関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a thermal transfer recording medium, and more particularly to a thermal transfer recording medium that can prevent the sticking phenomenon from occurring.
［従来技術］

、記録時に加熱された加熱ヘッドによってフィルム支持
体の一部が溶融して加熱ヘッドに融着することがある。[Prior Art] In a thermal transfer recording medium using a polymer film such as a polyethylene terephthalate film as a film support, a part of the film support is melted and fused to the heating head by the heating head heated during recording. There is.
この現象はスティッキング現象と称されており、記録品
質を著しく低下させ、ついにはフィルム支持体が加熱ヘ
ッドに焼き付いて感熱転写記録媒体の送りを不可能に至
らしめる。This phenomenon is called a sticking phenomenon, and it significantly deteriorates the recording quality and eventually causes the film support to become stuck to the heating head, making it impossible to feed the thermal transfer recording medium.

なけらばならず、加熱ヘッドの寿命を著しく損なってし
まう欠点が生じる。To prevent this sticking phenomenon, it is possible to use paper with excellent heat resistance such as condenser paper as the film support, but if such paper is used, heat conduction from the heating head is poor, so the heating head The applied force must be increased, which has the drawback of significantly shortening the life of the heating head.

欠点がみられた。On the other hand, as a technique for preventing the sticking phenomenon, there is a technique using a backing layer. For example, JP-A-55-746
Publication No. 7 proposes providing a heat-resistant protective film made of silicone resin or the like on the film support, but since the friction with the heating head is large, long-term I! Jl recording has the disadvantage that the heating head wears out. Furthermore, JP-A-57-129789 proposes providing a resin layer on a film support containing a surfactant or organic salt that is solid or semi-solid at room temperature; Since the resin layer absorbs moisture, a so-called sticky appearance occurs, resulting in a drawback that the thermal head becomes extremely dirty.
