Abstract: PROBLEM TO BE SOLVED: To provide a method of recording a multicolor image and a multicolor image recording device by which a uniform multicolor image can be efficiently recorded in a thermosensitive recording medium having a simple structure in which a thermosensitive recording layer containing medium mol.wt. cholesteric liquid crystal recording material and by which an increase in the width of a picture line depending on the color is prevented. SOLUTION: The thermosensitive recording medium has a thermosensitive recording layer containing a thermotropic liquid crystal compound which forms a cholesteric liquid crystal phase formed between two substrates at least one of which is transparent. In the method of recording a multicolor image, the thermosensitive recording layer is heated to a temperature where the layer shows isotropic or cholesteric liquid crystal phase, and then the layer is cooled at a specified cooling rate to form a cholesteric glass phase having the solidified arrangement of helical molecules of the cholesteric liquid crystal phase. Thus, an image showing a selective reflection color produced by the arrangement of helical molecules is recorded in the medium.

Abstract: PROBLEM TO BE SOLVED: To fix target reflected light simple and easily only by controlling a cooling velocity from an isotropic phase. SOLUTION: A recording layer composed of a thermal recording material comprising a cholesteric liquid crystal compound or a mixture containing the compound which is held between two substrates at least one of which is transparent is provided. After the recording layer allowed its part or the whole area to be heated to a temperature which indicates an isotropic phase or a cholesteric liquid crystal phase at high temperatures, the recording material, with a proper cooling velocity selected corresponding to a selected wavelength for desired fixing, is cooled to the glass transition temperature of cholesteric liquid crystal compound or below or to room temperature so that recording can be done with a desired cholesteric reflected color fixed in the cooled area.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display recording device which obviates the occurrence of rainbow-like blot and a liquid crystal display recording method in the color liquid crystal display recording device driven by heat and electric field and the liquid crystal display recording method. SOLUTION: A liquid crystal recording sheet is formed of a film consisting of polymer dispersion type liquid crystals formed by dispersing cholesteric liquid crystal particles capable of fixing arbitrary reflection colors at room temp. into a polymer matrix or polymer network type liquid crystals formed by dispersing the cholesteric liquid crystals into a three-dimensional network structure formed by the polymer. The alignment state of the liquid crystals dispersed by cooling the sheet described above in the state of impressing the high electric field thereto after heating is made uniform and a mode to reflect the light of an arbitrary wavelength is attained. The alignment state of the liquid crystals is made random and a mode to allow the uniform transmission of the light of a visible region or to reflect this light is attained by cooling the sheet under impression of the low electric field or without the electric field after heating. Displaying and recording are executed by forming the display recording medium which is reversibly changed in both modes described above in such a manner that the area to be impressed with the electric field is made narrower than the heating surface area.
