  • INKLESS REIMAGEABLE PRINTING PAPER AND METHOD
    Publication number: 20080311519
    Abstract: An image forming medium includes a substrate, and an imaging layer coated on or impregnated into said substrate, wherein the imaging layer includes an imaging composition including a photochromic or photochromic-thermochromic material dissolved or dispersed in a solvent or polymeric binder, wherein the imaging composition is imageable by light of a first wavelength and erasable in a short time period by a combination of heat and light of a second wavelength such that simultaneous erase with heat and light of the second wavelength is faster than erase by heat alone and exhibits a reversible transition between a colorless and a colored state.
