The new compounds of formula I are worked up as dyeing preparations by known methods, for example by grinding in the presence of dispersing agents and/or fillers. The ground mixtures are vacuum or injection dried if dry preparations are desired. The preparations are added to a suitable volume of water for exhaust dyeing, pad dyeing and printing at long or short liquor ratio.
From aqueous dispersion the dyes build up powerfully on synthetic and regenerated organic fibres, both in the loose form and as yarn or textiles. They are especially suitable for dyeing and printing polyester, cellulose acetate, cellulose triacetate and polyamide fibres and textiles, and can also be applied to polyolefin fibres. The known dyeing and printing methods are used, for instance the process described in French Pat. No. 1,445,371.
The dyeings obtained have good fastness in a comprehensive range of properties, the fastness to light and to thermofixation, sublimation and pleating being notably good. They are very fast to wet treatments such as washing, water, sea water, perspiration, solvents, especially dry cleaning liquor, lubricants, and to rubbing, cross dyeing, ozone, gas fumes and chlorine. The dyeings are stable to pre-cure and post-cure permanent press finishing and to soil release finishes. They show good stability to reducing action in the dyeing of textiles containing wool and reserve wool and cotton. The dyeings are dischargeable.
This invention therefore serves the purpose, inter alia, of supplying the textile industry with new, superior dyes for dyeing the synthetic fibre and regenerated fibre textiles which are being produced on an ever growing scale, and with which a prime consideration is to have dyes which are applicable by the rationalized continuous and high-temperature dyeing processes in use today.
In the following Examples the parts are by weight and the temperatures in degrees centigrade.





EXAMPLE 1
At a temperature near to 70.degree. 7 parts of sodium nitrite are added to 155 parts of concentrated sulfuric acid, followed at 15.degree. by 26.2 parts 2-bromo-4,6-dinitroamino-benzene. The solution is stirred for 2 hours at 15.degree.-20.degree. and the diazonium salt solution thus formed is cooled to about 0.degree. and, at this temperature, combined with a solution of 5 parts of urea and 29.4 parts 1-methoxypropionylamino-3-N,N-diethylamino-4-ethoxybenzene in 100 parts of glacial acetic acid. The coupling reaction is brought to a close by addition of concentrated sodium acetate solution until the pH of the reaction mixture is about 4. The dye settles out and is filtered, washed with water until free of acid, and dried.
Applied to polyester fibres or textiles, the thus obtained dye of the formula ##STR11## gives brilliant greenish blue shades of great depth which have very good fastness properties.
EXAMPLE 2
At a temperature not higher than 70.degree. 7 parts of sodium nitrite are added to 155 parts of concentrated sulphuric acid, followed at 15.degree. by 24.2 parts of 2-amino-3-bromo-5-nitrobenzonitrile. The solution is stirred for 2 hours at 15.degree.-20.degree. and the diazonium salt solution thus formed is combined with a solution of 2 parts of urea and 25 parts of 1-N,N-diethylamino-3-(3'-methoxypropionyl)-anilide in 100 parts of glacial acetic acid. After the addition of 500 parts of ice-water the reaction solution is stirred for a further 2 hours, on which the dye settles out. It is filtered, washed with water until free of acid, and dried.
Applied to polyester fibres or textiles, this dye gives brilliant blue shades of great depth which have very good fastness properties.
Further dyes of Formula I which can be produced by analogy with the foregoing Examples are specified in the table below.

APPLICATION EXAMPLE
A mixture of 7 parts of the dye produced as in the foregoing Example 2, 4 parts of sodium dinaphthylmethane disulphonate, 4 parts of sodium cetyl sulphate and 5 parts of anhydrous sodium sulphate is ground in a ball mill for 48 hours to give a fine powder. One part of the powder is dispersed in a little water and the dispersion run through a sieve into a bath of 4000 parts of water containing 2 parts of sodium lauryl sulphate.
100 Parts of a scoured polyester fabric are entered into this dyebath (goods to liquor ratio 1:40) at 40.degree.-50.degree., after which 20 parts of an emulsion of a chlorinated benzene in water are added. The bath is raised slowly to 100.degree. and the fabric dyed for 1-2 hours at 95.degree.-100.degree.. On removal it is rinsed, soaped, rinsed and dried. A level blue dyeing of good depth is obtained which is outstandingly fast to light, washing, water, sea water, perspiration, sublimation, gas fumes, thermofixation, pleating, cross dyeing and permanent press finishing.
Formulae of representative dyestuffs of the foregoing Examples are as follows: ##STR16##
