【発明の詳細な説明】
〔技術分野〕
本発明は、三層積層構成の熱転写性インク層を有し、表
面の平滑性が劣った被転写紙にも地汚れのない鮮明な記
録を可能にすると共に非印字部のこすれによる地汚れを
防止し得る転写型感熱記録媒体に関する。[Detailed Description of the Invention] [Technical Field] The present invention has a thermally transferable ink layer with a three-layer laminated structure, and enables clear recording without scumming even on transfer paper with poor surface smoothness. The present invention also relates to a transfer type heat-sensitive recording medium which can prevent scumming due to rubbing in non-printed areas.
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

)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 (Japanese Patent Application Laid-Open No. 59-224392
Techniques have been proposed, such as providing a layer made of a heat-fusible substance containing no coloring material on a heat-fusible ink layer (Japanese Patent Laid-Open No. 60-97888).
しかしながら、このように溶融して液体となりたインク
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 is low in smoothness, the print quality will still be poor compared to the print quality on transfer paper with a high surface smoothness. It has not been possible to fundamentally solve the drawbacks of transfer-type thermal recording, in which only inferior print quality is obtained and print quality depends on the smoothness of the surface of the transfer paper.

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, it is possible to print with high quality on a transfer paper whose surface has poor 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.

必要があり、このため感熱転写媒体の保存性や塗工性に
難点を生じる。In addition, high boiling point solvents such as phosphoric acid esters, phthalic esters, animal and vegetable oils, mineral oils, higher fatty acids, and higher alcohols are used in the coloring material layer in contact with the heat-resistant support, so that there is no background smearing or deterioration of resolution. Thermal transfer media have also been proposed (Japanese Patent Laid-Open No. 60-239284, Japanese Patent Laid-open No. 60-239285).
This product has low sensitivity and is difficult to print at high speed or with low energy, and in order to prevent the resolution from decreasing, it is necessary to add a large amount of the high boiling point solvent. This causes difficulties in the storage stability and coating properties of the thermal transfer medium.

った。Furthermore, in a thermal transfer material in which a first ink layer and a second ink layer are provided on a support, a method is also known in which mineral oil or vegetable oil such as machine oil, castor oil, olive oil, or rapeseed oil is contained in the first ink layer. (Unexamined Japanese Patent Publication No. 187593/1983)
Although this product has the advantage of being able to print well even in solid black without line breaks in the so-called first ink layer, it has the drawbacks of being prone to scumming and having poor storage stability.

う問題がある。Furthermore, a thermal transfer material has been proposed in which first to third ink layers are provided on a support, and the melt viscosity and cohesive force of the second ink layer are made larger than those of the first and third ink layers. (Japanese Unexamined Patent Publication No. 60-183192), although the transferred image obtained from this method has excellent print density, there is a problem that scumming occurs in non-printed areas when rubbed with an eraser or the like.

In a transfer type heat-sensitive recording medium in which heat-transferable ink layers consisting of heat-softening colored layers prepared so as not to become In addition, since the colorant is contained only in the heat-softening colored layer, it is possible to perform clear printing without background smudges even on transfer paper with poor smoothness. Since it does not cause stains, it has extremely high practical value.
