Water-soluble fiber-reactive dyes, containing an amino-substituted 5-triazine ring with a fiber-reactive group of the vinylsulfone series

Description

DESCRIPTION
The invention relates to the field of fiber-reactive dyes.
The practice of dyeing with reactive dyes has in recent years led to increased expectations of the quality of the dyeing and the economics of the dyeing process. Consequently, there continues to be a demand for new reactive dyes with improved properties, not only improved fastness properties but also a high degree of fixation on the dyed material. For instance, European Patent Specification No. 0 076 782 B1 discloses fiber-reactive dyes which contain a triazine radical to which two fiber-reactive radicals of the vinyl sulfone series are each attached via an ethyleneamino group. Even so, it is an object of the present invention to provide new, improved reactive dyes which in particular are capable of dyeing cotton in all shades and are highly suitable for use in exhaust methods, in cold pad-batch methods and in printing, and, what is more, are very readily dischargeable.
This object is achieved by the present invention through discovery of water-soluble dyes which contain one or more, such as two or three, groups Z of the general formula (1) ##STR5## In this formula:
R.sup..alpha. is hydrogen or alkyl of 1 to 4 carbon atoms, such as ethyl, n-propyl or n-butyl, or in particular methyl, but preferably hydrogen,
R.sup..beta. is hydrogen or alkyl of 1 to 4 carbon atoms, such as ethyl, n-propyl or n-butyl, or in particular methyl, but preferably hydrogen,
R is hydrogen or sulfo, preferably hydrogen,
Y is vinyl or a group of the general formula --CH.sub.2 --CH.sub.2 --X, in which X is a substituent which is eliminatable as an anion, in particular by means of an alkali, to form a vinyl group,
the --SO.sub.2 --Y group is preferably meta or para to the ethylene group,
W is hydroxy, N-morpholino, N-piperidinyl, N-pyrrolidinyl or a group of the generalfformula (2) ##STR6## where
G is hydrogen or alkyl of 1 to 6 carbon atoms, preferably 1 to 4 carbon atoms, such as ethyl, n-propyl or n-butyl or in particular methyl, preferably hydrogen, and
Q is a group of the general formula (2a), (2b), (2c) or (2d) ##STR7##
--(CH.sub.2).sub.t --R.sup.a ( 2b)
--(CH.sub.2).sub.t --O--(CH.sub.2).sub.w --R.sup..alpha. ( 2c)
--(CH.sub.2).sub.t --R.sup.b ( 2d)
where
R.sup.a is a group of the general formula --SO.sub.2 --Y, where Y is as defined above, or sulfo,
R.sup.b is hydrogen, alkoxy of 1 to 4 carbon atoms, such as ethoxy or in particular methoxy, sulfo, hydroxy, carboxy or chlorine,
R.sup.c is hydrogen, alkyl of 1 to 4 carbon atoms, such as ethyl or in particular methyl, or alkoxy of 1 to 4 carbon atoms, such as ethoxy or in particular methoxy,
t is from 2 to 6, preferably 2 or 3, and
w is from 1 to 6, preferably 2 or 3, or
W is a radical of the formula (2e)
--A--(CH.sub.2).sub.r --R.sup.a ( 2e)
where
R.sup.a is as defined above,
r is zero, 1 or 2, preferably 2, and
A is a radical of the general formula ##STR8## Preferably, W is a radical of the general formula (2f) ##STR9## where G, R.sup.b and Y are each as defined or in particular preferred herebefore or hereinafter.
Novel dyes which contain one or more groupings of the formula (1) are preferably those of the general formula (3) ##STR10## where:
F is the radical of a sulfo- and/or carboxy-containing dye which may contain a complexed heavy metal ion, such as copper, nickel, cobalt or chromium, for example the radical of a dye of the phthalocyanine, anthraquinone, formazan or azo series, but preferably a sulfo-containing dye of the azo series, in particular the radical of a sulfo-containing monoazo or disazo dye,
n is 1 or 2, preferably 1, and
R, R.sup..alpha., R.sup..beta., W and Y are each as defined for the formula (1).
Preference is given to dyes of the general formula (3) which contain from 1 to 6 sulfo groups in total. The dye radicals F may further contain customary fiber-reactive groups.
Water-soluble dyes, such as those which contain the radical F, with an amino group --NHR.sup..alpha. from which the dyes which contain groupings of the general formula (1) are derived, have been repeatedly described in the literature, for example in the previously cited European Patent Specification No. 0 076 782, in European Patent Application Publications Nos. 0 070 806A, 070 808A, 0 212 264A, 0 076 782A and 0 144 766A, and also in Venkataraman, The Chemistry of Synthetic Dyes, New York, London, 1972, volume VI, pages 213-297. Particularly useful dyes of this series are water-soluble azo dyes which do not contain any heavy metal, in particular those which contain sulfo and/or carboxy groups, preferably sulfo groups, in particular sulfo-containing monoazo and disazo dyes, and metal complex dyes such as sulfo-containing 1:1 copper complex monoazo and disazo dyes.
Substituents X eliminatable as anions are for example: chlorine, sulfato, thiosulfato, phosphato, alkylsulfonyloxy of 1 to 4 carbon atoms, such as methylsulfonyloxy, alkanoyloxy of 2 to 5 carbon atoms, such as acetyloxy, and sulfobenzoyloxy; of these, sulfato and phosphato, especially sulfato, are preferred.
Important azo dyes conforming to the general formula (3) are those in which F is a radical of a dye of the benzene-azo-naphthol, the benzene-azo-1-phenyl-5-pyrazolone, the benzene-azo-benzene, the naphthalene-azo-benzene, the benzene-azo-aminonaphthalene, the naphthalene-azo-naphthalena, the naphthalene-azo-1-phenyl-5-pyrazolone, the benzene-azo-pyridone or of the naphthalene-azo-pyridone series, of which again the sulfo-containing dyes are preferred.
Such azo dyes of the general formula (3) are for example dyes of the general formulae (4a), (4b) and (4c) ##STR11## in which
D is in each case the radical of a diazo component which in the case of the two D radicals may be identical to or different from the other,
E is the bivalent radical of a diazotizable compound capable of coupling,

