    • A method for spectrally sensitizing silver halide emulsions is disclosed, comprising the step of adding a cyanine dye, which provides a J-band when added to silver halide emulsions, to a silver halide emulsion followed by ripening with such conditions that the relative quantum yield .phi..sub.r of spectral sensitization assumes a value of 1/2 or less of the .phi..sub.r of spectral sensitization obtained when the dye is added to the emulsion under ripening conditions of 40.degree. C. and 20 minutes from the time of addition of the dye to the emulsion until the time of coating the emulsion, and then ripening the silver halide emulsions. In one embodiment of the disclosed method, a heterocyclic compound which contains a mercapto group is added to the emulsion before the addition of the dye in an amount sufficient to increase the .phi..sub.r.
    • 公开了一种用于光敏增感卤化银乳剂的方法,其包括以下步骤:将加入卤化银乳剂时提供J-带的花青染料加入到卤化银乳剂中,然后通过熟化使相对量子产率phi r的光谱增感假定当染料从添加染料时到40℃和20分钟的熟化条件下添加到乳液中时获得的光谱增感的1/2的值。 乳液直到涂布乳液,然后熟化卤化银乳剂。 在所公开的方法的一个实施方案中,在添加染料之前将含有巯基的杂环化合物加入到乳液中,其量足以增加phi。
