した方式と考えられる。In recent years, with the spread of information terminals such as personal computers, televisions, VTRs, video discs, etc. and the use of color displays, the demand for printers that output these still images as color images has increased. Recording methods for color printers include electrophotography, inkjet, and thermal transfer, but thermal transfer is the most commonly used method because it is noiseless and easy to maintain. . This thermal transfer method uses a thermal transfer recording sheet in which pigments or dyes are bound with heat-melting wax, and a method that applies conventional sublimation transfer printing technology, using disperse dyes that are relatively easy to sublimate as a binder. There is a sublimation transfer type that uses a thermal transfer recording sheet bound with resin. Among these, the heat-melting transfer type transfers the pigment or dye to the image receptor together with the wax melted by thermal energy from a thermal head, etc., so it is difficult to obtain the halftones necessary for image quality, and it is good because of the transferred wax. The disadvantage is that it is difficult to obtain a hue. On the other hand, with the sublimation transfer type, only the sublimable dye is sublimated and transferred by the thermal energy of a thermal head, etc., and excellent hues and intermediate tones can be easily obtained because the sublimable dye sublimes in response to the thermal energy. This method has the advantage of being able to control the gradation at will, and is considered to be the most suitable method for a full-color printer.

が使用されている。As a thermal transfer image receptor used in this sublimation transfer type transfer method, plain paper can be used as described in Japanese Patent Application Laid-open No. 15446/1982, but plain paper alone does not have sufficient color density. Moreover, it is not preferable because it has poor fixing properties for sublimable dyes and economical discoloration is also significant. For these reasons, Japanese Patent Application Laid-Open No. 57-107885
As described in the publication, a dyeing resin layer made of a thermoplastic resin, typified by a saturated polyester resin, which can be effectively dyed with sublimable dyes, is provided on a base material. ing.

であった。However, unlike heat-fusion transfer, the sublimation transfer type transfer method forms an image by sublimation transfer of sublimable dye, and since there is no metallic sublimable dye with metallic luster, it forms a metallic image with metallic luster. That was difficult.

となる。The thermal transfer image receptor of the present invention basically consists of three layers: a dyeing resin layer (1), a metal foil layer (2), and a base material (3), as shown in FIG.
Consists of layered structure. Then, as shown in Fig. 2, a thermal transfer recording sheet consisting of a substrate (4) and a coloring material layer (5) containing a sublimable dye is placed on top of the substrate (4) and pressed using a thermal head (6) and a platen roller (7). while the thermal head (
6), the sublimable dye in the color material layer (5) is sublimated and transferred to the dyeing resin layer (1) of the thermal transfer image receptor, thereby forming an image. When forming an image by such a method, if the thermal transfer image receptor of the present invention is used, a metallic image with metallic luster can be obtained because the metal foil layer (2) is provided in the image receptor. It will be obtained.

恐れがある。To explain the present invention in more detail, the metal foil layer (2) used in the present invention can be made of various metals or alloys, but aluminum and tin foils are particularly preferred. The thickness of the metal foil is 50 μm or more, preferably 2
If the thickness of the metal foil exceeds 50 μm, the rigidity of the thermal transfer image receptor becomes large, making it easy to run troubles, and the flexibility in the thickness direction becomes poor, making it difficult to connect the thermal transfer recording sheet with the thermal head. There is a risk that the image quality may become poor due to the interference, causing unevenness in the image or a decrease in sensitivity.
