Black trisazo metal complex dyes

Disclosed are metal complexes of trisazo dyes of the general formula 4 where R1 is aryl substituted by one or more, eg. 2, 3, 4 or 5, substituents selected from the group consisting of OH, O(C1-C6)-alkyl, O(C1-C6)-alkyl-COOM, O(C1-C6)-alkyl-SO3M, O(hydroxy(C1-C6)-alkyl), (C1-C6)-alkyl, COOM, SO3M, S...

Summary:Disclosed are metal complexes of trisazo dyes of the general formula 4 where R1 is aryl substituted by one or more, eg. 2, 3, 4 or 5, substituents selected from the group consisting of OH, 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, NHaryl, N(hydroxy(C1-C6)-alkyl)2, N((C1-C6)-alkyl)2 and halogen; R2 is OH, O(C1-C6)alkyl, COOM or SO3M; R3, R4 and R5 are each hydrogen or a substituent; R6 is a mono- or bicyclic carbocyclic or heterocyclic aromatic which is unsubstituted or substituted by one or more substituents, or is a similarly substituted pyrazole or pyridone radical. The dyes are useful for dyeing and printing natural and synthetic fiber materials, recording fluids, especially for the inkjet process, liquid formulations for paper pulp dyeing, and also as colorants for electrophotographic toners, powder coatings and color filters including the dyes of the invention.
