Abstract

<P>PROBLEM TO BE SOLVED: To provide an organic solvent type antistatic printing ink for a plastic film and a print using the ink. <P>SOLUTION: The ink is prepared by adding an antistatic agent of a mixed composition consisting of an aliphatic acid dimethyl ammonium ethosulfate and a polyoxyethylene alkyl ether to a vehicle binder of an organic solvent solution of an ester form polyurethane resin composed of a mixed composition of high Tg and low Tg. Printing the reverse face of the plastic film with the ink imparts the antistatic property to the plastic film. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本願発明は、透明または半透明なプラスチックフィルム用インキに関し、更に詳しくは、印刷インキの中でも、裏刷り用として用いられるインキに帯電防止性能を付与することにより、プラスチックフィルムの両面において発生する摩擦帯電現象を抑止する効果のあるインキとこのインキで印刷された透明または半透明プラスチックフィルム印刷物に関するものである。   The present invention relates to a transparent or translucent ink for a plastic film. More specifically, among printing inks, triboelectric charge generated on both sides of a plastic film by imparting antistatic performance to ink used for back printing. The present invention relates to an ink having an effect of suppressing the phenomenon and a transparent or translucent plastic film printed matter printed with this ink.

プラスチックフィルムの場合、ラミネート工程あるいは印刷工程あるいは製袋工程などに於いて、摩擦による帯電が発生することから、この帯電を防止する工夫が成されている。この例としては、フィルム製造前の樹脂に帯電防止剤を練り込んでおく方法、およびフィルム表面に帯電防止剤をコートする方法などがある。   In the case of a plastic film, since charging due to friction occurs in a laminating process, a printing process, a bag making process, or the like, a device for preventing this charging has been made. Examples of this include a method of kneading an antistatic agent in a resin before film production, and a method of coating an antistatic agent on the film surface.

上記のこれらの対策において、樹脂原料に帯電防止剤を練り込んでおく場合、条件によって帯電防止剤がフィルム表面にブリードするという問題がある。また、フィルム表面への帯電防止剤のコーティング方法では、フィルム製造においてこのコーティング費用が増加する。
本発明の目的は、上記二つの帯電防止性能付与以外の方法で、プラスチックフィルムに帯電防止性能を付与することにある。 In these countermeasures, when an antistatic agent is kneaded into the resin raw material, there is a problem that the antistatic agent bleeds on the film surface depending on conditions. Further, the coating cost of the antistatic agent on the film surface increases the coating cost in film production.
An object of the present invention is to impart antistatic performance to a plastic film by a method other than the above two methods of imparting antistatic performance.

上記目的を達成するため、本願発明者はプラスチックフィルムには印刷が施されていることが多いので、この印刷用インキであって、特に全面ベタ刷りを行なう裏刷り用のインキに帯電防止性能を付与しておけば、プラスチックフィルムに静電気が発生しても帯電を防止することができると考え、鋭意研究の結果、次に記述する発明を完成するに至ったのである。   In order to achieve the above object, the inventor of this application often prints on a plastic film. Therefore, this printing ink has an antistatic property, particularly for a back printing ink that performs a full solid printing. If it is given, it is thought that charging can be prevented even if static electricity is generated in the plastic film, and as a result of earnest research, the invention described below has been completed.

更に、請求項２に記載の発明においては、請求項１に記載の発明において、プラスチックフィルムは、透明または半透明であり、帯電防止性印刷インキは、裏刷り用のグラビアインキであることを特徴とするものである。   Furthermore, in the invention described in claim 2, in the invention described in claim 1, the plastic film is transparent or translucent, and the antistatic printing ink is a gravure ink for back printing. It is what.

更に、請求項３に記載の発明においては、請求項１または２に記載の発明において、帯電防止性印刷インキにおいて、ビヒクルバインダーの樹脂成分は、有機溶剤溶解型のエステル系ポリウレタン樹脂であることを特徴とするものである。   Further, in the invention described in claim 3, in the invention described in claim 1 or 2, in the antistatic printing ink, the resin component of the vehicle binder is an organic solvent-soluble ester polyurethane resin. It is a feature.

更に、請求項４に記載の発明においては、請求項３に記載の発明において、エステル系ポリウレタン樹脂は、有機溶剤系の高Ｔｇと低Ｔｇポリマーの混合組成物であることを特徴とするものである。   Further, in the invention described in claim 4, in the invention described in claim 3, the ester polyurethane resin is a mixed composition of organic solvent-based high Tg and low Tg polymer. is there.

更に、請求項５に記載の発明においては、請求項４に記載の発明における溶剤型複合エステル系ポリウレタン樹脂に添加する帯電防止剤は、有機溶剤溶液型の帯電防止剤が添加されていることを特徴とするものである。   Further, in the invention described in claim 5, the antistatic agent added to the solvent-type composite ester polyurethane resin in the invention described in claim 4 is that an organic solvent solution type antistatic agent is added. It is a feature.

更に、請求項６に記載の発明においては、請求項５に記載の帯電防止剤は、脂肪酸ジメチルエチルアンモニゥムエトサルフェートとポリオキシエチレンアルキルエーテルとの有機溶剤溶液の混合組成物であることを特徴とするものである。   Furthermore, in the invention described in claim 6, the antistatic agent described in claim 5 is a mixed composition of an organic solvent solution of fatty acid dimethyl ethyl ammonium sulfate and polyoxyethylene alkyl ether.

