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.

Composition, process of preparation and method of application and exposure for light imaging paper

The present invention provides dual wavelength imaging compositions, processes for forming dual wavelength imaging compositions, methods for forming images using dual wavelength imaging compositions and substrate (e.g., paper web) treated (e.g., coated) on one or both sides with dual wavelength imaging compositions. Also provided is a dual wavelength imaging particulate comprising a matrix of polymer material and containing: one or more image-forming agents; a photo-oxidizing agent which is activated at a first wavelength of light to cause the one or more image-forming agents to form one or more images; and a reducing agent which is activated at a second wavelength of light to cause termination of the formation of the one or more images.
