Claims
- 1. A thermal transfer recording sheet for forming an image on an image-receiving sheet comprising a substrate and a dye-receiving layer formed thereon, said thermal transfer recording sheet comprising:
- a substrate film, and
- a dye layer formed on the substrate film and comprising a dye, a binder and an oil-repelling agent, wherein said oil-repelling agent imparts a contact angle to tetradecane of 10.degree. or greater to an image-recorded surface of the image-receiving sheet when or after the image is formed.
- 2. A thermal transfer recording sheet for forming an image on an image-receiving sheet comprising a substrate and a dye-receiving layer formed thereon, said thermal transfer recording sheet comprising:
- a substrate film,
- a dye layer formed on the substrate film and comprising a dye and a binder, and
- an oil-repelling agent layer formed on the dye layer, wherein said oil-repelling agent layer imparts a contact angle to tetradecane of 10.degree. or greater to an image-recorded surface of the image-receiving sheet when or after the image is formed.
- 3. A thermal transfer recording sheet for forming an image on an image-receiving sheet comprising a substrate and a dye-receiving layer formed thereon, said thermal transfer recording sheet comprising:
- a substrate film,
- a dye layer formed on the substrate film and comprising a dye and a binder, and
- an oil-repelling agent layer formed on the substrate film, adjacent to the dye layer, wherein said oil-repelling agent layer imparts a contact angle to tetradecane of 10.degree. or greater to an image-recorded surface of the image-receiving sheet when or after the image is formed.
- 4. A thermal transfer recording sheet for forming an image on an image-receiving sheet comprising a substrate and a dye-receiving layer formed thereon, said thermal transfer recording sheet comprising:
- a substrate film, and
- an oil-repelling-agent-transferring layer formed on the substrate film, wherein said oil-repelling agent layer imparts a contact angle to tetradecane of 10.degree. or greater to an image-recorded surface of the image-receiving sheet when or after the image is formed.
- 5. The thermal transfer recording sheet according to claim 4, wherein the oil-repelling-agent-transferring layer comprises an agent selected from the group consisting of fluorine-modified resins, fluorine-containing surface active agents and fluorine-modified silicone oils.
- 6. The thermal transfer recording sheet according to claim 4, wherein the oil-repelling-agent-transferring layer contains fluororesins.
- 7. The thermal transfer recording sheet according to claim 4, wherein a dye layer of at least one color of yellow, magenta and cyan is formed on the same substrate surface side on which the oil-repelling-agent-transferring layer is formed.
- 8. The thermal transfer recording sheet according to claim 7, wherein the oil-repelling-agent-transferring layer further comprises a binder resin.
- 9. The thermal transfer recording sheet according to claim 8, wherein the binder resin is selected from a cellose resin, a vinyl resin and a polyester resin.
- 10. The thermal transfer recording sheet according to claim 8, wherein the oil-repelling-agent is contained in the range of from 1-30% by weight per 100 parts by weight of the binder.
- 11. The thermal transfer recording sheet according to claim 4, wherein the oil-repelling-agent-transferring layer further comprises a binder resin.
- 12. The thermal transfer recording sheet according to claim 11, wherein the binder resin is selected from a cellose resin, a vinyl resin and a polyester resin.
- 13. The thermal transfer recording sheet according to claim 11, wherein the oil-repelling-agent is contained in the range of from 1-30% by weight per 100 parts by weight of the binder.
- 14. The thermal transfer recording sheet according to claim 4, wherein the oil-repelling-agent-transferring layer has a thickness of from 0.5-5 g/m.sup.2 on the basis of coating amount.
- 15. A method for thermal transfer recording, comprising the steps of:
- superposing a sublimation thermal transfer recording sheet on an image-receiving sheet comprising a dye-receiving layer, and
- applying thermal energy to the back surface of the thermal transfer recording sheet by a heat application means to produce an image on the dye-receiving layer,
- wherein an oil-repelling agent is supplied to the image-recorded surface of the image-receiving sheet when or after the image is produced, thereby imparting a contact angle to tetradecane of 10.degree. or greater to the image-recorded surface.
- 16. The method according to claim 15, wherein the oil-repelling agent is at least one substance selected from the group consisting of fluorine-modified resins, fluorine-containing surface active agents, fluororesins and fluorine-modified silicone oils.
- 17. The method according to claim 15, wherein the heat application means is a thermal head or a laser.
- 18. A thermal transfer recording sheet for forming an image on an image-receiving sheet comprising a substrate and a dye-receiving layer formed thereon, said thermal transfer recording sheet comprising:
- a substrate film; and
- an oil-repelling agent formed on the substrate film, wherein said oil-repelling agent imparts a contact angle to tetradecane of 10.degree. or greater to an image-recorded surface of the image-receiving sheet when or after the image is formed.
