    Abstract: An inventive blue colorant comprising a chromophore having at least one hydroxy group-terminated polyester chain attached, through a suitable alkylamino linking group (or groups), to the 1- position, the 4- position, or both, of an anthraquinone backbone and having at least one hindering group in a secondary position in relation to said amino linking group is provided. Such colorants exhibit excellent amine/base stability and thermal stability, effective colorations, excellent low extraction rates, high lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain polyurethane substrates, and, most importantly excellent stability in the presence of excess of diisocyanates. The polyester chain or chains can be conveniently tailored to increase the solubility or compatibility in different types of polyurethane resin precursors thereby permitting the introduction of such excellent coloring chromophores within diverse polyurethane media and/or or diverse polyurethane substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such inventive colorants are provided as well as methods for producing such inventive colorants.

    Abstract translation: 本发明的蓝色着色剂包括具有至少一个羟基封端的聚酯链的发色团,其通过合适的烷基氨基连接基团(或基团)连接到蒽醌骨架的1-位置,4-位或二者,并具有 提供了相对于所述氨基连接基团处于二级位置的至少一个受阻基团。 这些着色剂表现出优异的胺/碱稳定性和热稳定性,有效着色,优异的低萃取速率,高耐光性水平,特别是当结合到某些介质中和/或在某些聚氨酯基材的表面上时,最重要的是在存在下优异的稳定性 的过量二异氰酸酯。 可以方便地调整聚酯链或链,以增加不同类型的聚氨酯树脂前体的溶解度或相容性,从而允许在多种聚氨酯介质和/或多种聚氨酯底物内引入这些优异的着色发色团,并提供液体着色剂 方便处理。 提供了包含这种本发明着色剂的组合物和制品以及制备这种本发明着色剂的方法。

    Abstract: Beschrieben wird ein Verfahren zur Herstellung von 1-Aminoanthra­chinonen aus 5-Nitro-1,4,4a,0a-tetrahydroanthrachinon mit einem basischen Reduktionsmittel, wobei die Reaktion unter Druck bei Temperaturen über 100°C in einem wässrig-organischen Medium durchge­führt wird. Es wird sehr reines 1-Aminoanthrachinon erhalten, das u.a. ein wichtiges Farbstoffzwischenprodukt darstellt.
