ABSTRACT:
A reactive dye composition containing at least one dye of the formula (I) in the free acid form: ##STR1## wherein m is zero or 1; R.sub.1 is hydrogen, lower alkyl or lower alkoxy; R.sub.2 and R.sub.3 are independently hydrogen or substituted or unsubstituted lower alkyl; A is substituted or unsubstituted phenylene or naphthylene; X.sub.1 is halogen, --N(R.sub.4)R.sub.5 or --OR.sub.6 in which R.sub.4, R.sub.5 and R.sub.6 are independently hydrogen or substituted or unsubstituted alkyl, phenyl or naphthyl; and Y.sub.1 is the group --SO.sub.2 CH.dbd.CH.sub.2 or the group --SO.sub.2 CH.sub.2 CH.sub.2 Z.sub.1 in which Z.sub.1 is a group splittable by the action of an alkali, and at least one dye of the formula (II) in the free acid form: ##STR2## wherein n is zero, 1 or 2; one of W.sub.1 and W.sub.2 is hydrogen and the other is sulfo; R.sub.7 is hydrogen or substituted or unsubstituted lower alkyl; B is substituted or unsubstituted phenylene or naphthylene; X.sub.2 is --N(R.sub.8)R.sub.9, --OR.sub.10 in which R.sub.8, R.sub.9 and R.sub.10 are independently hydrogen or substituted or unsubstituted alkyl, phenyl, naphthyl, pyridinio, morpholino or piperidino; and Y.sub.2 is the group --SO.sub.2 CH.dbd.CH.sub.2 or the group --SO.sub.2 CH.sub.2 CH.sub.2 Z.sub.2 in which Z.sub.2 is a group splittable by the action of an alkali, dyes or prints cellulose fiber materials or fiber materials containing a cellulose fiber to give a vivid, deep and highly fast red color.
