Abstract
Description
しかし、この様なインクジェットインキを使用して印刷物を製造した場合、ポリ塩化ビニル系シートへの密着性は良好となるが、コックリング(基材がたわむ現象)が起こりやすくなるという問題を有している。
また、この光硬化型インクジェット印刷用インクの用途として屋外の大型宣伝広告以外に、屋外用シール用途での使用も要求され、光硬化型インクジェット印刷用インクを硬化して得られる硬化膜の延伸性も要求されるようになってきている。
この提案により、発光ダイオード光に対する硬化性や印刷性能は改善され良好となった。
また、上述の本発明者らが先に提案した光硬化型インクジェット印刷用インク組成物は、硬化後の硬化膜の延伸性について改善の余地を残すものであった。
また、本発明は、(3)アクリル化アミン化合物として、2個の光重合性官能基が(メタ)アクリロイル基であり、アミン価が130~142KOHmg/gである化合物を用いる上記(1)項又は(2)項に記載の光硬化型インクジェット印刷用インク組成物に関する。
また、本発明は、(4)更に、顔料を含有する上記(1)項、(2)項又は(3)項に記載の光硬化型インクジェット印刷用インク組成物に関する。
また、本発明は、(5)インクジェット印刷時の液温における粘度が20mPa・s以下である上記(1)項、(2)項、(3)項又は(4)項に記載の光硬化型インクジェット印刷用インク組成物に関する。
また、本発明は、(6)厚さ5μm、幅25mm、長さ50mmの硬化膜を形成したときに、該硬化膜の延性が200%以上である光硬化型インクジェット印刷用インク組成物に関する。
なお、本明細書において、上記硬化膜の延性とは、下記方法により測定される値を意味する。
光硬化型インクジェット印刷用インク組成物を用いて形成した厚さ5μ、幅25mm、長さ50mmの硬化膜を、引張試験機(安田精社製)を用いて、荷重範囲0~10kgf、引張速度30mm/minの条件で硬化膜の表面が断裂するまで、硬化膜の長さ方向に引張る。
そして、下記式により算出される値を延性とする。
(硬化膜の表面が断裂するまでの硬化膜の長さ/引張試験を行う前の長さ)×100(%)
以下、本発明の光硬化型インクジェット印刷用インク組成物及びそれを用いて得られる印刷物について具体的に説明する。
そして、本発明の光硬化型インクジェット印刷用インク組成物を構成する光重合性化合物として、ベンジルアクリレートを使用する。光硬化型インクジェット印刷用インク組成物で利用する従来の光重合性化合物において、粘度の低いものは総じて発光ダイオード光に対する硬化性が良好であるが、引火点が低いという傾向がある。このため、吐出性の向上を目的としてインク粘度を低下させるために、低粘度の光重合性化合物を利用すると、同時に引火点も低下してしまう場合が多い。これに対して、ベンジルアクリレートは、低粘度である割には引火点があまり低下しない。また、ベンジルアクリレートと分子内に2個の光重合性官能基及び2個のアミノ基を有するアクリル化アミン化合物を併用使用することで、発光ダイオード光に対する硬化性を良好に維持することができるという特徴を有する。
また、ベンジルアクリレートは、硬化膜の延伸性を良好にすることができる特徴を有する。この様な特徴から、本発明ではベンジルアクリレートを、分子内に2個の光重合性官能基及び2個のアミノ基を有するアクリル化アミン化合物と併用し、更に後述する他の光重合性化合物と併用することにより、引火点を低下させずある程度維持したまま粘度の低下を図ることができる。また、本発明は、発光ダイオード光に対する硬化性にも優れ、更に密着性、コックリング防止性にも優れ、得られる硬化膜の延伸性に優れるインク組成物とすることができたのである。
なお、本明細書において、(メタ)アクリロイル基とは、アクリロイル基又はメタクリロイル基を意味する。
