Dyestuff mixtures of fiber-reactive azo dyestuffs and their use for dyeing fiber material containing hydroxyl and/or carboxamide groups

摘要

Mixtures of fiber-reactive azo dyestuffs with which black dyeings, including prints, are obtained on fiber materials containing hydroxy and/or carboxamide groups, such as cellulosic fiber materials, wool and synthetic polyamide fibers, are described. These dyestuffs mixtures comprise one or more dyestuffs of the following formulae (1) and (2): <IMAGE> (1) <IMAGE> <IMAGE> (2) <IMAGE>n in the specification.
