  公开（公告）日：2009-09-17

  A non-infrared sensitized low silver photographic element with a non-light sensitive layer, preferably an antihalation layer, containing a diphenylaminocyclopentene heptacyanine benzothiazolium infrared dye where the benzothiazolium groups have electron-withdrawing substituents on the phenyl ring and solubilzed alkyl groups on the nitrogen. The infrared dye can be present as a liquid-crystalline dispersion. This class of infrared dyes form J-aggregrated species in a liquid-crystalline or a solid particle dispersion with high IR density and low visible absorbance.
