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 a coupling agent. In the image forming medium, irradiation of the imaging layer cause the photobase generator to generate a base that reacts with the coupling agent to produce an image.
