Claims
- 1. A process for producing raised images, comprising the steps of:
- superposing, on an image-receiving sheet, a heat transfer printing sheet comprising a substrate sheet and a thermally-expandable ink layer formed thereon,
- heating image-wise the thermally-expandable ink layer and bringing the heat transfer printing sheet into pressure contact with the image-receiving sheet,
- releasing the heat transfer printing sheet from the image-receiving sheet, thereby separating image-wise the thermally-expandable ink layer from the heat transfer printing sheet, and transferring it to the image-receiving sheet,
- applying light to the thermally-expandable ink layer which has been transferred image-wise to the image-receiving sheet to expand it, thereby obtaining raised images.
- 2. The process according to claim 1, wherein the light to be applied to the thermally-expandable ink layer which has been transferred image-wise to the image-receiving sheet has a maximum-energy wavelength of 0.8 to 100 micrometers.
- 3. The process according to claim 2, wherein the light has a maximum-energy wavelength of 1.0 to 4.0 micrometers.
