    摘要: A decolorizable image forming material comprising a color former, a developer and a decolorizer, the decolorizer comprising a highly amorphous phase separation inhibitor and a slightly amorphous phase separation inhibitor. A cyclic sugar alcohol is used as the highly amorphous phase separation inhibitor, and a non-aromatic cyclic compound having five-membered or larger ring substituted by a hydroxyl group or a derivative of a cyclic sugar alcohol is used as the slightly amorphous phase separation inhibitor. The decolorizable image forming material can be decolored easily after image formation by a solvent and the decolored state of which can be maintained stably, thereby making it possible to reuse paper sheets.

    摘要: An erasable image forming material includes a color former, a developer, a binder resin, and a polymer decolorizer having an electron donating group capable of physically or chemically adsorbing the developer. This polymer decolorizer is, e.g., a polymer compound having a sugar skeleton, representatively starch. This image forming material can form sharp images and erase images by heat or a solvent to achieve a good erased state.

    摘要: Impurities mixed in the liquid crystal device are detected by a method comprising the steps of applying a DC electric field to a liquid crystal device having a liquid crystal layer between a pair of electrodes, and irradiating the liquid crystal device with light within a specific wavelength, while an AC pulsed electric field is being applied to the liquid A crystal device after the DC electric field is removed to obtain a field response curve corresponding to time-dependent change of light intensity during a cycle of the AC pulsed electric field by time-resolved measurement of light passed through the liquid crystal layer, wherein the impurities are detected on the basis of specific quantitative change in the electric field response curve as a function of elapsed time after the DC electric field is removed.
