LIQUID DIRECT DYE FORMULATIONS

摘要

The invention relates to aqueous liquid formulations containing 5 to 30 percent by weight of a dye composition that comprises 25 to 85 percent by weight of direct brown 44, 15 to 75 percent by weight of direct yellow 11 and/or a dye obtained by reducing or thermally treating direct yellow 11, 0 to 15 percent by weight of one or several direct blue dyes, and 0 to 10 percent by weight of one or several direct red dyes, the percentages being relative to the dye composition, 0.5 to 15 percent by weight of one or several alkylamines, the one, two, or three alkyl radicals of which can be substituted by one or two hydroxyl groups and/or amino groups and/or be interrupted by one or two oxygen atoms having an ether function, said percentages being in relation to the total weight of the aqueous liquid formulation, the Na concentration of the liquid formulation not exceeding 0.3 percent by weight. Also disclosed is the use of the inventive aqueous liquid formulations for dyeing cellulose material, especially paper.
