Process for dyeing or printing and novel reactive dyes

A process for dyeing or printing paper, films of plastic or fibre material containing hydroxyl groups or containing nitrogen with reactive dyes, which comprises using at least one reactive dye of the formula (1) from the following group a) and at least one reactive dye from the following groups b), c) and d):

• a) green- or blue-dyeing reactive dyes of the formula (1) 77
• in which
• NiPhC is the radical of a nickel phthalocyanine,
• R1 is hydrogen or substituted or unsubstituted C1-C4alkyl,
• V1 is hydrogen or substituted or unsubstituted C1-C8alkyl, phenyl or naphthyl and
• x is 2 to 4 and y is 1 to 2,
• the reactive dye of the formula (1) containing at least one fibre-reactive group;
• b) blue-dyeing reactive dyes of the formula (2) or (3) 78
• in which
• (R2)0-3 is 0 to 3 C1-C4alkyl radicals which are identical or different from one another and
• (R3)0-3 is 0 to 3 substituents, which are identical or different from another, from the group consisting of C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl and sulfo,
• X1 is chlorine or fluorine and
• R4 is hydrogen or C1-C4alkyl which is unsubstituted or substituted by hydroxyl, sulfo or sulfato, 79
• in which
• R5 is hydrogen or C1-C4alkyl which is unsubstituted or substituted by hydroxyl, sulfo or sulfato,
• X2 is chlorine or fluorine,
• Y1 is hydrogen, C1-C8alkyl which is unsubstituted or substituted by hydroxyl, sulfo or sulfato and uninterrupted or interrupted by oxygen, or phenyl or naphthyl which are unsubstituted or substituted by C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl or sulfo, and the benzene nuclei I, II and III contain no further substituents or are further substituted by C1-C4alkyl, C1-C4alkoxy, halogen or carboxyl;
• c) red-dyeing reactive dyes of the formula (4) 80
• in which
• R6 is hydrogen or C1-C4alkyl which is unsubstituted or substituted by hydroxyl, sulfo or sulfato,
• R7 and R8 independently of one another are hydrogen, C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl or sulfo,
• X3 is chlorine or fluorine and
• Y2 is hydrogen, C1-C8alkyl which is unsubstituted or substituted by hydroxyl, sulfo, sulfato or a radical of the formula —SO2—Z and is uninterrupted or interrupted by oxygen, or phenyl or naphthyl which are unsubstituted or substituted by C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl, sulfo or a radical of the formula —SO2—Z or —CO—NH—(CH2)2-3—SO2—Z, or the radical —N(R6)—Y2 is morpholino, in which
• Z is a radical of the formula —CH═CH2 or —CH2—CH2—U1 and U1 is a leaving group;
• d) yellow- or orange-dyeing reactive dyes of the formula (5) 81
• in which
• R9 is hydrogen or C1-C4alkyl which is unsubstituted or substituted by hydroxyl, sulfo or sulfato,
• R10 and R11 independently of one another are hydrogen, C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl or sulfo,
• X4 is chlorine or fluorine and
• Y3 is hydrogen, C1-C8alkyl which is unsubstituted or substituted by hydroxyl, sulfo or sulfato and is uninterrupted or interrupted by oxygen, or phenyl or naphthyl which are unsubstituted or substituted by C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl, sulfo or a halogenotriazinylamino radical which is unsubstituted or further substituted, or the radical —N(R9)—Y3 is morpholino, and
• K1 is a radical of the formula 82
• in which
• R12 is hydroxyl or amino,
• R13 is methyl or carboxyl,
• (R14)0-3 is 0 to 3 identical or different substituents from the group consisting of C1-C4alkyl, C1-C4alkoxy, halogen, carboxyl and sulfo,
• R15 and R17 are C1-C4alkyl and
• R16 is cyano, carbamoyl or sulfomethyl.
