Spectral Sensitization and Photographic Characteristics of 9-Phenyl-5,5'-Diphenyl-3,3'-Bis(3-sulfopropyl)Benzoxazolo Carbocyanine Triethyl Ammonium Set

9-Phenyl-5,5'-Diphenyl-3,3'-Bis(3-sulfopropyl)Benzoxazolo Carbocyanine Triethyl Ammonium Salt의 분광증감과 사진특성

In this paper, we describe a study on the relationship between spectral sensitization and photographic characteristics of color paper. The photographic emulsion used in this study is a green-sensitizing emulsion. U.V maximum absorption peak value of 9-phenyl-5,5'-diphenyl-3,3'-bis(3-sulfopropyl)benzoxazolo carbocyanine triethyl ammonium salt was observed 507nm, and wedge spectrograms maximum peak value of color paper added dye to photographic emulsion was shown 553nm. As compared with the absorption peak of the dye in methanol solution, the sensitizing peaks of 9-phenyl-5,5'-diphenyl-3,3'-bis(3-sulfopropyl)benzoxazolo carbocyanine triethyl ammonium salt have red shifts of 46nm. The photographic characteristics of green-sensitizing emulsion were obtained contrast(2.6), speed(48-57), fog(0.08). Therefore, benzoxazolo carbocyanine dye is of industrial importance as green-sensitizing dye in the spectral sensitization of photographic emulsion.
