  • Patent number: 5013711
    Abstract: The image-receiving sheet of the present invention is used in combination with a heat transfer sheet having a colorant layer containing a sublimable dye on one surface of a substrate sheet. The image-receiving sheet includes a receiving layer containing a synthetic resin and an antioxidant including a specific structure as described above for receiving the sublimable dye migrated from the colorant layer of the heat transfer sheet formed on one surface of a substrate sheet, and therefore it can give a hard copy having extremely high light resistance of the recorded image of which color will be faded only with difficulty even when stored for a long term.
