Description
【発明の詳細な説明】
本発明は、インク層がはがれることなく均一な
印字品質を得ることのできるくり返し転写可能な
熱転写インクシートを得るための製造方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manufacturing method for obtaining a thermal transfer ink sheet capable of being repeatedly transferred and capable of obtaining uniform printing quality without peeling of the ink layer.
従来は中間層、インク層塗布後は自然乾燥ある
いはインク層表面を強風や熱風で強制乾燥してい
た。各層はトルエン・アセトン等の比較的蒸発速
度の速い有機溶剤を含んでいるので強風や熱風で
はインク層表面にひび割れや凹凸を生じやすく、
自然乾燥では溶剤が完全に蒸発するまでに時間が
かかる欠点がある。 Conventionally, after coating the intermediate layer or ink layer, the ink layer surface was dried naturally or the surface of the ink layer was forcedly dried with strong or hot air. Each layer contains organic solvents such as toluene and acetone that have a relatively fast evaporation rate, so strong or hot wind tends to cause cracks and unevenness on the surface of the ink layer.
Natural drying has the disadvantage that it takes time for the solvent to completely evaporate.
また従来法では中間層の接着効果を発現せしめ
るには約10μｍ以上の中間層厚さが必要であり、
加熱転写時の熱効率の低下を招いていた。 In addition, in the conventional method, the intermediate layer needs to have a thickness of approximately 10 μm or more in order to exhibit its adhesive effect.
This resulted in a decrease in thermal efficiency during thermal transfer.
本発明の目的は、この従来欠点を解決すること
にあり、これはインクシートを基材側から加熱す
ることによりインク層と中間接着層を相溶させ、
インク層のはがれを防ぎくり返し転写特性の良い
インクシートを提供することにより達成できる。 The purpose of the present invention is to solve this conventional drawback by heating the ink sheet from the base material side to make the ink layer and intermediate adhesive layer compatible;
This can be achieved by providing an ink sheet that prevents the ink layer from peeling off and has good repeat transfer characteristics.
ところで、基材中間層、インク層の三層よりな
る熱転写インクシートは、熱効率と転写のくり返
し性向上の点から中間層を薄くインク層を厚くし
たい。しかし中間層を薄くすると転写時にインク
層が中間層の界面からはがれてしまうことがあ
る。これは中間層が薄いと接着効果が十分に発揮
されないことによる。 By the way, in a thermal transfer ink sheet consisting of three layers, a base intermediate layer and an ink layer, it is desirable to make the intermediate layer thin and the ink layer thick in order to improve thermal efficiency and repeatability of transfer. However, if the intermediate layer is made thin, the ink layer may peel off from the interface of the intermediate layer during transfer. This is because if the intermediate layer is thin, the adhesive effect is not sufficiently exhibited.
本発明は中間層の熱熔融性接着剤を軟化し、イ
ンク層に浸透させることにより中間層が薄くても
十分に接着力を持たせるようにしたものであり、
またインクシートの基材側から加熱することによ
りインク層中の溶剤の蒸発をすみやかに行なえる
ようにしたものである。 In the present invention, the hot-melt adhesive in the intermediate layer is softened and allowed to penetrate into the ink layer, so that even if the intermediate layer is thin, it has sufficient adhesive strength.
Further, by heating the ink sheet from the base material side, the solvent in the ink layer can be quickly evaporated.
以下添付図面に沿つて本発明の一実施例を説明
する。 An embodiment of the present invention will be described below with reference to the accompanying drawings.

さで塗布する。 The figure is a cross-sectional view of a thermal transfer ink sheet according to the present invention, in which a 12 μm capacitor paper 3 as a base material is coated with an intermediate layer 2 having a thickness of 6 μm, which is made by dispersing fine carbon black powder in a heat-melting polyamide adhesive.

た。 On top of that, an ink layer 1 in which carbon black is dispersed in an ink material is applied to a thickness of 30 μm. 10 minutes after applying the ink, the ink sheet is heated for 10 seconds from the base material side of the capacitor paper with hot air at 120°C using blower 4. This thermal transfer ink sheet is completed by leaving it for 5 minutes after heating. When this ink sheet was used for transfer, the following effects were obtained.
１ 中間層は6μｍの厚さでもインク層はインク
リボンからはく離することはなく、インク材の
みが記録紙に浸透転写されてくり返し転写が安
定にできる。1 Even though the intermediate layer has a thickness of 6 μm, the ink layer does not peel off from the ink ribbon, and only the ink material is penetrated and transferred to the recording paper, allowing stable repeated transfer.
２ インク層中の溶剤が完全に蒸発するので、溶
剤蒸発による経時変化がない。2. Since the solvent in the ink layer completely evaporates, there is no change over time due to solvent evaporation.
３ インクシートの基材側から加熱するので、熱
風あるいは溶剤蒸発に伴なうインク層表面の変
形がなく印字品質の劣化がない。3. Since the ink sheet is heated from the base material side, there is no deformation of the ink layer surface due to hot air or solvent evaporation, and there is no deterioration in printing quality.
以上の本発明によれば、中間層を薄くしてもイ

上する効果がある。 According to the present invention described above, even if the intermediate layer is made thinner, the ink layer cannot be separated from the ink ribbon, and the ink layer can be made thicker, so that the repeatability of transfer is improved.
