本発明は、熱転写記録媒体に関し、特に記録時のシワや
巻取り不良などの発生が防止された熱転写記録媒体に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermal transfer recording medium, and more particularly to a thermal transfer recording medium that is free from wrinkles and poor winding during recording.
支持体上の常温では固体のインクをサーマルヘッドの熱

クシミリ、プリンターワープロ用として使用され、近年
高速化、高密度化が図られている。Thermal transfer recording method, in which ink that is solid at room temperature on a support is melted by the heat of a thermal head and transferred to plain paper, is highly reliable, easy to maintain, and easy to operate, and is easy to use.
It has the advantage of being easy to mold and reduce cost, and is used for facsimile machines and printers and word processors, and in recent years, efforts have been made to increase speed and density.
ところが、ファクシミリ用、プリンター用の一部の熱転

より使用済み記録媒体巻取り径の肥大化をもたらし、巻
取り不良が発生することがあった。However, some thermal transfer recording media for facsimiles and printers are wide and cannot absorb the distortion caused by shrinkage of the support and protective layer during recording, resulting in wrinkles and missing characters. It has become a cause of dirt and grime. Furthermore, even with narrow thermal transfer recording media for word processors, distortion may cause the winding diameter of the used recording medium to increase, resulting in poor winding.
なお、支持体裏面に耐熱性樹脂からなる保護層を設ける
ことが提案されている（特開昭６１−１７５０８９号、
同６３−４９４８５号各公報）が、これらの記録媒体を
使用しても、ステンキング防止や秘密漏洩防止としての

ることはできない。Incidentally, it has been proposed to provide a protective layer made of a heat-resistant resin on the back surface of the support (Japanese Patent Application Laid-open No. 175089/1989,
63-49485), even if these recording media are used, they are effective in preventing streaking and preventing leakage of secrets, but the effect on the recording medium fabric during recording is insufficient. Therefore, the occurrence of wrinkles due to distortion cannot be sufficiently prevented.
従って、本発明の目的は、記録時におけるシワや巻取り
不良の発生原因となる歪を生じない熱転写記録媒体を提
供することにある。Accordingly, an object of the present invention is to provide a thermal transfer recording medium that does not generate wrinkles or distortions that cause poor winding during recording.
本発明によれば、耐熱性支持体の上面に熱転写性インク

において、該保護層が耐熱性微粒子を２５〜９０９量Ｘ
含有するものであることを特徴とする熱転写記録媒体が
提供される。According to the present invention, in a thermal transfer recording medium comprising a heat-transferable ink layer on the upper surface of a heat-resistant support and a heat-resistant protective layer on the lower surface, the protective layer contains heat-resistant fine particles in an amount of 25 to 909
Provided is a thermal transfer recording medium comprising:
即ち、本発明の熱転写記録媒体は、耐熱性微粒子を２５

に設けたことにより、記録時に歪が発生せず、従ってシ
ワや巻取り不良が発生しないものとなる。That is, the thermal transfer recording medium of the present invention contains 25 heat-resistant fine particles.
By providing the heat-resistant protective layer containing ~90 volume 2 on the back surface of the heat-resistant support, distortion does not occur during recording, and therefore wrinkles and poor winding do not occur.
本発明においては、支持体裏面に耐熱性微粒子を２５〜
９０容量Ｉ含有する耐熱保護層が設けられる。In the present invention, heat-resistant fine particles are coated on the back surface of the support.
A heat-resistant protective layer containing 90 capacitance I is provided.
