摘要： Polyhalocopper phthalocyanine pigments of high color strength are prepared by recrystallizing the finely divided agglomerated crude pigment in a heterogeneous aqueous organic phase at elevated temperatures by a process in which the aqueous organic phase used is a heterogeneous mixture of an aliphatic ketone having a total of 3 to 9 carbon atoms and water. The process gives the pigments in the form of spherical granules which are dust-free or have a low dust content. The pigments give deep, brilliant colorations of pure hues.
