Webments based on chlorinated benzene-diazonium salts or biphenyl-bis-diazonium salts and acidic CH coupling components. Industrially produced organic pigments may contain polychlorinated biphenyls (PCBs) as an impurity if certain structural conditions exist in the starting compo nents and because of side reactions, depending on the WebAryl diazonium salts may be reduced to the corresponding hydrazines by mild reducing agents such as sodium bisulfite, stannous chloride or zinc dust. The bisulfite reduction may proceed by an initial sulfur-nitrogen coupling, as shown in the following equation. Ar-N 2(+) X (–) NaHSO 3. Ar-N=N-SO 3 H.
