摘要： 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.

摘要： A cholesteric display including a cholesteric liquid crystal, and a dipolar dopant having limited miscibility in the cholesteric liquid crystal is provided. In accordance with another aspect, a process is provided for forming a cholesteric liquid crystal composition by dissolving a dipolar dopant having limited solubility into a cholesteric liquid crystal. The liquid crystal composition can be utilized to produce a cholesteric display. The liquid crystal domains in the liquid crystal composition rotate away from a planar state in the presence of an applied electric field and the degree of rotation is a function of the applied electric field strength. The reflected color is then a function of the applied electric field.
