ABSTRACT:
Many photographic materials must be handled under special lighting conditions in order to prevent exposure of the material. The use of large concentrations of bleachable light absorbing layers over the photosensitive emulsion tends to leave an undesirable residual stain. The inclusion of a specific class of low intensity reciprocity failure inducers to silver halide emulsions enables the emulsions and their photographic articles to be safely handled under white light conditions.
