The invention relates to liquid dye preparations based on metallised dye formulations devoid of sulfonic acid groups and to the use thereof, in particular for producing aqueous dye baths, in particular for leather spray-dyeing. The inventive liquid dye preparations are characterised in that, in addition to a metallised dye formulation A, they comprise a mixture of at least two types of organic solvents and, optionally, water and the solvent mixture substantially comprises i) at least one type of first solvent of following defined general formula (I) R-(O-A)<SUB>k</SUB>-OH, whose water solubility is greater than 100 g/l at a temperature of 25 °C, and ii) at least one second type of organic solvent which contains at least one oxygen atom and whose water solubility is less than 100g/l at a temperature of 25 °C. |
