    摘要: Alkanediyl bridged benzimidazolo monomethine cyanine dyes are disclosed wherein at least one benzimidazolo nucleus is provided with an electron-withdrawing group. A disclosed preparation of the dyes includes producing an electron-withdrawing group substituted bis(2-nitrophenyl)-2-R.sup.1 -propanediamide, where R.sup.1 is hydrogen or alkyl; converting the nitro groups to primary amine substituents; removing the elements of water to effect ring closure; and thereafter providing the -CR.sup.1 - linked benzimidazole nuclei so formed with an N,N'-alkanediyl bridging group and quaternizing substituents. Dye synthesis is completed by reducing the -CR.sup.1 - linking group to the corresponding methine. The dyes are useful as sensitizers in silver halide emulsions and photographic elements.
