Definitions
- the present invention relates to stable aqueous colorant compositions containing at least one anionic dye and at least one pigment and a polyanionic thickener.
- the invention furthermore relates to the use of these colorant compositions for dyeing leather and a process for dyeing leather using the colorant compositions.
- Aqueous colorant compositions e.g. Colorant liquors for leather dyeing, which contain pigments and anionic dyes, have been known for a long time. These dye liquors are usually produced by mixing solid or liquid pigment and dye preparations with water immediately before the leather is dyed. Such aqueous colorant compositions are described, for example, in EP-B1-0 377 409 and EP-A2-0 344 555.
- the disadvantage of this method is that an additional mixing process must take place before each coloring. This mixing process requires complex metering devices and harbors the risk of varying colorant compositions and thus poorly reproducible dyeing results.
- finished aqueous mixtures of water, suspended pigments and anionic dyes were made.
- the use of these colorant compositions is made more difficult by the fact that the aqueous pigment suspensions are not stable in storage.

- Preferred thickeners are aqueous dispersions of copolymers of ethyl acrylate, acrylic acid and methacrylic acid, in particular in the form of their ammonium salts. These thickeners show their greatest thickening potential at pH values above pH 7.5. In the uncharged state, i.e. at pH values between 2 and 3, however, the preferred thickeners have a low viscosity of approximately 1 to 10 mPa-s (at 23 ° C.).
