Abstract
There is provided a bisazo compound which is useful as a reactive dye for dyeing or printing a fiber material in an orange to scarlet or red color; the bisazo compound being represented by the following formula (1): ##STR1## wherein m and n represents 0 or 1; W represents a divalent connecting group represented by --NH-- or --NHCONH--; D.sup.1 and D.sup.2 represent a group represented by the following formula (2a), (2b), (2c) or (2d) ##STR2## wherein Y represents --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 L, in which L represents a group eliminatable by the action of an alkali.
