Abstract: 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.

Abstract: Method for the trichromatic dyeing or printing of synthetic polyamide fiber material, wherein at least one red reactive dye of formula is used together with at least one of the yellow or orange reactive dyes of formulae and at least one blue reactive dye of formula in which formulae the variables are as defined in claim 1, which method is distinguished by a uniform color build-up and a very good combinability.
