The process for the preparation of reactive dyes of formula (1) comprises coupling and condensing, in suitable sequence, l-amino-8-hydroxynaphthalene-3,6-disulfonic acid or l-amino-8-hydroxynaphthalene-4,6-disulfonic acid, benzenediazo components (A) and (B), 2,4,6-tri-chloro-s-triazine and amino compounds (Z^) and/or (Z^)* As the individual process steps referred to above can be carried out • in varying sequence and, if desired, in some cases can be carried out simultaneously, different variants of the process are possible. In general, the reaction is carried out stepwise in succession, with the s sequence of the simple reactions between the individual reactants conveniently being chosen in accordance with the special conditions. It is known to carry cut coupling first in acidic medium in the o-amino position and then in alkaline medium in the o-hydroxy position 5 since l-amino-8-naphtholsulfonic acids which are first coupled in alkaline medium (o-hydroxyazo dyes) can not be further coupled to give disazo dyes.
Important process variants comprise: 1) condensing 2 mol of 2,4,6-trichloro-s-triazine with 1 mol of a 10 disazo compound of the formula h2'\ «? Fa /"z < >—; ; ?—< > (6) XS03H H03S/ V N./ XS03H H03S/ and condensing the resultant diprimary condensation product in the molar ratio of 1:2 with an equimolar mixture of amines (Z^) and (Z^) to give a reactive dye of formula (4); 15 2) condensing 2 mol of 2,4,6-trichloro-s-triazine with 2 mol of an amine (Z^) or (Z^) and condensing the resultant primary condensation product with 1 mol of a disazo compound of formula (6) to give a reactive dye of formula (4), (Z^ = Z^); 3) condensing 2 mol of 2,4,6-trichloro-s-triazine with 1 mol of a 20 disazo compound of formula (6) and condensing the resultant diprimary condensation product with 2 mol of an amine (Z^) or (Z^) to give a reactive dye of formula (4), (Z^ = Z^)J 4) condensing 2 mol of 2,4,6-trichloro-s-triazine with 2 mol of l,3-phenylenediamine-4-sulfonic acid, condensing the primary conden- 25 sation product with 2 mol of an amine ^ ) or (Z^), diazotising the 7 resultant secondary condensation product and then effecting coupling, first in strongly acidic solution and then in neutral solution, with l-amino-S-hydroxynaphthalene-3,6-disulfonic acid to give a reactive dye of formula (4), (Z^ = Z^); It 5 5) condensing 2 mol of 2,4,6-trichloro-s-triazine with 2 mol of 1,3-phenylencdia:nine-4-sulfonic acid, diazotising the primary conden-S3tion product and then effecting coupling, first in strongly acidic solution and then in neutral solution, with l-amino-8-hydroxynaphtha-lene-3,6-aisulfonic acid, and condensing the resultant disazo dye with 10 2 col of an amine (Z^) or (Z^) to give a reactive dye of formula (4), (2i * V- The procedure is the same when using l-amino-8-hydroxynaphthalene-4,6-disulfonic acid as coupling component or where using other diazo components, e.g. 1,4-phenylenediamine-2-sulfonic acid. 15 The disazo compounds of formula (6) are prepared by coupling 1,8-amino-naphthol-3,6-disulfonic acid with 2 equivalents of diazotised 5-nitraniline-2-sulfonic acid (acidic and alkaline coupling) and subsequently reducing the nitro groups or by coupling 1,8-amino-naphthol-3,6-disulfonic acid with 2 equivalents of diazotised 5-acetyl-20 aminoaniline-2-sulfonic acid and subsequently saponifying the acetyl-amino groups. In practice, the acid coupling is carried out by adding a solution of l-amino-8-hydroxynaphthalene-3,6-disulfonic acid to the strongly acidic diazo suspension. The subsequent alkaline coup-ling is effected in known manner in weakly alkaline medium. It is 25 preferred to carry out the coupling of the monoazo compound with a # further equivalent of the diazo components in alkaline bicarbonate solution. The saponification of the two acetylamino groups after completion of the alkaline coupling is carried out in known manner with alkaline compositions. It is preferred to carry out the 30 saponification with sodium hydroxide.