Preferably, R.sup.2 is hydrogen, methyl, methoxy, bromine, chlorine, carboxy or sulfo and R.sup.3 is hydrogen, methyl, methoxy, chlorine, carboxy, sulfo or acetylamino.
The labels "sulfo", "carboxy", "phosphato", "thiosulfato" and "sulfato" include not only the acid form of these substituents but also their salt form. Accordingly, sulfo is a group of the general formula --SO.sub.3 M, carboxy is a group of the general formula --COOM, phosphato is a group of the general formula --OPO.sub.3 M.sub.2, thiosulfato is a group of the general formula --S--SO.sub.3 M and sulfato is a group of the general formula --OSO.sub.3 M, wherein in each case M is as defined above.

The aromatic amine diazo components may also contain other fiber-reactive groups of the type repeatedly described in the literature, for example in addition to the abovementioned fiber-reactive group of the vinyl sulfone series other reactive groups of the aliphatic series, for example .beta.-bromoacryloylamino, .alpha.,.beta.-dibromopropionylamino, .beta.-(phenylsulfonyl)propionylamino, .beta.-(methylsulfonyl)propionylamino, .beta.-chloropropionylamino-2,2,3,3-tetrafluorocyclobutane-1-carbonylamino, N-(.beta.-sulfatoethylsulfonyl)-N-methylamino or -N-ethylamino, or N-(vinylsulfonyl)-N-methylamino or -N-ethylamino, and also fiber-reactive groups of the heterocyclic series, for example of the diazine, triazine, pyridine, pyrimidine, pyridazine, thiazine, oxazine, quinoline, phthalazine or phenanthridine series. Such heterocyclic groups are described for example on pages 9 to 16 of German Offenlegungsschrift No. 3,503,746, which groups are bonded to D via an amino group of the above-defined formula --N(R.sup..alpha.)--. Heterocyclic fiber-reactive groups are preferably which are substituted by halogen, such as 2,6-difluoro-5-chloropyrimidin-4-ylamino, 2-fluoro-5-chloropyrimidin-4-ylamino, 2-fluoro-5-chloro-6-methylpyrimidin-4-ylamino, 2-fluoro-5,6-dichloropyrimidin-4-ylamino, 6-fluoro-2,5-dichloropyrimidin-4-ylamino or in particular 2-chloro- or 2-fluoro-1,3,5-triazin-6-ylamino groups with the amino radical of the above-defined formula --N(R.sup..alpha.)--, to which a triazinyl radical may be substituted in the 4-position by low alkoxy or phenoxy or by primary, secondary or tertiary amino whose substituents may be selected from the following groups:

