Abstract:
The invention relates to a method for producing the quaterrylene-3,4:13,14-tetracarboxy diimides of general formula (I), wherein R, R' independently represent hydrogen or optionally substituted C 1 -C 30 alkyl, C 3 -C 8 cycloalkyl or aryl or hetaryl. The inventive method is characterized by reacting the perylene-3,4-dicarboximide of the general formula (IIa) in the presence of a base resistant, high-boiling, organic solvent and an alkali-containing or alkaline earth-containing base with the perylene-3,4-dicarboximide of the general formula (IIb), wherein X represents hydrogen, bromine or chlorine.
Abstract:
Disazo dyes of formula (1) where one of the two symbols X?1 and X2¿ means hydroxy and the other amino, while D?1 and D2¿ means the residue of a disazo component from the aniline series. The invention also relates to sulphonamides as their intermediate producs and to the use of the new dyes for the dyeing of natural or synthetic substrates.
Abstract:
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.
Abstract:
