Abstract: Disclosed herein is a recording method for recording an image on a thermosensible image bearing medium that contains liquid crystal material. The liquid crystal exhibits a cholesteric phase at a temperature range higher than a room temperature so as to reflect selected wavelength of light based on heated temperature within the temperature range. Since the cholesteric liquid crystal material has a different response time for each selective reflection wavelength, an optimum energy application time is required for obtaining a desired recording color. Accordingly, in the recording method, it is getting higher the heating temperature, shorter the application time. The application time can be adjusted by the pulse width and/or pulse number of the applied energy.

Abstract: Disclosed is a liquid crystal display element which comprises a pair of substrates and a liquid crystal layer held between the pair of substrates and including liquid crystal that exhibits a cholesteric phase. At least one of the substrates has an orientation film that comprises a polyimide having a mesogenic group therein and has not undergone rubbing.

Abstract: The invention provides an information recording/displaying card and an information recording/displaying system using the card in which invisible information can be recorded, the invisible information can be displayed as visible information and visible information can be written/erased as color images at a practical speed. The information recording/displaying card includes a visible information display part and an invisible information recording part. These parts are disposed, for example, on the front and back surfaces of the card, respectively, or arranged side by side on the front or back surface thereof. The visible information display part includes, as a main component, a low molecular weight cholesteric liquid crystal compound having an isotropic phase transition temperature higher than a melting point, so that information can be displayed, written once and erased therein.

Abstract: A heat reversible recording medium is disclosed which includes a cholesteric liquid crystal compound. By selective application of differing temperature profiles, regions of the recording medium can be fixed in states which selectively reflect light in different wavelengths thus providing the ability to fix color images in the medium. The disclosure also includes a method of recording a color image using a medium which includes a cholesteric liquid crystal compound, an apparatus for fixing an image in the recording medium as well as several cholesteric liquid crystal compounds which are suitable for use in the method and apparatus.

Abstract: Cholesteric liquid crystal compositions and a recording medium which includes cholesteric liquid crystal composition are disclosed. The cholesteric liquid crystal composition has a characteristic, in a cholesteric phase, of reflecting visible light in accordance with temperature. By rapidly cooling the display from a cholesteric phase, the material can be solidified in a reflection state. The cholesteric material also has the characteristic during a transition from a solid phase to a cholesteric phase of having of an enthalpy &Dgr;Hch at a substantially constant value during a time when a temperature thereof increases during one of differential thermal analysis and differential scanning calorimetry.

Abstract: A rewritable thermosensible recording material shown by the following chemical formula. This recording material can be produced by condensing a derivative of dicarboxylic acid and cholesterol or by making halide dicarboxylic acid and cholesterol react to each other. By locating this material purely or as a mixture between a base layer and a transparent protective layer, a rewritable thermosensible recording medium can be obtained.
