Description
【０００１】[0001]
本考案は、熱発色系が反応して発色画像が得られる感熱記録紙に関し、保存性 が優れ、かつ両面に発色画像が得られる両面感熱記録紙に関するものである。 The present invention relates to a thermosensitive recording paper on which a thermochromic system reacts to obtain a colored image, and more particularly to a double-sided thermosensitive recording paper having excellent storability and capable of forming a colored image on both sides.
【０００２】[0002]
感熱記録紙はファクシミリやプリンターの記録媒体として広く使用されている が最近は各種プリンターの用途拡大に伴って記録物の耐薬品性および長期保存性 が優れ、かつ両面に感熱記録が可能な両面感熱記録紙の要求がたかまっている。 上記の保存性が優れ、かつ両面に記録が可能な両面感熱記録紙は、一般に上質 紙、合成紙、プラスチックフィルム等の支持体の表面および裏面の両面に熱発色 系反応物を主成分とする感熱層を設け、さらに両面の各感熱層の上に水溶性樹脂 若しくは疎水性樹脂を主成分とした保護層を塗布することによって製造されてい るのが実情である。 Thermal recording paper is widely used as a recording medium for facsimiles and printers, but recently, due to the expansion of the use of various printers, the recorded materials have excellent chemical resistance and long-term storability, and double-sided thermal recording that enables thermal recording on both sides. The demand for recording paper is high. The above double-sided thermal recording paper that has excellent storage stability and is capable of recording on both sides is generally composed mainly of thermochromic reaction products on both the front and back surfaces of a support such as high-quality paper, synthetic paper, and plastic film. In reality, it is manufactured by providing a heat-sensitive layer and further applying a protective layer containing a water-soluble resin or a hydrophobic resin as a main component on each heat-sensitive layer on both sides.
【０００３】 しかし、上記方法による両面感熱記録紙の製造において、片面に感熱層を塗布 し残る片面に感熱層を塗布する際に乾燥温度を低くする必要があるため塗布速度 の低下を伴い、その結果として白色度維持が困難であるだけでなく生産効率が悪 くなる欠点を有していた。また、厚さが１００μｍを越えるような厚手の支持体 を使用する場合には、アンリール部支持体ロールの巻外径に限界があるため必然 的にアンリール部支持体ロールの巻長さが限定され、また、保護層を塗布するこ とによって工程が増加するため塗工歩留まりの低下が避けられないという難点が あった。However, in the production of a double-sided heat-sensitive recording paper by the above method, it is necessary to lower the drying temperature when the heat-sensitive layer is applied to one side and the heat-sensitive layer is applied to the remaining one side, so that the coating speed is lowered, As a result, it has a drawback that it is difficult to maintain whiteness and production efficiency is poor. Further, when a thick support having a thickness of more than 100 μm is used, there is a limit to the winding outer diameter of the unreel part support roll, which inevitably limits the winding length of the unreel part support roll. In addition, there is a problem in that the coating yield cannot be avoided because the number of steps is increased by applying the protective layer.
【０００４】[0004]
本考案は、従来の両面感熱記録紙の上述のような製造上の問題を伴うことなく 、生産効率および塗工歩留まりを向上し、かつ感熱層の両面に保護層が設けるこ とにより、耐薬品性および保存性に優れた厚手の両面感熱記録紙を安価に提供す ることにある。 The present invention improves the production efficiency and the coating yield without the above-mentioned problems in the production of the conventional double-sided thermal recording paper, and by providing the protective layers on both sides of the thermal sensitive layer, chemical resistance is improved. The purpose is to provide a thick double-sided thermal recording paper that is excellent in durability and storability at low cost.
