Synthesis and physical performance of indole and benzimidazole cyanine dyes

Nine indole and benzimidazole cyanine dyes, used as green-sensitizing dyes in photographic emulsions, are synthesized. The compounds are characterized from mass spectrometric and NMR spectroscopic data, and elemental analysis. FAB mass spectrometry proved to be an efficient method for determining the structure of the compounds. From UV-VIS data of the compounds the sensitizing properties of the cyanine dyes are predicted. The reflection spectrum of Gs2-9 coated in photographic emulsions showed J-aggregation behaviour at λ = 560 nm. Unsymmetric benzimidazole-indole cyanine dyes showed good to excellent green sensitizing properties in photographic emulsions, whereas symmetric indole cyanine dyes showed heavy residual colour and no sensitizing properties.

COLORING COMPOSITION, COLORING COMPOSITION FOR COLOR FILTER, AND COLOR FILTER

PROBLEM TO BE SOLVED: To provide a coloring composition using a salt-forming compound, which is soluble in a solvent and can be used as a bright red dye, a coloring composition for a color filter, which is excellent in brightness, heat resistance, and a contrast ratio when used for a color filter, and a color filter having no generation of foreign substances on a coating film. SOLUTION: The coloring composition comprises a salt-forming compound of a cationic cyanine dye represented by general formula (1-1), and an organic solvent. In the formula, A1 and A2 each independently represent -CR12(R13)- or -S-; R1 to R11 each independently represent H, a substituted or unsubstituted alkyl group or the like; R12 and R13 each independently represent a substituted or unsubstituted alkyl group or the like; and Anion- represents a specific sulfate anion.
