ABSTRACT:
An unballasted arylhydrazide is disclosed the aryl moiety of which is substituted with a group of the formula ##STR1## where one of X and X' represents --NH--, the other represents a divalent chalcogen, and R represents an aliphatic or aromatic residue. The arylhydrazides, when applied to halftone imaging in conjunction with silver halide emulsions, photographic elements, and imaging processes, produce images of improved dot quality and low levels of pepper fog.