更に、請求項７に記載の発明においては、プラスチックフィルム印刷物において、有機溶剤系帯電防止性印刷インキを用いて裏刷りされたことを特徴とするものである。   Furthermore, the invention described in claim 7 is characterized in that a plastic film print is back printed using an organic solvent-based antistatic printing ink.

〔作用〕
上記構成において、帯電防止剤を添加したインキは、通常の印刷機を用い、従来通りの印刷方法で印刷することができる。この印刷は、裏刷りインキに帯電防止剤を添加しておくのが最も有効であるが、裏刷りインキ以外のインキであっても良い。ただし、帯電防止性能を有効に発揮するためには、全面またはこれに限りなく近い面積において帯電防止性能を有することが必要なため、裏刷りインキが最も有効である。印刷方法は、グラビア印刷以外にフレキソ印刷などにおいても利用が可能であり、印刷方法を問わない。 [Action]
In the above configuration, the ink to which the antistatic agent is added can be printed by a conventional printing method using a normal printing machine. In this printing, it is most effective to add an antistatic agent to the back printing ink, but an ink other than the back printing ink may be used. However, in order to effectively exhibit the antistatic performance, it is necessary to have the antistatic performance on the entire surface or an area close to it. Therefore, the back printing ink is most effective. The printing method can be used not only for gravure printing but also for flexographic printing, and any printing method can be used.

本発明は、印刷インキに帯電防止剤を添加したことにより、このインキを用いて、例えば裏刷りを行うことで、印刷と同時に、帯電防止性能をプラスチックフィルムに付与することができる。そして、この帯電防止剤は、インキに添加されており、特に裏刷りインキに用いることにより、従来の練り込み方式のようなブリードの問題が発生しないため、衛生上、あるいはプラスチックフィルムの品質の低下をもたらすこともない。
また、本願発明は、フィルムの表面に帯電防止剤をコーティングする従来方式に比較して、印刷と同時に帯電防止性能がフィルムに付与されることから、コーティング工程を省略することができ、帯電防止性能を有するプラスチックフィルム製品についてそのコストの低下を図ることが可能となる。 In the present invention, by adding an antistatic agent to the printing ink, by using this ink, for example, reverse printing, it is possible to impart antistatic performance to the plastic film simultaneously with printing. This antistatic agent is added to the ink, and particularly when used in the back printing ink, the problem of bleeding as in the conventional kneading method does not occur. Therefore, the quality of the plastic film is deteriorated. It will not bring
In addition, the present invention can eliminate the coating process since the antistatic performance is imparted to the film at the same time as printing compared to the conventional method in which an antistatic agent is coated on the surface of the film. It is possible to reduce the cost of the plastic film product having the above.

本発明は、有機溶剤系の帯電防止性印刷インキであって、たとえば裏刷り用印刷インキのビヒクルバインダーであり、本バインダーに例えば酸化チタンなどの顔料および溶剤を混合することにより、本発明の目的である有機溶剤系帯電防止性印刷インキを作成することができる。
そして、ビヒクルバインダーの樹脂成分は、有機溶剤溶解型のエステル系ポリウレタン樹脂であって、この樹脂は、有機溶剤系の高Ｔｇポリマーと低Ｔｇポリマーの混合組成物である。そして、高Ｔｇポリウレタン樹脂は、Ｔｇ＝０〜４０℃の範囲である。また、低Ｔｇポリウレタン樹脂は、Ｔｇ＝−３０〜０℃の範囲である。
上記高Ｔｇ樹脂と低Ｔｇ樹脂との混合比は、固形分重量比で１：５〜１：１であるが、好ましくは、１：２〜１：２．５の混合比である。 The present invention is an organic solvent-based antistatic printing ink, for example, a vehicle binder for printing ink for back printing, and the object of the present invention is to mix a pigment such as titanium oxide and a solvent with the binder. An organic solvent-based antistatic printing ink can be prepared.
The resin component of the vehicle binder is an organic solvent-soluble ester polyurethane resin, and this resin is a mixed composition of organic solvent-based high Tg polymer and low Tg polymer. And high Tg polyurethane resin is the range of Tg = 0-40 degreeC. The low Tg polyurethane resin has a range of Tg = -30 to 0 ° C.
The mixing ratio of the high Tg resin and the low Tg resin is 1: 5 to 1: 1 in terms of solid content weight ratio, and preferably 1: 2 to 1: 2.5.

本発明における帯電防止剤は、脂肪酸ジメチルエチルアンモニゥムエトサルフェートとポリオキシエチレンアルキルエーテルとの混合組成物であって、固形分重量比は８：１〜１５：１の範囲であるが、好ましくは１０：１〜１２：１の範囲である。   The antistatic agent in the present invention is a mixed composition of fatty acid dimethylethyl ammonium methosulfate and polyoxyethylene alkyl ether, and the solid content weight ratio is in the range of 8: 1 to 15: 1, preferably Is in the range of 10: 1 to 12: 1.
