摘要： 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.
