【発明の詳細な説明】
（産業上の利用分野）
本発明は複合熱転写シートに関し、更に詳しくは熱転写

る複合熱転写シートに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a composite thermal transfer sheet, and more particularly to a composite thermal transfer sheet capable of forming high-quality color images by a thermal transfer method.
（従来の技術及びその問題点）
従来、種々の熱転写方法が公知であるが、それらの中で
昇華性染料を記録剤とし、これを紙やプラスチックフィ

３色又は４色の多数の色ドツトを被転写材に転移させ、
該多色の色ドツトにより原稿のフルカラー画像を再現す
るものである。(Prior art and its problems) Conventionally, various thermal transfer methods are known, but among them, a thermal transfer sheet is produced by using a sublimable dye as a recording agent and supporting it on a base film such as paper or plastic film. year,
Various methods have been proposed for forming a full-color image on a transfer material such as paper or plastic film provided with a dye-receiving layer. In this case, a thermal head of the printer is used as a heating means, and a large number of three or four color dots are transferred to the transfer material by extremely short heating.
A full-color image of the document is reproduced using the multicolored 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
ことから非常に鮮明であり、且つ透明性に優れている為
、得られる画像は中間色の再現性や階調性に優れ、従来
のオフセット印刷やグラビア印刷による画像と同様であ
り、且つフルカラー写真画像に匹敵する高品質の画像が
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.
上記方法で画像形成が可能な被転写材は、染料染着性の
あるプラスチックシート或いは染料受容層を予め設けで
ある紙等に限定され、一般の普通紙等には直接画像が形

可能であるが、これは−船釣にはコスト高であり、例え

既製の被転写材には応用困難である。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. There's a problem. 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ようとする場合、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
容層転写シートか知られている（例えば、特開昭６２−
２６４９９４号公報参照）。As a way to solve these problems, when trying to form an image on a ready-made transfer material such as plain paper, a receptor layer transfer sheet is used as a method to easily form a dye receptor layer only in the necessary areas. is known (for example, JP-A-62-
(See Publication No. 264994).
更に操作を簡便にする方法として、長尺基材フィルムの
面にイエロー、シアン、マゼンタ及び必要に応じてブラ

ラー画像を形成する複合熱転写シートも提案されている
。Furthermore, as a method to simplify the operation, yellow, cyan, magenta, and, if necessary, black dye layers are sequentially formed on the surface of a long base film, and a transfer receiving layer is further formed on the same base film surface. A composite thermal transfer sheet has also been proposed in which a receiving layer is first transferred to a transfer material, and then dyes of various colors are transferred to the receiving layer to form a full-color image.
しかしながら、上記複合熱転写シートを使用する場合、
染料層が基材フィルムに強固に接着していることが要求
され（接着が弱いと転写時に染料層が転写する）、一方
、受容層は基材フィルムに適当な接着力で接着している
ことが要求される（接着が弱いと剥離は容易であるが、
箔切れが不良となり、一方、接着が強すぎると転写不良

した。The receiving layer surface of the composite thermal transfer sheet and plain paper are superimposed, and a thermal head is used to set the output IW/dot and pulse width to 0. ．． The receiving layer was transferred over the entire surface under the conditions of 3 to 0.45 m5ec and a dot density of 3 dots/mm, and then a yellow signal obtained by color separation of the original was printed on the surface of the receiving layer. , yellow dye layers were stacked to form a yellow image. Furthermore, a magenta dye was similarly transferred to the image area obtained above using a magenta signal, and a cyan dye was further transferred using a similar cyan signal to form a full-color image.
