A trisazo compound represented by the following formula (I) in the free acid form:
wherein Q is an phenyl or naphthyl group both of which may be unsubstituted or substituted; one of the A and B is hydroxy group and the other is amino group; K is 1 or 2; and one of m and n is 1 and the other is 0; a method for dyeing fiber materials, paper or leather by using the trisazo compounds and an ink containing the trisazo compounds, and the trisazo compound is excellent in solubility, and good in storage stability and free from clogging of nozzle caused by deposition. The ink using the trisazo compound gives a deep black-colored image excellent in clarity, water-durability and durability to light.
