Abstract
When a temporary adhesive layer for peelably bonding a transfer-receiving material to a thermal transfer sheet comprising a substrate film and a heat-fusible ink layer disposed on one side thereof is caused to comprise a specific adhesive, an excellent composite thermal transfer material is provided. In such a composite thermal transfer sheet, the thermal transfer sheet is firmly bonded to the transfer-receiving material so as not to cause wrinkles or deviation, both of these members may easily be peeled from each other so that the ink layer is exactly transferred to the paper in a transfer region and it is not transferred thereto at all in a non-transfer region, whereby the transfer-receiving material is not contaminated. Further, when at least one end portion of a sheet-type composite thermal transfer sheet is fixed, there is provided a composite thermal transfer sheet wherein unintended peeling is prevented.
