Abstract
Dye mixtures comprising 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 for dyeing or printing cellulose-containing fibre materials, while at the same time exhibiting good build-up behaviour, and yield dyeings of deep shade having good fastness properties.
Claims15
