Abstract
Description
本発明はサーマルヘッド等を介して昇華性染料を熱転写することにより画像を記録し、印画物を作成するために用いられる熱転写受像シートに関する。 The present invention relates to a thermal transfer image-receiving sheet used for recording an image by thermally transferring a sublimable dye via a thermal head or the like to prepare a printed matter.
デジタルカメラ等で撮影した画像を印刷する方式としては、インクジェット方式、昇華転写記録方式が主流である。昇華転写記録方式はインクジェット方式と比して階調表現に優れるという利点がある。 As a method for printing an image taken with a digital camera or the like, an inkjet method or a sublimation transfer recording method is mainly used. The sublimation transfer recording method has an advantage of excellent gradation expression as compared with the ink jet method.
昇華性熱転写方式は、プリンタの高機能化と併せて各種画像を簡便に形成できるため、身分証明書などのカード類を始め、アミューズメント用出力物等に広く利用されている。このように用途の多様化と供に、得られる印画物への耐久性を求める声も大きくなり、最近では上記のような昇華性熱転写記録媒体により形成された画像等の上に熱転写保護層を転写し、耐久性をより向上させる方法が普及してきている。 The sublimation thermal transfer method can be easily formed with various functions of a printer, and is therefore widely used for cards such as identification cards, amusement output products, and the like. In this way, with the diversification of applications, there has been a growing demand for durability on the obtained prints, and recently, a thermal transfer protective layer has been formed on the image formed by the sublimation thermal transfer recording medium as described above. A method of transferring and improving the durability is becoming widespread.
このような熱転写保護層を有する昇華性熱転写記録媒体においては、近年、高速化という観点から、プリンタにより印画されて排出されてくる多量の印画物の捌き性を向上させたいという要求も一段と強くなってきている。 In the sublimation thermal transfer recording medium having such a thermal transfer protective layer, in recent years, from the viewpoint of speeding up, there is an increasing demand for improving the dispersibility of a large amount of printed matter printed and discharged by a printer. It is coming.
また、多量に印画した際に静電気の帯電によってプリンタの紙詰まりが発生することがある。このような課題を解決するために熱転写保護層の帯電量の低減や微粒子の添加、熱転写受像シートの帯電列の調整方法について検討がなされている。 In addition, when a large amount of printing is performed, a paper jam of the printer may occur due to electrostatic charging. In order to solve such problems, studies have been made on methods for reducing the charge amount of the thermal transfer protective layer, adding fine particles, and adjusting the charge train of the thermal transfer image receiving sheet.
例えば、そうした帯電の調整のため、四級アンモニウム塩からなる界面活性やアンチモン酸亜鉛等の導電性金属酸化物を含有させてなる、帯電防止機能を付与した熱転写保護層を有する昇華性熱転写記録媒体が提案されている（特許文献１）。 For example, a sublimation thermal transfer recording medium having a thermal transfer protective layer imparted with an antistatic function, which contains a conductive metal oxide such as a surface activity made of a quaternary ammonium salt or zinc antimonate for adjusting the charge. Has been proposed (Patent Document 1).
しかしながら、帯電防止機能を十分に発現させるためには、熱転写保護層に帯電防止剤を多量に添加する必要があり、製造コストの上昇と印画物の保存性能、透明性の低下という問題がある。また、熱転写受像シートの背面については帯電防機能を付与していないため、捌き性が悪化してしまう。 However, in order to fully exhibit the antistatic function, it is necessary to add a large amount of an antistatic agent to the thermal transfer protective layer, which causes problems of an increase in production cost, storage performance of printed matter and transparency. Moreover, since the antistatic function is not given to the back surface of the thermal transfer image receiving sheet, the curling property is deteriorated.
また、受容層または背面層にイオン液体を含有させてなる、帯電防止機能を付与した熱転写受像シートが提案されている（特許文献２）。 In addition, a thermal transfer image receiving sheet having an antistatic function, which contains an ionic liquid in the receiving layer or the back layer, has been proposed (Patent Document 2).
しかしながら、イオン液体は常温で液体であることから、搬送部材への汚染が懸念される。また、低温低湿度環境下や連続で印画を行うことによりプリンタ内に静電気が蓄積することで帯電防止機能が低下し、捌き性が悪化してしまう。 However, since the ionic liquid is a liquid at normal temperature, there is a concern about contamination of the conveying member. Moreover, static electricity is accumulated in the printer by performing printing in a low-temperature and low-humidity environment or continuously, so that the antistatic function is lowered and the curling property is deteriorated.
