Description
【発明の詳細な説明】 〔技術分野〕 本発明は、積層構成の熱溶融性インク層を有し。[Detailed description of the invention] 〔Technical field〕 The present invention has a thermofusible ink layer having a laminated structure.
表面の平滑性が劣った被転写紙にも鮮明な記録を可能に
すると共に地汚れのない感熱転写記録媒体に関する。To provide a thermal transfer recording medium that enables clear recording even on transfer paper with poor surface smoothness and is free from scumming.
転写型感熱記録方法は、装置が簡便な普通紙記録方法と
して普及しているが、被転写紙の表面の平滑性に印字品
質が左右されやすく、表面の平滑性が劣った被転写紙に
対して鮮明な印字を行なうのが困難である。The transfer type thermal recording method is popular as a plain paper recording method with a simple device, but the print quality is easily affected by the smoothness of the surface of the transfer paper, and it is difficult to use for transfer paper with a poor surface smoothness. It is difficult to print clearly.
このような欠点を改善する為に従来、印字後熱処理をす
る（特開昭５８−７６２７６号）、転写時に磁力（特開
昭５２−９６５４９号）や静電気力（特開昭５５−６５
５９０号）等による補助手段を用いる。あるいは油状物
質を大量に添加しておいて転写時の溶融粘度をさげる（
特開昭６０−２５７６２号）、熱分解性（特開昭６０−
８２３８９号）、熱膨張性（特開昭６０−２５７６２号
）の物質を添加して熱増感する等の手段が提案されてい
る。In order to improve such defects, conventional methods include heat treatment after printing (Japanese Patent Laid-Open No. 58-76276), magnetic force (Japanese Patent Laid-Open No. 52-96549) or electrostatic force (Japanese Patent Laid-Open No. 55-65) during transfer.
No. 590) etc. are used. Alternatively, add a large amount of oily substance to reduce the melt viscosity during transfer (
JP-A-60-25762), thermally decomposable (JP-A-60-25762)
82389) and heat sensitization by adding a thermally expandable substance (Japanese Patent Application Laid-Open No. 60-25762).
また、熱溶融性のインク層を多層化する事により印字品
質を改善しようとする技術も従来提案されており、融点
のみが少しづつ異なる熱溶融性インクを積層し、何れか
又は両方に顔料を添加する（特開ｌＬｉ５９−２２４３
９２号）、熱溶融性インク層の上に色材を含まない熱溶
融性の物質からなる層を設ける（特開昭６０−９７８８
８号）等の技術が提案されている。In addition, a technique has been proposed to improve print quality by layering multiple layers of heat-melt ink, in which heat-melt inks with slightly different melting points are layered, and pigments are added to one or both of them. Add (Unexamined Japanese Patent Application Laid-open No. 1999-2243
No. 92), a layer made of a heat-melt material containing no coloring material is provided on the heat-melt ink layer (Japanese Patent Laid-Open No. 60-9788)
No. 8) and other technologies have been proposed.
しかしながら、このように溶融して液体となったインク
を転写して記録する方法では、被転写紙の表面の平滑性
が低い場合には表面の平滑性が高い被転写紙に対する印
字品質に比較するとやはり劣った印字品質しか得られず
、印字品質が被転写紙の表面の平滑性に依存するという
転写型感熱記録の欠点の根本的解決はできなかった。However, in this method of recording by transferring melted ink that has become a liquid, if the surface of the transfer paper has low smoothness, the print quality will be lower than that of paper with a highly smooth surface. After all, only inferior print quality was obtained, and the fundamental problem of transfer type thermal recording, in which print quality was dependent on the smoothness of the surface of the transfer paper, could not be fundamentally solved.

転写紙に高い品質で印字できる。On the other hand, when thermal energy is applied, the ink, which is mainly composed of a resin that exhibits tackiness but does not melt into a low-viscosity liquid and has a certain degree of mechanical strength, can be applied to transfer paper, which has a poor surface smoothness. By using an ink that adheres to the convex portions of the surface and covers the concave portions, high-quality printing can be performed on transfer paper with poor surface smoothness.

要がある上、サーマルヘッドの寿命や蓄熱の問題が生じ
て好ましくない。However, such resin inks require more energy to print than conventional wax inks, so it is necessary to use a support film with particularly high heat resistance, and it also reduces the lifespan of the thermal head and heat storage. This is not desirable as it causes problems.
この問題を゛解決するために、支持体と前記樹脂インク

インク層の切れをよくする方法が種々提案されている。In order to solve this problem, a heat melting layer is provided between the support and the resin ink layer, and a large amount of a high boiling point solvent is added to the heat melting layer to heat the resin with low energy. Various methods have been proposed to improve the cutting ability of the ink layer.

Although it is possible to print with low energy using high boiling point solvents such as higher alcohols, background smudges occur, and depending on the type, there are some that are not effective unless added in large quantities, and there are issues such as storage stability and coatability. There are many problems with this.
