PURPOSE:To enhance preservation stability, by combining a transfer sheet in which a coloring matter layer comprising a coloring matter having an epoxy group is provided on a base with a recording sheet in which a recording layer comprising an active hydrogen compound or an organic acid anhydride is provided on a base. CONSTITUTION:A coloring matter having an epoxy group, selected from azo, anthraquinone, quinophthalone or other dyes, e.g., a compound of formula I, II or III, is mixed with a resin having a high melting point or a high softening point such as a polysulfone and a polyether sulfone, a solvent such as benzene, or the like to prepare an ink, which is applied to a base such as a tissue paper and a plastic film, followed by drying to obtain the transfer sheet. On the other hand, a coating liquid comprising an active hydrogen compound having a hydroxyl group, an amino group, a carboxyl group or the like or an organic acid anhydride such as a compound of formula IV, V or VI is applied to a base such as a paper and a resin film, followed by drying to provide the recording layer, thereby obtaining the recording sheet. |
