    • A process for dyeing or printing organic fibrous material made e.g. of polyamide, polyester or polyacrylonitrile, and also of cellulose, said process comprising the use of a dyeing or printing assistant which contains a quaternary ammonium salt. The salt is a reaction product of a copolymer of maleic anhydride and ethylene, propylene or styrene, with a N,N-disubstituted n-alkylenediamine, a homopolymer of a vinylpyridine, or a quaternized copolymer of a vinylpyridine and styrene. The reaction product, the homopolymer, and the copolymer are quaternized with e.g. benzyl chloride. The ammonium salt can also be a homopolymer of a vinylbenzyl chloride which is quaternized with a tertiary monoamine. The fibrous material dyed or printed with e.g. direct or disperse dyes or with cationic dyes has excellent levelness, good penetration of the dye, and good wetfastness properties. It is also possible to obtain multi-shade effects by printing the material patchwise with a reserve paste and then dyeing it.
    • 用于染色或印刷有机纤维材料的方法, 的聚酰胺,聚酯或聚丙烯腈,以及纤维素,所述方法包括使用含有季铵盐的染色或印刷助剂。 该盐是马来酸酐与乙烯,丙烯或苯乙烯的共聚物与N,N-二取代的正构烷基二胺,乙烯基吡啶的均聚物或乙烯基吡啶和苯乙烯的季铵化共聚物的反应产物。 反应产物,均聚物和共聚物用例如季铵化。 苄基氯。 铵盐也可以是乙烯基苄基氯的均聚物,其与叔单胺季铵化。 用例如染色或印刷的纤维材料。 直接或分散染料或阳离子染料具有优异的水平度,良好的染料渗透性和良好的耐湿性能。 也可以通过用保留的糊剂贴片印刷材料然后染色来获得多色效果。
