ABSTRACT:
A red reactive dye having the following formula (I) in its free acid form: ##STR1## wherein X is --CH.dbd.CH.sub.2 or --C.sub.2 H.sub.4 W (wherein W is a group splittable by alkali), A is a C.sub.2-3 alkylene group or a C.sub.2-3 alkylenoxy C.sub.2-3 alkylene group, E is a hydrogen atom, a C.sub.1-3 alkyl group or --A--SO.sub.2 X (wherein A and X are as defined above), n is 0 or 1, l is 1 or 2, m is 0 or 1, and R is a hydrogen atom, --OH, --CN, --CH.sub.3, --CF.sub.3, --SO.sub.3 H, --COOH, --CH.sub.2 SO.sub.3 H or --CH.sub.2 SO.sub.2 X (wherein X is as defined above), provided that a compound of the formula (I) wherein R is a hydrogen atom, each of m and n is 0, l is 1, and --SO.sub.2 X is --SO.sub.2 CH.dbd.CH.sub.2 which is bonded at the ortho position to the azo group, is excluded.
