ることである。(Prior art) Inkjet methods, thermal transfer methods, etc. have been developed as methods for providing excellent monochrome or full-color images easily and at high speed in place of conventional general printing methods. The most superior method is the so-called sublimation thermal transfer method, which uses sublimable dyes, as it has excellent continuous gradation properties and can produce full-color images comparable to color photographs. The thermal transfer sheet used in the above-mentioned sublimation type thermal transfer method has a dye layer containing a sublimable dye formed on one side of a base sheet such as a polyester film, and a dye layer containing a sublimable dye on one side of the base sheet to prevent the thermal head from sticking. A heat-resistant slip layer is generally used on the other side. The dye layer surface of such a thermal transfer sheet is placed on a transfer material having a dye-receiving layer made of polyester resin, vinyl chloride resin, etc., and the dye layer in the dye layer is heated imagewise from the back side of the thermal transfer sheet using a thermal head. The dye transfers to the transfer material to form the desired image. Thermal transfer sheets such as those described above are being used for various purposes, and in particular, they can easily and conveniently form facial photographs with excellent gradation directly on the surface of synthetic resin sheets such as vinyl chloride resin. Since it is possible, I
It is now used to create D cards. However, since the information recorded on cards, such as characters, symbols, and barcodes, requires uniform, high-density black rather than gradation, these types of information are recorded using heat-melting thermal transfer sheets. It is desirable to record information, and for this purpose, a mixed type thermal transfer sheet has been proposed in which a sublimation type dye layer and a heat melting type ink layer are sequentially provided on the surface of the same base sheet (Unexamined Japanese Patent Publication No. 1986-9
(See Publication No. 574). With these mixed-type thermal transfer sheets, excellent gradation images such as facial photographs and high-density single-color images such as letters and symbols can be simultaneously formed using the same printer. (Problem to be Solved by the Invention) In the mixed type thermal transfer sheet as described above, in the sublimation type dye layer, only the dye transfers to the transfer material, and the binder remains on the base sheet side. Good adhesion is required between the layer and the base sheet. On the other hand, in the case of a hot-melt type ink layer, the entire thickness of the ink layer must be transferred to the transfer material, that is, the ink layer and the base sheet must be bonded together. Good releasability is required between the material and the material sheet. To meet these demands, there is a method in which a heat-melt ink layer is formed using a base sheet with good releasability, and an adhesive layer is formed in the area where a sublimation type dye layer is to be formed. Alternatively, it is conceivable to form a release layer on a base sheet on which an adhesive layer has been formed, and then form a hot-melt ink layer thereon, but when such an adhesive layer is formed, sublimation Thermal transfer of a sublimable dye layer generally requires greater thermal energy than transfer of a heat-fusible ink layer, which significantly reduces the thermal sensitivity of the sublimable dye layer, making it impossible to form good gradation images. There's a problem. For this reason, it is necessary to provide the adhesive layer as thin as possible, but until now it has been difficult to provide a uniform adhesive layer with a submicron thickness, resulting in uneven printing and abnormal transfer of the dye layer (dye The problem is that the entire layer is transferred). Therefore, an object of the present invention is to provide a thermal transfer sheet that can easily form images with excellent gradation and high-density images such as characters and symbols at the same time without causing the above-mentioned problems.

なる。The dye layer to be formed may be formed by selecting one color from among the above dyes when the desired image is monochrome, or
If the desired image is a full color image, for example,
Appropriate cyan, magenta, and yellow (and black, if necessary) are selected to form yellow, magenta, and cyan (and black, if necessary) dye layers. In the present invention, in addition to the dye layers described above, a heat-fusible ink layer is formed in parallel to these dye layers. Although the order of formation is not particularly limited, for example, yellow, magenta, and cyan dye layers and a black heat-melting ink layer are sequentially formed on an A4 size plate. These ink layers are formed from hot-melt binders colored with dyes or pigments. The preferred colorant is carbon black, but is not limited thereto, and other dyes and pigments of each hue can also be used. The binder is a thermoplastic resin with a relatively low melting point, wax, or a mixture thereof, but it is preferable to select it in consideration of adhesiveness to the material to be transferred.For example, if the material to be transferred is an ID card, etc. In the case of vinyl chloride resin, which is widely used in polyester resins, thermoplastic resins such as (meth)acrylic esters, vinyl chloride/vinyl acetate copolymers, ethylene/vinyl acetate copolymers, and polyesters are suitable. Methods for forming a hot-melt ink layer on a base sheet include hot melt coating, hot lacquer coating,
Examples include gravure coating, gravure reverse coating, roll coating, and many other methods of applying the above ink. The thickness of the ink layer formed should be determined to balance the required density and thermal sensitivity, and is preferably in the range of 0.2 to 3.0 μm, so that the ink layer is too thin. If the foil is too thick, the reflection density of the transferred image will be insufficient, and on the other hand, if the foil is too thick, the foil will not cut easily during printing and the sharpness of the printed image will deteriorate. In the present invention, it is preferable to form a release protective layer on the surface of the substrate in advance when forming the ink layer. This release protective layer improves the releasability of the ink layer, is transferred together with the ink layer, becomes a surface protective layer of the transferred image, and improves the abrasion resistance of the transferred image.
