The synthesis, characterization, genotoxicity and light fastness of thio-and oxopyrimidine based bisazomethin pigments prepared from a series of nonmutaenic benzidine congeners is reported. Whereas bisazomethine pigments based on benzidine and 3,3'-dimethylbenzidine were mutagenic in both the Ames assay and the prival modification of the Ames assay, incorporation of bulky (>C₂) alkyl and alkoxy groups in the 3,3'-positions of the benzidine moiety gave nonmutagenic bisazomethine pigments. ⓒ 2001 Elsevier Science Ltd.
