【発明の詳細な説明】
〔技術分野〕
本発明は感熱記録材料に関し、更に詳しくはロイコ染料
と顕色剤との間の発色反応を利用した感熱記録材料に関
する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a heat-sensitive recording material, and more particularly to a heat-sensitive recording material that utilizes a color-forming reaction between a leuco dye and a color developer.
通常、無色ないし淡色の発色性ロイコ染料と有機酸性物
質のような顕色剤とが熱時、溶融反応して発色すること
は古くから知られており、この発色反応を記録紙に応用
した例は、特公昭43−4160号公報、特公昭45−
14039号公報等に開示されており公知である。これ
らの感熱記録シートは計測用レコーダー、コンピュータ
ー等の端末プリンター、ファクシミリ、自動券売機、バ
ーコードラベルなど広範囲の分野に応用されているが、
最近はこれら記録装置の多様化、高性能化が進められる
に従って、感熱記録シートに対する要求品質もより高度
なものとなっている。例えば、サーマルヘッドの高速化
に伴い微小な熱エネルギーでも高濃度で鮮明な画像を記
録でき、かつスティッキング、ヘッドカス等のヘッドマ
ツチング性が良好な感熱記録シートが要求されている。It has been known for a long time that color-forming leuco dyes, which are normally colorless or light-colored, and color developers such as organic acidic substances melt and react when heated, producing color. Examples of applications of this color-forming reaction to recording paper are published in Japanese Patent Publication No. 43-4160, Publication No. 45-
It is disclosed in Japanese Patent No. 14039 and the like and is well known. These thermal recording sheets are used in a wide range of fields, including measurement recorders, computer terminal printers, facsimile machines, automatic ticket vending machines, and barcode labels.
Recently, as these recording devices have become more diversified and more sophisticated, the quality required for heat-sensitive recording sheets has also become more sophisticated. For example, as the speed of thermal heads increases, there is a demand for thermal recording sheets that can record high-density, clear images even with minute thermal energy and that have good head matching properties such as sticking and head dregs.
感熱記録シートの発色は、発色性ロイコ染料及び顕色剤

公報に開示されている。例えば、特開昭49−3484
2号公報にはアセトアミド、ステアロアミド、 m −

が、特開昭52−106746号公報にはアセト酢酸ア
ニリドが、特開昭53−39139号公報にはアルキル
化ビフェニルアルカンが開示されている。The coloring of the heat-sensitive recording sheet is caused by a reaction in which the color-forming leuco dye and/or the color developer are dissolved by thermal energy supplied from the thermal head.
One way to improve color development sensitivity is to add a compound (generally called a thermofusible substance) that melts at a lower temperature than the leuco dye and color developer and has a high ability to dissolve both. It is widely known, and various compounds are disclosed in the following publications. For example, JP-A-49-3484
Publication No. 2 contains acetamide, stearamide, m −
Nitrogen-containing compounds such as nitroaniline and dinitrile phthalate are disclosed, acetoacetanilide is disclosed in JP-A-52-106746, and alkylated biphenyl alkanes are disclosed in JP-A-53-39139.

Therefore, it has become a challenge to increase the dynamic color development sensitivity without lowering the color development start temperature. However, although the above compounds improve the static coloring sensitivity, sufficient dynamic coloring sensitivity cannot be obtained unless they are added in large quantities to the thermosensitive coloring layer. ), or
If sticking occurs or if the melting point is too low, the storage stability (background fog) on the heat-sensitive recording sheet 1 will be reduced, making it impossible to obtain fully satisfactory results.

も十分満足のいく結果が得られない。In addition, one method for improving dynamic coloring sensitivity is to improve the smoothness of the surface of the thermosensitive coloring layer, or to add components that do not participate in the coloring reaction in the coloring layer, such as fillers and binders containing r-M. There is also a method of reducing the amount and increasing the density of the coloring component. Improving the surface smoothness can be easily achieved by calendering using a super calender or the like, but this can cause the background color to develop and the surface gloss to be high, which greatly impairs the appearance of the paper as a recording paper. . Note that fillers such as calcium carbonate, clay, urea-formalin resin, etc. are usually added to the heat-sensitive coloring layer to maintain the whiteness of the background, to prevent adhesion of residue to the head, and to prevent sticking. A water-soluble binder is added to fix the additives to the support, but reducing the content of these binders will inevitably lead to deterioration of the quality described above and cause inconveniences, so this method is not fully satisfactory. I can't get good results.

No. 59-5093 and No. 59-171685. However, with these, the smoothness of the surface of the heat insulating layer is significantly impaired, making it difficult to obtain a uniform image and not achieving satisfactory results. It has been proposed to improve thermal sensitivity by providing a laminated foam layer formed by foaming a filler and an undercoat layer containing a filler and a binder between the support and the thermosensitive coloring layer. However, this recording material has the disadvantage that it is accompanied by an increase in cost due to the complexity of the manufacturing process.
