Acyl-hydrazides nucleating agents promotes high contrast and high photographic speed in the black and white negative films. Such nucleating agents have been used in graphic arts films since 1984. Now, we are interested in these acyl-hycdrazides as a new class of imagewise releaser of a photographically useful group or a new redox compound.<BR>This article describes some kinetic studies concerning with the oxidation reaction followed by hydrolysis of acyl-hydrazide derivatives and also some properties of the key reaction intermediate. New application of acyl-hydrazide compounds to the developer inhibitor releaser (DIR) in the micro-area inhibition technology (MAI-Technology) of Fuji Super Grandex graphic arts materials, is also reviewed.
