Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、高品質の印字が可能となる熱転写インクに
関する。TECHNICAL FIELD The present invention relates to a thermal transfer ink capable of high quality printing.
（従来の技術） ベースフィルムに塗布されて熱転写インクリボンを構
成する従来の熱転写インクは、ワックス、樹脂、着色材

いた。(Prior Art) A conventional thermal transfer ink that is applied to a base film to form a thermal transfer ink ribbon has a wax, a resin, a coloring material, and the like as a compounding component. The thermal transfer ink of the thermal transfer ink ribbon loaded in the thermal transfer printer was heated and melted when passing through the thermal head, and was transferred to the transfer target.

写インクの提供を目的とする。(Problems to be Solved by the Invention) By the way, the thermal transfer ink of the above-mentioned conventional example has a problem in that when the particles are minute and the surface of the transferred material has a high degree of unevenness, the thermal transfer ink sinks into the recesses and the printing is unclear. An object of the present invention is to provide a thermal transfer ink that enables clear and high-quality printing even on an object to be transferred such as low smooth paper.

極めて鮮明化する。(Operation) As shown in the figure, the thermal transfer ink (1) of the present invention melts when heated by the thermal head of the thermal transfer printer, and at the same time, the fine powdery granular thermal expansion agent (2) added therein expands. Therefore, even when the ink is transferred from the base film (4) of the ink ribbon (3) to the transfer target (5), the concave portion on the surface is completely closed, and a three-dimensional effect is provided, so that the printing is extremely sharpened.
（実施例） 第１実施例 表１に示された組成のエマルジョンインクに対して、
微小粉粒状熱膨張剤として合成樹脂製の微小空球体であ
るエクスパンセルWU、DUを５〜50％添加する。(Example) First Example For emulsion inks having the compositions shown in Table 1,
5 to 50% of Expancel WU and DU, which are fine hollow spheres made of synthetic resin, are added as a fine powdery thermal expansion agent.
第２実施例 表２に示された組成の溶剤溶解インクに対して上記の
第１実施例と同じエクスバンセルWU、DUを５〜50％添加
する。 Second Example To the solvent-soluble ink having the composition shown in Table 2, 5 to 50% of the same Exvancel WU and DU as in the above-mentioned first example was added.
上記の実施例で使用した熱膨張剤は90℃まで加熱する
と略50倍に膨張する。又、従来のインク組成に略20％添
加するとインク粒子全体は略10倍に膨張する。 The heat-expanding agent used in the above examples expands about 50 times when heated to 90 ° C. When about 20% is added to the conventional ink composition, the whole ink particles expand about 10 times.
尚、上記実施例の熱転写インクを溶剤分散インク塗

ルムに塗布して熱転写インクリボンを構成する場合、上
記したように熱膨張剤が略90℃で膨張するので溶剤乾燥
温度を80℃以下に抑える必要がある。When the thermal transfer ink ribbon of the above-mentioned example is applied to the base film by a method such as solvent-dispersed ink coating or solvent-dissolved ink coating to form a thermal transfer ink ribbon, the thermal expansion agent is approximately 90 ° C. as described above. The solvent drying temperature must be kept below 80 ° C because it will swell.
又、PET、コンデンサー紙、アラミド等の厚さ3.5μの
ベースフィルムに対し上記実施例の熱転写インクを塗布
する場合、溶剤乾燥後の厚さが3.5〜７μとなるよう塗
布すれば極めて高品質の熱転写インクリボンが得られ
る。Further, when the thermal transfer ink of the above-mentioned embodiment is applied to a base film having a thickness of 3.5 μ such as PET, condenser paper, aramid, etc., if the thickness after drying the solvent is 3.5 to 7 μ, it is possible to obtain a very high quality. A thermal transfer ink ribbon is obtained.
