Abstract: 1393957 Preparing pigments HOECHST AG 7 July 1972 [10 July 1971] 31944/72 Heading C4P Pigments containing the benzothioxanthene nucleus are prepared by reacting a compound containing the 1-(2 1 -aminophenylmercapto)-naphthalene nucleus or the 1-phenylmercapto-8- aminonaphthalene nucleus in a tertiary amine with a compound yielding nitrosyl groups and heating the diazonium compound formed. Compounds yielding nitrosyl groups are nitrososulphuric acid and nitrosyl chloride and the tertiary amines used include pyridine, picoline, quinoline, isoquinoline or mixtures thereof. The starting compounds include 3-(2 1 -amino-phenylmercapto) - benzanthrone and 4 - (2 - aminophenylmercapto)-naphthalic acid anhydride.
