PURPOSE:To cause no rapid decrease in transfer concentration even through an increase in the number of times of printing and also to cause no deterioration of sensitivity even in the early stage of the number of times of recording by forming a dye-supplying layer through dispersing a sublimable dye and a microcapsule containing said dye in an organic binding agent. CONSTITUTION:When a dye is particulately contained in a microcapsule and further that outside the microcapsule in a dye-supplying layer 2 is caused to exist in a molecule-dispersed state, the dye in and outside the microcapsule plays a role satisfactorily. The percentage content of the dye in and outside the microcapsule is dye quantity outside microcapsule/dye quantity in microcapsule=1/9-8/2 (weight ratio) and preferably 2/8-4/6. Moreover, when there is a difference in glass-transition temperature or softening temperature between dye transfer contribution layer 3 and dye-supplying layer 2, a resin or natural or synthetic rubber of 0 deg.C and less glass-transition temperature or 60 deg.C and less softening temperature is preferred as resin having a low glass-transition temperature or low softening temperature. |
