Hydrocarbons and the like can be used, but when a water-soluble or water-dispersible aqueous resin is used as the binder, water or water and a mixture of the above solvents can also be used. Further, as a method of applying the ink onto the substrate, a reverse roll coater, a gravure coater, a rod coater, an air doctor coater, or the like can be used (Yuji Harasaki, Maki Shoten, 1979, "Coating method". )). The amount of ink applied may be in the range of 0.1 to 5 g / m ² after drying.

More specific examples will be shown below, but the present invention is not limited to these examples.

Example 1 A heat resistant slipping layer was provided on the lower surface of a 6 μm PET film to prepare a substrate. Dye No. 1 listed in the above Tables 1, 2, 5 on the top surface
-145,2-37,5-4 2g each and polycarbonate (Teijin Kasei Co., Ltd. Teijin Panlite L1250) 4g dissolved in dichloromethane 25g ink obtained by magenta (No. 2-3
7), yellow (No. 5-4) and cyan (No. 1-145) were applied in this order with a wire bar and dried with hot air to obtain a three-sided transfer member.

Next, 20 g of water-based polyester resin (Toyobo Co., Ltd. Bayronal MD1200), colloidal silica (Nissan Chemical Co., Ltd. Snowtex 40) 40 on top of white synthetic paper made of PET.
A coating liquid of g was applied with a wire bar to obtain an image receptor.

The transfer body and the image receiving body were brought into close contact with each other so that their coated surfaces face each other, and recording was performed with a thermal head. The recording conditions are as follows.

Cotton density in main scanning and sub scanning: 4 dots / mm Recording power: 0.7 W / dot Head heating time: 8 msec The reflection recording densities of magenta, yellow, and cyan were 1.6, 1.5, and 1.8, respectively. In addition, the density characteristics when the heating time of the head is changed from 0 to 8 msec
Shown in the figure. Further, an image was recorded by superposing magenta, yellow, and cyan in this order on the same image receiver by using the transfer body having three surfaces of magenta, yellow, and cyan.
Similarly, a black density characteristic as shown in FIG. 2 was obtained. Further, when the respective densities of black were plotted on the chromaticity diagram shown in FIG. 3, they were all concentrated near the point indicated by B. When magenta, yellow, and cyan colors were appropriately overlapped to prepare a mixed color, chromaticity points of the respective colors as shown in FIG. 3 were obtained. This is very close to color printing.

Example 2 As dyes, cyan No. 1-145 1g and 1-146 1g, magenta No. 2-37 2g, and yellow No. 4-19 0.6g and 5-4 1.2g were used. In the same manner as in Example 1, 4 g of polycarbonate was dissolved in 25 g of dichloromethane, and in the same manner, a three-sided transfer member in the order of yellow, magenta, and cyan was obtained. Recording was performed in the same manner as in Example 1 by changing the color order of yellow, magenta, and cyan, and the same preferable result as in Example 1 was obtained.

Example 3 Dyes were used in the same manner as in Example 1 using No. 1-61 g and 1-147 1 g for cyan, No. 2-26 2 g for magenta, and No. 6-37 2 g for yellow. Dissolved in 25 g of dichloromethane together with 4 g of polycarbonate, a transfer member having three surfaces in the order of yellow, magenta and cyan was obtained in the same manner. Recording was performed in the same manner as in Example 1 by changing the color order of yellow, magenta, and cyan, and the same preferable result as in Example 1 was obtained.

Example 4 Nos. 1-12 and 1-72 as cyan dyes, 0.5 g each, magenta dyes, Nos. 2-1 and 2-3, 0.5 g each, and yellow dyes No. 3- 0.3g for 12, 4-19, 5-4
Was dissolved in 25 g of dichloromethane together with 4 g of polysulfone (P-1700, manufactured by Nissan Chemical Industries, Ltd.) to prepare a black ink, which was used to obtain a black transfer member. When recording was performed in the same manner as in Example 1, as in the case of recording with three colors superimposed in Example 1, the concentration was concentrated in the vicinity of point B on the chromaticity diagram.

Further, regarding the recorded images obtained in Examples 1 to 4, JIS
When the fastness to sunlight was tested in accordance with the LO841 standard, values of 4 to 5 grades were obtained, and it was judged that it could be sufficiently practically used. Further, when the recorded image was left in an atmosphere of 60 ° C, 70 ° C, 80 ° C (60% relative humidity) to evaluate the dark fading property, there was almost no change at 60 ° C, 60% RH and 300 hours, and Aurenius When the life expectancy at which the concentration decreased by 10% was estimated from the plotting method, the result was several decades or more.

It was also found that the storage stability of the transfer itself could be suppressed to a fluctuation of 10% or less even if it was left at room temperature for 2 years.

As described above, the dye transfer body of the present invention can obtain color reproducibility of each color including black and image quality comparable to that of color printing in saturation density / halftone, and can impart high weather resistance. It was