また、熱転写受像シートの背面層にスチレンアクリル共重合樹脂を含み、プリンタのローラー表面部材がポリオキシメチレン樹脂を含むことで、印画物の帯電を調整する熱転写システムが提案されている（特許文献３）。 Further, a thermal transfer system has been proposed in which the back layer of the thermal transfer image-receiving sheet contains a styrene acrylic copolymer resin, and the roller surface member of the printer contains a polyoxymethylene resin, thereby adjusting the charging of the printed matter (Patent Document 3). ).
しかしながら、上記提案では、熱転写受像シートの帯電量を調整することができるが、背面層の材料とプリンタのローラーの帯電列から使用できる材料が限定されてしまうことにより、背面層に要求される特性を損なうことがある。また、連続で印画を行うことによりプリンタ内に静電気が蓄積することで捌き性が悪化してしまう。 However, in the above proposal, the charge amount of the thermal transfer image-receiving sheet can be adjusted. However, the characteristics required for the back layer are limited by the fact that the material that can be used from the back layer material and the charge train of the printer roller is limited. May be damaged. In addition, since printing is continuously performed, static electricity is accumulated in the printer, and the curling property is deteriorated.
本発明はこのような事情を鑑みて成されたものであり、熱転写受像シートの背面層に要求される機能を損なうことなく、印画物の帯電量を抑制することで、良好な捌き性および排紙性が確保できる熱転写受像シートを提供することを目的とする。 The present invention has been made in view of such circumstances, and by suppressing the charge amount of the printed matter without impairing the function required for the back layer of the thermal transfer image-receiving sheet, it is possible to achieve good repellency and discharge. It is an object of the present invention to provide a thermal transfer image receiving sheet capable of ensuring paper properties.

<Preparation of print 6>
Using the sublimation thermal transfer recording medium and thermal transfer image-receiving sheet 1 obtained in Examples 1 to 5 and Comparative Example 1, a full-screen black image (solid black) with the highest density was printed by a thermal printer for evaluation.
＜帯電量測定＞

<Charge amount measurement>
Using a digital electrostatic potential measuring device KSD-1000 (manufactured by Kasuga Denki Co., Ltd.), the charge amount (Va) of the back layer of the thermal transfer image-receiving sheet 1 of the printed material 6 discharged from the evaluation thermal printer was measured.
＜捌き性評価＞
捌き性の評価は、評価用サーマルプリンタより排出される印画物３０枚を乱雑に積み重ね、４隅のズレ量が２ｍｍ以内に整えることができるかにより判断した。
評価基準は、
○：印画物同士が貼り付かず、容易に整えることができる
△：印画物同士に軽微な貼り付きがあるが、整えることができる
×：印画物同士に貼り付きがあり、整えることができない
とし、○および△が実用上問題ないレベルである。
<Sparkling evaluation>
The evaluation of the glaring property was judged based on whether or not 30 prints discharged from the evaluation thermal printer were randomly stacked and the amount of misalignment at the four corners could be adjusted within 2 mm.
Evaluation criteria are
○: The prints do not stick to each other and can be easily arranged. Δ: The prints have a slight sticking between them, but they can be arranged. , ◯ and Δ are levels that are not problematic in practice.
＜排紙性評価＞
排紙性の評価は、評価用サーマルプリンタにて低温低湿度環境（１０℃２０％）下で連続印画を行い、排出される印画物が排紙口でつまりが発生しないか確認した。
評価基準は、
○：排紙口でつまらずに排紙することができる
×：排紙口でつまり、排紙することができない
とした。
<Ejection evaluation>
The evaluation of paper discharge performance was carried out by continuously printing with a thermal printer for evaluation under a low temperature and low humidity environment (10 ° C., 20%), and it was confirmed whether the discharged printed matter was clogged at the paper discharge port.
Evaluation criteria are
○: Paper can be discharged without boring at the paper discharge port. X: That is, paper cannot be discharged at the paper discharge port.
以上結果を表１に示す。 The results are shown in Table 1.
また、背面側の帯電量（Ｖａ）が、｜Ｖａ｜＜０．２０ｋｖである実施例１〜３は良好な捌き性を示したが、範囲外の実施例４、５は軽微な貼り付きがあり、背面側の帯電量（Ｖａ）が｜Ｖａ｜＜０．２０ｋｖの範囲にあることが捌き性にはより好適であることが分かった。 In addition, Examples 1 to 3 in which the charge amount (Va) on the back side was | Va | <0.20 kv showed good scratching properties, but Examples 4 and 5 outside the range had slight sticking. In other words, it was found that the charge amount (Va) on the back surface side was in the range of | Va | <0.20 kv, which is more suitable for spreading.
