THERMAL TRANSFER SHEET, THERMAL TRANSFER IMAGE RECEIVING SHEET AND THERMAL TRANSFER RECORDING METHOD

PURPOSE:To enhance the utilization efficiency of heat energy and to form a sharp high density image at a high speed even by low heat energy. CONSTITUTION:In a thermal transfer sheet wherein a dye layer is provided on the surface of a base material film, an ultrafine granular material with heat diffusivity of 0.005cm /s or more and a particle size of 0.5mum or less is added to the base material film and/or the dye layer and a thermal transfer image receiving sheet is obtained by providing a dye receiving layer on at least one surface of a base material sheet and characterized by that an ultrafine granular material with heat diffusivity of 0.005cm /s or more and a particle size of 0.5mum or less is added to the dye receiving layer. A thermal transfer recording method is performed using the thermal transfer sheet and the thermal transfer image receiving sheet.
