    • 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.

    • 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.
    • 在包含绕线筒的转印印刷胶卷和卷绕在绕线管上的转印印刷膜的情况下,转印印刷膜的内侧后端在膜的宽度上牢固地粘合在线轴上,以防止膜分离 即使当胶片已经完全从筒管中取出时,由于用于支付胶片的进给电动机的力的线轴。 由于在膜的宽度上形成了很强的粘合,所以可以以均匀的张力分布将薄膜缠绕在线轴上,并且不会使彼此缠绕的薄膜的侧边缘偏移。 当胶片已经完全支付到尾端时,胶片上的张力增加,使得进给电动机上的负载也增加。 可以利用增加的负载来检测胶片的末端。 这消除了对膜的后端施加的“END”标记的需要,用于检测胶片的末端。
