Definitions
- the present invention relates to a maintenance liquid for inkjet recording, an ink set for inkjet recording, an image forming method, and a maintenance method.
- Recording methods using the ink jet method are widely used because, for example, high-quality images can be recorded on a wide variety of recording media by ejecting ink in droplets from a large number of nozzle holes provided in an ink jet head. It's being used.
- a pigment is widely used for a colorant that is one of the components contained in an ink, and the pigment is used by being dispersed in a medium such as water.
- Pigment inks containing pigments tend to thicken and gradually solidify as the solvent component in the ink evaporates. Once the pigment ink is solidified, it is difficult to be redissolved thereafter. For this reason, as the ink thickens and solidifies, it gradually accumulates at the nozzle tip of the ink jet head, resulting in narrowing or clogging of the nozzle holes, resulting in bending of the ink ejection direction or failure. This may cause problems such as causing discharge. As the ink adheres and accumulates, it becomes difficult to maintain the performance by the nozzle cap, the wipe part, and the like, and the image formability with time deteriorates.
- the ink is more likely to be solidified and deposited as described above.
- a cleaning liquid for cleaning ink.

Abstract
Description
顔料を含有する顔料インクは、インク中の溶剤成分が蒸発するに伴って増粘しやすく、次第に固化する。顔料インクは、固化してしまうとその後に再溶解し難い。そのため、インクの増粘及び固化が進行すると、インクジェットヘッドのノズル先端部等に徐々に堆積し、結果的にノズルの孔を狭めたり目詰まりを来たし、ひいてはインクの吐出方向が曲がったり、あるいは不吐出を引き起こす等の支障を来たす。インクが付着し堆積していくにつれ、ノズルキャップやワイプ部等による性能維持が困難になり、経時での画像形成性は悪化する。

本発明のインクジェット記録用メンテナンス液は、少なくとも、以下に示す一般式(I)で表される化合物と、以下に示す一般式(II)で表される水溶性有機溶剤と、保湿剤と、水とを含有する。本発明のインクジェット記録用メンテナンス液は、必要に応じて、更に、有機溶剤、塩基性化合物、その他添加剤等を含有してもよい。
本発明においては、特定範囲のHLB値と特定の構造を有する界面活性剤と、アルキレンオキシ基を持つ特定構造の水溶性有機溶剤とを含有することで、従来の洗浄液に比べて、インク固形物の溶解性が高められ、優れた洗浄性を発揮する。例えばミスト状の微粒のインクが乾燥固化することでインクが粒状の固化物としてヘッド上に在る場合でも、洗浄後に拭き取る等の過程で吐出孔を閉塞したり、孔付近に堆積する等に伴って生じる、インクの吐出曲がりや不吐出等の吐出不良が防止される。これにより、長期に亘り安定した画像形成性を保持することができる。

一般式(II)で表される水溶性有機溶剤のインクジェット記録用メンテナンス液中における含有量としては、0.3~20質量%が好ましく、1~10質量%がより好ましい。添加量が0.2質量%未満ではインク固形物の溶解性の向上効果が小さくなり、20質量%を超えるとインク混合時に凝集し易くなり好ましくない。
また、SP値は、インク固形物の溶解性の向上の観点から、24以下が好ましく、22以下が更に好ましい。
これら水溶性有機溶剤は、1種単独であるいは複数を組み合わせて用いてもよい。
本発明のインクジェット記録用メンテナンス液は、保湿剤の少なくとも一種を含有することが好ましい。保湿剤を含有することで、メンテナンス液の水分蒸発による乾燥を抑制し、長期放置時のメンテナンス液の組成の変質を抑制することができる。

