Patent abstract

A thermochromic reimageable recording medium comprises a substrate and thermochromic composition comprising a photochromic material, a transition metal salt and a binder. The thermochromic composition changes color from a colorless state to a colored state upon application of heat. The thermochromic recording medium may be used to display a viewable image by applying heat to selected areas of the medium to form a desired image. The colored state is changeable or erasable back to the colorless state by exposure to visible light.