Such a peelable protective layer is made of, for example, (meth)acrylic resin, silicone resin, fluorine resin, cellulose resin such as cellulose acetate, styrene resin, epoxy resin,
Examples include polyvinyl alcohol and the like to which wax, organic pigments, inorganic pigments, etc. are added, or waxes such as polyethylene wax, carnauba wax, paraffin wax, etc., and the thickness of the peelable protective layer formed is preferably The foil is in the range of 0.2 to 1.5 μm, and if it is too thin, the protective effects such as scratch resistance will not be sufficient, while if it is too thick, the foil will not easily cut during printing. Further, in the present invention, it is preferable to further form a heat-sensitive adhesive layer on the ink layer, and this adhesive layer is also selected in consideration of adhesion to the transfer material. For example, when the transfer material is vinyl chloride. When the card base material is made of a resin, it is preferable to use a thermoplastic resin having good adhesive properties as described above. The thickness of the adhesive layer formed is preferably 0.
If it is too thin, it will be difficult to obtain the desired adhesiveness, while if it is too thick, it will be difficult to cut the foil during printing.

トを得た。Further, in the present invention, it is preferable to provide a heat-resistant slipping layer on the back surface of the base sheet in order to prevent the thermal head from sticking during printing and to improve its slipperiness. The transfer material used to form an image using the thermal transfer sheet as described above may be any material as long as its recording surface has dye receptivity to the above-mentioned dyes. In the case of paper, metal, glass, synthetic resin, etc. that do not have any properties, a dye-receiving layer may be formed on at least one surface thereof. In particular, the thermal transfer sheet of the present invention is suitable for producing cards made of polyvinyl chloride resin, and gradation images and images made of a sublimation dye layer can be printed on these card base materials without forming a special dye-receiving layer. Characters, symbols, barcodes, etc. made of a layer of fusible ink can be printed directly. A particularly preferred card base material in the present invention is one containing 0.1 to 10 parts by weight, more preferably 1 to 5 parts by weight of a plasticizer per 100 parts by weight of polyvinyl chloride, and the card base material is one that contains a plasticizer in an amount of 0.1 to 10 parts by weight, more preferably 1 to 5 parts by weight. It has sufficient dyeability against synthetic dyes and good adhesion even when resistant to meltable inks. In a preferred embodiment of the present invention, in addition to the above plasticizer, O. l to 5
By including 1 part by weight of a lubricant, even if a relatively large amount of plasticizer is included in polyvinyl chloride, for example, 1 to 5 parts by weight, there will be no blocking with the thermal transfer sheet during transfer, and there will be no gain. We have found that the dyeability of the card base material with sublimable dyes is further improved. The above-mentioned vinyl chloride resin card base material is prepared by blending the above-mentioned necessary components, and then using a well-known forming method such as a calendering method, an extrusion method, etc., to obtain a
It is obtained by forming a sheet into a sheet with a thickness of about 1 mm to 1 mm, and it may be a sheet before being cut into a so-called card size or a sheet cut into a card size. Further, these card base materials may have a single-layer structure or may have a multi-layer structure, for example, a center core containing a white pigment and a transparent resin layer provided on at least one side of the center core. Of course, the thermal transfer sheet of the present invention is not limited to the production of cards made of vinyl chloride resin, and is useful not only for other card base materials such as polyester, but also for transfer materials other than cards such as passports. It is also useful for creating various printed materials such as catalogs that require gradation images and monochromatic images such as characters, symbols, and barcodes at the same time. The means for applying thermal energy used when performing thermal transfer using the above-mentioned thermal transfer sheet and the above-mentioned recording material are as follows:
Any conventionally known application means can be used; for example, by controlling the recording time using a recording device such as a thermal printer (for example, Video Printer VY-100 manufactured by Hitachi), a A desired image is formed by applying thermal energy. (Effects) According to the present invention as described above, by using a polyester film treated for easy adhesion as a base sheet, images such as clear gradation images and clear characters can be formed with one type of thermal transfer sheet. A thermal transfer sheet is provided that is capable of
Moreover, by using the thermal transfer sheet, an excellent card can be provided. (Example) Next, the present invention will be explained in more detail with reference to Examples and Comparative Examples. In the text, parts or percentages are based on weight unless otherwise specified. Example 1 A heat-resistant slipping layer was formed on the back surface as a base sheet, and 3. Apply a toluene solution of acrylic resin consisting of 10 parts of TR-64 varnish (manufactured by Dainippon Ink ■) and 40 parts of toluene to a dry thickness of 0.7 μm, leaving an area the size of 84 individual plates. It was then dried to form a peelable protective layer on an A4 size plate. Next, black ink consisting of 1 part MSF (manufactured by Toyo Ink ■) and 40 parts toluene was applied to the surface to a dry thickness of 2 μm.
A heat-melting ink layer is formed by applying and drying the ink layer, and then TR-64 varnish (manufactured by Dainippon Ink) is applied on the surface.
A toluene solution of acrylic resin consisting of 10 parts and 40 parts of toluene was applied and dried to a dry thickness of 0.5 μm to form a heat-sensitive adhesive layer. Furthermore, between the above ink layers, the following three colors of ink composition for forming a dye layer were gravure printed on A4 size paper so that the dry thickness was 1.0 g/rrr.
