なお、これらのベンゼン環において、トリアリールメチン構造の中央に位置する炭素原子との結合に対し、o-位にあまり嵩高い基が結合すると、後述するように分子の平面性が阻害され、化合物の色純度が低下する傾向がある。従って、o-位には置換基を有さないか、またはハロゲン原子、炭素数1~4のアルキル基などで置換されていることが好ましい。

この「任意の基」の例としては、Rがアルキル基またはフェニル基である場合に有していてもよい置換基として例示した前記置換基群Wが挙げられ、好ましい基も前述したものと同様である。なお、フタロシアニン骨格における各ベンゼン環は、無置換であるか、-SO3 -基以外に置換基を有さない場合が特に好ましい。
この範囲よりも一般式(V)で表される化合物の含有量が多いと塗膜の硬化性が低下し、膜強度が不充分になる可能性があり、少ないと着色力が不充分となり、充分な濃度の色度が得られないか、膜厚が厚くなりすぎる場合がある。
なお、前記一般式(V)で表される化合物の、着色樹脂組成物(特に該組成物中に含まれる溶剤)への溶解性が低い場合には、後述する任意成分である顔料と同様に、分散剤などを使用して組成物中へ分散させて使用してもよい。しかし、液晶表示装置に適用した場合のコントラストの高さ等の点からは、前記一般式(V)で表される化合物は、着色樹脂組成物中に溶解した状態で存在することが好ましい。
本発明の第3の態様に係る(c)色材は、カチオン系青色色素(色素1)とアニオン系色素(色素2)からなる化合物(色素1-色素2化合物)を含有し、この色素1-色素2化合物における色素1および色素2が以下の(イ)または(ロ)を満たすものであり、耐光性の高い画素を形成し得るカラーフィルター用着色樹脂組成物を提供する。
なお、色素1と色素2とからなる化合物の形態はカチオン系化合物である色素1とアニオン系化合物である色素2からなる塩である。また、色素1-色素2化合物を構成する色素1および色素2の数には特に制限はない。
(ロ)色素2が奇数電子系化合物であり、時間依存密度汎関数(B3LYP/6-31G(d,p))計算により得られる、色素1の最低一重項励起状態(S1状態)の励起エネルギー(ΔES1(色素1))と、色素2のエネルギー的に最も低い励起状態の励起エネルギー(ΔElowest(色素2))が、下記式(iii)を満たす。
なお本発明において、色素のエネルギー準位は、分子構造の構造最適を行った後、B3LYP/6-31G、TDDF計算により求めることができる。
この第3の態様における関係を満たす組み合わせの色素よりなる化合物で、このような効果が得られることの理由の詳細は明らかではないが、次のように推定される。
計算によるアニオンの最低三重項励起状態(T1状態)への励起エネルギーが式(ii)を満たすことは、アニオンのT1状態が酸素の1Δg状態への励起エネルギーより小さいことに対応しており、アニオンの最低三重項励起状態からの基底状態の酸素へのエネルギー移動が起こらないことになり、一重項酸素(1Δg状態の酸素)の生成が抑制される点で好ましい。
系中の一重項酸素(1Δg状態の酸素)は活性酸素の一種であり、色素1-色素2化合物を攻撃し結果的に色素1-色素2化合物が破壊されると考えられるが、本発明では色素1-色素2化合物の構造を工夫することにより、一重項酸素(1Δg状態の酸素)の発生を防ぎ、組成物の耐光性を向上させた。
また、色素2としては、アニオン性置換基を有するアニオン性色素が好ましい。
なお、本発明において、カチオン性色素とは、分子全体が正に荷電している色素を意味し、アニオン性色素とは、分子全体が負に荷電している色素を意味する。
また、このようなカチオン性色素と塩を形成するアニオン性色素としては、カチオン性色素のLUMOよりも低いLUMOを有し、かつ、カチオン性色素の一重項エネルギーのバンドギャップより、狭いバンドギャップを有するものを組み合わせることが好ましい。なお、カチオン色素よりも長波長領域に吸収を有し、スルホ基などの酸性度の高い置換基を有するアニオン色素であることが望ましい。
リールメチン系、キサンテン系など骨格内にカチオンを有するものや、アンモニウムカチオンを置換基として有するアントラキノン系、インジゴ系、フタロシアニン系、アゾ系などの中性色素が挙げられる。中でも分子吸光度の大きさから、骨格内にカチオンを有するものが好ましく、溶解性の観点から放射状の分子構造をしている化合物が好ましい。具体的には、トリアリールメチン系色素がより好ましい。

