Description
The invention relates to new reactive dyestuffs, their preparation and their use.
Reactive dyestuffs are disclosed, for example, in EP-A-97 119. However, the reactive dyestuffs mentioned there still have disadvantages, for example in the fastness properties.
The present invention relates to reactive dyestuffs of the formula (1) ##STR3## in which D denotes the radical of an organic dyestuff,
R, R.sub.1 and R.sub.2, independently of one another, denote hydrogen or substituted or unsubstituted C.sub.1-4 -alkyl,
A denotes a substituted or unsubstituted aliphatic, aromatic or aromatic-aliphatic bridging member,
Pym denotes the radicals ##STR4## X denotes Cl, F n denotes 1 or 2.
Particularly preferred reactive dyestuffs have the following formulae (1a) and (1b) ##STR5## in which D, R, R.sub.1, R.sub.2, A, X and n have the abovementioned meaning.
The radical D is in particular the radical of a sulpho-containing organic dyestuff from the mono- or polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarboximide series.
1 or 2 bireactive fluorotriazinylfluoropyrimidine groupings can be bound to the dyestuff radical D in formula (1). If the dyestuff 2 contains groupings of this type (where n is 2), they are independent of one another and can thus be identical or different with respect to the radicals R, R.sub.1, R.sub.2 or A.
The radical D in formula (1) can be substituted in the usual manner and contains in particular one or more sulpho groups. Examples of further substituents on the radical D are: alkyl groups having 1 to 4 carbon atoms, such as methyl, ethyl, propyl, isopropyl and butyl, alkoxy groups having 1 to 4 carbon atoms, such as methoxy, ethoxy, propoxy, isopropoxy and butoxy, acylamino groups having 1 to 6 carbon atoms, such as acetylamino and propionylamino, benzoylamino, amino, alkylamino having 1 to 4 carbon atoms, phenylamino, alkoxycarbonyl having 1 to 4 carbon atoms in the alkoxy radical, nitro, cyano, trifluoromethyl, halogen, such as fluorine, chlorine and bromine, sulphamoyl, carbamoyl, ureido, hydroxyl, carboxyl, sulphomethyl and sulpho. Those reactive dyestuffs in which D is the radical of an azo dyestuff contain as substituents in particular methyl, ethyl, methoxy, benzoylamino, amino, acetylamino, ureido, sulphomethyl, hydroxyl, carboxyl, halogen and sulpho.
A suitable alkyl radical for R, R.sub.1 and R.sub.2 in formula (1) is a straight-chain or branched alkyl radical which may also be substituted, for example by halogen, sulphato, carboxyl, hydroxyl, cyano or sulpho. Examples of R are: methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec.-butyl, tert.-butyl, .beta.-chloroethyl, .beta.-hydroxyethyl, .beta.-hydroxybutyl, .beta.-cyanoethyl, .beta.-sulphatoethyl, carboxymethyl and sulphomethyl. Preferred groups R.sub.1 and R.sub.2 are: hydrogen, methyl, ethyl, .beta.-hydroxyethyl and .beta.-sulphatoethyl.
A is preferably an alkylene, arylene or aralkyl radical. The term aliphatic bridging member also includes cycloaliphatic radicals. Thus, A can be a long (for example having 10 or more carbon atoms) or relatively short, straight-chain or branched alkylene radical; in particular, an alkylene radical having 2 to 6 carbon atoms is suitable, for example ethylene, propylene, butylene, hexylene or cyclohexylene. As an arylene radical, A is, for example, a naphthylene radical, the radical of a diphenyl or stilbene or in particular a phenylene radical. The radical A can contain further substituents, for example halogen atoms, such as fluorine, chlorine and bromine, alkyl groups having 1 to 4 carbon atoms, such as methyl, ethyl and propyl, alkoxy groups having 1 to 4 carbon atoms, such as methoxy, ethoxy, propyloxy and isopropyloxy, carboxyl, hydroxyl or sulpho. A is preferably C.sub.2-6 -alkylene or substituted or unsubstituted phenylene. Preference is given to the ethylene, propylene, phenylene and sulphophenylene radical.

