The present invention relates to advantageous processes for the manufacture of organic pigments and their precursors. The invention particularly relates to reactions carried out in an 'All In One Reactor'® (Draiswerke GmbH, Germany), a kneader like the TurbuKneader® of the same company, a paddle dryer like the Turbudry® of the same company or a related system and thereby submitting the reaction mixtures to enhanced driving power as expressed by a Froude number>1, the reaction mixture being caused to react in high concentrations at elevated temperature.

Disclosed are a production process of a dye polymer having a dye content of from 1 to 50 wt %, and the dye polymer and its use. The production process includes subjecting an addition-polymerizable monomer to living radical polymerization by using, as a polymerization initiator, a dye having a polymerization initiating group enabling the living radical polymerization. The dye polymer and a composition of the dye polymer and a pigment are useful as good coloring agents for various products or articles. The colored products or articles are high in transparency, and are provided with high added value. The dye polymer can also be used as a dispersant for pigments, thereby making it possible to afford pigment dispersions excellent in dispersion properties and dispersion stability.
Verfahren zur Herstellung von Verbindungen der Formel I
worin die Symbole X, A, m und n die in Patentanspruch 1 angegebene Bedeutung haben, dadurch gekennzeichnet, dass man die Verbindung der Formel II
in alleiniger Gegenwart von einer mindestens stöchiometischen Menge Chlorsulfonylisocyanat zur Verbindung der Formel 111 umsetzt
und diese mittels eines Carbonsäureamides in die Verbindung der Formel I überführt.
Die Verbindungen der Formel eignen sich als Ausgangsstoffe zur Herstellung von Pigmenten der Isoindolinonreihe.
一种制备式 I 化合物的工艺
其中符号 X、A、m 和 n 具有权利要求 1 中给出的含义,其特征在于,式 II 的化合物
仅在一定量的氯磺酰异氰酸酯存在下进行反应,得到式 111 的化合物
并通过羧酸酰胺将其转化为式 I 的化合物。
式中化合物可作为生产异吲哚啉酮系列颜料的起始原料。
