Tetrakisazo Compound, Coloring Matter for Recording, Ink Composition and Colored Article

The present invention relates to black coloring matter, and relates to a compound represented by the following formula (1): (wherein A and D independently represent an optionally substituted phenyl group or naphthyl group, respectively, and m and n represent 1 or 2, respectively), and the coloring matter for recording and an ink comprising the same. Said compound exhibits high solubility in a medium containing water as a main component, is stable even when an aqueous dye solution or an ink having a high concentration is prepared therefrom and is stored for a long period of time, has low color rendering property, exhibits colorless and neutral black, provides a printed image having high density and also provides a black recorded image being excellent in moisture fastness, light fastness and an ozone gas fastness, and further can be synthesized easily and can be produced at a low cost.
