熱、転写層と接着性のよい材料にする必要があった。Problems to be Solved by the Invention In the conventional transfer-type thermal recording method, the thermal transfer layer is heated with a chemical to lower its viscosity, resulting in a problem in contact with the image-receiving paper (peeling and releasability from the body). Therefore, there was a problem that the strength (friction resistance) of the recorded image was insufficient due to the low heat resistance of the heat transfer layer. (1 degree) and (new) materials with high strength are used, but in that case the recording sensitivity is lower than in the past, and it is also necessary to use a material that has good adhesion to the heat and transfer layer for the surface of the image receiving paper.

Recording is performed by selectively transferring the material layer to image-receiving paper.

エネルギーでよい。Effects of the present invention For example, the adhesive material on the adhesive sheet is selectively transferred to the surface of the coloring material layer of the recording sheet by overlapping a recording sheet and an adhesive sheet and heating them from the adhesive sheet side with a thermal head. By forming an image, the adhesive force of the main surface of the coloring material layer is controlled (increased), and then the coloring material layer is pressed against the surface of the receiving paper, and by heating it, the adhesiveness of the part (the part of the adhesive material image) is reduced. ) is transferred to the surface of the image-receiving paper to form an image. Therefore, the recording energy required to form the adhesive layer 4j/I can be lowered by appropriately lowering the heat resistance of the adhesive layer. The energy required to transfer image 4 from the recording sheet to the surface of the receiver paper by compression and heating is determined by the softening point of the colorant layer material, etc. Therefore, less heat energy is required compared to selective heating using thermal or thermal heating.

できる。In addition, when transferring to image-receiving paper, the adhesive force formed in advance on the surface of the color material layer and the decrease in viscosity of the color layer due to heating,
Since the transfer is performed by pressing or pressing against the image receiving paper, it is possible to use a coloring layer material with comparatively high shear strength, and
The adhesive can be transferred to any receiver paper material that produces tack.

When the recording sheet +-10 is sandwiched between the heating roller 3 heated to C and the pressure roller 4, and the heating roller 4 heats the entire substrate side of the recording sheet +-10, the coloring material 1 is heated at the contact surface of the coloring material layer 9 with the recording sheet substrate 8. The viscosity of the dead material decreases, the adhesive force with the recording sheet substrate 8 decreases, and the surface of the adhesive image 12 on the surface of the coloring material layer 9 contacts and presses the surface of the image receiving paper 11. Sticky. Therefore, when the recording sheet].10 and the image receiving paper 11 are separated, the coloring material layer 9 is transferred to the image receiving paper 11 side in the area of the adhesive J+,) image 12, and a recorded image 13 is formed on the surface of the image receiving paper 11. In the case of color recording, for example, after performing the above operations on the cyan coloring material layer 9, the same operations are repeated on the yellow-magenta coloring material layer, so that a yellow-magenta recorded image is transferred to the receiver paper 11. The full color image is recorded over the cyan image.

に比へて熱効率が高くなる。The coloring material layer used in this example uses a material with high elongation at break ((temporal elongation) and strength at break in order to improve the abrasion resistance of each image. Therefore, the coloring material layer If the adhesive strength between the paper and the image receiving paper is not high enough, it will be difficult to cut inside the coloring material layer and peeling the coloring material layer from the sheet base surface. In order to transfer only the material layer by heating the thermal head to reduce its viscosity, it was necessary to form a material with strong adhesion to the coloring material layer on the surface of the image-receiving paper in advance.Coated image-receiving paper was prototyped for comparison. When the recording sheet 10 and the recording sheet 10 are stacked and heated and transferred by a thermal head from the recording sheet 10 side, the recording density of the thermal head is 4 doys.
)/mm linear type, the applied power per heating resistance element 1 do y b is 0.4 W, main scanning recording density 1ei, 7 ms
/line, jΔ11 scanning recording density 4 doors t/[n
rrh The recording pulse width was 4 ms, and the recording thermal energy was approximately 2.6 J/Cm2. On the other hand, when polypropylene synthetic paper without a coating layer is used, as in the 3 cases of low image reception and non-execution, the recording heat energy of 3 J/Cm2 does not allow the coloring material to be absorbed due to the lack of adhesive properties on the surface of the image receiving paper. Transcription was not possible. According to the present invention, the adhesive force can be made sufficiently strong by the adhesive layer, so that the surface material of the image receiving paper is
+Ajm can be freely selected from among the materials that produce adhesive strength. In addition, the adhesive material in this example has lower heat resistance (and is thinner) than the material for the coloring material layer, so only a small amount of energy is required for transfer recording with a thermal head. When transferring the image to a surface, the entire surface of the image is subjected to heating and pressure, so the thermal efficiency is higher than when selectively heating with a thermal head or the like.

る。Another method for controlling the tackiness of the surface of the coloring material layer is to drop a solvent that dissolves the hue layer material onto the surface of the coloring material layer depending on the image signal, spread it on the surface, or apply it to the surface of the coloring material layer. Is it possible to form an image on the adhesive layer by slightly dissolving and dissolving the adhesive in the color material layer? It is difficult to improve the resolution when forming a 11&1 shape, and the resolution becomes even lower because the solvent droplets expand when pressed against the image receiving paper. Therefore, it is difficult to record high-resolution characters and images.

もわずかでよい。In this example, as a method of controlling the adhesion of the main surface of the color material layer, the adhesive layer was transferred to the surface of the color +/1 layer with low adhesion, but conversely, a material with high adhesion was used. The color J
It is also possible to control the adhesive force by transferring a non-adhesive 1 liter type layer to the surface of layer A and lowering the adhesive force in that area. In this case, the part where #i type layer is not transferred is adhesive material + l! The LtI image is finally transferred and recorded on the image receiving paper. In this method, like the above-mentioned adhesive layer, the release layer may be thinner than the coloring material layer, so less energy is required for transferring the release layer, and image transfer is possible. Only a small amount of energy is required to heat the entire surface.

め、単光されない部分が粘着、材画偉を形成する。In this embodiment, the adhesive force was generated in the portion irradiated by the light source, but a structure may be adopted in which only the portion irradiated with light loses the adhesive force. In that case, for example, polymethyl methacrylate and triethylene glycol dimethacrylate are used as the color fc1 of the color layer 9, and pigments and dyes are dispersed as coloring materials. The parts that have been exposed to four UV rays are photocured and lose their adhesiveness, so the parts that have not been exposed to single rays of UV light become sticky and form a texture.
