    Abstract: An improvement in the process for dyeing synthetic fibers containing anionic groups, e.g., acrylonitrile copolymers, with basic dyestuffs in chlorohydrocarbon dyebaths containing 0.1-4 percent by weight of water is obtained by utilizing a dyeing auxiliary having the formula WHEREIN R1 and R2, independently of one another are C14-C22-alkyl or C14-C22-alkenyl in which the total of the carbon atoms contained in R1 and R2 is 32-44; R3 is lower alkyl, haloalkyl or hydroxyalkyl; R4 is optionally substituted cycloalkyl, aralkyl or C1-C4-alkyl, or together with R3 forms a 5- or 6-membered heterocycle; and X( ) IS AN ANION.

    Abstract translation: 通过使用具有式WHEREIN R 1和R 2的染色助剂,独立地使用含有0.1-4重量百分比的水的染料用于染色含有阴离子基团的合成纤维(例如丙烯腈共聚物)的氯代烃染料浴中的碱性染料的改进 另一个是C 14 -C 22 - 烷基或C 14 -C 22 - 烯基,其中R1和R2中所含的碳原子总数为32-44; R3是低级烷基,卤代烷基或羟烷基; R 4是任选取代的环烷基,芳烷基或C 1 -C 4烷基,或与R 3一起形成5-或6-元杂环; 和X( - )是AN ANION。
