る。[Prior Art and Problems] Recently, the heat-sensitive transfer recording sheet has been increasingly used in label printers and bar code printers. However, wax is used in the heat-sensitive transfer layer of the conventional heat-sensitive transfer recording sheet. Since the binder as the main component is used, the printing has poor heat resistance, abrasion resistance, oil resistance, chemical resistance, etc., and there is a problem that it cannot be used for the above-mentioned applications.

トを得ることに成功した。[Means for Solving Problems] As a result of earnest research to solve the above problems, the present inventor has found that by using a specific binder as a binder of the heat-sensitive transfer layer, heat resistance, abrasion resistance, and oil resistance are improved. sex,
We succeeded in obtaining a heat-sensitive transfer recording sheet capable of printing with excellent chemical resistance.

Examples include plastic films such as polyester, polycarbonate, triacetyl cellulose, nylon, and polyamide, and sulfuric acid paper, glassine paper, and condenser paper.
支持体の上に設ける感熱性転写層は、着色剤10〜30重
量部、アクリル−スチレン共重合体樹脂30〜89重量部、
ポリエステル樹脂１〜30重量部および滑剤０〜20重量部
をトルエンやメチルエチルケトンなどの有機溶剤に溶解
し、これを１〜４μｍ（乾燥時）の厚みになる割合で塗
布および乾燥することによって形成される。The heat-sensitive transfer layer provided on the support, the colorant 10 to 30 parts by weight, acrylic-styrene copolymer resin 30 to 89 parts by weight,
Formed by dissolving 1 to 30 parts by weight of a polyester resin and 0 to 20 parts by weight of a lubricant in an organic solvent such as toluene or methyl ethyl ketone, and applying and drying the solution at a ratio of 1 to 4 μm (dry). .
使用する着色剤としては、カーボンブラック、酸化チ
タン、酸化鉄、アルミニウム、銅、雲母などの微粉末無
機顔料、各種の有機顔料、蛍光顔料又は染料などが使用
される。使用量が少なすぎると印字の濃度が低く、多す
ぎると転写層の強度が低下し、又、印字熱感度も低下す
る。As the colorant to be used, fine powder inorganic pigments such as carbon black, titanium oxide, iron oxide, aluminum, copper and mica, various organic pigments, fluorescent pigments or dyes are used. If the amount used is too small, the printing density will be low, and if it is too large, the strength of the transfer layer will decrease and the thermal sensitivity of printing will also decrease.
アクリル−スチレン共重合体樹脂は、ガラス転移点が
50℃以上で、分子量が20〜500×103程度のものが好適で
ある。使用量が少なすぎると被膜強度が不十分である。Acrylic-styrene copolymer resin has a glass transition point
Those having a temperature of 50 ° C. or higher and a molecular weight of about 20 to 500 × 10 3 are suitable. If the amount used is too small, the film strength will be insufficient.
ポリエステル樹脂は、ガラス転移点が30℃以上の飽和
熱可塑性で、上記アクリル−スチレン共重合体樹脂と相
溶性のあるものが好ましい。The polyester resin is preferably a saturated thermoplastic resin having a glass transition point of 30 [deg.] C. or higher and compatible with the acrylic-styrene copolymer resin.
使用量が１重量部未満では、転写層と支持体の密着性
や印字性を向上させる効果が十分には期待できない。
又、30重量部を越える使用量では転写層の支持体からの
剥離性が不足し、印字物の耐熱性も低下する。If the amount used is less than 1 part by weight, the effect of improving the adhesiveness between the transfer layer and the support and the printability cannot be expected sufficiently.
Further, when the amount used exceeds 30 parts by weight, the releasability of the transfer layer from the support becomes insufficient, and the heat resistance of the printed matter also decreases.
転写層には滑剤を転写層の20重量％まで加えることが
好ましい。滑剤としてはポリエチレンワックス、酸化ポ
リエチレン、ポリテトラフルオロエチレン、合成パラフ

ス、ポリテトラフルオロエチレン、脂肪酸アミド系、金
属石鹸系などが好ましい。It is preferable to add a lubricant to the transfer layer up to 20% by weight of the transfer layer. Examples of lubricants include polyethylene wax, polyethylene oxide, polytetrafluoroethylene, synthetic paraffin, chlorinated hydrocarbons, microwax, natural paraffin, liquid paraffin and other hydrocarbon-based, fatty acid-based, fatty acid amide-based, fatty acid ester-based, alcohol-based, metal Although there are soaps and the like, polyethylene wax, oxidized polyethylene wax, polytetrafluoroethylene, fatty acid amides, metal soaps and the like are preferable in consideration of heat resistance and abrasion resistance.
