Abstract: of the disclosure: The compounds obtained by bis-diazotizing 3,8-diamino-phenathridone-(10) and coupling it onto one or a mixture of coupling components having no solubilizing groups are ?igments of high tinctorial strength and fastness to migration, heat, light and chemicals.

Abstract: 2,5-Bis-(4'-aminophenyl)-1,3,4-oxadiazoles which are chlorinated in the phenyl nuclei are obtained by condensing hydrazine or a hydrazine yielding agent with equal or different chlorinated benzoic acids or acylating acid derivatives having in para-position to the acid group an amino group or a group capable of being transformed into the amino group, and, thereafter, effecting ring closure of the so-obtained bis-hydrazide to yield the oxadiazole. The products are bis-diazo components, especially for pigments having a very high tinctorial strength, clear and pure shades, a good fastness to light, to heat and to solvents.
