るものと推測される。The reason why the image quality is improved by providing a transparent intermediate layer as described above is not necessarily clear, but the printing area is deformed by the heat from the thermal head during printing, and the head is brought into close contact or fits in an optimal state. It is presumed that image density is developed and image quality is improved by combining with transparency.

乾燥させて透明受容層を形成した。Polyethylene terephthalate (manufactured by Panac Industries: T-PET) of 100 μm JW was used as a transparent base material, and a receptor layer forming composition having the following composition was coated on the surface thereof by wire bar coating so that the dry thickness was 4 μm. After temporary drying with a dryer, a transparent receiving layer was formed by drying in an oven at 100° C. for 30 minutes.

、鮮明な投影画像が得られた。The above thermal transfer sheet is overlapped with the thermal transfer sheet, and a thermal head is used from the base material side of the thermal transfer sheet (output 1-
/ dot, pulse width 0.3 to 0.45 m/sec, dot density 3 dots/dot) and transfer the disperse dye in the thermal transfer layer of the thermal transfer sheet to the receiving layer of the thermal transfer sheet to form an image. Thereafter, when the heat transfer sheet from which the high-quality paper was peeled off was projected using an overhead projector, a clear projected image was obtained.

。As explained above, the thermal transfer sheet for producing transparent originals of the present invention has a support sheet removably provided on the surface of the transparent base material opposite to the side on which the transparent receiving layer is provided via the adhesive layer. Therefore, compared to a thermal transfer sheet that simply consists of a transparent base material and a transparent receptor layer, the transfer sheet itself maintains an appropriate stiffness and runs well in a thermal recording device. At this time, the printing energy (heat) of the thermal head is insulated by the support sheet, and the heat is accumulated on the receiving layer side.As a result, the dye transfer from the thermal transfer sheet (improves the dyeability of the dye), resulting in an increase in image density. In addition, there is an effect that sensitivity is improved and clear images can be obtained.

るという利点がある。Furthermore, according to the present invention, by providing a support sheet, the thickness of the transparent base material itself can be made thinner than conventional ones, thereby reducing the rigidity of the base material and improving image density and sensitivity. can be achieved. Furthermore, when a detection mark for a thermal recording device is provided on a support sheet, the support sheet can be peeled off before projection, which has the advantage that there is no risk of the detection mark remaining and interfering with projection. be.
