【発明の詳細な説明】
〔産業上の利用分野〕
本発明は感熱記録材料に関し、更に詳しくは、高光沢を
有し、しかもヘッドマツチング性、画像信頼性及び印刷
適性の良好な感熱記録材料に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a heat-sensitive recording material, and more specifically, a heat-sensitive recording material that has high gloss and has good head matching properties, image reliability, and printability. Regarding.
感熱記録材料は、加熱により発色する感熱発色層を１紙
、合成紙、樹脂フィルム等の支持体上に形成した構造の
記録材料であって、その発色のための加熱には、熱ヘツ
ドを内蔵したサーマルプリンター等が用いられている。A thermosensitive recording material is a recording material with a structure in which a thermosensitive coloring layer that develops color when heated is formed on a support such as paper, synthetic paper, or resin film, and a built-in thermal head is used to heat the material to develop the color. Thermal printers and the like are used.
この記録方法は他の方法に比べ、現像、定着等の処理を
施す必要がなく、比較的簡単な装置を用いて短時間で記
録することができる上にコストが安い等という利点があ
り１図書、文書等の複写の他、ファクシミリ−券売機、
ラベルレコーダー等の多方面に用いられている。Compared to other methods, this recording method has the advantage that it does not require processing such as development and fixing, can be recorded in a short time using relatively simple equipment, and is inexpensive. In addition to copying documents, facsimile machines, ticket vending machines, etc.
It is used in many ways such as label recorders.
た）′、このような感熱記録材料の問題点として。 )', as a problem with such heat-sensitive recording materials.
熱ヘツドに感熱発色層中の成分が付着すること（カス付
着）に伴なう熱ヘツドの走行性の妨げやステッキング、
ヘッド摩耗等があり、また券紙、ラベル等で使用する際
の画像信頼性（耐油性、耐水性、耐可塑剤性）が不充分
であるとか、更には商品化レベルでの印刷適正（インク
ののり、接着力）が普通紙に比較して劣る等ということ
がある。The adhesion of components in the heat-sensitive coloring layer to the thermal head (residue adhesion) may impede the runnability of the thermal head or cause sticking.
There is head abrasion, image reliability (oil resistance, water resistance, plasticizer resistance) when used on ticket paper, labels, etc. is insufficient, and printing suitability at the commercial level (ink ink) is insufficient. In some cases, the adhesive strength (glue and adhesive strength) may be inferior to that of plain paper.
これらの点を改善する目的で、従来から感熱発色層上に
保護層を設けることが行なわれ、この保護層を構成する
成分としては、樹脂、架橋剤、無機・有機顔料、滑剤、
界面活性剤等が用いられているが、このような保護層の
塗設によっても、改善の程度は未だ不充分である。In order to improve these points, a protective layer has traditionally been provided on the thermosensitive coloring layer, and the components that make up this protective layer include resins, crosslinking agents, inorganic/organic pigments, lubricants,
Surfactants and the like have been used, but even with the application of such a protective layer, the degree of improvement is still insufficient.
しかも、最近ではラベル等で高級感をだすために、高光
沢を有する感熱記録材料が要求されており、前記のよう
な成分を主とする保護層では、無機・有機顔料を使用す
るため、高光沢を有するものがなく、そのために商品化
後、印刷時に紫外線硬化性樹脂等をコーティングするこ
とにより高光沢化することが行なわれているが、該方法
は現状ではコストが高くしかもひび割れする（少しの外
力で亀裂が生じ１画像信頼性が低下する）という欠点が
ある。Moreover, in recent years, there has been a demand for heat-sensitive recording materials with high gloss to give a luxurious feel to labels, etc., and the protective layer, which mainly consists of the above-mentioned ingredients, uses inorganic and organic pigments. There is no glossy product, and therefore, after commercialization, printing is coated with ultraviolet curable resin to increase gloss, but this method is currently expensive and cracks (a little). There is a drawback that cracks occur due to external force, reducing the reliability of one image.
従って、本発明は前記従来技術の問題点を克服した、低
コストで且つ高光沢を有する感熱記録材料を提供するこ
とを目的とする。Therefore, an object of the present invention is to provide a heat-sensitive recording material that overcomes the problems of the prior art and has high gloss at low cost.

表面光沢度が７５｛ＧＳ（７５”）｝％以上であること
を特徴とする感熱記録材料が提供される。According to the present invention, in a heat-sensitive recording material in which a heat-sensitive coloring layer containing a leuco dye and a color developer as main components is provided on a support, a protection film containing an aliphatic urethane resin as a main component on the heat-sensitive coloring layer is provided. Provided is a heat-sensitive recording material having a layer and having a surface gloss of 75 {GS (75'')}% or more based on JIS-P-8142.

ことを見出し、本発明に到達した。The present inventors have conducted intensive studies to improve head matching properties without adding inorganic or organic pigments in forming the protective layer, and as a result, the inventors have determined that an aliphatic urethane resin is used as the resin constituting the protective layer. As a result, head matching performance, image reliability, and printability are improved, and J

橋剤、滑剤分散液を配合し、撹拌して調製する。The heat-sensitive recording material of the present invention can be produced by a generally known method. For example, first, a leuco dye and a color developer are separately mixed with an aqueous binder solution using a dispersing machine such as a ball mill, attritor, or sand mill to obtain a dispersed particle size of 1 to 3.
After pulverizing and dispersing the powder to a size of μm, the powder is mixed with a filler, a dispersion of a thermofusible substance, etc. according to a predetermined formulation to prepare a coating solution for a heat-sensitive coloring layer. On the other hand, the protective layer coating solution is prepared by adding a crosslinking agent and a lubricant dispersion as necessary to an aqueous solution or emulsion of an aliphatic urethane resin, and stirring the mixture.
