Abstract
Abstract A heat transfer sheet having a heat transfer layer on one surface of a base sheet, said heat transfer layer being formed of a material containing a dye substantially dissolved in a binder with a weight ratio of the dye to the binder (dye/binder ratio) of 0.3 or more, and said base sheet having a heat-resistant slipping layer provided on the surface on which the heat transfer layer is not provided. A heat transferable sheet to be used in combination with the heat transfer sheet, comprising a receptive sheet having (a) a base sheet and (b) a receptive layer for receiving the dye migrated from the above-mentioned heat transfer sheet on heating, said receptive sheet having an intermediate layer provided between the base sheet and the receptive layer.
