持体である。However, printed images obtained from conventional thermal transfer recording media have a problem in that the surface gloss is high and difficult to read. Therefore, for example, thermal transfer recording media that remove the gloss of printed images by providing a matte layer containing a resin and a matte pigment between the support and the ink layer, and A thermal transfer recording medium has been proposed in which the gloss of the printed image is removed by providing an anchor layer that forms fine irregularities on the peeling surface of the ink layer. However, with these thermal transfer recording media, although the gloss of the printed image is removed, for example, if the power is turned off all day long,
When used in a high-temperature environment such as a facsimile machine that is in the N state and tends to accumulate heat, for example, in the thermal transfer recording medium shown in FIG. 2, the ink layer A containing a heat-melting substance is likely to peel off inside the ink layer. , since peeling at the interface C with the matte layer (or anchor layer) B, which is the intended peeling surface of the ink layer A, is prevented, as a result, the film thickness of the ink fiA transferred onto the transfer medium becomes thinner. Therefore, there is a problem that the print density decreases. In addition, in FIG. 2, D is a support body.

Furthermore, in order to improve the quality of printed images formed by thermal transfer recording media and obtain clear printed images, it is generally desirable that the media have fewer voids and high resolution. The present invention has been made based on the above circumstances. The purpose of the present invention is to be able to obtain printed images that do not decrease in density even in high-temperature environments, have low surface gloss, and are easy to read, have excellent confidentiality, and have less voids. The objective is to provide a thermal transfer recording medium with high resolution. [Means for Solving the Problems] In order to solve the above problems, as a result of extensive studies by the present inventor, a specific non-transfer layer containing a specific substance is provided between the support and the transfer layer. In a specific thermal transfer recording medium provided with a transfer layer, even in a high-temperature environment, the transfer layer peels off due to cohesive failure near the interface with the non-transfer layer, so the density decreases. The present invention was achieved by discovering that the printed image has low surface gloss and is easy to read, has excellent secrecy, has little voiding, and has high resolution. The structure of the invention of claim 1 includes a non-transfer layer containing a thermoplastic polymer and a coloring material between the support and a transfer layer containing a heat-fusible substance and a coloring material, and the non-transfer layer containing a thermoplastic polymer and a coloring material. The thermal transfer recording medium is characterized in that the thermoplastic polymer is a mixture of at least one member selected from the following group A and at least one member selected from the following group B.

One of the important points in the present invention is that at least one member selected from the above group A and at least one member selected from the above group B are provided between the support and the transfer layer described in detail below. The purpose is to provide a non-transfer layer containing a mixture of By providing this non-transfer layer, in the thermal transfer recording medium of the present invention, when the transfer layer described in detail below is peeled off from the support side, it is stable near the interface between the non-transfer layer and the transfer layer even in a high temperature environment. By realizing cohesive failure peeling, it is possible to form a clear printed image with high density and low surface gloss, making it easy to read. More specifically, stable cohesive failure peeling is achieved near the interface between the non-transfer layer and the transfer layer even in a high-temperature environment, so the transfer layer transfers to the transfer medium at a predetermined thickness and there is no decrease in density. When the non-transfer layer forms fine irregularities on the peeled surface of the transfer layer, that is, on the surface of the printed image, it is possible to produce a printed image with low surface gloss.

の所謂白抜け部が生じるのを防止する作用を有する。In addition, the non-transfer layer remains on the support even after the transfer layer is transferred to the transfer medium, and since it contains a coloring material, it prevents the occurrence of the so-called white areas described above, and is suitable for the present invention. To improve the confidentiality of thermal transfer recording media. Such actions or functions of the non-transfer layer are mainly brought about by the thermoplastic polymer and the coloring material contained in the non-transfer layer. A thermoplastic polymer selected from the above Group A [hereinafter, this may be referred to as polymer (I). ] and a thermoplastic polymer selected from Group B [hereinafter, this may be referred to as polymer (II)]. ] The proportion of each of the polymer (I) and the polymer (II) in the mixture is such that the polymer (1) is usually 3 to 80% by weight, preferably 3 to 5% by weight

It is 80% by weight, preferably 20 to 60% by weight. If the proportion of the polymer (I) in the mixture is less than 3% by weight, the adhesive force between the non-transfer layer and the transfer layer may decrease, making it unsuitable for practical use. On the other hand, if the proportion of the polymer (II) in the mixture is less than 3% by weight, the adhesive force between the non-transfer layer and the support decreases, even after the transfer layer is transferred to the transfer medium. The non-transfer layer that should remain on the support may peel off from the support. In any case, if the respective proportions of the polymer (1) and the polymer (II) are out of the above range, the effects of the present invention may not be sufficiently exerted. The polymer (I) has a melt index (Ml

供することができる．The results are shown in the work table. The glossiness, resolution, voids, density reduction, and confidentiality of the printed image were evaluated as follows. Glossiness: Using a glossmeter, the glossiness of the printed image was measured under the condition that both the incident angle and the reflection angle were 50", and glossiness of 15 or less was rated as ○, and glossiness of 15 or more was graded as ×.Resolving power : Visually observed the fraying of the K line of the L dot, and marked ◎ if there was no fraying, ○ if some fraying was observed, and × if there was fraying. Voids: Visually observed. Density decrease: Temperature inside the machine 40° Printing was carried out under the conditions of C, and a density of 1.4 or less was marked as ×, and a density of 1.4 or more was marked as ○. Confidentiality: Visual tlI inspection was performed using reflected light for missing parts after printing, and even part of the marks were marked as missing. Those with no missing parts were marked as ×, and those with no missing parts were marked as ○. (Example 2) In the above Example 1, the following non-transfer layer set was used instead of the non-transfer layer set used in Example 1. The test was carried out in the same manner as in Example 1 above, except that the same method was used as in Example 1.

Average particle size: 0.3φ) ・・20% by weight (This page, the following margins) Table 1 (Evaluation) As is clear from Table 1, the thermal transfer recording medium of the present invention shows no decrease in density even in high-temperature environments. It has been confirmed that it is possible to form high-quality printed images with a high level of secrecy, high resolution, and few voids. [Effects of the Invention] According to the present invention, (1) Since the non-transfer waste between the support and the transfer layer contains a specific compound, it is always stable even in a high-temperature environment such as a line printer of a facsimile machine. The transfer layer peels off due to stable cohesive failure that occurs near the interface between the transfer layer and the non-transfer layer, so there is no loss of density, and the surface gloss of the print image is low, making the print image easy to read. (2) After the transfer layer is transferred onto the transfer medium, the non-transfer layer remaining on the support contains a coloring material, so that so-called white areas that are legible are generated. It is possible to provide a high-performance thermal transfer recording medium that has various advantages such as (3) high secrecy, high resolution, and little generation of voids.
