Abstract

The present invention provides a red reactive dye capable of dyeing and printing the cellulosic fibrous material or the fibrous material containing the cellulosic fibers uniformly, vividly, darkly and reliably. In the present invention, the free acid form includes one or more kinds of fillers represented by the following general formula (I)

(Wherein m is 0 or 1, R ₁ is a hydrogen atom, a lower alkyl group or a lower alkoxy group: R ₂ and R ₃ are each independently a hydrogen atom, or a hydroxyl group, a cyano group, an alkoxy group, a carboxyl group). A carbamoyl group, an alkoxycarbonyl group, an alkylcarbonyloxy group, a sulfo group, a sulfamoyl group or a lower alkyl group unsubstituted or substituted with a halogen atom; A is one of a lower alkyl group, a lower alkoxy group, a sulfo group or a halogen atom or A phenylene group unsubstituted or substituted with two substituents, or a naphthylene group or a sulfonafthylene group: X ₁ is a halogen atom, —N (R ₄ ) R ₅ , or —OR ₆ (where R ₄ , R ₅ and R ₆ are each independently substituted with a hydrogen atom or a hydroxyl group, a cyano group, an alkoxy group, a carboxyl group, a carbamoyl group, an alkoxycarbonyl group, an alkylcarbonyloxy group, a sulfo group, a sulfamoyl group, or a halogen atom, or Or rain Substituted alkyl, phenyl or naphthyl): Y ₁ is a -SO ₂ CH = CH ₂ group or -SO ₂ CH ₂ CH ₂ Z ₁ R ₆ group (wherein Z ₁ , is separated by the action of an alkali) One or more dyes represented by the following general formula (ll) in the form of the free acid:

(Wherein n is 0, 1 or 2, and W ₁ and W ₂ are either hydrogen atoms, the other is a sulfo group: R ₂ is a hydrogen atom, or a hydroxyl group, a cyano group, an alkoxy group) , A carboxyl group, a carbamoyl group, an alkoxycarbonyl group, an alkylcarbonyloxy group, a sulfo group, a sulfamoyl group or a lower alkyl group unsubstituted or substituted with a halogin atom, B is a lower alkyl group, a lower alkoxy group, a sulfo group or a halogen atom Is a phenylene group unsubstituted or substituted with one or two substituents, or a naphthylene group or a sulfonaphthylene group: R ₂ is —N (R ₈ ) R ₉ , -OR ₁₀ , wherein R ₈ , R ₉ and R ₁₀ are each independently substituted with a hydrogen atom or a hydroxyl group, a cyano group, an alkoxy group, a carboxy group, a carbamoyl group, an alkoxycarbonyl group, an alkylcarbonyl oxy group, a sulfo group, a sulfamoyl group, or a halogen atom Or unsubstituted alkyl groups, phenyl Or a naphthyl group, or a substituted or unsubstituted or unsubstituted come flutes dini, morpholino group or a piperazinyl group ridges), and: Y ₂ in the group -S0 ₂ CH = CH ₂ or _{-S0 2 CH 2 CH 2 Z 1} ( here, Z ₂ is a group that can be separated by the action of an alkali).
