本発明は感熱記録体に関し、特に記録濃度が高く光沢に

のである。DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a heat-sensitive recording medium, and particularly to a heat-sensitive recording medium that has high recording density, excellent gloss, and excellent recording running properties.
「従来の技術」
従来、感熱ヘッドの熱エネルギーにより発色可能な感熱
記録体は良く知られている。かかる感熱記録体は比較的
安価であり、また記録機器がコンパクトでかつその保守

要な発色を生じる欠点がある。"Prior Art" Conventionally, thermal recording materials capable of developing color using thermal energy of a thermal head are well known. Such thermal recording media are relatively inexpensive, and the recording equipment is compact and maintenance is relatively easy, so they are used not only as recording media for facsimile machines and various computers, but also in a wide range of fields such as thermal labels. ing. However, it has problems in fingerprint resistance and solvent resistance, and has the disadvantage that, for example, when the recording layer comes into contact with human sebum or a solvent, the recording density decreases and unnecessary color development called background fog occurs.
このような欠点を解消する方法として、感熱記録層上に
、フィルム形成能を有し、かつ耐薬品性のある樹脂の水
性エマルジョンを塗布する方法(特開昭54−1283
47)、ポリビニルアルコール等の水溶性高分子化合物
を塗布する方法(実開昭56−125354)等が提案
されている。As a method to eliminate these drawbacks, a method is proposed in which an aqueous emulsion of a resin having film-forming ability and chemical resistance is coated on the heat-sensitive recording layer (Japanese Patent Application Laid-Open No. 1283-1983).
47), a method of applying a water-soluble polymer compound such as polyvinyl alcohol (Utility Model Application Publication No. 56-125354), and the like have been proposed.
しかし、改良に伴い新たな欠点が付随し、必ずし・ も
満足すべき結果が得られていないのが現状である。However, improvements have come with new drawbacks, and the current situation is that satisfactory results have not always been obtained.
例えば、感熱記録層上に水性樹脂コーティングを施す場
合には、高温乾燥に伴う記録層の発色を避けるため乾燥
温度を制限する必要があり、必然的に樹脂層の硬化が不
充分となり、記録時に記録ヘッドと樹脂層とが粘着する
現象などが発生する。For example, when applying a water-based resin coating on a heat-sensitive recording layer, it is necessary to limit the drying temperature to avoid coloring of the recording layer due to high-temperature drying, which inevitably results in insufficient curing of the resin layer and A phenomenon in which the recording head and the resin layer stick together occurs.
そのため、顔料、潤滑剤、硬化剤などを添加することに
より記録走行性の向上を計ってきた。Therefore, efforts have been made to improve recording running properties by adding pigments, lubricants, hardening agents, and the like.
一方、近年写真調の高品位な画像を提供するビデオプリ

められている。そして、このような感熱記録体において
も記録像の保存性を改良するために、記録層上に水性樹
脂等の上塗り層を設ける試みが為されている。On the other hand, in recent years, various types of printers such as video printers that provide photographic-like high-quality images have come into use, and thermal recording materials used for printouts are also required to have better recording density and gradation. ing. For this reason, progress is being made in the development of heat-sensitive recording materials with excellent gradation expression using plastic films, coated paper, or highly smooth coated paper as supports. In order to improve the storage stability of recorded images in such heat-sensitive recording materials, attempts have been made to provide an overcoat layer of water-based resin or the like on the recording layer.
しかし、水性樹脂より成る上塗り層を設けた記録体を、

も必ずしも満足すべき状況ではなかった。However, recording media with an overcoat layer made of water-based resin,
Especially when recording with a video printer under high humidity conditions, the overcoat layer will stick to the recording head and paper feed guide.
The problem of clogging often occurs, and the conventional overcoat layer does not provide a high-gloss surface, and the recording density itself is not necessarily satisfactory.

録体は得られていない。Furthermore, when finished as thermal paper for adhesive labels, a high degree of resistance to plasticizers and oils contained in vinyl chloride film is required, but a thermal recording material with satisfactory storage stability has not been obtained.

られることを見出し、本発明を完成するに至った。"Problems to be Solved by the Invention" In view of the current situation, the inventors of the present invention have conducted extensive research into solving the above-mentioned drawbacks, and have found that by providing a specific overcoat layer on the heat-sensitive recording layer, the recording head It was discovered that a heat-sensitive recording material that does not cause the sticking phenomenon, has extremely excellent recording running properties, has high gloss, high recording density, and has excellent storage stability, and completed the present invention. It's arrived.

る。In addition, in order to further improve various storage properties, plasticizer resistance, etc. of the heat-sensitive recording material, a curing agent is added to the paint forming the overcoat layer. Examples of the curing agent for crosslinking the modified silicone oil include glyoxal, methylolmelamine, potassium persulfate, ammonium persulfate, sodium persulfate, ferric chloride, magnesium chloride, boric acid, alum, ammonium chloride, and the like. In particular, boric acid is suitable for a system of polyvinyl alcohol and epoxy-modified silicone oil, and glyoxal is suitable for a system of polyvinyl alcohol and amino-modified silicone oil. These systems can be cured at low temperatures and are particularly suitable as an overcoat layer coated on a heat-sensitive recording layer. These crosslinkable modified silicone oils are fixed in the overcoat layer by a curing agent, so they do not adversely affect storage stability, but non-crosslinkable silicone oils are not fixed in the overcoat layer, so the recording layer discolors or desensitizes.

This is preferable because it not only reduces the influence of oil and plasticizer from the back side, but also allows the thermal recording material to be replaced with excellent storage stability of recorded images. Furthermore, in order to eliminate the influence of oil, plasticizer, etc. from the back side, a back barrier layer containing an adhesive and a pigment as main components can be provided on the back side of the recording medium to further improve the storage stability. As the adhesive and pigment used in these undercoat layer and back barrier layer, those used in the heat-sensitive recording layer described above can be used.
