Dye mixtures containing 1-amino-4-(3-acetamidophenylamino)-anthraquinone-2-sulfonic acid dye(s) (I) and other 1-amino-4-(3-alkanoylaminophenylamino)-anthraquinone-2-sulfonic acid dye(s) (II) are new. Dye mixtures containing 1-amino-4-(3-acetamidophenylamino)-anthraquinone-2-sulfonic acid dye(s) of formula (I) and other 1-amino-4-(3-alkanoylaminophenylamino)-anthraquinone-2-sulfonic acid dye(s) of formula (II) are new. R1, R3 = H, 1-4C alkyl or 1-4C alkoxy; R2, R4 = H or 1-4C alkyl; and R5 = 2-6C alkyl, optionally with oxygen in the chain. provided that R1 is not methyl if R2-R4 = H and R5 = ethyl. |
