Abstract: Process for improving the application properties of disazo pigments obtained by coupling bis-diazotized chlorine-substituted 4,4'-diaminobiphenyls with acetoacetylaminobenzenes, which includes adding sulfite ions to the pigment suspension obtained in the coupling and then heating for one half to two hours at 50.degree. to 100.degree. C. The process produces, above all in large scale industrial batches, a product of uniform quality and having acceptable fastness to solvents, overlacquering, migration and bleeding.

Abstract: Diaryl pigments having an excellent stability to heat are obtained by carrying out the coupling of bis-diazotized 3,3'-dichloro-4,4'-diaminobiphenyl with acetoacetanilides in the presence of an added quantity of acetoacetanilides which are monosubstituted or disubstituted in the 3-position or 4-position of the nucleus. As a result of their good heat stability, these pigments are particularly suitable for pigmenting plastics having processing temperatures above 200.degree. C.

Abstract: Azo pigments are obtained by diazotizing a diazotizable aromatic amine without solubilizing groups in anhydrous dipolar aprotic water-miscible solvents with the stoichiometric amount or a small excess of nitrosylsulfuric acid or nitrosyl chloride, coupling the diazonium compound so obtained with a coupling component and isolating the pigment obtained in usual manner. This process is carried out in homogeneous solution and yields azo pigments the advantageous properties of which cannot be achieved by other methods, for example, the excellent purity, grain softness, narrow range of particle size distribution, excellent dispersibility in plastic materials and color lacquers, high gloss and excellent opacity in color lacquers.
