Abstract
Dye mixtures that comprise at least one dye of formula together with at least one dye from the group of formulae wherein the radicals have the definitions given in the claims, are suitable, with good build-up behaviour, for dyeing or printing cellulose-containing fibre materials, and yield dyeings having a deep shade and good fastness properties.
