（産業上の利用分野）
本発明は受容層転写シートに関し、更に詳しくは表面が

The present invention relates to a layer transfer sheet.

ものである。(Prior art and its problems) Conventionally, various thermal transfer methods are known, but among them, a thermal transfer sheet is created by using a sublimable dye as a recording agent and supporting it on a base sheet such as paper or plastic film. There have been proposed methods for forming various full-color images on transfer materials such as paper and plastic films provided with dye-receiving layers. In this case, the thermal head of the printer is used as a heating means, and by extremely short heating, 3
A large number of color dots of one color or four colors are transferred to a transfer material, and a full-color image of an original is reproduced using the multicolor color dots.
この様に形成された画像は、使用する色材が染料である

形成可能となっている。The images formed in this way are very clear because the coloring material used is dye, and they have excellent transparency, so the images obtained have excellent intermediate color reproducibility and gradation, and are It is possible to form high-quality images that are similar to images produced by offset printing or gravure printing, and comparable to full-color photographic images.
しかしながら、上記方法で画像形成が可能な被転写材は

高であり、例えば、葉書、メモ、便箋、レポート用紙等
の如き一般的な既製の被転写材には応用困難である。However, the transfer materials on which images can be formed using the above method are limited to plastic sheets that can be dyed or paper that has a dye-receiving layer in advance, and images cannot be directly formed on general plain paper. The problem is that there is no. Of course, it is possible to form images on ordinary plain paper if a receptive layer is formed on its surface, but this is expensive for fishing on a boat, for example, for postcards, memos, stationery, etc. It is difficult to apply this method to general ready-made transfer materials such as report paper.
この様な問題点を解決する方法として、普通紙等の既製
品の被転写材に画像を形成し様とする場合、その必要部
分のみに染料受容層を手軽に形成する方法として、受容
層転写シートが知られている（例えば、特開昭６２−２
６４９９４号公報参照）。To solve these problems, when an image is to be formed on a ready-made transfer material such as plain paper, a dye-receiving layer can be easily formed only in the necessary areas using receptor layer transfer. sheets are known (for example, JP-A-62-2
(See Publication No. 64994).
しかしながら、以上の如き受容層転写シートを使用して

ことが出来ないという問題がある。However, when transferring the receptive layer using the above-mentioned receptive layer transfer sheet, there are few problems when the transfer material is processed paper with a smooth surface, but when it is a general paper such as the above, the surface Because the fibers are exposed and the surface lacks smoothness, the receiving layer is not transferred uniformly, resulting in white spots and chips in the image formed on the receiving layer, making it difficult to obtain high-quality images. The problem is that it can't be done.
これらの問題は紙の表面凹凸を埋める程度、例えば、２
０〜３０μｍ程度に受容層を厚（したり、更には受容層
表面にクッション層を設ければ発生しないと考えられる
が、現実には受容層を厚くしたり、クッション層を積層
すると、転写時の熱効率の低下、箔切れ不良、膜厚不均
一等の問題が生じて、受容層自体の転写が事実上困難で
あり、上記問題の解決にはならない。These problems are limited to the extent to which the unevenness of the paper surface is filled, for example, 2
It is thought that this problem will not occur if the thickness of the receptive layer is set to about 0 to 30 μm, or if a cushion layer is provided on the surface of the receptive layer, but in reality, if the receptive layer is made thicker or a cushion layer is laminated, problems may occur during transfer. Problems such as a decrease in thermal efficiency, poor foil cutting, and non-uniform film thickness occur, making it virtually difficult to transfer the receptor layer itself, which does not solve the above problems.
従って、本発明の目的は、表面が平滑でないラフ紙等に
も高品質及び高濃度画像を形成することを可能とする受
容層転写シートを提供することである。Therefore, an object of the present invention is to provide a receptor layer transfer sheet that makes it possible to form high-quality and high-density images even on rough paper or the like whose surface is not smooth.
（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.
即ち、本発明は、基材シートの一方の面に染料受容層と

徴とする受容層転写シートである。That is, the present invention is a receptor layer transfer sheet characterized in that a dye receptor layer and a cushion layer are releasably provided in parallel on one surface of a base sheet.

高品質画像が形成される。(Function) The receiving layer is provided thinly, and the cushioning layer is also provided thinly in parallel.
By subsequently transferring the receptive layer thereon, even if the material to be transferred has a rough texture, the unevenness can be filled with the cushion layer and the untransferred portion of the receptive layer can be eliminated.
Therefore, a high quality image without white spots or chips is formed on the receptor layer thus formed.

層の形成は不要である。It is preferable to form a release layer on the surface of the base sheet prior to forming the receptor layer. Such a release layer is formed from a release agent such as wax, silicone wax, silicone resin, fluororesin, or acrylic resin. The formation method may be the same as the method for forming the receptor layer described later, and a thickness of about 0.5 to 5 μm is sufficient. If a matte receiving layer is desired after transfer, the surface can be made matte by incorporating various particles into the release layer or by using a base sheet whose surface on the release layer side has been matt treated. Of course, if the base sheet as described above has appropriate releasability, it is not necessary to form a release layer.
