Fiber reactive anthraquinone dyes

A compound of the formula:

• ##STR163## wherein:
• ##STR164## W is independently selected from a direct covalent bond, an arylene selected from phenylene and naphthalene, or a C.sub.1 to C.sub.6 alkylene, or arylene-alkylene group wherein the alkylene group may be interrupted by a hetero atom selected from O, S and N;
• wherein said arylene moiety may be optionally substituted with Cl, Br, CH.sub.3, C.sub.2 H.sub.5, OCH.sub.3, SO.sub.3 H, COOH and OC.sub.2 H.sub.5
• R is independently selected from hydrogen, a C.sub.1 to C.sub.6 alkyl;
• a C.sub.1 to C.sub.6 alkoxy;
• sulfo and carboxy;
• R.sub.1 is selected from hydrogen, C.sub.1 to C.sub.6 alkyl and phenyl;
• R.sub.2 and R.sub.3 are independently selected from hydrogen, a C.sub.1 to C.sub.6 alkyl and --WSO.sub.2 Y;
• n is an integer of 1 or 2;
• X is F, Cl, HNCH, NR.sub.2 R.sub.3, OH or Q;
• and
• Y represents a fiber reactive group which is selected from CH.dbd.CH.sub.2 and CH.sub.2 CH.sub.2 --Z wherein Z is selected from the group consisting of Cl, Br, OSO.sub.3 H, SSO.sub.3 H and OPO.sub.3 H.sub.3.
