【発明の詳細な説明】
本発明は種々の熱記録装置に好適に使用されう
る新規な感熱記録体に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel thermal recording medium that can be suitably used in various thermal recording devices.
近時、感熱プリンター、感熱フアクシミリなど
の熱記録装置における複写方法として、つぎのよ
うな方法が提案されている。 Recently, the following methods have been proposed as copying methods for thermal recording devices such as thermal printers and thermal facsimiles.
すなわち、２枚の感熱紙を重ね合わせてサーマ
ルヘツドから発生するジユール熱によつて双方の
感熱紙の発色面に同一パターンの印字像を形成せ
しめるか、または１枚の感熱紙の裏面に熱溶融性
インキ層を設け、該インキ層に上質紙を配置して
感熱紙の発色と共に、同一パターンの印字像を上
質紙上に熱転写せしめるなどの方法である。 In other words, two sheets of thermal paper are placed one on top of the other and the same pattern of printed images is formed on the colored surfaces of both sheets of thermal paper using the heat generated from the thermal head, or a printed image of the same pattern is formed on the back side of one sheet of thermal paper. In this method, a thermosensitive ink layer is provided, a high-quality paper is placed on the ink layer, and a printed image of the same pattern is thermally transferred onto the high-quality paper while the thermal paper develops color.
しかしながら、まず２枚の感熱紙を重ね合わせ
たものにあつては、加熱発色に多量のジユール熱
を必要とし、そのため鮮明な印字像をうるために
は複写スピードを１秒あたり約30文字程度と遅く
しなければならず、また感熱紙自体も高価である
のみならず、堅牢性および改ざん性にも劣り、さ
らに鮮明な印字像をうるためには２枚の感熱紙を
充分に密着させる必要があり、取り扱いが煩雑で
あるなどの欠点がある。 However, in the case of two sheets of thermal paper stacked one on top of the other, a large amount of Joule heat is required for heating and color development, and therefore, in order to obtain a clear printed image, the copying speed must be approximately 30 characters per second. Furthermore, the thermal paper itself is not only expensive, but also poor in robustness and tamper resistance, and in order to obtain a clear printed image, it is necessary to place two sheets of thermal paper in close contact with each other. However, there are disadvantages such as complicated handling.
一方、感熱紙の裏面に熱溶融性インキ層を設け
たものにあつては、前述のごとき２枚の感熱紙を
用いるばあいにおける複写スピードが遅いという
欠点は解消せられるものの、このものもまた感熱
紙を用いるために、感熱紙自体に起因する欠点で
ある堅牢性、改ざん性などにおいて充分に満足し
うるものではなく、また価格も高くなるなどの欠
点を有している。 On the other hand, thermal paper in which a heat-melting ink layer is provided on the back side solves the disadvantage of slow copying speed when using two sheets of thermal paper as described above, but it also Since thermal paper is used, it is not fully satisfactory in terms of robustness, tamperability, etc., which are disadvantages of thermal paper itself, and it also has disadvantages such as being expensive.

At least one of the transfer sheets 3 and 31 (for example, the sheet 3 in contact with the thermal head 6 in FIG. 2) has an outer surface with a base smoothness of 5,000 to 70,000.
It is made of transparent or translucent paper whose inner surface in contact with the ink layers 2 and 21 has a base smoothness of 100 to 5000 seconds (JIS P8119).

な効果を奏しうる。 However, the heat-sensitive recording material of the present invention is one in which a layer of heat-melting ink is transferred onto a transfer sheet such as plain paper in accordance with a printed pattern, without using heat-sensitive paper as in conventional copying methods. Compared to thermal recording media using conventional thermal paper, it is extremely durable and tamper-resistant, can be manufactured at low cost, and has significantly improved printing speed and handling. This can have a remarkable effect.

For example, papers such as plain paper, synthetic paper, and laminated paper, and resin films such as polyethylene, polystyrene, and polypropylene are preferably used. Further, the thickness of the base material 1 is preferably approximately 10 to 25 μm in order to obtain good thermal conductivity.

