    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.

  • Patent number: 7091255
    Abstract: A method of multiphoton photosensitizing a photoreactive composition comprises irradiating the composition with light sufficient to cause simultaneous absorption of at least two photons, thereby inducing at least one acid- or radical-initiated chemical reaction where the composition is exposed to the light. The composition comprises: (a) at least one reactive species that is capable of undergoing such reaction; and (b) at least one multi-component, multiphoton photoinitiator system.