The reactive dyestuffs of the formula (1) are preferably prepared by condensing an organic dyestuff of the formula ##STR10## or a dyestuff precursor,
2,4,6-trifluoro-s-triazine or 2,4,6-trichloro-s-triazine, a compound of the formula ##STR11## and 2,4,6-trifluoropyrimidine or 4,6-difluoro-5-chloropyrimidine with one another, in which D, R, R.sub.1, R.sub.2 and A have the meanings given in the abovementioned formulae under formula (1) and, if dyestuff precursors are used, by converting the intermediates obtained into the desired final dyestuffs.
In the process described above, the individual process steps can be carried out in a different order, if desired some of them may also be carried out simultaneously. For this, various process variants are possible. In general, the reaction is carried out stepwise in succession.
Which of the possible process variants gives the best results or under which special conditions, for example at which condensation temperature, it is most advantageous to carry out the reaction depends on the structure of the starting materials.
Important process variants are characterised in that:
1. an organic dyestuff of the formula (5) is condensed with 2,4,6-trifluoro-s-triazine or 2,4,6-trichloro-s-triazine, furthermore a compound of the formula (6) is condensed with 2,4,6-trifluoropyrimidine or 4,6-difluoro-5-chloropyrimidine, and both intermediates are condensed with one another;
2. an organic dyestuff of the formula (5) is condensed with 2,4,6-trifluoro-s-triazine or 2,4,6-trichloro-2-triazine, the primary condensation product is condensed with a compound of the formula (6), and the secondary condensation product obtained is condensed with 2,4,6-trifluoropyrimidine or 4,6-difluoro-5-chloropyrimidine;
3. a compound of the formula (6) is condensed with 2,4,6-trifluoropyrimidine or 4,6-difluoro-5-chloropyrimidine, the primary condensation product is condensed with 2,4,6-trifluoro-s-triazine or 2,4,6-trichloro-s-triazine, and the resulting intermediate is condensed with an organic dyestuff of the formula (5);
4. 2,4,6-trifluoro-s-triazine or 2,4,6-trichloro-s-triazine is condensed with a compound of the formula (6), the primary condensation product is condensed with an organic dyestuff of the formula (5), and the secondary condensation product obtained is condensed in a last step with 2,4,6-trifluoropyrimidine or 4,6-difluoro-5-chloropyrimidine.
The condensation reactions of organic dyestuffs (5), dyestuff precursors and diamines (6) with 2,4,6-trifluoro-s-triazine, 2,4,6-trichloro-s-triazine, 2,4,6-trifluoropyrimidine or 4,6-difluoro-5-chloropyrimidine or their primary condensation products are carried out by known processes, preferably in aqueous or aqueous-organic media in the presence of acid-binding agents.
The formulae given are those of the free acids. The preparation in general gives the salts, in particular the alkali metal salts such as sodium salts, potassium salts or lithium salts. The dyestuffs can also be used as concentrated solutions.
The dyestuffs according to the invention are highly suitable for the dyeing and printing of natural and synthetic OH-- or amido-containing materials, in particular those made of cellulose and polyamides. They are particularly suitable for the dyeing of cellulose materials by the exhaust and cold pad-batch methods, and for the printing of cotton and staple viscose.

EXAMPLE 122
23.6 g of 7-amino-1,3-naphthalenedisulphonic acid monosodium salt were stirred in 150 ml of water/30 g of ice and 20 ml of concentrated hydrochloric acid, and 17 ml of an aqueous sodium nitrite solution (300 g of NaNO.sub.2 /l) were added dropwise at 5.degree. to 10.degree. C. After stirring at 5.degree. to 10.degree. C. for one hour, excess nitrous acid was removed using sulphamic acid.
This cream-coloured suspension was metered into a neutral solution of the coupling component prepared from 13.5 g of N-(3-aminophenyl)-acetamide hydrochloride, 50 ml of water, 50 g of ice and about 30 ml of a 10% strength aqueous lithium hydroxide solution over a period of 30 minutes. During this addition, the pH of the reaction mixture was kept constant at 6.0 to 6.5 using 20% strength aqueous potassium bicarbonate solution. If possible, the temperature should not exceed 10.degree. C. After addition had been completed, stirring was continued for 30 minutes, during which the pH was further kept constant.
15.2 g of 2,4-diaminobenzenesulphonic acid monosodium salt were stirred in 100 ml of water and dissolved at pH 6 using 10% strength lithium hydroxide solution. The solution was heated to 40.degree. C., and 12 g of 5-chloro-4,6-difluoropyrimidine were added. During this condensation reaction, the pH was kept constant at 5.8 to 6.2 using lithium hydroxide solution. After 2 hours at 40.degree. C., hardly any more change in pH could be observed, and condensation was complete according to HPLC analysis. The precipitated lithium fluoride was separated off by filtration. The mixture was then cooled to 0.degree. C. with about 200 g of ice and reacted at this temperature with 10 g of trifluoro-s-triazine. The pH of the second condensation was kept constant between 6.0 and 6.5 by simultaneously metering in 10% strength lithium hydroxide solution. After 15 minutes at 0.degree. to 2.degree. C., the reaction was complete.
The warm red-brown coupling solution of 8.degree. C. prepared above was metered into this colourless condensation solution at 0.degree. C. over a period of 20 minutes, during which the pH was kept constant between 7.0 and 7.2 using 20% sodium carbonate solution. The mixture was heated to 25.degree. C. at a constant pH of 7.0 to 7.2 over a period of 3 hours. After an additional stirring phase of one hour, the reaction was complete. The dyestuff solution was clarified in order to separate off insoluble components, such as lithium fluoride, and salted out with 50 g of sodium chloride. The precipitated dyestuff was filtered off with suction and dried, giving 61 g of an orange-red powder (.lambda..sub.max =406 nm (H.sub.2 O)), which has the structure ##STR291## and dyes cotton in golden yellow dyeings having excellent fastness properties.
By varying the diazo component D-NH.sub.2, the coupling component containing R.sup.1 and R.sup.2 and the diamino compound, further valuable golden yellow reactive dyestuffs of the formula ##STR292## were available in analogy to Example 122, for example those listed in Table 8 below.

