Abstract: Disclosed are metal complexes of trisazo dyes of the general formula 4 wherein R1 through R6 are as defined in the specification. 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.