It is preferred to carry our the condensation of the 2,4,6-trichloro-s-triazine with the amines (Zj) and/or (2^) and the disazo compound of formula (6) or the diazo components (A; and (B) in aqueous solution or suspension, at low temperature and at a weakly acidic, neutral to weakly alkaline pH value. It is advantageous to neutralise the hydrogen halide set free during the condensation by the continuous addition of aqueous alkali metal hydroxide, carbonate or bicarbonate.

The reactive dyes of formula (1) are suitable for dyeing and printing a very wide range of materials such as silk, leather, wool, polyamide fibres and pclyurethanes, and especially cellulosic fibre materials 25 of all kinds. Examples of such fibre materials are natural cellulose fibres such as cotton, linen and hemp, as well as cellulose and regenerated cellulose. The reactive dyes of the formula (1) are also suitable for dyeing or printing fibres which contain hydroxyl groups 10 and which are components of blended fabrics, e.g. of blends of cotton with polyester or polvamidc fibres.
The dyes of this invention can be applied in different manner to the fibre material and fixed thereon, especially in the fortn of aqueous 5 dye solutions and printing pastes. The reactive dyes of formula (1) are suitable both for the exhaust process and for dyeing by the pad dyeing process, in which the goods arc impregnated with aqueous dye solutions which may also contain salts, and the dyes are fixed after treatment with alkali, or in the presence of alkali, with or without 10 the application of heat. The dyes of this invention are also particu larly suitable for the so-called cold pad-batch method, which comprises applying the dye together with the alkali on the pad and subsequently fixing the dye by snoring the impregnated goods for several hours at room temperature. After fixation the dyeings or prints are 15 thoroughly rinsed with cold and hot water, if necessary with the addition of a compound which acts as a dispersant and piromotes the diffusion of non-fixed dye. The reactive dyes of formula (1) are also suitable for printing, especially on cotton, and for printing nitrogen-containing fibres, e.g. wool, silk or blends containing wool. 20 The reactive dyes of formula (1) are particularly suitable for dyeing by the exhaust process; the degrees of fixation are high and non-fixed dye can be readily washed off.
The dyeings and prints obtained with the dyes of this invention on 25 cellulosic fabrics have excellent tinctorial strength and excellent dye-fibre bond stability both in acidic and in alkaline medium, and they also have good light fastness and very good wetfastness properties such as fastness to washing, water, sea-water, cross-dyeing and perspiration, as well as good fastness to pleating, ironing and 30 rubbing. 11 10 15 The invention is illustrated by the following Examples in which parts and percentages are by weight, unless otheri^ise stated. The ratio of parts by weight to parts by volume is the same as that of kilograms to litres.
The preparation of the tnonoazo or disazo intermediates is not described in all of the following Examples. However, any undisclosed preparation is clearly evident from what has been stated above.
Example 1; 21.5 parts of the disazo dye of the formula are dissolved in 300 parts of ice water to give a neutral solution to which is added, with good stirring, a solution of 11.4 parts of cyanuric chloride in 60 parts of acetone. The temperature increases to 15 to 20°C, while keeping the pH value at 6 to 7 by the dropwise addition of a solution of 1-n sodium hydroxide. When acylation of the two terminal amino groups is complete, 9 parts of N-^>-hydroxyethylanilin2 are added to the dye suspension, the reaction mixture is heated to 40 to 45°C and the pH is kept at 8 by the dropwise addition of a solution of 1-n sodium hydroxide. Amidation is complete after 1 to 2 hours.
The dye is precipitated from the resultant solution by adding 10 % by * volume of sodium chloride, then isolated by filtration and dried in vacuo at 60°C. • The resultant dye of the formula \ /\ V SO^H HO^S' S03H H03S' KOCH.C 2 ■CH CH OH 1 2 dyes cotton by the exhaust process in navy blue shades.
