ABSTRACT:
This invention relates to a heat transfer sheet including a substrate film and a dye layer formed on the surface of the substrate film, the dye layer containing a dye and a binder resin and, if required, a release agent. The binder resin and/or release agent include a graft copolymer containing at least releasable segment selected from polysiloxane, carbon fluoride and long-chain alkyl segments grafted onto its major chain. According to this invention, there is provided a heat transfer sheet which enables an image of high density to be made at high speeds with neither adhesion between the dye layer and the dye-receiving layer nor peeling-off of the dye layer at the time of heat transfer and can produce an image on the surface of which a transparent film can be laminated.
