な熱転写シートに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a thermal transfer sheet, and more particularly to a novel thermal transfer sheet having an excellent heat-resistant slip layer (back layer) made of a specific material.

トが使用されている。(Prior art and its problems) Conventionally, when printing output prints from computers or word processors using a thermal transfer method, a thermal transfer sheet with a heat-melting ink layer provided on one side of a base film has been used. .
この従来の熱転写シートは、基材フィルムとして厚さl

Using paper such as capacitor paper or paraffin paper with a thickness of 0 to 20 μm, or a plastic film such as polyester or cellophane with a thickness of 3 to 20 μm, a layer of heat-melting ink made by mixing coloring agents such as pigments and dyes with wax is applied. It is manufactured by coating.

たりする等の問題が発生する。In addition, when using a heat-resistant material such as a plastic film as the base film, the thermal head may become sticky during printing, impairing the peeling and slipping properties of the thermal head, or causing the base film to become sticky. Problems such as tearing may occur.
この様な問題点を解決する方法としては、背面層に耐熱
性の高い無機粒子や架橋樹脂粒子を包含させる方法が提
案されている。この様な耐熱性粒子を多量に添加すれば
する程、背面層の耐熱性は向上するが、添加量が大とな
るに従って、背面層の背面層強度が低下するという問題
がある。As a method for solving these problems, a method has been proposed in which the back layer contains highly heat-resistant inorganic particles or crosslinked resin particles. The more such heat-resistant particles are added, the more the heat resistance of the back layer improves, but there is a problem in that the greater the amount added, the lower the strength of the back layer.
特に、背面層は熱転写時の熱感度を考慮すると薄い程好
ましく、最近では0.5μm以下の厚みの背面層が要望

多量の耐熱粒子を背面層に包含させることが出来るが、
この場合には十分な耐熱性が得られない。In particular, the thinner the back layer is, the better, considering the thermal sensitivity during thermal transfer.Recently, there has been a demand for a back layer with a thickness of 0.5 μm or less. It is necessary to add large particles, and if a large amount of heat-resistant particles with a large particle size are added, there is a problem that the strength of the back layer decreases significantly, and it is not possible to form a thin back layer with sufficient heat resistance. There wasn't. Of course, if heat-resistant particles are used that are significantly smaller than the thickness of the back layer, a relatively large amount of heat-resistant particles can be included in the back layer.
In this case, sufficient heat resistance cannot be obtained.
従って、本発明の目的は以上の如き従来技術の欠点を解
決し、優れた耐熱性を有する背面層を設けた熱転写シー

For example, if the thickness of the back layer is 0.5 μm, If the grain size is less than half of the thickness, the effect of improving heat resistance will be small;
If it is larger than the film thickness, it is difficult to form a back layer with a smooth surface and the thermal head is abraded, which is not preferable.

。Thermal transfer images generally have glossy and beautiful prints, but the documents may become difficult to read, so matte prints are sometimes desirable. In such a case, for example, as proposed by the applicant (Japanese Patent Application No. 58-208306), an inorganic pigment such as silica, calcium carbonate, etc. is dispersed in a suitable solvent on a base film. It is preferable to form a thermal transfer sheet by coating a matte layer and then coating a heat-melting ink layer. Alternatively, the base film itself may be matted and used (the technique of Japanese Patent Application No. 58-208307, also proposed by the applicant).
