熱転写印写装置に使用する熱転写インク媒体に関する。Description: TECHNICAL FIELD The present invention relates to a thermal transfer ink medium used in a thermal transfer printing apparatus that forms an image by controlling application of thermal energy.
（従来の技術） 小型低価格の印写装置として熱転写印写装置は広く商品
化されている。(Prior Art) A thermal transfer printing apparatus has been widely commercialized as a small-sized and low-cost printing apparatus.
この装置に用いる熱転写インク媒体は、第５図に示した
ように、耐熱性の支持層61と色材の含有した熱可塑性の
インク層62で構成される。As shown in FIG. 5, the thermal transfer ink medium used in this apparatus is composed of a heat resistant support layer 61 and a thermoplastic ink layer 62 containing a coloring material.

色素がぬけるといった問題があった。However, with this type of paper, paper with poor surface smoothness,
The transfer efficiency was poor with respect to paper or film having a poor chemical affinity with the hot melt ink or the heat sublimable dye, and the image quality was deteriorated. That is, in the case of the heat-meltable ink, as shown in FIG. 6, on the paper 73 having a poor surface smoothness, the ink which is not in contact with the transfer target paper at the time of applying the heat becomes a transfer failure and becomes a thermal transfer ink medium. Remains on the side (74), which is a factor that deteriorates the image quality, and in the case of thermal sublimation ink, dyeing is possible with the exception of special paper that has a color development layer with excellent chemical affinity for sublimation dyes on the surface. There was a problem that it was insufficient or that the dye was removed from the paper once dyed.
このような問題点は、転写ドットの解像度が高くなった
りに特に顕著で、完全に転写しないドットの発生率が高
くなる。Such a problem is particularly remarkable when the resolution of transferred dots is high, and the generation rate of dots that are not completely transferred is high.

体を汚す、いわゆる地汚れを起こすという問題を有して
いた。In the prior art, the pressing force of the thermal head causes the ink and the transfer medium to come into contact with each other with a strong force during transfer, so that the ink in the non-pixel portion is scraped off by the unevenness of the fibers of the paper and stains the transfer medium. It had a problem of causing dirt.

要であり、このために、インク層12とインク転写層13の
界面に分離層14を設ける必要がある。The ink transfer layer 13 is mainly composed of a thermoplastic organic substance or a cross-linking type organic substance, and is a transparent or colored thin film as necessary. As the component, a wax, a polymer, or the like, which is similar to the above-described ink, can be used alone or as a mixture, and it is preferable that the compatibility with the dye, pigment or binder of the ink when heat is applied is excellent. The ink transfer layer 13 needs to be peelable in a film state from the ink layer 12 at room temperature, and the components of each layer are incompatible at the interface in a state where the films are laminated, In addition, they must not be compatible when stored. That is, the dye, pigment or ink in the ink diffuses or adheres to the ink transfer layer in the heat application part, and the dye diffusion or the ink transfer (transfer) does not occur in the applied part. Therefore, it is necessary to provide the separation layer 14 at the interface between the ink layer 12 and the ink transfer layer 13.

They are compatible with each other to form a latent image s. Then, the thermal transfer ink medium on which the latent image is formed is removed by the peeling roller.
The heat-resistant support layer 11 and the ink layer 12 and the ink transfer layer 13 in the non-image portion 22 are peeled off by the 28 to form a visible image, and the ink transfer layer 13 is heated by the heat roller 29 to transfer the medium to be transferred. It is fixed on 28 Sa.

できる。 (Effects of the Invention) As described above, according to the present invention, a thermally activated ink layer is provided on one surface of a heat-resistant support layer, and the ink layer can be peeled from the ink layer at room temperature. Since the thermal transfer ink medium is composed of the ink transfer layer that is compatible with and softens, this type of thermal transfer ink medium can be configured to be extremely thin and capable of transferring with a small amount of heat energy, and the ink Due to the ink transfer function of the transfer layer and the function of fixing to the transfer medium, high-quality characters, figures, etc. not only for the transfer medium having poor surface smoothness but also for the transfer medium having poor chemical affinity. Can be transfer-molded, and furthermore, by interposing this ink transfer layer, direct contact between the ink layer and the medium to be transferred is eliminated, and the ink scraped by the irregularities of the fiber It is possible to prevent the surface of the medium to be transferred from being soiled.