けで、容易に前記印字像がえられるものである。 Examples of powdered thermally conductive substances include black pigments such as acetylene black, lamp black, graphite, aniline black, and Kettien Black (trade name), which have a thermal conductivity of 6.0×10 -4 to 25.0×.
10 −4 cal/sec·cm·°C, and materials with good thermal conductivity such as metal powders such as aluminum, copper, tin, or zinc are preferably used. Such a thermally conductive substance promotes the heat conduction effect of melting, softening, or sublimating the heat-melting ink layer applied to the back surface of the base material 1, and the ink is melting, softening, or sublimating. This can shorten the sublimation time. This thermally conductive substance is preferably mixed in a proportion of 2 to 30 parts with respect to 100 parts (by weight, the same applies hereinafter) of the total amount of the ink layer, and the heat-melting ink layers 2 and 21 formed within this range are The transferability is excellent, and the transferred printed image becomes very clear, and the printed image can be easily obtained by simply bringing the transfer sheets 3 and 31 into light contact.

In order to improve the pressure sensitivity of the resulting ink layer, it is preferable to use solid waxes such as wood wax, beeswax, ceresin wax, spermaceti wax, etc., but if necessary, low molecular weight waxes are used. Materials that can be easily melted by heat, such as polyethylene, oxidized wax, and ester wax, may be used in combination.

に使用可能である。 As the softener, materials that can be easily melted by heat, such as polyvinyl acetate, polystyrene, styrene-butadiene copolymers, cellulose esters, cellulose ethers, and acrylic resins, or lubricating oils are preferably used. Ru. As the colorant, various dyes or pigments that have been conventionally widely used in the field of copying paper can be used without any particular restrictions.

The blending ratio is preferably 5 to 35 parts, or 2 to 25 parts. In this case, the melt transferability of the formed heat-melting ink layers 2, 21 is very good.

てもその効果は向上することがない。 In the transfer sheets 3 and 31 of the present invention, at least one of the sheets has an excellent outer surface smoothness (Beck smoothness of 5000 to 70000 seconds), and an inner surface in contact with the heat-melting ink layer 2 or 21 is smooth. The density is low (100 to 5000 seconds in Becks smoothness),
Preferably it is a transparent or translucent paper of 0.9-1.4. The outer surface of such transparent or translucent paper is in direct contact with the thermal head 6, as shown in FIG. 2, and receives the thermal heat from the thermal head 6 during printing. However, if the smoothness of the outer surface of the transfer sheet 3 in contact with the thermal head 6 is less than the above range, the smoothness is poor and the sheet 3 and the thermal head 6 are
This results in poor adhesion, resulting in uneven transfer density. Further, even if the smoothness is increased beyond the above range, the effect will not be improved. On the other hand, when the smoothness of the inner surface of the transfer sheet 3 is greater than the above range, the heat-melting ink layer 3 transferred onto the sheet 3 is not sufficiently fixed due to the excellent smoothness. As a result, the resulting printed image becomes inferior in clarity, robustness, and tamperability. Further, even if the smoothness is made smaller than the above range, the effect will not be improved.

This is because the printed image 9 can be correctly read from the back side thereof.

応じて部分的に溶融する。 In the thermal recording medium 4, one transfer sheet 3 is in contact with the thermal head 6, and the other transfer sheet 31 is in contact with the platen 5. When pulses corresponding to the print pattern are applied from the terminals 7 and 8, the thermal head 6 generates joule heat from dots corresponding to the print pattern. The Joule heat is transmitted to the heat-fusible ink layer 2 via the transfer sheet 3, partially melting the ink layer 2 according to the printed pattern, and further passes through the base material 1 to the heat-fusible ink layer 21. The ink layer 21 is transmitted instantaneously, and the ink layer 21 is partially melted in accordance with the printed pattern, similarly to the heat-melting ink layer 2.
