CA 2628706
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.
Compositions liquides aqueuses qui contiennent 5-30 % en poids d'une composition de colorants comprenant 25-85 % en poids de brun direct 44, 15-75 % en poids de jaune direct 11 et / ou d'un colorant pouvant être obtenu par réduction ou traitement thermique de jaune direct 11, 0-15 % en poids d'un ou plusieurs colorants bleus directs et 0-10 % en poids d'un ou plusieurs colorants rouges directs, par rapport au poids de la composition de colorants, ainsi que 0,5-15 % en poids d'une ou plusieurs alkylamines dont un, deux ou trois radicaux alkyle sont substitués par un ou deux groupes hydroxyle et / ou groupes amino et / ou peuvent être interrompus par un ou deux atomes d'oxygène dans la fonction éther, par rapport au poids total de la composition liquide aqueuse, la teneur en Na de la composition liquide ne dépassant pas 0,3 % en poids. La présente invention concerne également l'utilisation de ces compositions pour colorer de la matière cellulosique, en particulier du papier.
