Abstract
Description
本発明は、ラミネート用水性インキ組成物およびそれを用いた積層物に関し、より詳しくは、各種プラスチックフィルムに適用可能で、特にポリオレフィン系フィルムに対する接着性、溶融ポリプロピレンのダイレクトラミネート適性、サーマルラミネート適性に優れたラミネート用水性インキ組成物およびそれを用いた積層物に関する。 The present invention relates to a water-based ink composition for laminating and a laminate using the same. More specifically, the present invention can be applied to various plastic films, in particular, adhesion to polyolefin films, suitability for direct lamination of molten polypropylene, and suitability for thermal lamination. The present invention relates to an excellent water-based ink composition for laminating and a laminate using the same.
近年、被包装物の多様化、包装技術の高度化に伴ない、包装材料として各種のプラスチックフィルムが開発され、被包装物に適したものが適宜選択して使用されるようになってきている。またプラスチックフィルムを包装材料に使用するにあたってはプラスチックフィルムの装飾または表面保護のために印刷が施されるが、かかる印刷のための印刷インキには、これら種々のプラスチックフィルムに対する高度な性能、品質が要求されるようになってきている。とりわけ印刷インキに関しては包装容器の美粧化、高級化のために各種複合フィルムに対する幅広い接着性、さらにはラミネート加工適性、ボイル適性、レトルト適性等の各種後加工適性が必要になってきている。 In recent years, with the diversification of packaging materials and the advancement of packaging technology, various plastic films have been developed as packaging materials, and those suitable for packaging materials have been appropriately selected and used. . In addition, when plastic films are used for packaging materials, printing is performed for the decoration or surface protection of the plastic film. The printing ink for such printing has high performance and quality for these various plastic films. It is becoming required. In particular, printing inks are required to have various adhesive properties for various composite films and various post-processing aptitudes such as laminating suitability, boil suitability, and retort suitability in order to beautify and upgrade packaging containers.
また、包装材料の高性能化のため、印刷後にドライラミネート加工、エクストルージョンラミネート加工を施すことがある。この場合ドライラミネート加工にはウレタン系等の接着剤を使用し、エクストルージョンラミネート加工の場合はアンカーコート剤を使用する。さらに中間にアルミニウム箔を介在させることもあり、ボイル、レトルト加工が可能な包装材料とすることもある。またレトルト加工までの強度は要求されないが透明基材をベースとした包装材料分野においてはコロナ放電処理延伸ポリプロピレン(OPP)を基材フィルムとし、アンカーコート剤は用いずに、直接、溶融ポリプロピレンで被覆するラミネート加工方法(PPダイレクトラミネート)、溶融ポリマーを用いず、熱圧着により基材フィルムとシーラントフィルムとを直接ラミネートする加工方法(PPサーマルラミネート)も行われている。 Moreover, in order to improve the performance of packaging materials, dry lamination processing and extrusion lamination processing may be performed after printing. In this case, an adhesive such as urethane is used for the dry laminating process, and an anchor coat agent is used for the extrusion laminating process. Furthermore, an aluminum foil may be interposed in the middle, and the packaging material may be boiled or retort processed. Although strength is not required until retorting, in the packaging material field based on transparent substrates, corona discharge-treated expanded polypropylene (OPP) is used as the base film, and it is directly coated with molten polypropylene without using an anchor coat agent. A laminating method (PP direct laminating) and a laminating method (PP thermal laminating) in which a base film and a sealant film are directly laminated by thermocompression bonding without using a molten polymer are also performed.