本発明の着色樹脂組成物は、耐熱性を向上させるため等の目的で、本発明の効果を損なわない範囲で(f)顔料を含有していてもよい。
尚、これらの顔料は、着色樹脂組成物中の平均粒径が通常1μm以下、好ましくは0.5μm以下、更に好ましくは0.3μm以下となるよう分散処理して使用する。
本発明の着色樹脂組成物は、前記各成分の外に、界面活性剤、有機カルボン酸および/または有機カルボン酸無水物、可塑剤、前記本発明に係る前述の(c)色材以外の染料、熱重合防止剤、保存安定剤、表面保護剤、密着向上剤、現像改良剤等を含有していてもよい。また、着色剤として(f)顔料を含有する場合には、分散剤や分散助剤を含有してもよい。これら任意成分としては、例えば特開2007-113000号公報記載の各種化合物を使用することができる。
次に、本発明の着色樹脂組成物を調製する方法を説明する。
先ず前述の本発明に係る(c)色材を、必須成分である(a)バインダー樹脂、および(b)溶剤、場合によっては、任意成分である(d)モノマーや(e)光重合開始系および/または熱重合開始系、界面活性剤、およびそれら以外の成分と混合し、均一な溶液とすることにより、着色樹脂組成物を得る。混合に際しては、(c)色材が十分に溶解するまで撹拌することが好ましい。また、混合等の各工程において、微細なゴミが混入することがあるため、得られたインキ状液体をフィルター等によって濾過処理することが好ましい。
本発明の着色樹脂組成物は、通常、すべての構成成分が溶剤中に溶解或いは分散された状態である。このような着色樹脂組成物が基板上へ供給され、カラーフィルターや液晶表示装置、有機ELディスプレイなどの構成部材が形成される。
以下、本発明の着色樹脂組成物の応用例として、カラーフィルターの画素としての応用、およびそれらを用いた液晶表示装置(パネル)および有機ELディスプレイについて、説明する。
カラーフィルターの画素は、後述するように様々な方法で形成することができる。ここでは光重合性の着色樹脂組成物を使用してフォトリソグラフィ法にて形成する場合を例に、詳細に説明するが、製造方法はこれに限定されるものではない。
その遮光金属材料としては、金属クロム、酸化クロム、窒化クロム等のクロム化合物、ニッケルとタングステンの合金等が用いられ、これらを複数層状に積層させたものであってもよい。これらの遮光金属薄膜は、一般にスパッタリング法によって形成され、ポジ型フォトレジストにより、膜状に所望のパターンを形成する。
本発明の着色樹脂組成物は、ここで青色画素の形成に特に好適に使用される。
ダイコート法において、塗布膜の厚さを調節するためには、リップの走行速度、およびリップからの液状の着色樹脂組成物の吐出量を調整すればよく、スリット・アンド・スピン法においては、主にスリット塗布後のスピン回転数および回転時間によって調整すればよい。
予備乾燥の温度および乾燥時間などの条件は、溶剤成分の種類、使用する乾燥機の性能等に応じて適宜選択されるが、具体的には、乾燥温度は通常40℃以上、好ましくは50℃以上、また、通常80℃以下、好ましくは70℃以下の範囲であり、乾燥時間は通常15秒以上、好ましくは30秒以上、また、通常5分間以下、好ましくは3分間以下の範囲である。
また、再加熱乾燥の温度条件は、予備乾燥温度より高い温度が好ましく、具体的には、通常50℃以上、好ましくは70℃以上、また、通常200℃以下、好ましくは160℃以下、特に好ましくは130℃以下の範囲である。また、乾燥時間は、加熱温度にもよるが、通常10秒以上、好ましくは15秒以上、また、通常10分以下、好ましくは5分以下の範囲とするのが好ましい。乾燥温度は、高いほど透明基板に対する接着性が向上するが、高過ぎるとバインダー樹脂が分解し、熱重合を誘発して現像不良を生ずる場合がある。尚、この塗布膜の乾燥工程としては、温度を高めず減圧チャンバー内で乾燥を行なう減圧乾燥法を用いてもよい。
