(Conventional technology and its problems) Conventionally, various thermal transfer methods are known. Among them, a sublimable dye is used as a recording agent, and this is carried on a base sheet such as paper or a plastic film, and a thermal transfer sheet is used. age,
Methods for forming various full-color images on a transfer material such as paper or plastic film provided with a dye receiving layer have been proposed. In this case, a thermal head of a printer is used as a heating means, and a large number of color dots of three or four colors are transferred to the material to be transferred by heating for a very short time,
The multicolor dots reproduce a full-color image of a document.

The image formed in this way is very clear because the coloring material used is a dye, and is excellent in transparency, so that the obtained image is excellent in the reproducibility and gradation of intermediate colors. It is possible to form a high-quality image which is similar to an image by offset printing or gravure printing, and is comparable to a full-color photographic image.

However, the transfer material on which an image can be formed by the above method is limited to a dye-dyeing plastic sheet or a paper provided with a dye-receiving layer in advance, and an image can be directly formed on ordinary plain paper. There is no problem. Of course,
Even if it is a general plain paper, if the receptor layer is formed on the surface, image formation is possible, but this is generally costly, for example, postcards, memos, stationery, report paper, etc. It is difficult to apply to a general ready-made transfer receiving material as described above.

However, when the receiving layer is transferred using the receiving layer transfer sheet as described above, there is little problem in the case where the material to be transferred is a processed paper having a smooth surface. In this case, since the fibers are exposed on the surface and lack the smoothness of the surface, the transfer of the receiving layer is not performed uniformly, so that an image formed on the receiving layer has white spots and chips,
There is a problem that a high quality image cannot be obtained.

These problems are enough to fill the surface irregularities of the paper, for example,
It is thought that this does not occur if the receiving layer is thickened to about 20 to 30 μm, or even if an intermediate layer is provided on the surface of the receiving layer, but in reality, if the receiving layer is thickened or the intermediate layer is laminated, the Problems such as a decrease in thermal efficiency, defective foil cutting, and uneven film thickness occur, and it is practically difficult to transfer the receiving layer itself, and the above problem cannot be solved.

On the other hand, a dye layer ink having the following composition was prepared, and applied to a 6 μm-thick polyethylene terephthalate film having a heat-resistant treatment on the back side by a wire bar so that a dry coating amount was 1.0 g / m 2 , and further dried. After a few drops of silicone oil (X-44003A, manufactured by Shin-Etsu Silicone Co., Ltd.) were dropped on the back surface with a dropper, it was spread over the entire surface and coated on the back surface to obtain a thermal transfer sheet.

(Effects) According to the present invention as described above, when the receiving layer coating liquid containing a foaming agent is coated on the surface of the coarse transfer receiving material, and then heated and foamed to form the receiving layer, the resulting layer is produced. The receiving layer becomes thicker due to the bubbles, and the surface unevenness is severe, so that a good receiving layer cannot be formed.

On the other hand, when the receiving layer of the receiving layer transfer sheet is coated with a coating liquid containing a foaming agent and heated to contain bubbles in the receiving layer, the surface of the receiving layer has irregularities in the same manner as described above. Although it is intense, when the receiving layer is transferred, it is crushed by the printing pressure and fills the surface irregularities of the paper, and a smooth and thin receiving layer is transferred and formed. Even with coarse paper, good image formation with no white spots or chipping Becomes possible.
