    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.
