A dye image-receiving sheet for thermal transfer printing systems, comprising a substrtate sheet composed of a support paper sheet, a front coated layer comprising a thermoplastic resin, and optionally, a back coated layer comprising a thermoplastic resin; and a dye image-receiving layer comprising a resinous material capable of being dyed with a sublimating dye, and characterized in that the front coating layer has a Bekk smoothness of 100 seconds or more and the substrate sheet has a rigidity of 700 mgf or less. |
|
DETAILED DESCRIPTION An object of the present invention is to provide a thermal transfer image-receiving sheet capable of recording thereon sublimating dye images or pictures with an excellent clarity, a high resolution, and a high reproducibility.
Another object of the present invention is to provide a thermal transfer image-receiving sheet useful for recording sublimating dye images with a uniform quality in a continuous tone color density, without the formation of undesirable curls and wrinkles during a thermal transfer printing operation.
The above-mentioned objects can be obtained by the thermal transfer dye image-receiving sheet of the present invention, which comprises a substrate sheet composed of a support sheet comprising, as a principal component, a cellulose pulp, and a front coated layer formed on the front surface of the support sheet and comprising, as a principal component, a thermoplastic resin; and a dye image-receiving layer formed on a front surface of the front coating layer and comprising, as a principal component, a resinous material capable of being dyed with dyes for forming colored images, said front surface of the front coated layer having a Bekk smoothness of 100 seconds or more, and said substrate sheet having a rigidity of 700 mgf or less determined in the direction along which the dye image-receiving sheet is moved during a thermal transfer operation and in accordance with a test method defined in TAPPI, T543, pm 84.
