Abstract
Reactive dyes of the formula ##STR1## in which K and Z are as defined in claim 1, are suitable in particular for the dyeing and printing of cellulose-containing fibre material and produce dyeings and prints having good fastness properties in high coloristic yield.
Description

The present invention relates to novel reactive dyes, processes for theft preparation and their use for the dyeing and printing of fibre materials.
The practice of dyeing using reactive dyes has recently led to increased demands on the quality of the dyeings and the economy of the dyeing process. As a result thereof, there is still a need for novel reactive dyes exhibiting improved properties, in particular with respect to application.
For the dyeing of cellulose-containing materials, such as cotton, today's demands are for reactive dyes which have sufficient affinity and whose unfixed portions can, at the same time, be easily washed off. Furthermore, they should exhibit high reactivity and produce, in particular, dyeings having high degrees of fixation. The known dyes do not fulfil these requirements in all their properties.
Accordingly, the object of the present invention is to find novel, improved reactive dyes for the dyeing and printing of cellulose-containing fibre materials which possess the qualities characterized above to a high degree. The novel dyestuffs should be distinguished in particular by high fixation yields and high stability of the fibre-to-dye bond. Furthermore, the dye not fixed on the fibre should be easy to wash off. Moreover, they should produce dyeings having good general fastness properties, for example light and wet fastness properties.
It has been found that by using the novel reactive dyes defined below this object can be largely achieved.
Accordingly, the invention relates to reactive dyes of the formula ##STR2## in which Z is .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.-phosphatoethyl, .beta.-acetyloxyethyl, .beta.-haloethyl or vinyl and K is the radical of a coupling component.

The process for the preparation of the reactive dyes of the formula (1) comprises diazotising diazo components of the formula, ##STR24## in which Z is as defined under formula (1) and coupling the product onto one of the coupling components K and, if desired, carrying out a further conversion reaction, for example again diazotising the intermediate formed after coupling and coupling the product onto a further coupling component from the defined group K and, if desired, further reacting the product or coupling the intermediate onto a further diazo component.
In general, the reaction is carried out stepwise in succession; coupling onto the middle component in the ortho-position relative to the NH.sub.2 group in acidic solution must be carried out first because coupling in the ortho position relative to the OH in neutral or alkaline solution, for example in the case of coupling component K5 in formula (12), if carried out first, could not be followed by coupling in the ortho position relative to the amino group.
Another method is to fast prepare a dye containing a precursor of the reactive radical and convening this precursor afterwards into the end product stage, for example by esterification or an addition reaction.
Moreover, the synthesis can be followed by elimination reactions. For example, reactive dyes of the formula (1) containing sulfatoethylsulfonyl radicals can be treated with dehydrohalogenating agents, such as sodium hydroxide, which convert the sulfatoethylsulfonyl radicals into vinylsulfonyl radicals.
In principle, reactive dyes of the formula (1) of all classes of dyes can be prepared in a manner known per se or analogously to known procedures by starting from precursors or intermediates for dyes containing fibre-reactive radicals according to formula (1a) or by introducing these fibre-reactive radicals into intermediates of dye character suitable for this purpose.
The reactive dyes of the formula (1) are suitable for the dyeing and printing of a wide range of materials, such as silk, leather, wool, polyamide fibres and polyurethanes, and in particular cellulose-containing fibre materials of any kind. Examples of such fibre materials are natural cellulose fibres, such as cotton, linen and hemp, cellulose itself and regenerated cellulose. The reactive dyes of the formula (1) are also suitable for the dyeing or printing of hydroxyl-containing fibres present in blended fabrics, for example of cotton blends with polyester fibres or polyamide fibres.
The dyes according to the invention can be applied to the fibre material in various ways and fixed on the fibre, in particular in the form of aqueous dye solutions and printing pastes. They are not only suitable for the exhaust method but also for dyeing by the padding method and can be used at low dyeing temperatures and require only short steaming times in the pad steam process. The degrees of fixation are high, and the unfixed dye can be easily washed off, the difference between degree of exhaustion and degree of fixation being remarkably small, i.e. the soaping loss being very low. The reactive dyes of the formula (1) are also suitable for printing, in particular on cotton, but also for the printing of nitrogen-containing fibres, for example of wool, silk or wool-containing blended fabrics.
The dyeings and prints obtained with the dyes according to the invention on cellulose fibre materials have a high colour strength and a high stability of the fibre-to-dye bond, not only in the acidic but also in the alkaline range, furthermore good lightfastness and very good wetfastness properties, such as wash, water, seawater, cross-dyeing and perspiration fastness properties, and good pleating fastness, hotpress fastness, rubfastness and in particular chlorine fastness.





