  Provided are a coloring matter for black ink which is highly soluble in water-based media, and ink compositions containing the same. A high-concentration aqueous solution and ink that contain the coloring matter are stable even when have been stored for a long period, and can produce printed images having extremely high density. Even when printing is conducted using the high-concentration aqueous solution, no bronzing occurs in the resulting printed images. The ink compositions can produce black recorded images which exhibit various excellent fastnesses, particularly excellent light fastness and ozone gas fastness. The coloring matter consists of at least one substance selected from among trisazo compounds represented by general formula (1), tautomers thereof, and salts of both. In general formula (1), R 1 is unsubstituted C 1-4 alkyl or the like; R 2 is cyano or the like; R 3 is a chlorine atom or the like; R 5 to R 7 are a hydrogen atom, unsubstituted C 1-4 alkyl, sulfo-substituted C 1-4 alkoxy, or the like; R 8 to R 10 are a hydrogen atom, unsubstituted C 1-4 alkyl, sulfo-substituted C 1-4 alkylthio, or the like; A is sulfo-substituted 2-naphthothiazolyl or the like; and a to d represent the positions at which the ring is substituted with R 3 and sulfo.