For instance, monoazo and disazo dyes conforming to the general formula (3) can be synthesized by reacting their diazo and coupling components, which each or both contain a fiber-reactive group of the general formula (1), by the usual method of diazotization and coupling. If disazo dyes are to be synthesized, the diazo or coupling component may already contain the second azo group.

Such diazo and coupling components are for example the compounds conforming to the general formulae (5), (6), (7), (8), (9), (10), (11), (13) and (14) described at the beginning.
The diazotization and coupling reactions are carried out in a conventional manner; for instance the diazotization in general at a temperature between -5.degree. C. and +15.degree.

C., preferably between -5.degree. C. and +30.degree. C., and at a pH between 4.5 and 8.0, preferably between 5 and 7. The reaction of the halotriazinylamino compounds with an amino compound of the general formula (23) or (24) or H-W.sup.1 is carried out for example at a temperature of between -10.degree. C. and +60.degree. C., preferably between 0.degree. and 5.degree. C., and at a pH between 3 and 8, preferably between 4 and 7.5, although care must be taken to ensure that the fiber-reactive group is not damaged in the weakly alkaline range.

C. and 25.degree. C. and the phosphation at a temperature between 5.degree. and 30.degree. C.
The starting dyes which contain one or more .beta.-hydroxyethylsulfonyl groups are synthesizable similarly to the above directions for the preparation of the dye according to the invention by either using corresponding dye intermediates which contain this or these .beta.-hydroxyethylsulfonyl groups or reacting an amino dye of the general formula (23) and an amino compound of the general formula (24) and optionally an amino compound of the general formula H-W.sup.1 of the above meaning, in each of which however Y is .beta.-hydroxyethyl, with a cyanuric halide under the above reaction conditions. In the latter case, in which the starting compound (24) or its halotriazinyl derivatives (26) and (27) contain .beta.-hydroxyethylsulfonyl group(s) as --SO.sub.2 --Y, the condensation reaction can also be carried out at a more strongly alkaline pH, for example at a pH between 8 and 10.

The dyes according to the invention, in particular those conforming to the general formula (3), are suitable for use as fiber-reactive dyes for dyeing and printing hydroxy-containing fibers, in particular cotton, but also synthetic or natural polyamide fibers such as wool. Suitable dyeing methods are the known dyeing and printing methods for fiber-reactive dyes, in particular those for fiber-reactive dyes which possess a combination of fiber-reactive groups of the fluorotriazine and vinyl sulfone series. Such methods have been repeatedly described in the general literature and in the patent literature, for example in European Patent Application Publication No. 0 196 536A1. In particular, the dyes according to the invention can be applied with advantage by the exhaust method at 40.degree. to 80.degree. C. and by the cold pad-batch method. Application is possible over a wide temperature range, and the dyes are notable for good depth of colour and a high degree of fixation; the dyeings and prints prepared therefrom have high fastness properties.

The Examples which follow serve to illustrate the invention. Parts and percentages are by weight, unless otherwise stated. Parts by weight bear the same relation to parts by volume as the kilogram to the liter.
The compounds described in the Examples by means of formulae are shown in the form of the free acids; in general, they are prepared and isolated in the form of their sodium or potassium salts and used for dyeing in the form of their salts. It is similarly possible to use the free acid starting compounds and components mentioned in the examples which follow, in particular the Table Examples, in the synthesis in that free acid form or in the form of their salts, preferably alkali metal salts.
