    摘要： A bisazo compound of the following formula:

    wherein R¹ and R³ are each hydrogen or alkyl; D is phenylene or naphthylene; one of X¹ and X² is NH₂ and the other is OH; Z¹ and Z² are each -CH=CH₂ or -CH=CH₂Z' in which Z' is a splittable group; B is monosulfophenylene, monosulfophenylene-methylene or mono- or disulfonaphthylene-methylene; U is phenylene or an aliphatic bridging group; and J is an amono-derivative group or, J may be alkoxy when X¹ is OH and U is phenylene, and J may be alkoxy or phenoxy when X¹ is OH and U is the aliphatic bridging group. This compound is useful for dyeing or printing fiber materials and gives a dyed or printed product having a color superior in various fastness properties with superior build-up property.
