<P>PROBLEM TO BE SOLVED: To provide a reversible multicolor display medium and a multicolor display method using the same enabling a multicolor display by a simple and rapid process. <P>SOLUTION: The reversible multicolor display medium has a structure laminating a plurality of reversible recording sheets which form a layer on a transparent support containing the reversible heat-sensitive recording composition which contains an electron acceptive compound and an electron donative color-developing compound, and can form a relatively colored state and a decolored state due to a difference in the heating temperature and/or the cooling speed after heating. The electron donative color-developing compound contained in the reversible heat-sensitive recording composition varies for each sheet (1). The reversible multicolor display medium has a layer on a transparent support containing the reversible heat-sensitive recording composition which comprises a plurality of divided display regions, contains the electron acceptive compound and the electron donative color-developing compound varied according to each display region, and can form a relatively colored state and a decolored state due to a difference in the heating temperature and/or the cooling speed after heating. The layer is folded at the boundary of the respective display regions to enable multicolor displaying (2). <P>COPYRIGHT: (C)2004,JPO |
