Zusammenfassung:	PURPOSE: To enable multicolor indication in which visibility is excellent by together providing both such a recording means as the scattering degree of light reversibly changes by impartment of heat and such as recording means as color reversibly changes by impartment of light. CONSTITUTION: The blend of a complex of an organic low molecular compound polymer compound, a polymer liquid crystal and a polymer blend is used as a material which constitutes as information recording medium and is utilized for such a recording means as the scattering degree of light reversibly changes by impartment of heat. Such a recording means as color reversibly changes by impartment of light is obtained by providing a layer containing a photochromic material, a photothermochromic material and a layer containing them. The information recording medium is constituted by providing a thermal reversible recording layer 2 and a photo reversible recording layer 1 on the base material 3 as the separate layers.
