Abstract

PURPOSE:To enable to transfer images with high image quality without any effect of the surface of a transfer paper, by providing an ink layer comprising as a binder a hot-melt adhesive becoming adhesive to a transfer paper when being melted or softened by heating, on a releasing agent layer provided on a base film. CONSTITUTION:The releasing agent layer 2 is easily melted by heat, resulting in that the base film 3 and the ink layer 1 can be separated from each other. The layer 2 is formed from, for example, a wax or a low molecular weight polyethylene in a thickness of about 1-2mum. The ink layer 1 comprises a hot- melt adhesive as a binder, to which a pigment such as carbon black and/or a dye such as oil black is added. The hot-melt adhesive is, for example, an ethylene-acrylic resin or a polyester resin, and the thickness of the ink layer is about 2-10mum. When a thermal head partially generates heat according to a recording signal, the ink layer at that part is separated from the base film, and is directly transferred onto the transfer paper.

"Prior Art and its Problems" A conventional thermal transfer medium, as shown in FIG. A transparent ink layer 5a is provided. The recording operation of this thermosensitive recording medium is shown in Fig. 2(b).
Based on this, the base layer 6 includes a thermal hood 7.

Then, when the thermal head 7 is driven in accordance with the recording signal and that part generates heat, the heat-melting ink 5a in the corresponding part of the base layer 6 is melted and transferred onto the transfer paper 8. This transfer ink 5b causes the transferred paper 8 to
A transfer image is formed according to the recording signal, and recording on the transfer paper 8 using plain paper becomes possible.

However, since the conventional thermal transfer medium described above impregnates the surface of the transfer paper with thermally molten ink, it is easily affected by the surface of the transfer paper. When the temperature is less than 30 to 40 seconds, ink application becomes uneven, which causes image quality deterioration.

Therefore, by increasing the thickness of the ink so that more ink is transferred to one point, the ink will reliably cover the surface of the transfer paper, eliminating the problems of decreased recording density and blur due to poor ink transfer. However, on the other hand, blurring becomes larger and the size of one dot becomes larger, which deteriorates resolution and causes deterioration of image quality.

Therefore, when the thermal head partially generates heat in response to a recording signal, the ink layer in that part melts and softens, has adhesive strength, and adheres to the convex portion of the transfer paper. At this time, the release layer of the heat generating part by the thermal head is melted by heat, for example, to separate the ink layer from the base film. Therefore, the ink located in the concave portions of the transfer paper is separated from the base film together with the ink attached to the surrounding convex portions and transferred to the transfer paper side. That is, since the hot melt adhesive contained in the ink layer acts as a binding force between the inks, the ink located in the recesses of the transfer paper is transferred together with the ink attached to the convex portions of the transfer paper. Therefore, even if the surface of the transfer paper is uneven, the entire ink layer corresponding to the heat generating portion of the thermal head is transferred to the transfer paper, and good image quality without uneven printing can be obtained.

In this thermal transfer medium, when the thermal head is driven in accordance with a recording signal and generates heat in a portion, the ink layer 1 in that portion melts and softens, has adhesive strength, and adheres to the convex portion of the transfer paper. At this time, the peeling layer 2 of the heat generating part by the thermal head is melted by heat and separates the ink layer 1 from the base film 3. Therefore, the ink located in the concave portions of the transfer paper is separated from the base film 3 together with the ink attached to the surrounding protrusions due to the bonding force between the inks, and is transferred to the transfer paper side. Therefore, even if the surface of the transfer paper is uneven, ink can be evenly applied to the transfer paper and good image quality can be obtained.

"Effects of the Invention" As explained above, according to the present invention, a release layer is formed on a base film, and an ink layer using a hot melt adhesive as a binder is formed on this release layer. When the thermal head partially generates heat in response to a recording signal, the ink layer in that part is separated from the base film and transferred as is to the transfer paper. For this reason, even if a transfer paper with a Bekk smoothness of 30 to 40 seconds or less is used, for example, the ink is uniformly applied to the transfer paper and a clear image can be obtained without being affected by the unevenness of the surface. I can do it.
