    • The triphendioxazine compounds of the general formula (I) in which the rings labeled A in positions 1,2-, 2,3- or 3,4- and 8,9-, 9,10- or 10,11- carry a linearly or angularly fused heterocyclic ring containing at least one nitrogen atom which is substituted or unsubstituted, with the proviso that compounds with only unsubstituted nitrogen atoms and symmetrically disubstituted compounds with C1-2alkyl and unsubstituted phenyl substituents are excluded, are outstanding pigments and are notable over the closest comparable pigments in particular for better migration, light and solvent fastnesses, better heat stability and enhanced colouring power and also better dispersibility and capability to be brought into pigment form. The invention also relates to a process for preparing these triphendioxazine compounds which is characterized by a cyclization step conducted in the presence of manganese dioxide and concentrated sulphuric acid.
    • 通式(I)的三苯并二恶嗪化合物其中1,2-,2,3-或3,4-和8,9-,9,10-或10,11位上标记为A的环具有线性 或含有至少一个被取代或未取代的氮原子的角稠合杂环,条件是不包括仅具有未取代的氮原子和具有C 1-2烷基和未被取代的苯基取代基的对称二取代化合物的化合物是优异的颜料,并且在 特别是用于更好的迁移,轻和耐溶剂牢度,更好的热稳定性和增强的着色能力以及更好的分散性和能够进入颜料形式的最接近的可比颜料。本发明还涉及一种制备这些三苯并二恶嗪化合物的方法,其特征在于 在二氧化锰和浓硫酸存在下进行环化步骤。