本発明に係る液晶表示装置は、上述したカラーフィルター(以下、「本発明のカラーフィルター」と称す場合がある。)を備えてなり、例えば、上述した本発明のカラーフィルターと、薄膜トランジスタ(TFT)等の対向基板とを、液晶層を介して対向した構造とすることにより構成することができる。より具体的には、本発明のカラーフィルター上に配向膜を形成し、この配向膜上にスペーサを散布した後、対向基板と周辺シール材を介して貼り合わせて液晶セルを形成し、形成した液晶セルに液晶を注入し、対向電極に結線して作製される。
本発明のカラーフィルターを備えてなる有機ELディスプレイを作成する場合、例えば図3に示すように、透明支持基板10上に、本発明の着色樹脂組成物により青色画素20が形成された青色カラーフィルター上に有機保護層30および無機酸化膜40を介して有機発光体500を積層することによって多色の有機EL素子を作製することができる。有機発光体500の積層方法としては、カラーフィルター上面へ透明陽極50、正孔注入層51、正孔輸送層52、発光層53、電子注入層54、および陰極55を逐次形成していく方法や、別基板上へ形成した有機発光体500を無機酸化膜40上に貼り合わせる方法などが挙げられる。このようにして作製された有機EL素子100は、パッシブ駆動方式の有機ELディスプレイにもアクティブ駆動方式の有機ELディスプレイにも適用可能である。
acid blue 80)(169mg,0.2mmol,1.0e.q.)を加えて、しばらく撹拌した。脱塩水40mlを加え、さらに室温で3時間撹拌した。その後、反応液を濾過し、濾取したものを取り出し、純水を加え超音波洗浄をした後、濾過して、得られた固体を80℃の真空乾燥機で乾燥させ、目的物V-G(300mg,収率80%)を得た。
5.14重量部を水500重量部に溶解し、撹拌しながら1-ナフタレンスルホン酸ナトリウム4.60重量部を加え、室温で1時間撹拌した。氷冷し、沈殿を濾取し、水で洗浄した。得られたケーキを風乾した後、減圧乾燥して、上記構造式で表される目的物X-A(6.11重量部、収率89%)を得た。
WO2008/003604A2に記載の方法にて得られた下記化合物30と、市販の4,4’-ビス(ジエチルアミノ)ベンゾフェノンを原料に用い、目的物I-Fの合成(合成例17)と同様にして目的物I-Iを合成した(収量4.17g,収率61%)。
化合物23とWO2008/003604A2に記載の方法で得られた化合物30を原料に用い、目的物I-Fの合成(合成例17)と同様にして目的物I-Kを合成した(収量791mg,収率88%)。
また奇数電子系の色素2に関しては最低励起状態の励起エネルギー(ΔElowest(色素2))と、式(iii)を満たしているかどうかを表41に示す。
なお、目的物において、色素2はフタロシアニン化合物またはアントラキノン化合物部分であり、色素1はトリアリールメチン化合物部分である。
前記合成例10にて得られた目的物X-A 1mgを、プロピレングリコールモノメチルエーテルアセテート/プロピレングリコールモノメチルエーテル混合溶剤(重量比4/6)に溶解し、得られた溶液の吸光スペクトルを、(株)日立ハイテクノロジーズ製 日立分光光度UV-3500(Xe光源)にて測定した。
溶液の極大吸収波長λmaxは630nmであり、励起エネルギー(ΔEobs)への換算式 ΔEobs(eV)=1239.8/λmax(nm) を用いて計算すると、目的物X-Aの実測の励起エネルギーは1.97eVであった。
一重項酸素を発生させるための励起エネルギーの実測値0.92eVに、このシフト量0.55eVを足した値、すなわち1.5eV(少数第2位を四捨五入)より、計算により求められたT1状態の励起エネルギーが小さいアニオンを有する薄膜(例えばカラーフィルター用画素)では、アニオンのT1状態の励起エネルギーが一重項酸素の励起エネルギーより小さくなることが期待され、励起エネルギー移動による一重項酸素の発生が抑制されることが期待できる。
[合成例23]
