The compounds according to the invention are surfaceactive products. They have proved particularly valuable as auxiliaries when dyeing, with cationic dyestuffs, fibre materials which can be dyed with cationic dyestuffs,

The dyeing of the fibre materials which can be dyed with cationic dyestuffs can be carried out in the customary manner, by introducing the material to be dyed into an aqueous dyeing liquor, warmed to about 50 60C, which contains the cationic dyestuff, compounds of the formula (I), added salts, such as sodium acetate or sodium sulphate, and also acids, such as acetic acid or formic acid, subsequently raising the temperature of the dyebath to about C over the course ofabout 30 minutes and then keeping the dyebath at this temperature until it is exhausted. It is also possible to pre-treat the material to be dyed, at a temperature of 40 100C, with a liquor which contains the customary salts and acids as well as compounds of the formula (I), but as yet does not contain any dyestuff, to add the dyestuff only at this stage and to carry out the dyeing at 100C. Finally, it is also possible to introduce the material to be dyed directly into the dyebath, heated to about 100C, which contains compounds of the formula (I).

Possible cationic dyestuffs are dyestuffs of the most diverse classes of compounds, for example diphenyl- 5 methane, triphenylmethane and rhodamine dyestuffs, azo or anthraquinone dyestuffs containing onium groups, and also thiazine, oxazine, methine and azomethine dyestuffs such as are described, for example, in Ullmanns Encyclopadie der technischen Chemie (Ullmanns Encyclopedia of Industrial Chemistry), 3rd Edition, l970, Supplementary Volume, page 225.

The requisite amounts of the compounds of the formula (I) to be used according to the invention can be determined easily by preliminary experiments. In general, amounts of approx. 0.25 to 2.5% of these compounds, relative to the weight of the material to be dyed which has been introduced, are employed.

Possible fibre materials which can be dyed with cationic dyestuffs are, for example, those of anionically modified polyesters and polyamides, but especially those of'polyacrylonitrile or copolymers containing acrylonitrile.

Suitable copolymers containing acrylonitrile are, for example, copolymers of acrylonitrile with vinyl chloride, vinylidene chloride, vinyl acetate. vinyl chloroacetate, vinyl alcohol, acrylic and methacrylic acid, acrylic and methacrylic acid esters, allyl chloroacetate or basic vinyl compounds, such as vinylimidazole. vinylbenzimidazole, vinylpyridine, vinylmethylpyridinc l and vinylpyrimidine, provided the proportion of these co-monomers does not exceed 20 per cent by weight.

As examples of quaternary ammonium compounds suitable for the dyeing process, those compounds of the formula (I) in which R, R R R A-CH and X" have the meaning indicated in the table below may be mentioned.
