Abstract
Description
具体的には、従来知られる親水性基含有ポリウレタンとポリシロキサンとを水系媒体中にそれぞれ混合して得たインクジェット印刷インク用バインダーを検討した。
しかし、前記ポリシロキサンは、通常、単独で良好な水分散性を有さないため、前記インクジェット印刷インク用バインダーの凝集が生じやすく、インクジェットプリンターのインク吐出ノズルの詰まり等を引き起こし、その結果、印刷画像を形成できない場合があった。
そこで、前記ポリシロキサンの水分散性を向上することを検討し、前記ポリウレタンとポリシロキサンとを、乳化剤を用いて水系媒体中に分散して得られたインクジェット印刷インク用バインダーを検討した。
前記バインダーを用いて得たインクであれば、ある程度鮮明な印刷画像を形成することができたものの、前記乳化剤の印刷画像表面へのブリード等に起因した印刷画像の色落ちが生じるなど、依然として十分な耐擦過性を有するとはいいがたいものであった。
また、前記ポリシロキサンとして、例えば親水性基とポリシロキサン構造とを有する樹脂を前記親水性基含有ポリウレタンと組み合わせ使用したインクジェット印刷インク用バインダーを検討した。
しかし、前記バインダーを用いて得たインクは、通常のインクジェットプリンターに備えられているインク吐出ノズルから吐出しにくいため、インクジェット印刷用インクとして使用することが困難であった。
そこで、本発明者等は、ポリシロキサンを、親水性基含有ポリウレタンを用いて水系媒体中に安定分散させる手法を検討し、前記ポリシロキサン(A)が親水性基含有ポリウレタン(B)によって水系媒体(C)中に分散されたバインダーを用いて得たインクであれば、インク吐出ノズルの詰まりを引き起こしにくく、保存安定性に優れ、かつ、高鮮明で耐擦過性に優れた印刷画像を形成できることを見出し、上記課題を解決するに至った。
また、本発明は、前記インクジェット印刷インク用バインダーと、顔料とを含有するインクジェット印刷用インク、及びそれを用いて印刷の施された印刷物に関する。

水系媒体(C)は、前記ポリシロキサン(A)と親水性基含有ポリウレタン(B)の溶媒に使用する。前記水系媒体(C)としては、水、水と混和する有機溶剤、及び、これらの混合物が挙げられる。水と混和する有機溶剤としては、例えば、メタノール、エタノール、n-及びイソプロパノール等のアルコール類;アセトン、メチルエチルケトン等のケトン類;エチレングリコール、ジエチレングリコール、プロピレングリコール等のポリアルキレングリコール類;ポリアルキレングリコールのアルキルエーテル類;N-メチル-2-ピロリドン等のラクタム類、等が挙げられる。本発明では、水のみを用いても良く、また水及び水と混和する有機溶剤との混合物を用いても良く、水と混和する有機溶剤のみを用いても良い。安全性や環境に対する負荷の点から、水のみ、又は、水及び水と混和する有機溶剤との混合物が好ましく、水のみが特に好ましい。
前記水系媒体(C)は、前記インクジェット印刷インク用バインダーの全量に対して、50~90質量%含まれることが好ましく、60~85質量%含まれることがより好ましい。
本発明のインクジェット印刷用インクは、前記インクジェット印刷インク用バインダー、顔料や染料、その他必要に応じて各種の添加剤を含有するものである。
前記無機顔料としては、例えば酸化チタン、アンチモンレッド、ベンガラ、カドミウムレッド、カドミウムイエロー、コバルトブルー、紺青、群青、カーボンブラック、黒鉛等を使用することができる。
