摘要： A process for preparing a black colorant, preferably a black pigment, characterized in that a compound of the Formula (I) is reacted with a compound of the Formula (II) in a molar ratio of 1:2, in the presence of a catalyst which in water at 25 °C has a pK = 4.5. For the definition of R1 to R7, refer to the description; preferably all are H. Likewise claimed are new crystal polymorphs obtainable by this process, and preferably single-phase mixed crystals. Also claimed are synergistic compositions. These compositions exhibit increased light stability in plastics stabilized with basic light stabilizers when they are pigmented with colorants of the invention rather than with known black pigments such as carbon black. The specification also relates, furthermore, to the use of the black colorants of the invention for coloring paints, printing inks and plastics in the mass, and to mulch film, instrument panels, woven fabrics, garden furniture items or elements for the construction industry that are pigmented with said colorants.
摘要翻译：一种制备黑色着色剂，优选黑色颜料的方法，其特征在于使式（I）化合物与摩尔比为1:2的式（II）化合物在催化剂存在下反应其在25℃的水中具有pK = 4.5。关于R1〜R7的定义，请参考说明书; 优选全部为H.同样要求保护的是通过该方法可获得的新晶体多晶型物，优选单相混合晶体。还要求的是协同组合物。当用本发明的着色剂着色时，这些组合物在用碱性光稳定剂稳定的塑料中显示增强的光稳定性，而不是已知的黑色颜料如炭黑。此外，本说明书还涉及本发明的黑色着色剂用于在油漆中着色油漆，印刷油墨和塑料的用途，以及用于建筑行业的膜，仪表板，机织织物，花园家具或元件的覆盖用着色剂着色。