上記2官能(メタ)アクリレートとしては、例えば、1,4-ブタンジオールジ(メタ)アクリレート、1,6-ヘキサンジオールジ(メタ)アクリレート、1,9-ノナンジオールジ(メタ)アクリレート、プロピレングリコールジ(メタ)アクリレート、1,3-ブチレングリコールジ(メタ)アクリレート、ネオペンチルグリコールジ(メタ)アクリレート等のアルキレングリコールジ(メタ)アクリレート;ビスフェノールAのエチレンオキサイド付加物のジ(メタ)アクリレート、ビスフェノールFのエチレンオキサイド付加物のジ(メタ)アクリレート、ビスフェノールSのエチレンオキサイド付加物のジ(メタ)アクリレート、チオビスフェノールのエチレンオキサイド付加物のジ(メタ)アクリレート、臭素化ビスフェノールAのエチレンオキサイド付加物のジ(メタ)アクリレート等のビスフェノールアルキレンオキシド付加物ジ(メタ)アクリレート;ポリエチレングリコールジ(メタ)アクリレート、ポリプロピレングリコールジ(メタ)アクリレート等のポリアルキレングリコールジ(メタ)アクリレート;ヒドロキシピバリン酸ネオペンチルグリコールエステルのジ(メタ)アクリレート;等が挙げられる。なかでも、1,6-ヘキサンジ(メタ)アクリレートが好ましい。
なお、本明細書において、(メタ)アクリレートとは、アクリレート又はメタクリレートを意味する。
また、本発明では、ベンジルアクリレートを使用するため、粘度が低くなりすぎ、タックが出てくる傾向となる。このため、イソボニルアクリレート及び/又はテトラヒドロフルフリルアクリレートを上記光硬化型インクジェット印刷用インク組成物中に5~40質量%含有させることが好ましい。上記含有量が5質量%未満であると、粘度低下、タックを充分に抑制できないことがあり、40質量%を超えると、密着性が低下する傾向にある。
なお、上記「400nm以上の波長の光により増感機能が発現する」とは、400nm以上の波長域で光吸収特性を有することをいう。このような増感剤を用いることで、本発明の光硬化型インクジェット印刷用インク組成物のLED硬化性を促進させることができる。
また、本発明の光硬化型インクジェット印刷用インク組成物には、必要に応じ着色剤を含有させることができる。上記着色剤としては、光硬化型インクジェット印刷用インク組成物において従来から使用されているものを特に制限なく使用できるが、インク組成物に良好に分散し、耐光性の優れた顔料が好適に用いられる。上記顔料としては、有機顔料又は無機顔料のいずれであってもよい。
無機顔料としては、カーボンブラック、酸化チタン、ベンガラ、黒鉛、鉄黒、酸化クロムグリーン、水酸化アルミニウム等が挙げられる。
顔料分散剤としては、従来から使用されているものを特に制限なく使用できるが、その中でも高分子分散剤を使用することが好ましい。このような顔料分散剤としては、カルボジイミド系分散剤、ポリエステルアミン系分散剤、脂肪酸アミン系分散剤、変性ポリアクリレート系分散剤、変性ポリウレタン系分散剤、多鎖型高分子非イオン系分散剤、高分子イオン活性剤等が挙げられる。これら顔料分散剤は単独で又は2種以上を混合して使用できる。
本明細書において、上記インクジェット印刷時の液温とは、以下の条件によるインク組成物の温度である。すなわち、本発明の光硬化型インクジェット印刷用インク組成物を使用して室温(25℃)でインクジェット印刷をする場合は、上記印刷時の液温とは室温である。一方、インクジェット印刷装置のインクタンクを加熱して、室温より高い温度で印刷する場合には、実際に印刷するときに加温されているインクタンクの温度である。
なお、上記印刷時の液温は、多くは室温であるが、60℃未満であることが好ましい。
上記インクジェット印刷時の液温における粘度とは、E型粘度計(商品名:RE100L型粘度計、東機産業社製)を用いて測定したものである。
本発明の光硬化型インクジェット印刷用インク組成物を印字する基材としては、ターポリンや塩化ビニル樹脂シート等のポリ塩化ビニル系シートが好ましいが、従来から紫外線インクジェット印刷用インク組成物に印字されている基材(紙、プラスチックフィルム、カプセル、ジェル、金属箔、ガラス、木材、布等)であれば問題なく印字できる。
例えば、基材への吐出(画像の印字)は、上記光硬化型インクジェット印刷用インク組成物をインクジェット記録方式用プリンター装置のプリンターヘッドに供給し、このプリンターヘッドから被記録材に塗膜の膜厚が1~20μmとなるように該インク組成物を吐出することにより行うことができる。光での露光、硬化(画像の硬化)は、画像として被記録材に塗布された該インク組成物に光を照射することにより行うことができる。
すなわち、本発明はまた、ポリ塩化ビニル系シートに、上記光硬化型インクジェット印刷用インク組成物を1~20μmの膜厚で印刷した後、光硬化して得られることを特徴とする印刷物である。
