Definitions

• the compounds (I) are prepared by known processes from unsaturated fatty acids or from mixtures of saturated and unsaturated fatty acids, for example mixtures obtained from natural fats, or from their esters or chlorides and the unsymmetrical dialkylalkylenediamines.
• the amidamines are then again quaternized by known processes using quaternizing agents such as benzyl chloride, methyl, ethyl, butyl chloride, dimethyl and diethyl sulfate and dimethyl methane phosphoric acid.
• quaternizing agents such as benzyl chloride, methyl, ethyl, butyl chloride, dimethyl and diethyl sulfate and dimethyl methane phosphoric acid.
• oleic acid, soy oleic acid Suitable for palm kernel acid, poppy oil acid, sunflower oil acid, rapeseed acid and tallow fatty acid.
• Unsymmetrical alkylated alkylenediamines for example N, N-dimethyl-ethylenediamine, NN-diethylethylenediamine, N, N-dimethyl-propylenediamine and N, N-diethyl-propylenediamine, are to be mentioned as diamines.
• Suitable cationic dyes are dyes of the most varied classes of compounds, for example diphenylmethane, triphenylmethane and rhodamine dyes, azo or anthraquinone dyes containing onium groups, furthermore thiazine, oxazine, methine and azomethine dyes, as described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, 3 Edition 1970, supplement volume p. 225 are described.
• the required amounts of the compounds of formula (I) to be used according to the invention can easily be determined by preliminary tests. In general, amounts of about 0.25 to 2.5%, based on the weight of the dye material used, of these compounds are used.
• Suitable Acrylnitrilmischpolymerisate are for example copolymers of Acyrlnitril with vinyl chloride, vinylidene chloride, vinyl acetate, vinyl chloroacetate, vinyl alcohol, acrylic and methacrylic acid, Acyrl and methacrylic acid esters, allyl or basi - specific vinyl compounds such as vinyl imidazole, Vinylbenzimidazol, vinylpyridine, Vinylmethylpyridin, vinylpyrimidine, the proportion provided that Co-monomers is not more than 20 percent by weight.
• the dyeing of the polyacrylonitrile fiber materials can be carried out in the customary manner in the exhaust process by introducing the material to be dyed into an aqueous dye liquor heated to about 50-85 ° C. which contains the cationic dye, compounds of the formula (I), additions of salts such as sodium acetate or Sodium sulfate, also contains acids such as acetic acid or formic acid, then the temperature of the dyebath is raised to approximately 100 ° C. in the course of about 30 minutes and then the dyebath is kept at this temperature until it is exhausted.
• the material to be dyed can also be pretreated at a temperature of 40-100 ° C.
• fiber materials consisting of polyacrylonitrile or acrylonitrile-containing copolymers or containing such copolymers or copolymers, which can be present in various processing stages, for example as spun tow, sliver, flakes, threads, yarns, woven or knitted fabrics, are excellently uniform and to color in deep tones.