本発明におけるインク組成物は、ポリマー粒子の少なくとも一種を含有する。水に対して非水溶性又は難水溶性のポリマー粒子を、顔料を被う上記樹脂とは別に含有することによって、インク組成物の記録媒体への定着性、及び形成画像の耐擦過性がより向上する。その一方、インクの吐出ヘッドへの付着、堆積が起きやすくなるが、本発明のインクセットは既述のメンテナンス液を用いて構成されるので、長期に亘りインクの吐出曲がりや不吐出等の吐出不良の発生を抑え、良好な画像形成性を保持することができる。
ここで分散状態とは、水性媒体中に水不溶性ポリマーが液体状態で分散された乳化状態(エマルション)、及び、水性媒体中に水不溶性ポリマーが固体状態で分散された分散状態(サスペンジョン)の両方の状態を含むものである。
自己分散性樹脂においては、インク組成物に含有されたときのインク定着性の観点から、水不溶性ポリマーが固体状態で分散された分散状態となりうる自己分散性樹脂であることが好ましい。
遠心分離前の固形分濃度に対する遠心分離後の固形分濃度の比が大きければ(1に近い数値であれば)、遠心分離によるポリマー粒子の沈降が生じない、すなわち、ポリマー粒子の水性分散物がより安定であることを意味する。本発明においては、遠心分離前後での固形分濃度の比が0.8以上であることが好ましく、0.9以上であることがより好ましく、0.95以上であることが特に好ましい。
ここで水溶性成分とは、自己分散性樹脂に含有される化合物であって、自己分散性樹脂を分散状態にした場合に水に溶解する化合物をいう。上記水溶性成分は自己分散性樹脂を製造する際に、副生又は混入する水溶性の化合物である。

なお、「(メタ)アクリレート」は、アクリレート又はメタクリレートを意味する。
脂環式(メタ)アクリレートとは、(メタ)アクリル酸に由来する構造部位と、アルコールに由来する構造部位とを含み、アルコールに由来する構造部位に、無置換又は置換された脂環式炭化水素基(環状脂肪族基)を少なくとも1つ含む構造を有しているものである。なお、上記脂環式炭化水素基は、アルコールに由来する構造部位そのものであっても、連結基を介してアルコールに由来する構造部位に結合していてもよい。
単環式(メタ)アクリレートとしては、シクロプロピル(メタ)アクリレート、シクロブチル(メタ)アクリレート、シクロペンチル(メタ)アクリレート、シクロヘキシル(メタ)アクリレート、シクロヘプチル(メタ)アクリレート、シクロオクチル(メタ)アクリレート、シクロノニル(メタ)アクリレート、シクロデシル(メタ)アクリレート等のシクロアルキル基の炭素数が3~10のシクロアルキル(メタ)アクリレート等が挙げられる。2環式(メタ)アクリレートとしては、イソボルニル(メタ)アクリレート、ノルボルニル(メタ)アクリレート等が挙げられる。3環式(メタ)アクリレートとしては、アダマンチル(メタ)アクリレート、ジシクロペンタニル(メタ)アクリレート、ジシクロペンテニルオキシエチル(メタ)アクリレート等が挙げられる。これらは、それぞれ単独で又は2種以上を混合して用いることができる。
自己分散状態の安定性、芳香環同士の疎水性相互作用による水性媒体中での粒子形状の安定化、粒子の適度な疎水化による水溶性成分量の低下の観点から、15~90質量%であることがより好ましく、15~80質量%であることがより好ましく、25~70質量%であることが特に好ましい。

本発明におけるインク組成物は、水を用いて構成することができる。水の量には、特に制限はないが、安定性及び吐出信頼性の確保の点で、好ましくは10質量%以上99質量%以下である。
本発明のインク組成物は、尿素又はその誘導体を含有することが好ましい。尿素及びその誘導体によれば、顔料を含むインク組成物が付着した場合のワイピング等によるクリーニング性が向上する。特に上記ポリマー粒子を含有する場合に、乾燥固化したときの拭き取り性(ワイピング性)が改善される。
尿素及びその誘導体の含有量が1.0質量%以上であると、インクが付着した場合により拭き取り易くなり、メンテナンス性が向上する。また、尿素及びその誘導体の含有量が20.0質量%以下であると、画像中に含まれる尿素及びその誘導体の吸湿によるベタツキ防止、ブロッキング防止の点で有利である。
本発明におけるインク組成物は、上記成分のほか、必要に応じて、その他の成分を含むことができる。その他の成分としては、例えば、界面活性剤、紫外線吸収剤、褪色防止剤、防黴剤、pH調整剤、防錆剤、酸化防止剤、乳化安定剤、防腐剤、消泡剤、粘度調整剤、分散安定剤、キレート剤等の公知の添加剤が挙げられる。

