Problems solved by technology

For the above reasons, when a curing agent is used to form the dye-receiving layer described in International Publication No. WO2006 / 057192, the manufacturing process is complicated and large specialized manufacturing equipment is required
Therefore, productivity is low, which leads to increased production costs

[0027] [1.1 Overall structure]

[0028] First, refer to figure 1 The general structure of the thermal transfer-receiving sheet according to the preferred embodiment of the present invention is described. figure 1 It is a schematic sectional view which shows the structure of the thermal transfer receiving sheet which concerns on a preferable embodiment of this invention.

[0029] Such as figure 1 As shown, the thermal transfer-receiving sheet 100 according to the present embodiment includes a base sheet 110 and a dye-receiving layer 120 formed on the base sheet 110 .

[0030] In general, the dye-receiving layer is formed using a polymer resin as a main component. In order to improve heat resistance, a curing agent such as polyisocyanate may b...

Embodiment 1

[0079] Based on the ratios listed in Table 1 below, AS-61 (a copolymer of styrene monomer and acrylonitrile monomer in a mixing ratio of 24:76) commercially available from NipponSteel Chemical Co., Ltd. was used as the AS resin, and PEMA / HEMA copolymer as acrylic resin. Then, mix AS resin and acrylic resin. Subsequently, the mixture was diluted with a mixed solvent of 2-butanone and toluene (mixing ratio 1:1) until the solid content of the mixture was 20% by mass, and then the mixed solution for forming the dye-receiving layer thus obtained was mixed with After the mixed solution was dried, it was coated on a 150 μm synthetic paper ("YUPOFPG-150" commercially available from OjiYuka) in an amount so as to have a thickness of 3 μm, and dried at 120° C. for 1 minute to remove the solvent, thereby preparing the paper of Example 1. Thermal transfer receiving sheet.

Embodiment 2 to 6 and comparative example 1 to 5

[0081] The thermal transfer-receiving sheets of Examples 2 to 12 and Comparative Examples 1 to 5 were produced in the same manner as described in Example 1, except for the content of AS resin, content of acrylic resin, content of PEMA and HEMA. The mixing ratio, the kind of the monomer of the acrylic resin and the content of the polyester polyol were varied as listed in Table 1.

[0082] [Printing method using thermal transfer receiving sheet]

[0083] Using a thermal transfer printer (UP-DR200 printer commercially available from Sony Corporation) and an ink ribbon containing yellow (Y), magenta (M) and cyan (C) dyes and having a laminated film (L) formed therein ( UPC-204 (commercially available from Sony Corporation) was printed on the thermal transfer-receiving sheets of Examples 1 to 12 and Comparative Examples 1 to 6 manufactured as described above.

Abstract

The present invention provides a thermal transfer receiving sheet comprising: a base sheet; and a dye receiving layer formed on the base sheet, the dye receiving layer comprising styrene A mixture of copolymer A of monomer and acrylonitrile monomer and copolymer B of 2-phenoxyethyl methacrylate monomer and 2-hydroxyethyl methacrylate monomer.

Description

technical field [0001] The present invention relates to a thermal transfer-receiving sheet on which a dye is thermally transferred. Background technique [0002] A thermal transfer method using a sublimation dye involves transferring a plurality of color dots onto a thermal transfer receiving material by heating in a very short time, and reproducing a full-color image with various color dots. In such thermal transfer method, images and characters (charter) are formed by closely attaching the dye layer of thermal transfer sheet (thermally transferring sheet) The heating device heats the thermal transfer sheet from the reverse side of the dye layer, and transfers the dye contained in the dye layer onto the thermal transfer-receiving sheet. In this case, as the thermal transfer-receiving sheet, a sheet having a dye-receiving layer that receives dye from the thermal transfer sheet on the surface of the sheet-shaped base sheet is used. This thermal transfer method using sublima...
