摘要：
A monoazo compound of the following formula,
wherein D is sulfonaphthyl, sulfophenyl or carboxyphenyl, any one of A 1 and A 2 is sulfo and the other is hydrogen, methoxy or ethoxy, R 1 and R 2 are independently hydrogen or alkyl, B 1 and B 2 are independently phenylene or naphthylene, and Y 1 and Y 2 are indpendently vinyl, β-sulfatoethyl or the like, which is useful for dyeing or printing fiber materials to give dyed or printed products of a deep color excellent in fastness properties.
