[0108]

[0109] Use a wire-wound coater to apply the obtained ink (Y) and ink (C) to a polyethylene terephthalate film (6μm thick), and dry (about 1μm dry film thickness) to form a color料层。 The material layer. 10 parts by weight of acrylic resin (trade name: BR-80, produced by Mitsubishi Rayon Co., Ltd.) and 1 part by weight of amino-modified silicone oil (trade name: KF393, produced by Shin-Etsu Chemical Co., Ltd.) And 89 parts by weight of toluene ...

Embodiment 2～3

[0116] The preparation of ink, preparation of thermal transfer sheet, transfer recording, and light resistance test were performed in the same manner as in Example 1, except that the dye shown in Table 3 was used as the yellow dye. The results are shown in Table 4.

Embodiment 4

[0141] The ink prepared by the following method was used instead of the ink used in Example 1, and the preparation, transfer recording, and evaluation of the transfer sheet were performed in the same manner as in Example 1, thereby obtaining a recording with uniform color density. It was also confirmed that the recorded matter thus obtained had good light resistance.

Abstract

A thermal transfer sheet and yellow ink for use in thermal transfer, with which highly dense clear yellow color can be exhibited with low energy, with which a thermal transfer record excelling in color tone and light fastness can be obtained, and with which a highly dense preferable green tone can be exhibited when mixed with cyan, and to provide a thermal transfer sheet. There is provided a dye composition characterized by containing a dye having an arylidene pyrazolone skeleton and a dye having a bispyrazolone methine skeleton. There is further provided a thermal transfer ink characterized by containing a dye having an arylidene pyrazolone skeleton, a dye having a bispyrazolone methine skeleton and a medium. There is still further provided a thermal transfer sheet comprising a base material and, superimposed thereon, a color material layer containing a dye having an arylidene pyrazolone skeleton and a dye having a bispyrazolone methine skeleton.

Description

Technical field [0001] The present invention relates to a thermal transfer ink for thermal transfer recording (especially dye transfer type thermal transfer recording), a thermal transfer recording sheet, and a thermal transfer recording method using the thermal transfer recording sheet. Background technique [0002] Dye transfer type thermal transfer recording is a recording method in which a thermal transfer sheet with a colorant layer is stacked on an image-receiving sheet with a dye-receiving layer on the surface, and the colorant layer is contained on a base film. The formed thermal transfer dye; heat the thermal transfer sheet to transfer the dye in the thermal transfer sheet to the image receiving sheet, thereby realizing recording. Since this recording method can control the amount of dye transfer by heating energy, thereby realizing gradation expression, it is used for full-color image recording in video printers and the like. [0003] In this dye transfer type thermal t...
