    摘要: A method of dyeing or printing textile fiber materials, which comprises bringing the fiber material into contact with (a) at least one reactive dye containing at least one anionic group, (b) at least one compound which reduces the ionic character of the anionic group, and (c) at least one nucleophilic compound, yields dyeings or prints having deep hues and very good fastness properties.
