ものより低くなることを経験した。[Industrial Field of Application] The present invention relates to improvement of thermosensitive coloring paper for recording characters, figures, and other images by thermosensitive coloring. [Prior Art] The appearance of images by thermal color development is used in a wide range of fields including facsimile. It has been pointed out that one of the drawbacks of thermosensitive recording is that it has poor storage stability. Problems with shelf life can be divided into fading due to heat and light, and low abrasion resistance.The former is being improved with improvements in heat-sensitive coloring agents and advances in fixing technology, but the latter is due to discoloration caused by heat and light. There is no other choice but to take measures such as installing a protective coating. The inventor has previously succeeded in greatly increasing the abrasion resistance by laminating a thin polyester (typically polyethylene terephthalate) film on the surface of heat-sensitive coloring paper, and has already proposed this. However, when implementing the invention, we experienced that when high-speed recording was attempted, the color density became lower than what could be expected from the original thermal recording paper.

以下、実施例１と同様にして感熱発色紙をつくった。Problem to be Solved by the Invention 1 The object of the present invention is to improve the above-mentioned points, and to provide a heat-sensitive recording medium that reduces the decrease in color density to a level that does not substantially pose a problem while ensuring abrasion resistance due to the surface protective coating. The goal is to provide paper. [Means for Solving the Problems] As shown in FIG. 1, the thermosensitive coloring paper of the present invention is made of plastic having high heat resistance and wear resistance, preferably PET
(polyethylene terephthalate) film (11) is coated with thermosensitive color ink (1) via a primer (12)
3) and dry laminating adhesive (1) on top of it.
4) is a heat-sensitive coloring paper (1) made by laminating paper as a base material, preferably high-quality paper (15). It is best for plastic films, such as PET, to be as thin as possible, and a film with a thickness of several micrometers should be selected. As the primer, one that is commonly used when applying various paints onto PET film may be used. The amount of application should also be as small as possible to ensure its effectiveness. It goes without saying that the heat-sensitive coloring agent can be arbitrarily selected from those commonly used in general recording paper. Although any adhesive for dry lamination can be used, a two-component curing type urethane adhesive is preferred. [Function] The PET film-protected heat-sensitive coloring paper proposed earlier is the second
As shown in the figure, heat-sensitive coloring ink (13) is applied to high-quality paper (15), which is the base material, and a PET film (11) is laminated thereon via a dry laminating adhesive (14). This is thermosensitive coloring paper (2). This heat-sensitive coloring paper has a relatively thick layer of dry lamination adhesive in addition to the PET film, and the heat from the thermal head is transmitted through these, so the heat is absorbed midway through and the heat-sensitive coloring agent has sufficient energy. was not added, resulting in insufficient color development. In the present invention, only a thin primer layer is placed between the PET film that protects the surface and the heat-sensitive coloring agent, so the thermal energy from the thermal head is less likely to be absorbed midway through, and a high proportion of the heat energy is applied to the heat-sensitive coloring agent. to see sufficient color development. Therefore, high-speed thermal recording is possible. [Example 1] 3.5μ thick PET film “Lumirror” (Toshi ■)

Next, a commercially available high-quality paper (DPC paper) was drawn on a hot plate, the temperature was kept at 70°C, and a urethane resin-based dry laminating adhesive "Takenate A-753J (Shikinichi Yakuhin Kogyo ■)" was applied to Myabar #8. (dry coating amount: 2.0 g/butt). The side of the above PET film coated with the heat-sensitive coloring ink was placed on the adhesive side of the high-quality paper, and the sheets were pressed together using a roller to prevent air from entering between them. [Example 2] PET film-covered thermosensitive coloring paper was produced in the same manner as in Example 1, except that "Dythermo DI (low temperature coloring type)" having the following composition was used as the thermosensitive coloring ink.
