の提供を［１的とする。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a thermal transfer image-receiving sheet, and more specifically, it forms a recorded image that is excellent in color density, sharpness, and various fastnesses, especially in storage stability and stain resistance. [1] To provide a thermal transfer image-receiving sheet that can perform the following steps.

である。(Prior Art) Various thermal transfer methods are conventionally known, and among them, a thermal transfer sheet is prepared by using an Ifr dye as a recording agent and supporting it on a base sheet such as a polyester film.
Various methods have been proposed for forming full-color images on image-receiving materials in which a dye-receiving layer is formed on a transfer material that can be dyed with a ascending dye, such as paper or plastic film. In this case, the printer's thermal head is used as a heating means, and a large number of three or four color dots are transferred to the transfer material by heating for a very short time, and the multicolor dots are used to print the original. It reproduces a full color image.

形成可能となっている。The images formed in this way are very clear and have excellent transparency because the coloring material used is dye, so the resulting images have excellent intermediate color reproducibility and gradation. It is possible to form high-quality images that are similar to images produced by conventional offset printing or gravure printing, and comparable to full-color photographic images.
（発明が解決しようとしている問題点）上記の如き熱転
写方法を仔効に実施する為には、熱転写シートの構成は
勿論、画像を形成する為の受像シートの構成も同様に重
要である。(Problems to be Solved by the Invention) In order to effectively carry out the thermal transfer method as described above, not only the structure of the thermal transfer sheet but also the structure of the image-receiving sheet for forming an image are equally important.
即ち、受像シートの染料受容層は染料の染着性が良好で
あり、且つ染着した染料をしっかりと固定する必要があ
る。That is, the dye-receiving layer of the image-receiving sheet must have good dyeability and must firmly fix the dye.
転写された染料の染着性を良好にする手段としては、染
着性の良好な樹脂から染料受容層を形成すればよいが、
染料染着性の良好な樹脂からなる染料受容層中では形成
された画像が保存中に滲み画像の保存性が劣るという問
題が生じる。As a means to improve the dyeability of the transferred dye, it is sufficient to form the dye-receiving layer from a resin with good dyeability.
In a dye-receiving layer made of a resin with good dye-dyeability, a problem arises in that the formed image bleeds during storage, resulting in poor image storage stability.
この現象は染料が染料受容層内で動き易い為であり、こ

その表面と接触する他の物品を汚染し易いという問題が
ある。又、この様な保存性及び汚染性の他にも熱転写時
に熱転写シートと受像シートが接着し、染料層が剥離す
るという問題もある。This phenomenon occurs because the dye moves easily within the dye-receiving layer, and when a resin with poor dye fixing properties is used, a high-density and highly clear image is formed, but the formed image There are also problems in that the dye has poor storage stability, and the dye bleeds out onto the surface and tends to contaminate other articles that come into contact with the surface. In addition to the storage stability and staining properties, there is also the problem that the thermal transfer sheet and the image-receiving sheet adhere to each other during thermal transfer, causing the dye layer to peel off.
上記の如き問題を解決する方法としては、染着した染料
が染料受容層内で移行しにくい樹脂を選択すればよいが
、この場合には染料の染着性が劣り、高濃度１１つ高鮮
明性の画像が形成出来ないという間通がある。A method to solve the above problems is to select a resin that does not allow the dye to migrate easily within the dye-receiving layer, but in this case, the dye's dyeability is poor, and the dye has a high density and high definition. There is a common misconception that sexual images cannot be formed.
上記２種の問題を同時に解決する方法としては、染料染
着性の良い樹脂と染料移行性の少ない樹脂を混合して使
用することが考えられるが、実際には両者の中間の性質
が表れ、問題解決の有効な４段とはならない。One possible way to solve the above two problems at the same time is to use a mixture of a resin with good dye stainability and a resin with low dye transferability, but in reality, properties intermediate between the two appear. This is not an effective four-step process for problem solving.
従って、本発明の目的は、昇華性染料を使用する熱転写
方法において、１分に濃度のある鮮明な画像を′ｊえ、
しかも形成された画像が優れた諸堅牢性、特に耐移行性
や耐汚染性を示す熱転写受像シートを提供することであ
る。Therefore, an object of the present invention is to produce a clear image with high density per minute in a thermal transfer method using a sublimable dye;
Moreover, it is an object of the present invention to provide a thermal transfer image-receiving sheet in which formed images exhibit excellent fastness properties, particularly migration resistance and stain resistance.
（問題点を解決する為の手段） 上記目的は以下の本発明によって達成される。(Means for solving problems) The above objects are achieved by the present invention as described below.
すなわち、本発明は、基材シートの少なくとも方の面に
染料受容層を形成してなる熱転写受像シートにおいて、
該染料受容層が少なくとの２種の非相溶性樹脂から形成
されていることを特徴とする熱転写受像シートである。That is, the present invention provides a thermal transfer image-receiving sheet in which a dye-receiving layer is formed on at least one surface of a base sheet,
The thermal transfer image-receiving sheet is characterized in that the dye-receiving layer is formed from at least two kinds of incompatible resins.

な染料受容層の形成が困難となるので好ましくない。Further, in the present invention, the above-mentioned incompatible resins are preferably selected and combined so that the difference in SP value between the two is in the range of 0.2 to 5. If the difference in SP value is less than 0.2, the phase separation between the two will be too small and good results will not be obtained, and if the difference in SP value exceeds 5, the solution of the mixture will be too gelled, resulting in poor dye reception. This is not preferred because it makes it difficult to form a layer.
