Photothermographic materials containing radiation sensitive quinone compounds and nitrobenzylidene dyes

摘要

Certain radiation sensitive quinone compounds and nitrobenzylidene dyes in photothermographic elements, compositions and processes on exposure to activating radiation, release a species which catalyzes the reduction of silver salt oxidizing agents in the presence of non-light sensitive reducing agents upon heating. The elements, after imagewise exposure, are heated to develop the image.
