ABSTRACT:
An image forming medium includes a substrate and an imaging layer coated on or impregnated into the substrate, where the imaging layer includes a photobase generator and coupling agent. In the image forming medium, irradiation of the imaging layer causes the photobase generator to generate base that reacts with the coupling agent to produce an image.
