本発明は感熱転写記録材に係わり、さらに詳しくはその
基材の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a thermal transfer recording material, and more particularly to improvement of its base material.

９１９号公報）。Conventional thermal transfer recording materials are produced by providing a heat-melting or heat-sublimating ink layer 3 on one side of a base material 2 made of a resin film such as a polyester film, as shown in FIG. (For example, JP-A-55-3
Publication No. 919).

いう態様で使用される。As shown in FIG. 6(a), it is used on the side of the base material 2 of the thermal transfer recording material 1 on which the ink layer 3 is not formed (hereinafter referred to as the back surface of the base material 2). The thermal head 4 is pressed against it, heated by electricity, and the ink l1i
3 is partially melted or sublimated, and the melted or sublimated ink is transferred onto the transfer target 11E5 in contact with the ink.

たりする。その結果、印字が不鮮明になったり、あるい
は印字エネルギーが無駄に消費されることとなった。By the way, when the thermal head 4 is pressed against the back surface of the base material 2 and heated with electricity as described above, the physical properties of the polyester film used as the base material are isotropic and have no directionality. Therefore, the heat from the thermal head 4 is uniformly diffused in all directions on the back surface of the base material 2, and the temperature curve of the ink layer 3 becomes a gentle curve as shown in FIG. 6(b). Although some portions are almost certainly transferred, both end portions may or may not be transferred depending on the surface condition of the transfer paper 5, the thickness of the ink layer 3, and other conditions. As a result, the print becomes unclear or printing energy is wasted.
この発明は、上記従来製品が持っていた印字の不鮮明さ

記録材を提供することを目的とする。The purpose of this invention is to solve the problems of the above-mentioned conventional products such as unclear printing and wasted printing energy, and to provide a thermal transfer recording material that can print clearly with less energy. .
本発明は、基材中に針状の強磁性体微粉末を混在させ、

By orienting the long axis of the acicular ferromagnetic fine powder in the thickness direction of the base material, the thermal conductivity in the thickness direction of the base material is increased, thereby achieving the above object.

少ないエネルギーで行えるようになる。That is, by mixing needle-shaped ferromagnetic fine powder in the base material,
If the long sleeve of the acicular ferromagnetic fine powder is oriented in the thickness direction of the base material, the thermal conductivity of the ferromagnetic fine powder is much higher than that of the resin part, so the thermal conductivity in the thickness direction of the base material is increased. is high due to the ferromagnetic fine powder, and is higher than the thermal conductivity in other directions, that is, the width direction and length direction of the base material.Therefore, in thermal transfer recording materials using this base material, the ink layer heating can be done more selectively and efficiently than conventional methods, and as a result, sharp and clear printing can be done with less energy.

間を通すことによって作製される。The base material used in the present invention, in which the long axis of acicular ferromagnetic fine powder is oriented in the thickness direction, can be obtained by, for example, mixing resin and acicular ferromagnetic fine powder, molding the mixture into a film, and using the resin. It is produced by passing the component between the north and south poles of an orientation magnet while the component has internal fluidity or after solidification and is given fluidity by heating a second time.

For example, it includes all shapes that are not spherical, such as cylindrical or spindle shapes, and whose lengths in the axial direction are not equal, for example, the length of the long sleeve is about three times or more the length of the short axis.

When placed between the poles, the long sleeve direction is easily magnetized, and the long axis direction is directed toward the rod direction of the magnet.Therefore, it is mixed with resin and formed into a film, and then When passed between the Ni and S poles of the orientation magnet in a state where the resin component has internal fluidity, the long axis direction becomes oriented in the thickness direction of the base material, and heat conduction in the thickness direction is improved. A base material with improved properties can be obtained.

った。In other words, this! In the thermal transfer recording material 1, the heat conductivity of the base material 2 in the thickness direction is high, so the heat from the thermal head 4 is efficiently transmitted to the ink N3, and the heat conductivity of the base material 2 in the width direction and length direction is high. is about the same as the conventional one and not particularly high, so there is less heat dispersion in the width and length directions, so the temperature of the ink layer almost corresponds to that of the thermal head, as shown in Figure 2 (b). As a result, the uncertain area of printing becomes narrower and clearer printing becomes possible. Furthermore, since the thermal conductivity to the ink layer 3 is good, even if the applied energy is smaller than that of the conventional method, a transfer area comparable to that of the conventional method can be obtained as shown in Table 1 below.

感熱転写記録材。(1) A heat-melting ink layer or a heat-sublimating ink layer is provided on one surface of the base material, a thermal head is pressed against the other surface, and the ink layer is melted or sublimated by heating with electricity. In thermal transfer recording materials that are transferred onto transfer paper, needle-shaped ferromagnetic fine powder is mixed in the base material, and the long axis of the ferromagnetic fine powder is oriented in the thickness direction of the base material. A thermal transfer recording material characterized by increased thermal conductivity in the thickness direction.
