Abstract

The invention relates to a method for producing a solution containing a dye and to a method for dyeing a substrate, characterised by the following steps: a. transferring the dye from biological material into an aqueous medium, b. precipitating the dye from the aqueous medium by the addition of a suitable precipitant, wherein at least a part of the precipitant forms a part of the dye precipitate, c. separating the dye precipitate from the aqueous medium and d. transferring the dye from the dye precipitate into an aqueous medium by adding a release agent and dyeing the substrate with an aqueous solution by releasing the dye from the dye precipitate by adding a release agent to the aqueous solution, characterised in that the release agent is a complexing agent, selected from the group of polycarboxylates, polycarboxylic acids, amino polycarboxylic acids, such as NTA or EDTA, oxalate, gluconate, citrate, phosphate, polyphosphate or combinations thereof.