The examples which follow serve to illustrate the invention. Temperatures are given in degrees centigrade, parts and percentages are by weight, unless stated otherwise. Parts by weight relate to parts by volume as the kilogram relates to the litre.
The most important process variants are described in the exemplary embodiments.
EXAMPLE 1
A solution of 21.7 g of 2-.beta.-sulfatoethylsulfonyl-5-sulfoaniline in 270 ml of water was diazotised using 30 ml of 5N hydrochloric acid and 15 ml of 3.33N NaNO.sub.2 solution at 0.degree. to 5.degree. C., and a neutral aqueous solution of 14.2 g of 1-(4-sulfophenyl)-3-carboxy-5-pyrazolone was added. By strewing in sodium bicarbonate, the pH was brought to a value of 5 to 6. After coupling was complete, the dye was salted out with potassium chloride and subjected to gentle drying under reduced pressure. It has the formula ##STR25## and dyes cotton in lighffast yellow hues.
EXAMPLE 2
An aqueous suspension of 31.9 parts of 1-amino-3,6-disulfo-8-naphthol is introduced at 5.degree. C. into an aqueous hydrochloric acid solution of the diazonium salt obtained from 37 parts of 2-.beta.-sulfatoethylsulfonyl-5-sulfoaniline, and the coupling reaction is carried out at a pH of between 1 and 2. An aqueous hydrochloric acid suspension of the diazonium salt of a condensation product obtained by reaction of 18.8 parts of 4-sulfo-1,3-phenylenediamine with 18.4 parts of cyanuric chloride at a pH of 2.5 and a temperature of 10.degree. C. is then added. The second coupling reaction is carried out at a pH of between 5 and 6. A solution of 18 parts of 3-sulfoaniline is then added, and the condensation reaction is brought to completion at a pH of between 7 and 9 and a temperature of 20.degree. to 30.degree. C. The batch is then allowed to cool, made neutral, and the resulting azo compound according to the invention is salted out with sodium chloride and isolated in the usual manner.
This gives a black, electrolyte-containing powder of the compound of the formula ##STR26## which exhibits very good fibre-reactive dye properties and dyes, for example, cotton by the dyeing and printing processes customary for fibre-reactive dyes in navy hues having good fastness properties.
EXAMPLE 3
95 parts of cyanuric chloride are reacted in a known manner with 1-amino-8-hydroxynaphthalene-3,6-disulfonic acid in water. A freshly diazotised equivalent solution of 2-.beta.-sulfatoethylsulfonyl-5-sulfoaniline is added to this product, and the pH is brought to a value of 4 to 4.5. After coupling is complete, 1 part of 1-amino-4-.beta.-(.beta.'-chloroethylsulfonyl)ethylaminocarbonylbenzene hydrochloride is added and made to react at a pH of 7 to 7.5 and 35.degree. C. Salting out with KCl gives the dye of the formula ##STR27## which dyes cotton in bright red shades having good fastness properties.
EXAMPLE 4
16 parts of 1-amino-8-hydroxynaphthalene-3,6-disulfonic acid are dissolved in 400 parts of water under neutral conditions. The reaction solution is brought to a pH of 4.5, and 7.0 parts of cyanuric fluoride are added dropwise at 0.degree. to 3.degree. C. with thorough stirring. The hydrogen fluoride released during this addition is neutralised by metered addition of 2N sodium hydroxide solution. When free 1-amino-8-hydroxynaphthalene-3,6-disulfonic acid can no longer be detected, 17 parts of 1-amino-3-.beta.-(.beta.'-chloroethylsuffonyl)ethylaminocarbonylbenzene hydrochloride in 50 parts of water are added. The temperature is allowed to rise to 20.degree. to 25.degree. C. while maintaining the pH of the reaction solution at 4 to 4.5. After condensation is complete, the dye intermediate is coupled at 0.degree. to 10.degree. C. onto 18 parts of diazotised 2-.beta.-sulfatoethylsulfonyl-5-sulfoaniline. At a final pH of 6.5 to 7, the dye of the formula ##STR28## is salted out with sodium chloride, filtered, washed and dried in vacuo. It is a dark red powder and dyes cotton and regenerated cellulose in bluish red hues having good pad, rub and lightfastness properties.
EXAMPLE 5
An aqueous solution of 22 parts of 1-naphthylamino-6-sulfonic acid is added at 0.degree. to 5.degree. C. to an aqueous hydrochloric acid solution of the diazonium salt obtained from 37 parts of 2-.beta.-sulfatoethylsulfonyl-5-sulfoaniline, and the coupling reaction is carried out at a pH of between 2 and 3. The intermediate obtained of the formula ##STR29## is diazotised in the usual manner, and the product is coupled onto 3-acetylaminoaniline at a pH of 5 to 7 and a temperature of between 0.degree. and 10.degree. C. The compound thus formed of the formula ##STR30## is condensed with dibromopropionyl chloride at 0.degree. to 20.degree. C. and a pH of between 5 and 8.
The dye obtained of the formula ##STR31## is salted out with potassium chloride and subjected to gentle drying. It dyes cotton in brown hues having good fastness properties.
Further dyes according to the invention listed in the tables below can be prepared analogously to these examples.
