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.
