Abstract
Nucleating agents that promote high contrast in photographic films are disclosed. The nucleating agents are aryl sulfonamido hydrazides having pyridinium, phosphonium or cycloalkenylpyridinium functional groups. The nucleating agents increase the speed and contrast of graphic arts films and improve dot quality in halftone applications. Boosters are not required to obtain good dot quality and photographic speed.
