Abstract

In this study, sensitizing dye was prepared by the reaction of 2-methyl-3-sulfopropyl-4,5-naphthothiazolium(inner salt) with triethyl orthobenzoate in the presence of triethylamine. The product was identified by using various analytical tools such as elemental analyzer, IR spectrophotometer, UV-Vis spectrophotometer, $^1H-NMR$ spectrometer, TGA and DSC. Therefore, it was concluded that 9-phenyl-3,3'-bis(3-sulfopropyl)-4,5,4',5'-naphthothiazolo carbocyanine triethyl ammonium salt can be used as red-sensitizing dye for the spectral sensitization of photographic emulsion.
