Method for spectrally sensitizing photographic light-sensitive emulsions |
摘要 |
A method of spectrally sensitizing a photographic light-sensitive emulsion where a water-soluble solution, prepared by dissolving a methine dye having at least one water-soluble group in water in the presence of a "Red Shift Compound", as hereinafter defined, is added to a photographic light-sensitive emulsion to provide a photographic light-sensitive emulsion spectrally sensitized with increased sensitizing efficiency and with reduced fog. The disadvantages caused by the use of high organic solvent contents are avoided and photographic light-sensitive emulsions suitable for high-speed coating are obtained.
