Description

ABSTRACT:
A reimageable recording medium includes a substrate, a display layer, and a protective layer. The protective layer comprises a microencapsulated diarylethene material that is capable of switching between a UV absorbing and UV transparent state. During an imaging process, the protective layer is switched from a UV absorbing state to a UV transparent state to allow UV light of a sufficient wavelength to convert a photochromic material of the display layer to a colored state to form an image. The protective material is then switched back to a UV absorbing state to prevent the UV light component from a reading source to convert unimaged areas of the display layer to change color, which would reduce the contrast and resolution of the imaged medium.
