Abstract: Blue-, red- and/or yellow-dyeing dye mixtures are new. Blue-, red- and/or yellow-dyeing dye mixtures are new. The blue mixture comprises at least one dye of formula (I) and (II). The red mixture comprises at least one dye of formula (III) and (IV). The yellow mixture comprises at least one dye of formula (V) and (VI).

Independent claims are included for the following: (1) preparation of the blue-dyeing dye mixture involving either mechanically mixing the individual dyes; or reacting a compound of formula (XVI) with 1,3,5-trichlorotriazine to form a compound of formula (XVII) and further with a mixture of compounds of formulae H-V 1and H-V 2, and optionally adding further dyes of formula (I), (II) and (VII) to the reaction solution; (2) preparation of the red-dyeing dye mixture involving mixing a diazo component of formula (X) and phenylamine (substituted by -SO 2-Y 3), being conjointly diazotized and coupled onto the coupling component of either 6-amino-4-hydroxy-naphthalene-2-sulfonic acid, sodium salt of 6-amino-4-hydroxy-naphthalene-2-sulfonic acid or potassium salt of 6-amino-4-hydroxy-naphthalene-2-sulfonic acid, and optionally the reaction solution has further dyes of formula (III), (IV) and (VIII) added to it; and (3) preparation of the yellow-dyeing dye mixture involving mixing a diazo component of a compound of formula (XIII) with a diazo component of a compound of formula D 1-NH 2, being conjointly diazotized and coupled onto the coupling component of 5-methyl-2-phenyl-2H-pyrazol-3-ol (substituted by R 7, R 8or -SO 2-Y 4), and optionally the reaction solution has further dyes of formulae (V), (VI) and (IX) added to it in the desired ratio.

Provided that when D 2comprises a fiber-reactive radical then W additionally represent -C(O)-phenyl.
