Claims
- 1. A process for producing an image-receiving sheet for use in an image-forming system wherein said sheet is brought into contact with a heat transfer sheet, said heat transfer sheet comprising a support and a heat transfer layer provided on the support comprising a heat transferable dye contained in a synthetic resin binder, wherein an image is formed on the image-receiving sheet by contacting the heat transfer layer with the image-receiving sheet and selectively heating at least a portion of the heat transfer sheet with heating means to transfer the dye selectively from the heat transfer layer to the image-receiving sheet, the process comprising:
- preparing a substrate;
- applying a composition for forming an image-receiving layer onto the substrate, the composition comprising:
- (a) a synthetic resin for receiving the dye transferred from the heat transfer layer of the heat transfer sheet;
- (b) a dye-permeable releasing agent for preventing heat adhesion of the synthetic resin binder of the heat transfer sheet to said image-receiving layer upon heating thereof by the heating means; and
- (c) a solvent;
- pre-drying the composition thus applied in a dryer, such that the solvent is thoroughly removed from the applied composition; and
- drying the composition such that at least a portion of said releasing agent is exuded to form a releasing agent layer on at least a portion of a surface of the image-receiving layer.
- 2. A process for producing an image-receiving sheet as claimed in claim 1, wherein said heating means comprises a dot-type heating device.
- 3. A process for producing an image-receiving sheet as claimed in claim 1, wherein said heating means comprises a thermal head.
- 4. A process for producing an image-receiving sheet as claimed in claim 1, wherein said substrate is selected from the group consisting of synthetic papers, flexible thin sheets of paper and flexible thin sheets of plastic film.
- 5. A process for producing an image-receiving sheet as claimed in claim 1, wherein said releasing agent is selected from the group consisting of solid waxes, fluorine- or phosphate-containing surfactants and silicon oils.
- 6. A process for producing an image-receiving sheet as claimed in claim 1, wherein said releasing agent is selected from the group consisting of silicone oils and hardened-type silicone oils.
- 7. A process for producing an image-receiving sheet as claimed in claim 1, wherein said synthetic resin of the image-receiving layer is selected from the group consisting of resins having at least one ester linkage, resins having at least one urethane linkage, resins having at least one amide linkage, resins having at least one urea linkage and resins having at least one highly polar linkage.
- 8. A process for producing an image-receiving sheet as claimed in claim 1, wherein said synthetic resin of the image-receiving layer is selected from the group consisting of synthetic resins having a glass transition temperature of from -100.degree. to 20.degree. C. while having a polar radical, synthetic resins having a glass transition temperature of at least about 40.degree. C. and mixtures thereof.
- 9. A process for producing an image-receiving sheet as claimed in claim 1, wherein said dye is transferable to said image-receiving sheet by heating said heating means for a few milliseconds.
- 10. A process for producing an image-receiving sheet for use in an image-forming system wherein said sheet is brought into contact with a heat transfer sheet, said heat transfer sheet having a support and a heat transfer layer provided on the support comprising a heat transferable dye contained in a synthetic resin binder, wherein an image is formed on the image-receiving sheet by contacting the heat transfer layer with the image-receiving sheet and selectively heating at least a portion of the heat transfer sheet by heating means to transfer the dye selectively from the heat transfer layer to the image-receiving layer, the process comprising:
- preparing a substrate;
- applying a first composition for forming an image-receiving layer onto the substrate, the composition comprising a synthetic resin for receiving the dye transferred from the heat transfer layer of the heat transfer sheet, and a solvent;
- drying the first composition thus applied;
- applying a second composition onto the thus formed image-receiving layer to form a releasing agent layer for preventing adhesion of the heat transfer sheet to said image-receiving layer upon heating thereof by the heating means, the second composition comprising a dye-permeable releasing agent;
- pre-drying the second composition thus applied such that the solvent is thoroughly removed from the applied second composition; and
- drying the second composition.
- 11. A process for producing an image-receiving sheet as claimed in claim 10, wherein said heating means comprises a dot-type heating device.
- 12. A process for producing an image-receiving sheet as claimed in claim 10, wherein said heating means comprises a thermal head.
- 13. A process for producing an image-receiving sheet as claimed in claim 10, wherein said substrate is selected from the group consisting of synthetic papers, flexible thin sheets of paper and flexible thin sheets of plastic film.
- 14. A process for producing an image-receiving sheet as claimed in claim 10, wherein said releasing agent is selected from the group consisting of solid waxes, fluorine- or phosphate- containing surfactants and silicone oils.
- 15. A process for producing an image-receiving sheet as claimed in claim 10, wherein said releasing agent is selected from the group consisting of silicone oils and hardened-type silicone oils.
- 16. A process for producing an image-receiving sheet as claimed in claim 10, wherein said synthetic resin of the image-receiving layer is selected from the group consisting of resins having at least one ester linkage, resins having at least one urethane linkage, resins having at least one amide linkage, resins having at least one urea linkage and resins having at least one highly polar linkage.
- 17. A process for producing an image-receiving sheet as claimed in claim 10, wherein said synthetic resin of the image-receiving layer is selected from the group consisting of synthetic resins having a glass transition temperature of from -100.degree. to 20.degree. C. while having a polar radical, synthetic resins having a glass transition temperature of at least about 40.degree. C. and mixtures thereof.
- 18. A process for producing an image-receiving sheet as claimed in claim 10, wherein said releasing agent layer is provided only on a part of the image-receiving layer.
- 19. A process for producing an image-receiving sheet as claimed in claim 10, wherein said dye is transferable to said image-receiving sheet by heating by said heating means for a few milliseconds.
