Claims
- 1. A thermal transfer image-receiving sheet comprising paper as a substrate sheet and, provided on said substrate sheet in the following order, an expanded layer and a receptive layer, an undercoat layer being provided between said substrate sheet and said expanded layer, said expanded layer containing a microcapsule.
- 2. The thermal transfer image-receiving sheet according to claim 1, wherein said undercoat layer has been formed by coating a coating solution comprising a resin and an organic solvent.
- 3. The thermal transfer image-receiving sheet according to claim 2, wherein said undercoat layer further comprises a pigment.
- 4. The thermal transfer image-receiving sheet according to claim 1, wherein said expanded layer has been formed by coating an aqueous coating solution.
- 5. The thermal transfer image-receiving sheet according to claim 4, wherein the cell diameter of said expanded layer is in the range of from 20 to 50 μm.
- 6. The thermal transfer image-receiving sheet according to claim 1, wherein said expanded layer contains a microcapsule comprising a low-boiling organic solvent surrounded by the wall of a thermoplastic resin.
- 7. The thermal transfer image-receiving sheet according to claim 1, wherein said expanded layer has a thickness in the range of from 30 to 100 μm.
- 8. The thermal transfer image-receiving sheet according to claim 1, which further comprises a curl preventive layer on the other surface of said substrate sheet.
- 9. A thermal transfer image-receiving sheet comprising a substrate sheet of paper composed mainly of pulp and, provided on said substrate sheet in the following order, an expanded layer, an intermediate layer and a receptive layer, said intermediate layer having been formed by coating an aqueous coating solution.
- 10. The thermal transfer image-receiving sheet according to claim 9, wherein said aqueous coating solution is an aqueous solution of a water-soluble resin, a dispersion of a resin or an emulsion of a resin.
- 11. The thermal transfer image-receiving sheet according to claim 9, wherein said resin constituting said intermediate layer has a glass transition temperature in the range of from −30 to 20° C.
- 12. The thermal transfer image-receiving sheet according to claim 9, wherein said resin constituting said intermediate layer is a crosslinking resin.
- 13. The thermal transfer image-receiving sheet according to claim 9, wherein an undercoat layer is provided between said substrate sheet and said expanded layer.
