Process for the dyeing of natural and synthetic polyamide fibre material from organic solvents by the exhaustion process with difficultly water-soluble dye salts of anionic dyestuffs, the dye liquors applicable for this purpose, as well as the polyamide fibre material dyed, said process being characterised in that the fibre material is treated with the solution or suspension of at least one difficultly water-soluble dye salt consisting of the anionic radical of an anionic dyestuff and an organic cation in a liquid, non-water-miscible, organic solvent boiling above 50 DEG C which contains, relative to the weight of the material being treated, an addition of 0.1 to 100% of water and, optionally, up to 5% of an acid. |