EXAMPLE 154
A neutral aqueous solution of 30.9 g of 2-amino-3,6,8-naphthalenetrisulphonic acid disodium salt and 6 g of sodium nitrite in 200 ml of water was metered into a mixture of 40 ml of concentrated hydrochloric acid, 50 g of ice and 50 ml of water over a period of 15 minutes. After stirring at 5.degree. to 10.degree. C. for another 30 minutes, diazotisation was complete. The nitrite excess was removed using sulphamic acid.
This suspension was added to a neutral suspension of the coupling component prepared from 13.5 g of N-(3-aminophenyl)-urea and 100 ml of water over a period of 30 minutes. During this addition, the pH of the reaction mixture was kept constant at 6.0 to 6.5 using 20% strength aqueous potassium bicarbonate solution. If possible, the temperature should not exceed 15.degree. C. After addition had been completed, stirring was continued for 15 minutes, during which the pH of the orange-red solution was further kept constant.
Ice was added to this red-brown coupling solution until a temperature of 0.degree. C. was reached. 12 g of cyanuric fluoride was swiftly added and the pH was simultaneously kept constant at 6.0 to 6.2 by addition of a 20% strength potassium bicarbonate solution. Condensation was complete after 10 minutes. The pH was brought to 5.8 with a few drops of hydrochloric acid, and a solution of 5.8 g of 1,2-diaminopropane in 10 ml of water which was likewise brought to a pH of 5.8 with hydrochloric acid was added to this solution. The red reaction mixture was then heated to 20.degree. C. over a period of 2 hours, during which the pH was maintained at 5.8 to 5.9 with potassium bicarbonate solution. For a short period, this resulted in a solution from which, during an additional stirring phase of one hour, an orange-red precipitate was formed at a pH of 6.0 to 6.1. This dyestuff intermediate was filtered off with suction, and the isolated moist paste was stirred in 200 ml of water at pH 6.0. 12 g of 5-chloro-4,6-difluoropyrimidine were then added, the mixture was heated to 45.degree. C. and condensed at pH 7.5 to 8.0. pH control was carried out by means of sodium carbonate solution. Condensation was complete after about 2 hours. The dyestuff solution was filtered until clear, and the dyestuff was salted out with 25 g of common salt. Filtering off with suction and drying gave 58 g of an orange-red powder (.lambda..sub.max =428 nm (H.sub.2 O)), which has the structure ##STR355## and dyes cotton in reddish yellow hues.

30 g of the dyestuff base of the formula ##STR413## were added to this solution at 0.degree. C. and pH 6.0 to 6.2, and the pH was then kept constant at 7.0 with 20% strength sodium carbonate solution. The mixture was heated to 25.degree. C. at pH 7.0 to 7.2 over a period of 3 hours. The dyestuff solution was clarified by filtration, and 50 g of sodium chloride were added. The mixture was stirred for 1 hour, and the precipitated dyestuff was isolated by filtering it off with suction.
Drying and milling gave about 60 g of a yellow powder (.lambda..sub.max =424 nm (H.sub.2 O)) which has the structure ##STR414## and dyes cotton in brilliant greenish yellow shades.

