Claims
- 1. A thermal transfer recording process, comprising the steps of:
- a) superimposing an image recording medium composed of a sublimating dye on an image receiving sheet; and
- b) applying heat imagewise to the image recording medium to transfer an image from the image recording medium to the image receiving sheet,
- wherein the running speed of the image receiving sheet is n-times (n>1) as large as that of the image recording medium, and wherein the image receiving sheet comprises a substrate and a dye receiving layer containing an unmodified silicone oil, a modified silicone oil, and a resin.
- 2. The process of claim 1, wherein the running speed of the image receiving sheet is n-times (n>10) as large as that of the image recording medium.
- 3. The process of claim 1, wherein the unmodified silicone oil is selected from the group consisting of dimethyl silicone oil, methyl phenyl silicone oil and methyl hydrogen silicone oil.
- 4. The process of claim 1, wherein the modified silicone oil is modified with a modifier selected from the group consisting of alcohol, polyether, carboxyl and epoxy compounds.
- 5. The process of claim 1, wherein the weight ratio of the unmodified silicone oil to the modified silicone oil is in the range of 0.05:0.95 to 0.95:0.05.
- 6. The process of claim 1, wherein the weight ratio of the unmodified silicone oil to the modified silicone oil is in the range of 0.20:0.80.
- 7. The process of claim 1, wherein the total amount of the unmodified and modified silicone oils is in the range of 2 to 15% by weight based on the amount of resin in the dye receiving layer.
- 8. The process of claim 1, wherein the resin is selected from the group consisting of polyester, poly(vinyl chloride), acrylic polymer, polyurethane, poly(vinyl acetate) and polyamide.
- 9. The process of claim 1, wherein the resin is a homopolymer of vinyl chloride or a copolymer of vinyl chloride.
- 10. The process of claim 1, wherein the resin is crosslinked with an isocyanate compound or melamine resin through a group having an active hydrogen therein.
- 11. The process of claim 10, wherein the cross-linked resin has a glass transition temperature of 80.degree. C. or lower.
- 12. The process of claim 1, wherein the dye receiving layer has a gel fraction of 70% by weight of more.
- 13. The process of claim 1, wherein the gel fraction of the dye receiving layer is 90% by weight or more.
- 14. The process of claim 1, wherein the dye receiving layer has a thickness of 1 to 20 .mu.m.
- 15. The process of claim 10, wherein an intermediate layer is interposed between the dye receiving layer and the substrate.
