Abstract: There is disclosed a reversible recording material having a liquid crystal mixture comprising at least two cholesteric liquid crystal compounds. The cholesteric liquid crystal compounds which are contained in the reversible recording material has a molecular weight of less than 2000 and a grass transition temperature equal to or more than 30° C. The two cholesteric liquid crystal compounds are compatible each other. After at least a part of the reversible recording material is heated to a temperature where the part of the reversible recording material becomes a cholesteric liquid crystal phase, the part of the reversible recording material is rapidly cooled down to below the glass transition temperature thereof, so that a reflecting color from the reversible recording material can be fixed to achieve a recording.
