本発明は、熱による物質の状態変化を利用した熱転写記

熱転写記録インクノートに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a thermal transfer recording ink sheet that utilizes a change in the state of a substance due to heat, and particularly to a thermal transfer recording ink notebook using a sublimation dye as a recording medium.

た。The conventional thermal transfer recording method generally uses the mechanism shown in FIG. The conventional ink sheet 14 used in this method has a heat-resistant protective layer 2, as shown in FIG. The ink layer 6 was applied to the upper surface of the base film 1 which was provided on the lower surface. By the way, since the polyester film used as the base film 1 lacks adhesiveness due to the number of bars, the adhesive force between the binder resin forming the ink layer 6 and the base film becomes weak, and the ink layer 6 is completely transferred to the recording paper 8 during recording. There is a problem in that so-called blocking is likely to occur. In addition, in a taping test in which adhesive tape was stretched over the 7 layers and the ink layer peeled off when the adhesive tape was removed, there was also a problem in that the ink layer 6 easily peeled off from the base film 1. .

ンクシートが得られる。As shown in FIG. 5, an article that solves these problems is such that an adhesive layer 12 containing fine particles 13 of alumina, silica, etc. is formed on the upper surface of the base film 1, and then an adhesive layer 12 is formed on the top surface of the base film 1. There is one in which an ink layer 6 is provided. According to this configuration, since the surface of the adhesive layer 12 is made uneven by the fine particles, the ink layer 6 is easily adhered, preventing blocking and providing an ink sheet that does not peel off even in a taping test.
発明が解決しようとする問題点
しかしながら、このような接着層１２を設けたインクシ

防ぐため塗布装置が複雑になってしまうという問題点を
生じている。Problems to be Solved by the Invention However, as shown in FIG. 6, the ink sheet 15 provided with such an adhesive layer 12 has a lower recording density than the ink sheet 14 without the adhesive layer 12 under the same conditions. Approximately 5
Not only does it decrease by ~10%, but also unevenness occurs in the recorded image. Further, there is a problem in that the coating device becomes complicated in order to prevent fine particles from settling during the adhesive layer coating process.
前記記録濃度が低下する理由は、アルミナ、シリカ等の

エネルギーが減少するためであり、また、記録画像のム
ラが発生するのは、微粒子が凝集し易く、画像に影響を
与えない程度に分散し、均一に塗布することが難しいた
めである。The reason why the recorded density decreases is that thermal energy is absorbed by fine particles such as alumina and silica, and the thermal energy transmitted to the ink layer decreases.Also, unevenness in recorded images occurs because fine particles This is because they tend to aggregate and are difficult to disperse and apply uniformly to an extent that does not affect the image.

クシートを提供することを目的とする。The present invention eliminates the peeling of the ink layer due to blocking and taping tests that occur during recording, and also eliminates the 0 degree drop and unevenness of recorded images that occur due to the mixing of fine particles, and enables thermal transfer recording that enables high-quality recording. The purpose is to provide ink sheets.

とする。Means for Solving the Problems In order to solve the above problems, the thermal transfer recording ink sheet of the present invention uses a polyester film as a base film, and an adhesive layer made of a di-copolymerized polyester resin is interposed on the base film. It is characterized in that an ink layer is provided.

ク層形成液との混合層が形成されるためインク層と接着
層との接着力も向上する。By using a copolymerized polyester resin as the functional adhesive layer, the adhesive strength to the base film made of polyester film is improved. In addition, in the ink layer coating process, the surface of the adhesive layer is dissolved and roughened by a solvent such as monochlorobenzene that dissolves the dye and binder, and the copolyester resin of the adhesive layer and the ink layer forming liquid are mixed. Since a layer is formed, the adhesive strength between the ink layer and the adhesive layer is also improved.
その結果、全体としてベースフィルムに対してインク層
の接着力が大きく向上される。また従来のように微粒を
使用していないので、均一な接着層を容易に形成可能と
なる。As a result, the overall adhesion of the ink layer to the base film is greatly improved. Furthermore, since fine particles are not used as in the conventional method, a uniform adhesive layer can be easily formed.

The thermal transfer recording ink sheet consists of a base film 1 with a heat-resistant protective layer 2 provided on the lower surface, an adhesive layer 3 provided on the upper surface of the base film 1, and an ink layer 6 provided on the adhesive layer 3. .

A sample prepared at 190° C. and a sample heated at 190° C. were each coated onto a base film 1 made of a polyester film provided with a heat-resistant protective layer 2 to a thickness of about 02 to 043 μm. Thereafter, an ink layer forming solution 4 prepared by dissolving a dye and a binder in a solvent such as ethyl acetate, methyl ethyl ketone, or monochlorobenzene was applied as shown in FIG. 4(a).

A mixed layer 5 of the dissolved copolymerized polyester resin and the ink layer forming solution 4 is formed. Then, by heating and drying, the adhesive layer 3 is
The ink sheet 16 is completed by providing the cured mixed layer 9 and the ink layer 6 thereon.

ら扛た。When the resulting ink sheets were subjected to a CheePig test, it was confirmed that both ink sheets using copolymerized polyester resins with a softening point of 150°C and a softening point of 190°C exhibited high adhesive strength. Further, when both ink sheets were used for recording with the recording load shown in FIG. 2, both ran without blocking and a uniform image was obtained. Regarding the recording density, the softening point is 15
It is possible to obtain a somewhat higher degree of elasticity with a softening point of 190°C than with I/R-7 using a copolymerized polyester resin at 0°C, and the average value of these is as shown in Figure 2. Almost the same recording density as that of the sheet 14 without the sheet was obtained.

のない高記録濃度の画像を得ることができる。As described in detail, the thermal transfer recording sheet of the present invention can improve both the adhesive strength between the base film and the adhesive layer, and between the adhesive layer and the ink layer. This makes it possible to firmly establish an ink layer on the base film without mixing fine particles such as alumina or phosphoric acid into the adhesive layer as in the past, making it possible to prevent the ink layer from peeling off during recording. It is possible to obtain even, high-density images without printing.
