image-forming medium and the medium for forming and imaging method is provided that is. The disclosed medium can be strongly colored under room illumination (or intended UV) to form an image, and can be selectively discolored at an appropriate light wavelength. In one embodiment, the image-forming medium substrate (e.g., paper sheet), the photochromic material contained in the substrate, and the light that is contained in the photochromic material can comprise an absorbent material. The image to create a temporary image-forming medium to an exemplary method of using the first image by applying a coating solution containing photochromic material to the substrate or paper can comprise the formation of a forming medium. The image-forming medium can have a medium color, then it is exposed the photochromic material selectively to light through a mask so as to convert to a colorless form in pigmented form, to form an image having a color contrast against the background You can. ;
