ABSTRACT:
The addition of water-soluble triaryl compounds selected from the group consisting of phosphines, amines, arsines, bismuthines and stibylidynes provides sensitizing effects and, when added to spectrally sensitized emulsions, provides a supersensitizing effect. The activity of these compounds is additive with other supersensitizers.
