Further, in the present invention, a release agent such as amino-modified silicone, epoxy-modified silicone, alkyd-modified silicone, etc. can be contained in the dye-receiving layer. Use of these silicones further improves the effect of preventing thermal melting with the transfer medium. However, as the silicone content increases, the storage stability after recording deteriorates as described above, so the silicone content is desirably 10% by weight or less based on the amount of resin in the dye-receiving layer.
