構造をもつものである。 In recent years, with the development of thermal heads, thermal recording methods have been adopted in printers and facsimile machines. This paper, called thermal recording paper, is usually used there. This thermosensitive recording paper generally has a structure in which a thermosensitive coloring layer is provided on a base paper, which is a dispersion mixture of two components that react and develop color when dissolved.
このため、記録後の改ざん性、保存性あるいは
耐溶剤性などに問題を生じる。また、塗工紙であ
るために、どうしても紙としての自然性に欠ける
といつた欠点も有している。 This causes problems in tamperability, storage stability, solvent resistance, etc. after recording. Furthermore, since it is a coated paper, it has the disadvantage that it lacks the naturalness of paper.

ある。 Thermal transfer recording is a solution to these problems. This involves preparing a thermal transfer recording sheet with a heat-melting ink layer on a support, overlaying it with plain paper, such as ordinary high-quality paper, and converting the thermal transfer recording sheet to plain paper by heating from a thermal head. Recording is performed by transferring ink.

る。 However, conventional thermal transfer recording sheets have been disadvantageous in terms of economy because they can be used for so-called one-time recording, that is, only once. Furthermore, in the case of one-time recording, handling of used thermal transfer recording sheets that are no longer needed after recording also becomes a problem.
本発明者らはこれらの欠点を解決することを目

ることが必要であることを見い出した。 With the aim of solving these drawbacks, the present inventors have conducted intensive research to obtain a thermal transfer recording sheet that can be used many times.As a result, in thermal transfer recording, first, heat is applied from a Marsal head, etc.
Once the ink layer is sandwiched in the middle, the support of the thermal transfer recording sheet and the transfer paper such as high-quality paper are joined together, and then this support and the transfer paper are peeled off. At this time, it is thought that the separation occurs at the weakest point, so the results may vary depending on the relative relationship between the adhesive force between the ink and the transfer paper, the breaking strength of the ink, and the adhesive force between the ink and the support. It has been found that in order to achieve this, it is necessary to achieve a state in which the ink strength is relatively small compared to the adhesive strength between the ink and the support or the ink and the transfer paper.
本発明は、このような観点から為されたもので

トが得られることとなつた。 The present invention has been made from this point of view, and includes a resin layer interposed between the ink layer and the support, and a low melting point resin contained in the ink layer to improve the relationship between the ink layer and the support. It has improved adhesive strength. This made it possible to realize the above-mentioned state, and it became possible to obtain a thermal transfer recording sheet that can be used many times.

おいて本発明の方が優れている。 Similar to the present invention, there is an invention described in Japanese Patent Application Laid-Open No. 54-68253 that aims to use a thermal transfer recording sheet multiple times. It is filled with heat-sensitive ink, and the ink oozes out little by little each time it is recorded, allowing it to be used many times. In this way, that invention imparts a special structure to the thermal ink layer, but the present invention has a thermal ink layer that is uniformly dispersed and mixed, so it has the advantage of being able to record evenly and uniformly. The present invention is better.
次に本発明による熱転写記録シートの構成材料
あるいは製造工程を説明する。 Next, the constituent materials and manufacturing process of the thermal transfer recording sheet according to the present invention will be explained.

キシ樹脂などは一般に良好な結果をもたらす。 First, the support should be thin in terms of recording properties, and paper such as 10 to 30 .mu.m condenser paper or glassine paper, or plastic film such as polyester or polyimide is used. A resin layer can be provided on the support by applying a suitable resin solution to the support using a wire bar or the like so that the coating amount becomes 1 to 3 μm in thickness after drying. The resin should be selected in consideration of the ink, and any resin may be used as long as it strengthens the adhesive force between the ink layer and the support, but polyvinyl butyral resin or epoxy resin generally yields good results. bring.
次いで、この樹脂層の上に予め調整しておいた
熱溶解性インクを溶解状態でワイヤーバーなどで
塗布することにより熱転写記録シートを得る。 Next, a thermal transfer recording sheet is obtained by applying a previously prepared heat-melting ink onto this resin layer in a molten state using a wire bar or the like.

As the softener, any softener may be used as long as it is liquid at room temperature, stable, uniformly mixed into the ink in fractions, and does not interfere with the adjustment of the ink.
Specific examples include oleic acid, castor oil, dioctyl phthalate, liquid paraffin, and mineral oil. Various commonly used inorganic pigments, organic pigments, or dyes can be used as the coloring material, but carbon black is preferred because of its color tone and weather resistance.

When recording was performed using NEFAX-3000 in the same manner as in Example 1, in the case of solid black recording, all the ink was transferred to the transfer paper in one recording.
It could not be used again. In addition, in the case of a normal original, all the ink in the recorded area was transferred to the transfer paper, and if the recording was repeated two or three times, only a hard-to-read record with white spots could be obtained.
