The radicals R and R are alkyl and alkylene radicals which may be straight chain or branched, substituted or unsubstituted. Examples of suitable substituents are halogen atoms or low molecular alkyl radicals with l to 4 carbon atoms. Particularly suitable radicals R and R are the hydrocarbon radicals of' corresponding saturated and unsaturated fatty acids or fatty alcohols, e.g., the radicals of caprylic, capric, lauric, myristic, palmitic, stearic, arachidic, behenic, decenoic, dodecenoic, tetradecenoic, hexydecenoic or oleic acid. It is also possible to use radicals of polyunsaturated fatty acids, for example those of linoleic or linolenic acid.
M is an organic or preferably an inorganic cation. Preferred inorganic cations are those of the alkali metal group, e.g., the lithium, but especially sodium and potassium cation, but also the ammonium ion. As organic cations there are used, for example, derivatives of organic amines which contain at least one protonised nitrogen atom, primary, secondary and tertiary monoand polyamines which are optionally further substituted being suitable.

If, for example, B and B are benzene radicals, R and R may be phenyl or aralkyl radicals with up to 10 carbon atoms; but if they are naphthalene radicals, then R, and R should preferably not be aromatic radicals.
Particular interest attaches to the compounds of the formulae (7) 9 6) n 2n+l or C H COO Also suitable are compounds of the formulae 3 and of the formulae so (3 n 3 1 C H OCO C H CO so (9 M 9 c n oco so 3 M1 (+3 und c n ocmw so 3 9 M G9 In the formulae (7) to 14), R represents a hydrogen atom or a methyl or methoxy group, M represents sodium, potassium or protonised mono-, dior triethanolamine and n represents a number from 11 to 18.
In the componds of the formulae (7) to (9) and (1 1), the S0 M group is usually in B-position to the CO0 and OCO group and R is preferably a hydrogen atom. A substitution in the orthoor meta-position is also possible.
The manufacture of the anionic compounds used for the present invention is known and is carried out e.g. by reacting fatty acid derivatives with corresponding phenolic or naphtholic compounds, or by reacting fatty alcohols with benzene or naphthalene derivatives which contain carboxylic acid groups or substituents which can be converted into such groups.
The amount of anionic assistant in the dyeing preparations is for example 0.1 to 5 percent, and preferably 1 to 3 percent, relative to the fibre material to be dyed.
The dyeing is carried out in liquors which have pH values of about 3 to 6, preferably 3.5 to 5. The pH values are adjusted with mineral acids, or preferably with lower organic acids, such as formic, acetic, oxalic or tartaric acid. Furthermore, it is advantageous to dye in buffered liquors, i.e., mixtures of acids with corresponding salts.
As basic dyes the dyestuff preparation according to the invention preferably contains the customary salts and metal halide (preferably zinc chloride) double salts of the known cationic dyes, in particular the methine or azomethine dyes, which contain the indolinium, pyrazolium, imidazolium, triazolium, tetrazolium, oxdiazolium, thiodiazolium, oxazolium, thiazolium, pyridinium, pyrimidinium, or pyrazinium ring. The cited heterocycles can be substituted and/or condensed with aromatic rings. Also possible are cationic dyes of the diphenylmethane, triphenylmethane, oxazine and triazine series, and finally, dye salts of the arylazole and anthraquinone series with external onium group.
It is also possible to use dyestuff mixtures. The amount of dye is about 0.5 to 5 percent, relative to the fibre material to be dyed.
The dyeing preparations can contain further assistants which are conventionally used in dyeing, for example non-ionic surface active compounds, in particular addition products of ethylene oxide and alcohols, phenols and amines, or organic solvents, in particular ethylene glycol monoethyl ether or thiodiethylene glycol, as well as ethylene carbonate.
The dyeing process according to the invention can be applied to all acrylic or modacrylic textile materials, i.e., to all textile materials whose fibres are composed of homopolymers or copolymers in which acrylonitrile predominates. Copolymers are for example those of acrylonitrile and other vinyl compounds, such as acrylic esters, acrylic amides, vinyl pyridine, vinyl chloride, vinylidene chloride, copolymers of dicyanoethylene and vinyl acetate, as well as of acrylonitrile block copolymers.
The fibre material can be dyed according to the invention in any desired form, for example as flocks, spinning cables, worsted tops, yarn, woven or knitted fabrics. The textile material is dyed by means of known processes, preferably by the exhaust method, in dyeing machines and vessels suitable for the purpose, both under normal pressure and in sealed vessels under pressure.
The dyeing preparation according to the invention is appropriately manufactured by making the basic dye into a paste with the amount of acid or buffer salt acid to be used, pouring hot water on to the paste and then treating the resulting dye bath with the anionic assistants as well as, optionally, further assistants conventionally used in dyeing. The preparations possess good stability.
The textile material is put into this liquor, which can have a temperature of from 50 to C, and then optionally the temperature of the liquor is increased in order to dye in the temperature range of from 80 to C, preferably at the boiling point of the liquor.
The liquor ratios are about 1:10 to 1:50, preferably 1:20 to 1:40. The dyed material is subsequently washed and dried in the customary manner.
Dyeings of excellent levelness and good fastness properties are obtained with the process according to the invention for dyeing textile material made from polyacrylonitrile accompanied by the use of anionic assistants. In particular, when dyeing with a mixture of different basic dyes no selectively dyed patches of fibre are obtained, i.e., the anionic assistants display a good retardation and levelling action without the occurrence of blocking effects. Furthermore, no alteration of shade occurs during the dyeing process. And, in addition, good exhaustion of the liquor is observed. In the process according to the invention, and with the use of the dyeing preparations according to the invention, it is possible to dye light and dark shades levelly and fast independently of the rates of absorption of the dyes or the properties of the substrates, e.g., their chemical composition.
The following Examples will serve to illustrate the invention, but without being in any way limitative thereof. The parts and percentages are by weight unless otherwise stated.
