    Abstract: A process for producing a liquid formulation of salts of sulfonated azo dyes by coupling an at least equimolar amount of diazotized aminoarylsulfonic acids I H2N—Ar—SO3H  (I), where Ar is phenylene (which may be monosubstituted by sulfo) or naphthylene (which may be mono- or disubstituted by sulfo and/or monosubstituted by hydroxyl) onto the coupling product of an unsubstituted or methyl-substituted phenylenediamine with itself comprises dissolving the azo dye in a basic medium and then subjecting the solution to a nanofiltration.

    Abstract: An aqueous liquid formulation (F1) comprises (wt.%): a dye composition (C1) (5 - 25); saturated, cyclic or acyclic water-soluble amine (1 - 15); and urea (1 - 30), where the total amount of water-soluble amine and urea does not exceed 40 wt.%. An aqueous liquid formulation (F1) comprises (wt.%): a dye composition (C1) (5 - 25); saturated, cyclic or acyclic water-soluble amine (1 - 15); and urea (1 - 30), where the total amount of water-soluble amine and urea does not exceed 40 wt.%. (C1) Comprises (wt.%): a dye (70 - 95) obtainable by reduction or thermal treatment of Direct Yellow 11, blue direct dye (1 -30) and optionally red direct dye (1 - 20). The water-soluble amine comprises a primary, secondary or tertiary amino group and at least one further functional group selected from primary, secondary and tertiary amino groups, OH groups and ether groups.
