DETAILED DESCRIPTION An object of the present invention is to provide a thermal transfer dye image-receiving sheet applicable to various types of dye-thermal transfer printers, including a sublimating dye thermal transfer printing system, and capable of forming and fixing clear dye images or pictures thereon without undesirable curling and wrinkle-forming due to a local heating of the sheet.
Another object of the present invention is to provide a thermal transfer dye image-receiving sheet able to effectively record continuous tone full colored clear images or pictures thereon at a high resolution and reproductivity.
Still another object of the present invention is to provide a dye image-receiving sheet which can be smoothly fed to, moved through, and delivered from a printer, without an undesirable blocking and damaging thereof.
The above-mentioned objects can be attained by the thermal transfer dye image-receiving sheet of the present invention which comprises (A) a substrate sheet composed of: (a) a core sheet comprising a thermoplastic resin, (b) a front coated film layer formed on a front surface of the core sheet, and comprising a thermoplastic-resin, and (c) a back coated film layer formed on a back surface of the core sheet, and comprising a thermoplastic resin; and (B) a dye image-receiving layer formed on the front coated film layer of the substrate sheet and comprising a synthetic resin capable of being dyed with dyes, the core sheet and the front and back coated film layers satisfying the following relationships (1) and (2): T.
