Intermediate transfer recording medium and process for producing the same
The present invention relates to an intermediate transfer recording medium, that can yield thermally transferred images which are excellent in various fastness properties even under severe service conditions, can transfer a protective layer on an image with good accuracy in a simple manner, and can provide an object with an image formed thereon which is highly difficult to be altered or forged, a process for producing the same, and a method for image formation. The intermediate transfer recording medium comprises: a sheet substrate provided with a resin layer; and a transparent sheet provided with a receptive layer, said transparent sheet provided with the receptive layer having been stacked on the sheet substrate provided with the resin layer, the transparent sheet portion including the receptive layer having been half cut, a hologram formation layer being stacked on the transparent sheet, the resin layer being separable from the transparent sheet.
1. An intermediate transfer recording medium comprising: a sheet substrate provided with a resin layer; and a transparent sheet provided with a receptive layer, said transparent sheet provided with the receptive layer having been stacked on the sheet substrate provided with the resin layer so that the resin layer faces the transparent sheet, the transparent sheet portion including the receptive layer having been half cut, the resin layer being separable from the transparent sheet, a hologram formation layer being provided between the transparent sheet and the receptive layer.
2. The intermediate transfer recording medium according to claim 1 , wherein the whole portion except for the image forming portion has been separated and removed using the half cut as the boundary between the image forming portion remaining unremoved and the removal portion.
3. The intermediate transfer recording medium according to claim 1 , wherein a patch portion as the image forming portion, which has been separated by the half cutting, has a size smaller than the object in its whole area on which an image is to be transferred.
4. The intermediate transfer recording medium according to claim 1 , wherein a patch portion as the image forming portion, which has been separated by the half cutting, has a partially removed portion relative to the object.
5. The intermediate transfer recording medium according to claim 1 , wherein the total width of the intermediate transfer recording medium is larger than the width of the object in its face on which an image is to be transferred.
6. A process for producing an intermediate transfer recording medium comprising: a sheet substrate provided with a resin layer; and a transparent sheet provided with a receptive layer, said transparent sheet provided with the receptive layer having been stacked on the sheet substrate provided with the resin layer so that the resin layer faces the transparent sheet, the transparent sheet portion including the receptive layer having been half cut, a hologram formation layer being provided between the transparent sheet and the receptive layer, the resin layer being separable from the transparent sheet, said process comprising the steps of:
providing an original sheet comprising a hologram formation layer formed on a transparent sheet;
forming a receptive layer on the original sheet;
applying the transparent sheet on its side opposite to the receptive layer side, in which a register mark has been previously provided at a predetermined position for each screen unit, through a resin layer; and then
reading the register marks to perform registration for half cutting and then to perform half cutting.
7. The process for producing an intermediate transfer recording medium according to claim 6 , wherein, after the half cutting, the whole portion except for the image forming portion is separated and removed using the half cut as the boundary between the removal portion and the image forming portion remaining unremoved.
8. A method for image formation, comprising the steps of: providing the intermediate transfer recording medium according to any one of claims 1 to 5 ; forming a transfer image on the receptive layer; and then re-transferring only the portion with the image formed thereon onto an object to form an image on the object.
