O(hydroxy(C1-C6)-alkyl), (C1-C6)-alkyl, COOM, SO3M, SO2NH2, SO2N(hydroxy(C1-C6)-alkyl)2, SO2NH(C1-C6)-alkyl, SO2N((C1-C6)-alkyl)2, NH2, NH(C1-C6)-alkyl, NH(C1-C6)-acyl, NH(C6-C10)-aryl, N(hydroxy(C1-C6)-alkyl)2, N((C1-C6)-alkyl)2 and/or halogen; R10 is OM, O(C1-C6)-alkyl, COOM, SO3M, COO(C1-C6-alkyl) or SO3(C1-C6-alkyl); R11, R12 and R13 are identical or different and are H, OM, O(C1-C6)-alkyl, O(C1-C6)-alkyl-COOM, O(C1-C6)-alkyl-SO3M, O(hydroxy(C1-C6)-alkyl), (C1-C6)-alkyl, COOM, SO3M, SO2NH2, SO2N(hydroxy(C1-C6)-alkyl)2, SO2NH(C1-C6)-alkyl, SO2N((C1-C6)-alkyl)2, NH2, NH(C1-C6)-alkyl, NHacyl, NH(C6-C14)-aryl, N(hydroxy(C1-C6)-alkyl)2, N((C1-C6)-alkyl)2, or halogen, R14 is a monocyclic or bicyclic, carbocyclic or heterocyclic, aromatic or aliphatic ring which is unsubstituted or substituted one or more times by OM, (C1-C6)-alkyl, O(C1-C6)-alkyl-COOM, O(C1-C6)-alkyl-SO3M, O(hydroxy(C1-C6)-alkyl), (C1-C6)-alkyl, COOM, SO3M. SO2NH2, CONH-phenyl, SO2NH-phenyl, SO2N(hydroxy(C1-C6)-alkyl)2, SO2NH(C1-C6)-alkyl, SO2N((C1-C6)-alkyl)2, NH2, NH(C1-C6)-alkyl, NH(C1-C6)-acyl, NH(C6-C10)-aryl, N(hydroxy(C1-C6)-alkyl)2, N((C1-C6)-alkyl)2, halogen and/or phenylsulfo and can contain 1, 2 or 3 of the heteroatoms N, O and/or S in the ring; M1 stands for a monovalent or polyvalent metal atom, and M is hydrogen, a monovalent metal cation, one equivalent to a polyvalent metal cation, or an ammonium ion unsubstituted or substituted by (C1-C14)-alkyl, (C1-C4)-alkoxy-(C1-C4)-alkyl, hydroxy-(C1-C4)-alkyl, benzyl or (C6-C10)-aryl.