本発明におけるインク付与工程は、インク組成物をインクジェット記録用ヘッドから吐出することで、インク組成物を記録媒体に付与し、記録媒体上に画像形成する。本工程では、記録媒体上にインク組成物を付与でき、所望の可視画像を形成できる。なお、インク組成物の詳細については既述の通りである。
なお、上記インクジェット法には、フォトインクと称する濃度の低いインクを小さい体積で多数射出する方式、実質的に同じ色相で濃度の異なる複数のインクを用いて画質を改良する方式や無色透明のインクを用いる方式が含まれる。
本発明の画像形成方法は、これらのいずれにも適用可能であるが、一般にダミージェットを行なわないライン方式に適用した場合に、吐出精度及び画像の耐擦過性の向上効果が大きい。
なお、インク滴の液滴量は、打滴するインク組成物に応じて、インクジェット法における吐出条件を適宜選択することで調整することができる。
本発明におけるインク除去工程は、上記インク付与工程でインク組成物を吐出することにより、インクジェット記録用ヘッドに付着したインク組成物(例えば、乾燥により固形化したインク固形物)をインクジェット記録用メンテナンス液により除去する。本工程で用いるメンテナンス液の構成及び好ましい態様等の詳細については、既述した通りである。
本発明における処理液付与工程は、インク組成物中の成分を凝集させる凝集成分を含有する処理液を記録媒体に付与する。記録媒体上でインク組成物と凝集成分とが混合することで、インク組成物中で安定的に分散している顔料等の凝集が促進される。

