Patent 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 photoacid generator and an acid-base indicator. In the image forming medium, irradiation of the imaging layer causes the photoacid generator to generate an acid that reacts with the acid-base indicator to produce an image.
