Process for the preparation of fiber-reactive dyestuffs

A process for the preparation of a fiber-reactive dye mixture of a phthalocyanine dyestuff of the formula (1) ##STR11## and an azo dyestuff of the formula (2)

• (Y--O.sub.2 S).sub.m -(X).sub.n -A-N=N-K (2)
• (each in the form of an acid or as a salt), which comprises reacting a phthalocyanine sulfochloride which in the form of the free acid corresponds to the formula (3) ##STR12## with an aromatic amine of the formula (4)
• H.sub.2 N-A-(X).sub.n -(SO.sub.2 --Y).sub.m ( 4)
• as such or--simultaneously or in any order--in conjunction with an amine of the formula (v) ##STR13## in water or in an organo-aqueous or in an organic solvent at a pH value of from about 4 to about 8 and at a temperature of from about -10.degree. C. to about 100.degree. C., in the presence of an acid binding agent, and subsequently diazotizing unreacted amine of the formula (4) and coupling said diazotized amine with a coupling component of the formula (6)
• H-K (6),
• wherein:
• Pc is a metal-free or metal-containing phthalocyanine, which is unsubstituted except by substituents as indicated in formula (1) which are arranged in the 3- or 4-position of the carbocyclic aromatic nuclei of the phthalocyanine skeleton, or substituted additionally by substituents as indicated in formula (1) which are arranged in the 3- or 4-positions of the carbocyclic aromatic nuclei of the phthalocyanine, or by phenyl or halogen,
• A is phenylene or naphthylene which is unsubstituted or substituted by substituents selected from the group consisting of hydroxy, lower alkyl, lower alkoxy, sulfo, carboxy, halogen, nitro, phenylamino, lower alkanoylamine, benzoylamino, phenylsulfonylamino, phenylamino, benzoylamino and phenylsulfonylamino, which are substituted by lower alkyl, lower alkoxy and/or halogen;
• X is the group --CH.sub.2 -- or --N(CH.sub.3)--;
• Y is vinyl, .beta.-sulfatoethyl or .beta.-hydroxyethyl;
• R.sub.1 and R.sub.2 are identical or different and each is hydrogen, unsubstituted or substituted alkyl, or unsubstituted or substituted phenyl or
• R.sub.1 and R.sub.2 form a ring together with the nitrogen atom;
• m is the number 1 or 2;
• n is the number 0 or 1;
• a, b and c are identical or different and each is a whole or fractional number of from 1 to 4, the sum of (a+b+c) is a whole or fractional number of 6 at a maximum;
• p is a whole or fractional number of from 0 to 3,
• q is a whole or fractional number of from 1 to 4, the sum of (p+q) is a whole or fractional number of 4 at a maximum, and
• K is the radical of a pyrazolone, an aminopyrazole, a pyridone or of a methylene carboxylic acid arylamide coupling component.
