PURPOSE:To obtain a heat transfer printing sheet capable of providing clear images plural times, by providing on a base a layer comprising a heat-sublimable colored dye and a thermoplastic substance containing 30-80% of a wax form substance having a melting point or softening point of 50-150 deg.C. CONSTITUTION:A heat-sublimable colored dye and a thermoplastic substance containing 30-80% of a wax form substance having a melting point or softening point of 50-150 deg.C are melted and mixed with each other, and the resultant mixture is applied to a base by a hot melt coating method, or the components are dispersed in an organic solvent such as a toluene and a methyl ethyl ketone, and the resultant dispersion is applied to the base by a wiper or the like, to produce a transfer sheet. In this case, the amount of the components deposited on the base is preferably 5-300g/m<2> as solids. The heat-sublimable dye is preferably a disperse dye based on monoazo or anthraquinone. A wax such as paraffin wax and a carnauba wax which has a melting point of not lower than 50 deg.C is used. |
