Abstract
A reactive dye represented by the formula (I), ##STR1## wherein R represents --NH.sub.2 or --NHC.sub.2 H.sub.4 SO.sub.3 M, and M's independently represent Li.sup..sym., Na.sup..sym., K.sup..sym. or .sup..sym. NH(C.sub.2 H.sub.4 OH).sub.3, provided that at least one of M's represents Li.sup..sym. or .sup..sym. NH(C.sub.2 H.sub.4 OH).sub.3. This reactive dye easily gives a stable liquid composition and is useful to dye cellulosic or polyamide fibers.
