The dyestuffs according to the invention are suitable for dyeing natural and synthetic fibre materials, especially for dyeing polyamide fibres in level, orange to red shades which are of good tinctorial strength and have very good fastness to wet processing and light. They are already taken up well by polyamide fibres in a neutral to weakly acid dyebath. Polyamide fibres are understood, in particular, as those made of synthetic polyamides, such as e-polycaprolactam or condensation products of adipic acid and hexamethylenediamine.
Example 1
4 g of 4-N,N-diethylaminosulphonyl-2,5-dichloroaniline are diazotised in 100 ml of glacial acetic add and 30 ml of concentrated hydrochloric acid at 0 C with 10 ml of an aqueous 10% strength NaNO, solution. The mixture is stirred for a further two hours at 0 C.
5.4 g of N-ethyl-N-(ss-sulphophthalyliminoethyl)-m-toluidine are dissolved in 100 ml of H20 and 20 ml of glacial acetic acid. This solution is allowed to run into the diazonium salt solution described above. The pH is adjusted to about 4 using a saturated solution of sodium acetate. The dyestuff of the formula
which has precipitated is then filtered off and dried at 400C.
N-Ethyl-N-(ss-sulphophthalyliminoethyl)-m-toluidine, which is employed as the coupling component, was obtained as follows.
17.8 g of N-ethyl-N-(ss-aminoethyl)-m-toluidine are heated together with 32 g of sulphophthalic acid to 200 C in the course of 3 hours. After a further hous, the mixture is allowed to cool, the solidified melt is ground and the finely ground product is stirred thoroughly in 200 ml of methanol.
Dyeing Example
0.1 g of the dyestuff obtained according to Example 1 are dissolved in 100 ml of hot water. 5 ml of ammonium acetate solution are added and the mixture is diluted with water to a volume of 500 ml. 10 g of polyamide fibre material is introduced into the dyebath, the bath is heated to the boil in the course of 20 minutes, 4 ml of 10% strength acetic add are added and the bath is kept at the boiling point for 1 hour. The material is then rinsed and dried at 70--800C. A scarlet dyeing is obtained.
Example 2 4.6 g of 2,5-dichloro-+methylsulphonylaminosulphonvlaniline are diazotised in
100 ml of glacial acetic acid and 30 ml of concentrated hydrochloric acid at OC with 10 ml of a 10% strength NaNO2 solution. The mixture is stirred for a further 2 hours.
4.5 g of N-ethyl-N-Gss-phthalyliminoethyl)-m-toluidine are dissolved in 50 ml of glacial acetic acid. This solution is added to the diazonium salt solution described above. The pH is adjusted to about 4 with a saturated solution of sodium acetate. The dyestuff of the formula
which has precipitated is filtered off and dried at about 40 CC.
The dyestuff leads polyamide in a reddish-tinged orange colour shade.
If the procedure of Example 1 or 2 is followed and the compounds listed in the table which follows are employed as the diazo components and as the coupling components, valuable water-soluble dyestuffs which dye polyamide from a weakly acid or neutral bath in the indicated shades are obtained.
