ABSTRACT:
The fibre-reactive formazan dyes of the formula ##STR1## where B is an aliphatic or sulfo-free aromatic bridge member, R is .alpha.,.beta.-dihalopropionyl, .alpha.-haloacryloyl or haloacetyl, T.sub.1 is halogen, X is halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, cyano or nitro, Y is --CO-- or --SO.sub.2 --, Z is nitrogen or --C--T.sub.2, T.sub.2 is halogen, hydrogen, C.sub.1 -C.sub.4 alkylthio, cyano, formyl or C.sub.1 -C.sub.4 alkylsulfonyl, m is 1, 2 or 3, n is 0, 1 or 2, qu is 0 or 1 and r and s are each eitehr 0 or 1 but never the same as each other, produce dyeings having good fastness properties on nitrogen-containing or hydroxyl-containing fibre materials.