-水不溶性ポリマー分散剤P-1の合成-
以下に示すようにして水不溶性ポリマー分散剤P-1を合成した。
攪拌機、冷却管を備えた1000mlの三口フラスコに、メチルエチルケトン88gを加えて窒素雰囲気下で72℃に加熱し、ここに、メチルエチルケトン50gにジメチル2,2’-アゾビスイソブチレート0.85g、ベンジルメタクリレート60g、メタクリル酸10g、及びメチルメタクリレート30gを溶解させた溶液を3時間かけて滴下した。滴下終了後、更に1時間反応させた後、メチルエチルケトン2gにジメチル2,2’-アゾビスイソブチレート0.42gを溶解させた溶液を加え、78℃に昇温して4時間加熱した。得られた反応溶液を大過剰量のヘキサンに2回再沈殿させ、析出した樹脂を乾燥した。このようにして、ベンジルメタクリレート/メタクリル酸/メチルメタクリレート共重合体(=60/10/30[質量比])である水不溶性ポリマー分散剤P-1を96g得た(下記式参照)。
得られた共重合体の組成は、1H-NMRで確認し、GPCによりポリスチレン換算で求めた重量平均分子量(Mw)は44,600であった。さらに、JIS規格(JISK0070:1992)に記載の方法により酸価を求めたところ、65.2mgKOH/gであった。
カーボンブラック(NIPEX160-IQ、デグッサ社製)10部と、上記のようにして得た水不溶性ポリマー分散剤P-1 3部と、メチルエチルケトン42部と、1NのNaOH水溶液5.5部と、イオン交換水87.2部とを混合し、ビーズミルにより0.1mmφジルコニアビーズを用いて、2500rpmで6時間分散した。得られた顔料分散液をメチルエチルケトンが充分に留去できるまで、55℃で減圧濃縮し、更に一部の水を除去した後、高速遠心冷却機7550(久保田製作所社製)を用いて、8000rpmで30分間遠心処理(50mL遠心菅を使用)を行ない、沈殿物を除去し、上澄み液を回収した。このようにして、樹脂被覆顔料粒子(水不溶性ポリマー分散剤で被覆された顔料)の顔料分散液Kを得た。
上澄み液の吸光度スペクトルを測定し、そこから顔料濃度を求めたところ、10.2質量%であった。また、顔料分散液K中に分散されている顔料粒子の平均粒径は、130nmであった。
攪拌機、温度計、還流冷却管、及び窒素ガス導入管を備えた2リットル三口フラスコに、メチルエチルケトン560.0gを仕込んで、87℃まで昇温した。反応容器内を、還流状態を保ちながら(以下、反応終了まで還流)、メチルメタクリレート278.4g、イソボルニルメタクリレート243.6g、メタクリル酸58.0g、メチルエチルケトン108g、及び「V-601」(和光純薬工業(株)製)2.32gからなる混合溶液を、2時間で滴下が完了するように等速で滴下した。そして、滴下完了後、1時間攪拌した。その後、「V-601」1.16gと、メチルエチルケトン6.4gとからなる溶液を加え、2時間攪拌を行なった(工程(1))。続いて、工程(1)を4回繰り返し、更に「V-601」1.16gと、メチルエチルケトン6.4gとからなる溶液を加えて3時間攪拌を続けた。重合反応終了後、溶液の温度を65℃に降温し、イソプロパノール163.0gを加えて放冷した。このようにして、メチルメタクリレート/イソボルニルメタクリレート/メタクリル酸共重合体(=48/42/10[質量比])の溶液を得た。
得られた共重合体の重量平均分子量(Mw)は63,000(GPCによりポリスチレン換算で算出)、酸価は65.1mgKOH/g((JISK0070:1992)に記載の方法により算出)であった。
その後、減圧下、反応容器内温度70℃で1.5時間保って、イソプロパノール、メチルエチルケトン、蒸留水を合計で287.0g留去した(溶剤除去工程)後、プロキセルGXL(S)(アーチ・ケミカルズ・ジャパン(株)製)0.278g(ポリマー固形分に対してベンゾイソチアゾリン-3-オンとして440ppm)を添加した。その後、1μmのフィルターでろ過を行ない、ろ過液を回収し、固形分濃度26.5%の自己分散性ポリマー粒子B-01の水性分散物を得た。
得られた自己分散性ポリマー粒子B-01の水性分散物をイオン交換水で希釈し、25.0%の分散液を調製し、下記の方法にて体積平均粒径を測定したところ、3.0nmであった。
得られた自己分散性ポリマー粒子の水性分散物を測定に適した濃度(ローディングインデックスが0.1~10の範囲)に適宜希釈した後、超微粒子粒度分布測定装置ナノトラックUPA-EX150(日機装(株)製)を用い、動的光散乱法により、各水分散物を全て同一測定条件にて体積平均粒子径を測定した。すなわち、粒子透過性:透過、粒子屈折率:1.51、粒子形状:非球形、密度:1.2g/cm3、溶剤:水、セル温度:18~25℃の条件において測定を行なった。
上記で得られた顔料分散液K、水不溶性ポリマー分散剤P-1、及び自己分散性ポリマー粒子B-01を用いて、下記のインク組成になるように各成分を混合した。これをプラスチック製のディスポーザブルシリンジに詰め、ポリフッ化ビニリデン(PVDF)製の孔径1μmフィルター(Millex-SV、直径25mm、ミリポア社製)で濾過し、ブラックインク(インク組成物)K-01を得た。

