Abstract
Abstract The invention relates to a dye mixture which contains a dye of the formula ##STR1## wherein Z is hydrogen or methyl, and a dye of the formula ##STR2## Z in the formula (1) being hydrogen when the propionylamino group in the formula (2) is bound in the m-position with respect to the NH group. The dye mixture is suitable for dyeing or printing natural or synthetic polyamide materials, especially in combination with other dyes, and particularly from short liquors. The dye mixture is characterized by generally good properties, in particular by good strike properties and good solubility.
