Ultra-high Contrast Imaging Technology by Acyl-hydrazides in Photosensitive Materials for Graphic Arts

Abstract

Ultra-high contrast imaging system by hydrazide-nucleated infectious development has been used as a high quality film making system instead of a lith-development system for graphic arts. The hydrazide system is based on the reaction of the hydrazine compound with the o xidation product of the developer, and an imagewise production of strong fogging species. Such hydrazides are called as a nucleator.
In this paper, the progress of the nucleation technology developed within FUJI FILM is reported, and some points such as the relationship between the hydrazide structure and the nucleation activity, the nucleation accelerators, the micro-area inhibition technology, and the low pH nucleation technology are discussed.