得られたメンテナンス液について、下記の評価を行なった。評価結果は、下記表1に示す。
パーフルオロデシルトリクロロシラン(FDTS)を付与して撥水性を持たせたインクジェット記録用ヘッド表面に、強制的に上記ブラックインクをスプレーで吹き付け、室温で1時間乾燥させた。ヘッド面上の乾燥した固形物をマイクロスコープで観察、記録し、インクの直径を求めた。その後、特開2011-73295号公報に記載の、洗浄液の液柱(洗浄液のコート層)を発生させるメンテナンス液(洗浄液)塗布ユニットを用意し、その上にメンテナンス液柱を形成した。このメンテナンス液柱に吐出ヘッドを60mm/秒の速度で通過させ、ヘッド表面にメンテナンス液を付着させた。このヘッド表面におけるインク固形物の残り具合をマイクロスコープで観察し、洗浄前の上記直径の各インクが洗浄後に溶解して消失したかどうかに基づいてインク固形物の溶解性を評価した。
通常はヘッドにメンテナンス液を付着させた後、布等で拭き取るが、解け残ったインクが存在すると、拭き取る際にインク吐出孔に移動し、吐出孔を閉塞したり、孔付近に堆積する等して吐出不安定化の要因になるため、拭き取らずに以下の評価基準にしたがってインク固形物の溶解性を評価した。
<評価基準>
A:直径12μm以下のインク固形物を完全に溶解する。
B:直径10μm以下のインク固形物を完全に溶解する。
C:直径 7μm以下のインク固形物を完全に溶解する。
D:直径 7μm以下のインク固形物が溶け残り、実用上支障を来たす可能性がある。
E:直径 5μm未満のインク固形物が溶け残り、実用上問題となる。
各メンテナンス液と上記ブラックインクとを7:3の重量比率で混合し、混合直後及び30℃環境下に7日間放置した後のインク混合液について、体積平均粒径を測定し、その差(Δ)を下記式により求め、凝集性を評価した。Δが大きいほど経時で凝集が進んでいることを意味し、好ましくない。下記の評価基準において、A~Cは実用上問題がなく、Dは吐出不良の可能性があり、Eは吐出不良となる可能性が高い。
なお、体積平均粒径の測定は、上記自己分散性ポリマー粒子B-01における測定と同様の方法にて行なった。
体積平均粒径の差(Δ) =(30℃環境下に7日間放置後の体積平均粒径)-(混合直後の体積平均粒径)
<評価基準>
A:Δ≦5nm
B:5<Δ≦10nm
C:10<Δ≦20nm
D:20<Δ≦50nm

<評価基準>
A:完全に水に溶解する。
B:極僅かに水不溶解物が発生。
C:いくらか水不溶解物が見られるが実用上問題ないレベル。
D:水不溶解物が見られ、乾燥時に不吐出の原因になる可能性がある。
E:水不溶解物が多く、実用上問題になる可能性が高い。
HLB値が10.5~13.8の一般式(I)で表される化合物の中でも、R1がオクチル基又はデシル基の化合物がより好ましく、特にR1がデシル基の化合物で、より好ましい結果が得られた。
また、HLB値が10.5~13.8の一般式(I)で表される化合物の中でも、R1の炭素数が小さいとインク固形物の溶解性が低下し、逆にR1の炭素数が大きいとインク混合液の凝集性及びインク混合液の乾燥時の水溶解性に低下する傾向が見られた。

A.画像形成
図1に示すインクジェット記録装置を用意し、4色の上記着色インクを以下のように吐出することによりインク画像を形成した。記録媒体としては、坪量104~154g/m2のOKトップコート+(王子製紙(株)製)を用いた。また、画像形成条件は、解像度:1200dpi(dot per inch)×1200dpi、吐出液滴量:3pL相当とした。
なお、図1において、1は、インクジェット記録装置であり、10は給紙部であり、12は処理液付与部であり、14は描画部であり、16は乾燥部であり、18は定着部であり、20は排出部であり、22は記録媒体であり、24は第1の中間搬送部であり、26は第2の中間搬送部であり、28は第3の中間搬送部であり、30は中間搬送体であり、32は搬送ガイドであり、50はフィーダーボードであり、52は給紙胴であり、70は描画ドラムであり、72C,72M,72Y,72Kはそれぞれインクヘッドであり、76は乾燥ドラムであり、84は定着ドラムであり、86は第1定着ローラであり、88は第2定着ローラであり、90はインラインセンサーであり、92は排紙台であり、94はチェーンデリバリーのスプロケットであり、96はチェーンデリバリーのチェーンであり、98は装置の外カバーである。
インクジェット記録装置を起動し、給紙部10から繰り出された記録媒体22に対して、処理液ドラム54(直径450mm)上で、処理液塗布装置56によって処理液を全面に薄膜塗布(2μm厚)した。このとき、処理液塗布装置56としてグラビアローラを使用した。
次いで、処理液を塗布した記録媒体22を温風噴出しノズル58(70℃温風(9m3/分)の吹き付け)とIRヒータ60(180℃)によって乾燥処理し、処理液中の溶剤の一部を乾燥させた。
この記録媒体22を第1の中間搬送部24を介して描画部14に搬送し、各色ベタ画像用の画像信号に応じて、CMY(シアン・マゼンダ・イエロー)のそれぞれの着色インクを吐出ヘッド72Y、72M、72Cからそれぞれ吐出し、記録媒体上に画像様に打滴した。インク吐出体積は、ハイライト部では1.4pl、高濃度部では3pl(2drops)とし、記録密度は主走査・副走査方向共に1200dpiで記録されるようにした。その際、不吐出ノズルが発生した場合は、不吐出ノズルの隣接ノズルから5pl(3drops)を吐出できるようにし、不吐出によるスジムラを見え難くする処理を行なった。また、処理液ドラム54、乾燥ドラム76を描画ドラム70と別に設けたことにより、処理液の乾燥を高速で行なう場合にも、その熱や風の悪影響が描画部に及ぶ事が無く、安定吐出が達成された。
次いで、乾燥ドラム76上では、第1のIRヒータ78(表面温度180℃)、温風噴出しノズル80(70℃温風(12m3/分)の風量)、及び第2のIRヒータ82(表面温度180℃)により乾燥させた。乾燥時間は、約2秒である。
次に、画像が形成された記録媒体22を、50℃の定着ドラム84と、80℃の第1定着ローラ86及び第2定着ローラ88とによって、0.30MPaのニップ圧で加熱定着した。このとき、第1定着ローラ86、第2定着ローラ88としては、金属製の心金に硬度30°のシリコーンゴムを6mmの厚さで設け、その上にソフトPFA被覆(50μm
厚)を施し、インク画像に対する密着性及び剥離性に優れたものを使用した。
記録媒体22は、各ドラム54、70、76、84によるドラム搬送によって535mm/sの搬送速度で搬送されるようにした。
以上の工程を経て、画像形成された記録媒体の評価サンプルを得た。
得られたメンテナンス液を用い、下記のメンテナンス性の評価を行なった。評価結果を下記表4に示す。
上記のように画像形成するに際して、吐出等を下記(ア)~(ウ)の条件で行ない、その後の再吐出性を評価し、メンテナンス性の合否を判定した。合否判定の結果から、下記評価基準にしたがってメンテナンス性を評価した。

