  Object To provide a method for producing a bis-quaternary ammonium salt efficiently and a novel synthetic intermediate thereof. Solution The present invention relates to a method for producing a bis-quaternary ammonium salt represented by a general formula [3] which comprises reacting a disulfonic acid ester represented by a general formula [1] (in the formula, definitions of two R1's and T are as described in Claim 1) with a tertiary amine represented by a general formula [2] (in the formula, definitions of R3 to R5 are as described in Claim 1), and a disulfonic acid ester represented by a general formula [1'] (in the formula, two R16's represent independently a halogen atom or a C1-C3 fluoroalkyl group, and two m's represent independently an integer of 1 to 5).

  目的 提供一种高效生产双季铵盐的方法及其新型合成中间体。 本发明涉及一种生产通式[3]代表的双季铵盐的方法，该方法包括将通式[1]代表的二磺酸酯（式中，两个 R1 和 T 的定义如权利要求 1 所述）与通式[2]代表的叔胺（式中、式中，R3 至 R5 的定义如权利要求 1 所述），以及通式[1']代表的二磺酸酯（式中，两个 R16 独立地代表卤素原子或 C1-C3 氟烷基，两个 m 独立地代表 1 至 5 的整数）。

  The invention relates to the dyeing of human keratin fibres, especially the hair, using anionic direct dyes bearing a particular ammonium or phosphonium counterion of formula (Ia) and/or optical brighteners of formula (Ib) Col (−) m [X + ] n (Ia) Azu (−) m [X + ] n (Ib) in which formulae (Ia) and (Ib): Azu/Col (−) m, R 1 , R 2 , R 3 , R 4 , m and n are as defined in the description. The invention relates to a dye composition comprising an anionic compound of formula (Ia) and/or (Ib), and to a process for dyeing keratin fibres such as the hair, using the said composition. Similarly, the invention relates to novel anionic compounds of formula (Ia) or (Ib) and to the uses thereof for dyeing keratin fibres. This composition makes it possible to obtain chromatic, powerful and particularly fast coloration on keratin fibres and particularly lightening coloration via an optical effect on dark hair.
