及びその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to W! -Regarding a thermal transfer recording medium and its manufacturing method. In particular, the present invention relates to a thermal transfer recording medium with receiving paper used for computer-aided design (CAD), facsimile, image enlargement, etc., and a method for manufacturing the same.
従来の技術及び発明が解決しようとする課題ＣＡＤ、フ
ァクシミリ、画像拡大等に使用される受け紙付感熱転写
記録媒体においては、受け紙紙面がそのまま被転写物と

紙を貼り合せるためのラミネート法が極めて重要な意味
を有することとなり、従来のラミネート法をそのまま適
用することはできない。Problems to be Solved by Prior Art and Inventions In thermal transfer recording media with receiving paper used for CAD, facsimile, image enlargement, etc., due to the usage requirement that the receiving paper surface becomes the transferred object as it is, It is necessary that the paper surface itself has good writing properties, printing properties, handling properties, storage properties, etc. (paper texture). Therefore, the lamination method for bonding the heat-sensitive transfer sheet and the receiving paper has an extremely important meaning, and the conventional lamination method cannot be applied as is.
従来、ラミネート法にはウェットラミネート法、ホット
メルトラミネート法及びドライラミネート法がある。Conventionally, lamination methods include a wet lamination method, a hot melt lamination method, and a dry lamination method.
ウェットラミネート法はソルベントラミネート剤、水性

合せる方法である６ したがって、この方法は、塗布さ
れたラミネート剤層が残存する揮発性物質によっては、
その性質に経時変化を生じるという欠点がある。The wet lamination method is a method in which a solvent laminating agent or an aqueous laminating agent is applied and the materials are bonded together before the volatile substances evaporate.6 Therefore, depending on the volatile substances remaining in the applied laminating agent layer,
It has the disadvantage that its properties change over time.

また、感熱転写シート側にラミネート剤を塗布する場合

態のラミネート剤によって貼り合せを行う、この方法は
感熱転写インキ層及びラミネート剤層の融点を適当に選
択することにより可能ではあるが、技術的に種々な制約
を伴う場合が多い。The hot melt lamination method is a method in which the applied laminating agent is bonded before it solidifies, that is, while it has fluidity. At this time, if a laminating agent is applied to the paper side and bonded together, a coating amount of 2 g/12 or more is required, and the paper surface needs to be processed, which impairs the good texture of the paper.
In addition, when applying a laminating agent to the thermal transfer sheet side, apply the laminating agent in a state where the thermal transfer ink does not diffuse into other layers, that is, in a state where the thermal transfer ink layer is not dissolved. This method is possible by appropriately selecting the melting points of the heat-sensitive transfer ink layer and the laminating agent layer, but it is often accompanied by various technical restrictions. .
ドライラミネート法は塗布後のラミネート剤層の粘着性
によって貼り合せを行う方法である。この方法において
は、通常、常温で粘着性を有する固形物または硬化剤が
使用される。常温で粘着性を有する固形物を使用する場
合には、ラミネート剤が受け紙に転移するという問題点
があり、また、硬化剤を使用する場合には、硬化したラ
ミネート剤層によって感熱転写が不可能になる。The dry lamination method is a method in which bonding is performed using the adhesiveness of the laminating agent layer after application. In this method, a solid substance or a hardening agent that is sticky at room temperature is usually used. When using a solid substance that is sticky at room temperature, there is a problem that the laminating agent transfers to the receiving paper, and when using a hardening agent, the cured layer of laminating agent may prevent thermal transfer. It becomes possible.
また、上記従来のラミネート法では印字の鮮明性の点か
らはラミネート剤の塗布量として１〜２ｇ／ｍ２以下が
好ましかったが、この塗布量ではサーマルヘッドによる
感熱転写シートのつき現象（受け紙から感熱転写シート
が剥離する現象）が生じるという問題点があった。更に
、転写後に転写シートを剥離した受け紙の表面がベタつ
くという問題点もあった。In addition, in the conventional laminating method described above, from the viewpoint of print clarity, the coating amount of the laminating agent is preferably 1 to 2 g/m2 or less, but this coating amount causes the phenomenon of sticking of the thermal transfer sheet by the thermal head (reception). There was a problem in that the thermal transfer sheet peeled off from the paper. Furthermore, there was also the problem that the surface of the receiving paper from which the transfer sheet was peeled off after the transfer was sticky.
