摘要： A pigment of the formula: ##STR1## wherein each of the rings A, B and C independently is unsubstituted or is substituted by one, two or three radicals which do not confer solubility, or the ring A can additionally carry a fused ring. The novel compounds of the invention are useful as pigments for coloring, printing inks, plastics, and, especially, surface coatings.
