Beschreibung
Zusammenfassung:	The present invention relates to an aqueous formulation of dye mixtures, comprising at least one anionic dye, at least one cationic dye and/or an acid dye derived from a cationic structural unit and, optionally, at least one formulation assistant, a process for their preparation and the use thereof for dyeing natural or synthetic fibres, especially paper or paperboard. La présente invention porte sur une formulation aqueuse de mélanges de colorants, cette formulation comprenant au moins un colorant anionique, au moins un colorant cationique et/ou un colorant acide dérivé d'un motif structurel cationique et, éventuellement, au moins un auxiliaire de formulation. L'invention porte également sur un procédé de préparation de ces mélanges de colorants et sur leur utilisation dans la coloration de fibres naturelles ou synthétiques, notamment le papier ou le carton.