プロピレングリコールモノメチルエーテルアセテート145重量部を窒素置換しながら撹拌し、120℃に昇温した。ここにスチレン20重量部、グリシジルメタクリレート57部およびトリシクロデカン骨格を有するモノアクリレート(日立化成(株)製FA-513M)82重量部を滴下し、更に120℃で2時間撹拌し続けた。次に、反応容器内を空気置換し、アクリル酸27重量部にトリスジメチルアミノメチルフェノール0.7重量部およびハイドロキノン0.12重量部を投入し、120℃で6時間反応を続けた。その後、テトラヒドロ無水フタル酸(THPA)52重量部、トリエチルアミン0.7重量部を加え、120℃で3.5時間反応させ、固形分濃度62重量%の樹脂溶液を得た。こうして得られたバインダー樹脂aのGPCにより測定した重量平均分子量(Mw)は約15000であった。バインダー樹脂aの構造は以下に示す通り(以下の4種の繰り返し単位を含む高分子化合物)であった。
[着色樹脂組成物の調製]
<染料系組成物の調製(実施例1~8,10~18および比較例1~4)>
表42に、実施例1~8,10~18、および比較例1~4に含有される染料(色材)を示す。
色材として表44に記載の色材11.36重量部(比較例5については2種類の合計量)、溶剤としてプロピレングリコールモノメチルエーテルアセテート57.5重量部、分散剤として実施例9についてはアビシア社製「ソルスパース55000」、比較例5についてはビックケミー社製「ディスパービック2000」をそれぞれ固形分換算で3.02重量部、径0.5mmのジルコニアビーズ215.7重量部をステンレス容器に充填し、ペイントシェーカーにて6時間分散させてブルー色材分散液を調製した。
5cm角に切断したガラス基板上に、上記各着色樹脂組成物をスピンコート法により乾燥膜厚1.8μmとなるように塗布し、減圧乾燥させた後、ホットプレート上にて80℃で3分間プリベークした。その後、60mJ/cm2の露光量にて全面露光した後、日立製作所製分光光度計「U-3310」にて、分光透過率を測定し、XYZ表色系における色度(C光源)を算出した。これらの結果を表46、表47に示す。
次に、上記基板を2枚の偏光板の間に、隙間を空けずに密着して挟み、色彩輝度計(トプコン社製「BM-5A」)を用いて偏光板が直交の時の光量A(cd/cm2)と平行の時の光量B(cd/cm2)の比(B/A)から、コントラスト比を算出した。この結果を表48に示した。
有機ELディスプレイ、液晶ディスプレイの双方で要求される輝度(Y)については、同一色度(y)座標での比較では、比較例3が最も高く、以下、実施例14、10、9、16、17、15、13、12、8、11、比較例4、実施例18、7、3、比較例5、実施例1、5、6、4、2の順となっている。比較例5が従来使われている顔料系であるから、実施例1、5、6、4、2は、従来品より低く使いづらい。しかし一方、液晶ディスプレイにおいて極めて重要な特性であるコントラストに関しては、実施例1~8,10~18、および比較例1~4で、比較例5の従来顔料系に比べて極めて高い値を示しており、輝度が低いものであっても補って余りあるほどの特性と言える。
図4に示す有機電界蛍光発光素子を以下の方法で作製した。
ガラス基板1の上にインジウム・スズ酸化物(ITO)透明導電膜を150nm堆積したもの(スパッター製膜品;シート抵抗15Ω)を通常のフォトリソグラフィ技術と塩酸エッチングを用いて2mm幅のストライプにパターニングして陽極2を形成した。パターン形成したITO基板を、アセトンによる超音波洗浄、純水による水洗、イソプロピルアルコールによる超音波洗浄の順で洗浄後、窒素ブローで乾燥し、最後に紫外線オゾン洗浄を行った。続いて、正孔輸送層3として、下記構造式に示す9,9-ビス[4-(N,N-ビスナフチルアミノ)フェニル]-9H-フルオレン(LT-N121,LuminescentTechnology社製)をるつぼ温度285~310℃として、蒸着速度0.1nm/秒で40nmの膜厚で積層した。蒸着時の真空度は1.7×10-4Paであった。
LT-N428のるつぼ温度:320~330℃
LT-N628のるつぼ温度:450~455℃
LT-N428の蒸着速度 :0.1nm/秒
LT-N628の蒸着速度 :0.05nm/秒
この素子に6Vの電圧を印加した際の発光の有無と発光色を評価した。この時のEL発光スペクトルの極大波長は436nmであり、CIE色度座標(正面輝度10~1000cd/m2時のCIE色度座標)は(0.16、0.15)であった。
上記有機電界蛍光発光素子と、実施例1~18、比較例1~5の塗布基板を組合せて色度を測定した。結果を表51に示す。
