    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 system is disclosed for measuring the crystallization of crystalline-amorphous mixtures. The system includes a sample holder. and a heating apparatus to melt a ink composition and to keep the melted ink composition at a first specified temperature for a first period of time. The system includes a cooling apparatus to receive the melted ink composition, to cool the melted ink composition and to maintain the cooled ink composition at a second specified temperature. The system includes a microscope and a video recording device to capture images of the cooled ink composition for a second period of time A video processing computer includes a memory, a processor and software instructions and the software instructions causes the computer to extract crystallization parameters about the cooled ink composition from the captured images. The crystallization parameters identify fast solidifying crystalline inks that have a short time duration from onset of crystallization until crystallization.