EXAMPLE 357
23.6 g of 7-amino-1,3-naphthalenedisulphonic acid monosodium salt were stirred in 150 ml of water/30 g of ice and 20 ml of concentrated hydrochloric acid, and 17 ml of an aqueous sodium nitrite solution (300 g of NaNO.sub.2 /l) were added dropwise at 5.degree. to 10.degree. C. After stirring at 5.degree. to 10.degree. C. for one hour, excess nitrous acid was removed using sulphamic acid.
This cream-coloured suspension was metered into a nuetral solution of the coupling component prepared from 13.5 g of N-(3-aminophenyl)-acetamide hydrochloride, 50 ml of water, 50 g of ice and about 30 ml of a 10% strength aqueous lithium hydroxide solution over a period of 30 minutes. During this addition, the pH of the reaction mixture is kept constant at 6.0 to 6.5 using 20% strength aqueous potassium bicarbonate solution. If possible, the temperature should not exceed 10.degree. C. After addition had been completed, stirring was continued for 30 minutes, during which the pH was further kept constant.
15.2 g of 2,4-diaminobenzenesulphonic acid monosodium salt were stirred in 100 ml of water and dissolved at pH 6 using 10% strength lithium hydroxide solution. The solution was heated to 40.degree. C., and 12 g of 2,4,6-trifluoropyrimidine were added. During this condensation reaction, the pH was kept constant at 5.8 to 6.2 using lithium hydroxide solution. After 2 hours at 40.degree. C., hardly any more change in pH could be observed, and condensation was complete according to HPLC analysis. The precipitated lithium fluoride was separated off by filtration. The mixture was then cooled to 0.degree. C. with about 200 g of ice and reacted at this temperature with 10 g of trifluoro-s-triazine. The pH of the second condensation was kept constant between 6.0 and 6.5 by simultaneously metering in 10% strength lithium hydroxide solution. After 15 minutes at 0.degree. to 2.degree. C., the reaction was complete.
The warm red-brown coupling solution of 8.degree. C. prepared above was metered into this colourless condensation solution at 0.degree. C. over a period of 20 minutes, during which the pH was kept constant between 7.0 and 7.2 using 20% sodium carbonate solution. The mixture was heated to 25.degree. C. at a constant pH of 7.0 to 7.2 over a period of 3 hours. After an additional stirring phase of one hour, the reaction was complete. The dyestuff solution was clarified, in order to separate off insoluble components, such as lithium fluoride, and salted out with 50 g of sodium chloride. The precipitated dyestuff was filtered off with suction and dried, giving 61 g of an orange-red powder (.lambda..sub.max =406 nm (H.sub.2 O)), which has the structure ##STR756## and dyes cotton in golden yellow dyeings having excellent fastness properties.
By varying the diazo component D--NH.sub.2, the coupling component containing R.sup.1 and R.sup.2 and the diamino compound, further valuable golden yellow reactive dyestuffs of the formula ##STR757## were available in analogy to Example 357, for example those listed in Table 21 below.

EXAMPLE 389
A neutral aqueous solution of 30.9 g of 2-amino-3,6,8-naphthalenetrisulphonic acid disodium salt and 6 g of sodium nitrite in 200 ml of water was metered into a mixture of 40 ml of concentrated hydrochloric acid, 50 g of ice and 50 ml of water over a period of 15 minutes. After stirring at 5.degree. to 10.degree. C. for another 30 minutes, diazotisation was complete. The nitrite excess was removed using sulphamic acid.
This suspension was added to a neutral suspension of the coupling component prepared from 13.5 g of N-(3-aminophenyl)-urea and 100 ml of water over a period of 30 minutes. During this addition, the pH of the reaction mixture was kept constant at 6.0 to 6.5 using 20% strength aqueous potassium bicarbonate solution. If possible, the temperature should not exceed 15.degree. C. After addition had been completed, stirring was continued for 15 minutes, during which the pH of the orange-red solution was further kept constant.
Ice was added to this red-brown coupling solution until a temperature of 0.degree. C. was reached. 12 g of cyanuric fluoride was swiftly added and the pH was simultaneously kept constant at 6.0 to 6.2 by addition of a 20% strength potassium bicarbonate solution. Condensation was complete after 10 minutes. The pH was brought to 5.8 with a few drops of hydrochloric acid, and a solution of 5.8 g of 1,2-diaminopropane in 10 ml of water which was likewise brought to a pH of 5.8 with hydrochloric acid was added to this solution. The red reaction mixture was then heated to 20.degree. C. over a period of 2 hours, during which the pH was maintained at 5.8 to 5.9 with potassium bicarbonate solution. For a short period, this resulted in a solution from which, during an additional stirring phase of one hour, an orange-red precipitate was formed at a pH of 6.0 to 6.1. This dyestuff intermediate was filtered off with suction, and the isolated moist paste was stirred in 200 ml of water at pH 6.0. 12 g of 2,4,6-trifluoropyrimidine were added, the mixture was heated to 45.degree.

30 g of the dyestuff base of the formula ##STR878## were added to this solution at 0.degree. C. and pH 6.0 to 6.2, and the pH was then kept constant at 7.0 with 20% strength sodium carbonate solution. The mixture was heated to 25.degree. C. at pH 7.0 to 7.2 over a period of 3 hours. The dyestuff solution was clarified by filtration, and 50 g of sodium chloride were added. The mixture was stirred for 1 hour, and the precipitated dyestuff was isolated by filtering it off with suction.
