号公報に示された染料等を知られている。In recent years, thermal transfer printers have become popular as printers that make hard copies of images on various displays. A thermal transfer sheet and a recording medium are used as recording materials for this printer. A thermal transfer sheet is a sheet in which an ink layer containing a dye (hereinafter referred to as a sublimable dye) that has the property of sublimating, evaporating, or diffusing and transferring to a recording medium by heat is provided on a substrate. Compared to a type of thermal transfer sheet (referred to as a melting type) in which the ink melts or softens due to heat and transfers onto the recording medium, this thermal transfer sheet can be easily transferred with the amount of heat energy applied without reducing resolution. It is characterized by being able to control the density and making it easy to obtain prints with excellent image quality similar to silver halide photography. An example of such a thermal transfer sheet is JP-A-60-101087.
Many publications such as No. 1 are known. In addition, the sublimable dye used in this thermal transfer sheet includes the dye used in the above publication, and the dyes used in JP-A-60-30391 and JP-A-60-30392.

FIG. 1 is a cross-sectional view of the thermal transfer sheet 1, which includes a heat-resistant slipping layer 2 on one side of a base 3. An ink layer 4 containing a sublimable dye and a binder is provided on the other side.

The silicone was dried and left at a temperature of 100° C. for 5 minutes to harden the silicone, thereby forming a heat-resistant slipping layer 2 having a thickness of about 0.2 μm.

The recording sensitivity characteristics of the thermal transfer sheet were measured using the recording medium in the 0 paper ink set VY-S100. In order to determine the temperature, the VY-50 was partially modified so that the power supply to the thermal head could be controlled from the outside. In other words, the energizing time per printing line can be changed from 0 to 15 m5.
It is now possible to control at ms intervals. In this way, the energizing time per print line is 1m from 0 to 15m5.
The energization time and reflection density of the printed image obtained on the recording medium by changing every s (reflection densitometer D manufactured by Dainippon Screen)
(measured with M-400) is shown in Figure 2.

ることができる。Compared to similar characteristics of the thermal transfer sheet of Comparative Example 1 using a conventionally used dye, which will be described later, a very high reflection density was obtained at any current application time. That is, in order to obtain a printed image with high recording sensitivity and the same reflection density using the thermal transfer sheet of this example, the energization time per line may be shorter than when using the thermal transfer sheet of Comparative Example 1, or the energization time may be shorter than when using the thermal transfer sheet of Comparative Example 1. If the times are the same, the voltage applied to the thermal head will be lower. Therefore, recording time and power consumption can be reduced.

できる。In addition, we measured the reflection spectrum of the obtained print image with a reflection density of approximately 1°3 (using Hitachi Color Analyzer Model 607) and calculated the complementary dominant wavelength (hue). The color was appropriate. Therefore, by applying the thermal transfer sheet of this example to a thermal transfer sheet having an appropriate yellow sublimable dye-containing ink layer and a cyan color sublimable dye-containing ink layer,
It is possible to provide a thermal transfer sheet that can produce clear full-color images.

26) Thermal transfer sheets of Comparative Examples 2 and 3 were prepared in the same manner as in Example 1 except that 1 part by weight (Comparative Example 3) was used. Using these thermal transfer sheets, the relationship between current application time and reflection density and reflection spectrum were measured in the same manner as in Example 1. Table 2 shows the reflection density and complementary color dominant wavelength when the current application time was 5.10.15 m5.
記録画像の色相はマゼンタ色としていずれも適切である
が、実施例と比べると記録感度が低い。The hue of the recorded image is magenta, which is appropriate, but the recording sensitivity is lower than in the example.

The reflection density and complementary color dominant wavelength when the current application time was 5.10.15 m5 are shown in Table 2 (Example 2 is also listed).
いずれの実施例の熱転写シートも比較例のそれと比べる

画像を記録することができる。In addition, the thermal transfer sheet of Example 10 has an appropriate hue of the recorded magenta color, and as a thermal transfer sheet for full-color recording, it is possible to produce clear full color by adding an ink layer containing appropriate yellow sublimation dye and cyan dye. Images can be recorded.
本発明の熱転写シートは特定化学構造の染料をインク層
中に含有しているので、被記録体上に記録される画像の
反射濃度が高く、記録感度が高い。Since the thermal transfer sheet of the present invention contains a dye having a specific chemical structure in the ink layer, the image recorded on the recording medium has a high reflection density and high recording sensitivity.
従って、熱転写記録に際し、本発明の熱転写シートを用
いると記録時間や記録エネルギを低減できるという効果

できる。In addition, a thermal transfer sheet using a dye of an appropriate hue for magenta color can be produced by providing an ink layer containing an appropriate yellow sublimable dye and a cyan sublimable dye on the substrate adjacent to the magenta ink layer. It can be provided as a thermal transfer sheet for creating clear, full-color images with high recording sensitivity.
