から色素がぬけるといった問題があった。However, in this type of device, 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 hot melt ink, the fifth
As shown in the figure, on paper 73 with poor surface smoothness, ink that is not in contact with the transfer paper when heat is applied becomes transfer failure and remains on the thermal transfer ink medium side (74), which is a factor that deteriorates the image quality. In addition, in the case of thermal sublimation ink, dyeing is inadequate, or from paper that has been dyed once, except for special paper that has a developer layer with excellent chemical affinity for sublimation dyes on the surface. There was a problem that the dye would come off.
このような問題点は、転写ドットの解像度が高くなった
場合に特に顕著で、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.

上がり、印字スピードを低下させてしまうという問題を
派生させていた。In the conventional technology, in order to increase the transfer efficiency to the transfer paper with poor surface smoothness, attempts have been made to increase the thickness of the ink layer or increase the melt viscosity, which increases the printing energy and increases the printing speed. It caused the problem of lowering it.

いう問題を有していた。Further, in the conventional device, since the ink and the medium to be transferred come into contact with the ink transfer paper with a strong force due to the pressing force of the thermal head, the ink in the pixel area is scraped off by the unevenness of the fiber of the paper and stains the ground of the paper. There was a problem of causing a phenomenon, so-called background stain.

離層16を形成してある。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, the same wax as in the above-mentioned ink, polymer or the like can be used alone or as a mixture, and it is desirable 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 from the ink layer 12 in a film state at room temperature, and the components of each layer are incompatible with each other in the laminated state and stored. Sometimes we have to make them incompatible. That is, the dye, pigment or ink in the ink is diffused or adhered to the ink transfer layer in the heat application portion, and the dye diffusion or the ink transfer (transfer) does not occur in the non-application portion. Therefore, at the interface between the ink layer 12 and the ink transfer layer 13, a 10% solution of a fluorinated surfactant (diluted with toluene) is added at 1 g / m 2
The separation layer 16 is formed by coating with or drying.

It is preferable to use a mixture of natural rubber, SBR, polyvinyl ether, polyacrylic ester and the like with a tackifying resin such as polytempene, rosin and petroleum hydrocarbon.

成される。When heat corresponding to characters or the like is applied from the heat-resistant support layer 11 side on the platen 28 to the thermal transfer ink medium thus configured by the thermal head 21, the ink layer 12 at this portion
Since the ink transfer layer 13 and the ink transfer layer 13 are compatible with each other, and the ink forms a latent image without being diffused or adhered by the separation layer 16 interposed therebetween, the transfer medium 27 is directly transferred through the adhesive layer 14 in this state. When it is attached to the upper surface and the layer 22 composed of the ink layer 12 and the ink transfer layer 13 together with the heat resistant support layer 11 is peeled off, characters, figures and the like are formed as a visible image on the transfer medium 27.

Since an ink transfer layer which can be peeled off and which is compatible with this ink layer by heat application is formed, and an adhesive layer having adhesiveness at room temperature is further laminated thereon to form a thermal transfer ink medium, a separation layer Not only can a clear image be formed without diffusing the ink by the above, but heat can be applied to the thermal transfer ink medium according to the characters, etc., and if this is directly adhered to the transfer medium, it will form an ink layer. The latent image such as characters formed by compatibility with the ink transfer layer can be directly transferred as a visible image onto the transfer medium, and the characters can be transferred onto the transfer medium by a simple operation without using label paper. , It is possible to transfer figures and the like.
