COMPOSITION, PROCESS OF PREPARATION AND METHOD OF APPLICATION AND EXPOSURE FOR LIGHT IMAGING PAPER

摘要

The present invention provides dual energy imaging compositions, processes for forming dual energy imaging compositions, methods for forming images using dual energy imaging compositions and substrate (e.g., paper web) treated (e.g., coated) on one or both sides with a dual energy imaging composition. Also provided is a particulate comprising a matrix of polymer material and containing one or more image- forming agents and a photo-oxidizing agent useful in making dual energy imaging compositions.
