Abstract
Photographic film nucleating agents comprising aryl sulfonamidophenyl hydrazides containing alkene, alkadienyl, alkapolyenyl or cycloalkenyl substituted pyridinium functionality; these nucleators produce better dot quality and superior contrast characteristics in image-wise exposed film elements and wider compatibility with standard rapid access developers and obviate the need to include boosters in the film or in the developer.