(ア)インクを45分連続吐出し、吐出終了直後にメンテナンス液を吐出ヘッドのノズル面に付与してワイピングを1回実施し、その後のインク吐出率が90%以上の場合、合格とした。
(イ)インクを5分連続吐出し、吐出後30分休止し、休止後にメンテナンス液を吐出ヘッドのノズル面に付与してワイピングを1回実施し、その後のインク吐出率が90%以上の場合、合格とした。
(ウ)インクの5分連続吐出し、吐出終了直後にメンテナンス液をヘッドのノズル面に付与してワイピングを1回実施し、その後45分放置後、インク吐出率が90%以上の場合、合格とした。
~インク吐出率の測定~
インク吐出開始時に全ノズルからインクを吐出していることを確認し、ワイピング後の吐出ノズル数をカウントして、下記式から吐出率を算出した。
吐出率(%)=(ワイピング後の吐出ノズル数)/(全ノズル数)×100
<評価基準>
A:上記ア~ウの3項目とも合格
B:上記ア~ウの2項目が合格
C:上記ア~ウの1項目のみが合格
D:上記ア~ウの3項目とも不合格
実施例4の「No.48」のメンテナンス液の調製において、No.48組成中のイミダゾールを取り除いたこと以外は、No.48と同様にしてメンテナンス液を調製した。
このpH低下は、上記一般式(I)で表される化合物(界面活性剤)を添加すると大きくなっており、イミダゾール添加によりメンテナンス性の悪化を防いでいることが確認された。
実施例4の「No.48」のメンテナンス液の調製において、消泡剤として、BYK-012、017、021、022、024、025、038、094(ビックケミー・ジャパン(株)製)、KS-537、KS-604、KM-72F(信越化学工業(株)製)、TSA-739(モメンティブ・パフォーマンス・マテリアルズ・ジャパン合同会社製)、オルフィンAF104(日信化学工業(株)製)をそれぞれ0.01質量%添加して、メンテナンス性、及びメンテナンス後のスジ発生頻度について評価した。
本明細書に記載された全ての文献、特許出願、および技術規格は、個々の文献、特許出願、および技術規格が参照により取り込まれることが具体的かつ個々に記された場合と同程度に、本明細書中に参照により取り込まれる。
