Abstract: In a transfer printing film roll comprising a bobbin, and a transfer printing film wound around the bobbin, the inner trailing end of the transfer printing film is bonded to the bobbin over the width of the film so strongly as to prevent separation of the film from the bobbin due to the force of a feed motor for paying out the film even when the film has been paid out completely from the bobbin. Because of the strong bonding made over the width of the film, the film can be wound around the bobbin with a uniform distribution of tension and without offset of the side edges of the film wound over each other. When the film has been paid out completely to the trailing end, tension on the film increases so that the load on the feed motor also increases. The increased load can be utilized to detect the end of the film. This eliminates the need of an "END" mark applied to the trailing end of the film for detecting the end of the film.

Abstract: An image-receiving sheet, including a sheet substrate, an image-receiving layer which is formed on said substrate and which receives the dye migrated by heating from a heat transfer sheet and a release layer formed on said image-receiving layer, characterized in that said release layer is formed with a releasable resin having a molecular weight of 3500 to 20000.

Abstract: The image receiving sheet according to the present invention is an image receiving sheet which receives dye migrated by heat from a heat transfer sheet, wherein the image receiving sheet includes a substrate (3), a dye receiving layer (3) provided on one surface of the substrate and a curl prevention layer. The curl prevention layer includes a non-heat stretchable and shrinkable resin having a heating stretching or shrinking ratio within the range from -1.0 to 1.5% in JIS-K-6734 provided on the surface of the substrate on the side opposite to the above dye receiving layer, or between the substrate and the dye receiving layer. In the present invention, by having such a curl prevention layer as mentioned above, generation of curl by heat during image formation can be prevented to provide an image receiving sheet excellent in both conveyability of sheet and printing quality.