かかる印刷後に加工を行うためには、その前段階で用いる印刷インキに対して、種々の基材フィルムに対する接着性、印刷適性はもとより、それぞれの後加工に対する適性を具備していることが要求される。PPダイレクトラミネート、PPサーマルラミネートが施されるポリオレフィンに対しては、塩素化ポリプロピレン等の高塩素化度の塩素化ポリオレフィンをバインダーとした溶剤型印刷インキがもっぱら使用されている。しかしながら、これら溶剤型インキではインキ中および希釈溶剤中に多量の有機溶剤を含有しているため、印刷作業環境中に溶剤蒸気が存在するようになり、作業者に対して健康上好ましくない影響を与えているばかりでなく、火災の危険性もあり好ましくない。また溶剤型インキを使用した場合、人体に有害な有機溶剤がラミネート物中に残留するため、食品包装に用いた場合には食品に残留溶剤が移行し易く、食品衛生上好ましくない。 In order to perform processing after such printing, it is required that the printing ink used in the previous stage has not only adhesiveness to various substrate films and printability but also suitability for each post-processing. The For polyolefins to which PP direct lamination and PP thermal lamination are applied, solvent-based printing inks using a chlorinated polyolefin having a high chlorination degree such as chlorinated polypropylene as a binder are exclusively used. However, since these solvent-based inks contain a large amount of organic solvent in the ink and the diluting solvent, solvent vapor is present in the printing work environment, which has an adverse effect on the health. Not only is it giving, but there is also a risk of fire, which is undesirable. In addition, when solvent-based ink is used, an organic solvent harmful to the human body remains in the laminate, and when used in food packaging, the residual solvent tends to migrate to food, which is not preferable for food hygiene.

さらに、特開平09−31386号公報には水性アクリル樹脂またはエチレンアクリル酸系樹脂が固形分で50〜95重量%、分子量2,000〜200、000のマレイン酸変性ポリプロピレンが5〜50重量%、その他の樹脂が0〜30重量%であることを特徴とする水性印刷インキ組成物が開示されている。 Furthermore, JP 09-31386 A discloses an aqueous acrylic resin or ethylene acrylic acid resin in a solid content of 50 to 95% by weight, a maleic acid-modified polypropylene having a molecular weight of 2,000 to 200,000, 5 to 50% by weight, An aqueous printing ink composition characterized in that the other resin is 0 to 30% by weight is disclosed.
しかしながら何れの発明も、基材密着性を塩素化ポリプロピレンやマレイン酸変性ポリプロピレンにのみ頼っているため、十分なラミネート強度を得ることが出来なかった。
この様な理由から、水性であって、かつ、幅広い種類のプラスチックフィルムに対する接着性、PPダイレクトラミネート適性、サーマルラミネート適性、印刷適性の良好な水性インキ組成物は未だ得られていないのが現状である。
However, in any of the inventions, since the substrate adhesion depends only on chlorinated polypropylene or maleic acid-modified polypropylene, sufficient laminate strength cannot be obtained.
For these reasons, water-based ink compositions that are water-based and have good adhesion to a wide variety of plastic films, PP direct laminate suitability, thermal laminate suitability, and printability have not yet been obtained. is there.

次に、本発明の水性バインダーに用いられる酸変性ポリプロピレン樹脂水分散体(A)について説明する。酸変性ポリプロピレン樹脂水分散体(A)とは、マレイン酸等の共役二重結合を有する二塩基酸で変性した変性ポリプロピレン系樹脂を、水中に分散せしめて得られるエマルジョンである。ポリプロピレンの数平均分子量としては、水性インキ組成物のプラスチックフィルムに対する接着性やダイレクトラミネート適性、耐ブロッキング性の低下を防ぐ観点から重量平均分子量は10000以上であることが必要であり、さらに好ましくは20000以上であることが望ましい。さらに、インキ組成物の経時安定性の観点からは200000以下であることが必要であり、さらに、好ましくは、100000以下であることが望ましい。 Next, the acid-modified polypropylene resin aqueous dispersion (A) used for the aqueous binder of the present invention will be described. The acid-modified polypropylene resin aqueous dispersion (A) is an emulsion obtained by dispersing a modified polypropylene resin modified with a dibasic acid having a conjugated double bond such as maleic acid in water.
