Description
また、近年ではフレキシブルなフィルム材料を基材としたフィルム液晶パネルが注目され、開発が進んでいる。このフィルム液晶パネルに使用される封止材は、剛直なガラス基板に使用される封止材とは異なり、柔軟性と強靭性に富みフィルム基材に追随することも要求される。更に、この追随性は、実使用を鑑み、フィルム液晶パネルが晒され得る温度環境の変化を模した促進試験後においても要求される。
しかしながら、特許文献1の封止材は、柔軟性と強靭性が不足しており、フレキシブルなフィルム基材への追随性が足らず、促進試験にて封止材がフィルムから剥がれてしまうという問題があった。
更に、液晶パネルの生産性向上の観点から、封止材に使用する樹脂組成物は塗工後に基材上で濡れ広がりやはじきが無いことが求められるが、特許文献1の封止材は、基材上ではじきが発生してしまうという問題があった。

(A)と(B)と(C)の合計100質量部に対して(D)が1~50質量部である、フィルム液晶パネル用の封止材に使用する硬化性樹脂組成物。
〔2〕前記の〔1〕に記載の硬化性樹脂組成物で端部を封止したフィルム液晶パネル。
多官能チオール化合物(A)は、2~6個のチオール基を有する化合物である。多官能チオール化合物(A)は、1種のみを単独で使用することもできるし、2種以上を併用することもできる。このような化合物を含有することで、他成分との間でチオール-エン反応が進行し、硬化性を高めることができる。形成されるチオエーテル結合は、C、O、Nといった原子の結合と比べ、結合角を柔軟に変化できるため硬化物は柔軟性が高く、封止材の基材への追随性を高めることができる。また、チオエーテル結合から成る硬化物は、結合角の高柔軟性を有し、原子同士が結合の隙間を埋めるように高密度に硬化できるため、水分バリア性が高く、湿熱試験後においても水分の影響を受けず液晶の配向乱れを防ぐことができる。
上記式1で表される化合物の中でも、ペンタエリスリトール骨格を有する多官能チオール、ジペンタエリスリトール骨格を有する多官能チオール、イソシアヌレート骨格を有する多官能チオールが好ましい。
その中でも、封止材の水分バリア性を高め、過酷な湿熱試験に曝されても液晶の配向乱れを抑えることができ、且つ、硬化性樹脂組成物の硬化物の柔軟性を高め、封止材の基材追随性を高めることができるため、ジペンタエリスリトールヘキサキス(3-メルカプトプロピオネート)、ペンタエリスリトールテトラキス(3-メルカプトプロピオネート)、トリス-[(3-メルカプトプロピオニルオキシ)-エチル]-イソシアヌレートが好ましい。
多官能ウレタン(メタ)アクリレート化合物(B)は、ジイソシアネート化合物とポリオール化合物、及びヒドロキシル基を有する(メタ)アクリレート化合物を公知の方法で反応させて得られる。多官能ウレタン(メタ)アクリレート化合物(B)は、1種のみを単独で使用することもできるし、2種以上を併用することもできる。このような化合物は、液晶との疎液性が高いため、このような化合物を含有することで、未硬化の硬化性樹脂組成物の液晶への溶解性を低下させ、液晶と長く触れ合った場合でも液晶の汚染を防ぐことが出来る。また、硬化性樹脂組成物の硬化物を強靭化し、封止材の基材への追随性を高めることができる。加えて、含有するウレタン基は、-30℃以下の低温帯から100℃程度の高温帯においてウレタン基同士および他の極性基と水素結合のような強い相互作用を発現できるため、温度環境によらず硬化性樹脂組成物の硬化物が強靭化され、封止材の基材への追随性を高めることが出来る。多官能ウレタン(メタ)アクリレート化合物(B)は、2~3個の(メタ)アクリル基を有する化合物であり、(メタ)アクリル基の数がこの範囲であることで、硬化性樹脂組成物の硬化物が剛直にならず、封止材の基材への追随性を高めることができ、また、極性が高まりすぎず、他成分との相溶性を保つことができる。
多官能アリル化合物(C)は、2~4個の(メタ)アリル基を有する化合物である。多官能アリル化合物(C)は、1種のみを単独で使用することもできるし、2種以上を併用することもできる。(C)を含有することで、硬化性樹脂組成物の硬化物の強靭性が増し、封止材の基材への追随性を高めることが出来る。また、他成分との架橋ネットワークの形成に優れるため、封止材は水分バリア性に優れ、さらには、(メタ)アクリル化合物と比べ耐湿試験中に加水分解が起こりにくいため、耐湿試験中において封止材の高い水分バリア性を維持することができ、過酷な湿熱試験に曝されても液晶の配向乱れを抑えることができる。
多官能アリル化合物(C)は、下記式2で表される化合物が好ましい。
式中のR2は、水素原子又はメチル基であり、硬化性樹脂組成物の硬化物の柔軟性を増し、封止材の基材への追随性を高めるという観点から水素原子が好ましい。bは2~4の整数であり、この範囲であることで、封止材の水分バリア性を高め、過酷な湿熱試験に曝されても配向乱れを抑えることができ、且つ硬化性樹脂組成物の硬化物の柔軟性が増し、封止材の基材への追随性を高めることができる。また、R3も同様の観点から、2~4価である。R3の炭素数は2~40であり、好ましくは2~30であり、より好ましくは2~25である。R23の炭素数がこの範囲内であれば、硬化性樹脂組成物の硬化物の架橋密度が十分であり、封止材は良好な水分バリア性が得られるため、過酷な湿熱試験に曝されても配向乱れを抑えることができる。
bが3である化合物としては、具体的には、トリアリルイソシアヌレート、ペンタエリスリトールトリ(メタ)アリルエーテル、グリセリントリ(メタ)アリルエーテル、トリメチロールプロパントリアリルエーテル等が挙げられる。
bが4である化合物としては、具体的には、1,3,4,6テトラ(メタ)アリルグリコールウリル、1,3,4,6テトラ(メタ)アリル-3a-メチルグリコールウリル、ペンタエリスリトールテトラ(メタ)アリルエーテル、テトラ(メタ)アリルオキシエタン等が挙げられる。
上記(メタ)アリル化合物の中でも、封止材の経時での着色を防ぐことができ、また、封止材の水分バリア性を高め、過酷な湿熱試験に曝されても配向乱れを抑えることができ、更には、硬化性樹脂組成物の硬化物の強靭性を高め、封止材の基材への追随性を高めることができるという観点からイソシアヌレート骨格を有する(メタ)アリル化合物、ペンタエリスリトール骨格を有する(メタ)アリル化合物等が好ましい。中でも、具体的には、1,3-ジアリル-5-グリシジルイソシアヌレート、トリアリルイソシアヌレート、ペンタエリスリトールトリアリルエーテル、ペンタエリスリトールテトラアリルエーテルが好ましい。
球状フィラー(D)は、無機物または有機物から成る平均粒子径が15μm以下の球状のフィラーである。球状フィラー(D)は、1種のみを単独で使用することもできるし、2種以上を併用することもできる。(D)を含有することで、未硬化の硬化性樹脂組成物の形状安定性を向上させ、基材上で長時間塗れ広がりやハジキなく形状を保つことができる。
有機物から成る球状フィラー(D)としては、例えば、アクリル粒子、ウレタン粒子、スチレン粒子、メラミン粒子、アクリル―スチレン粒子等が挙げられる。この中でも、硬化性樹脂組成物の柔軟性および基材への接着性を損ねず、封止材の基材への追随性を維持することができるという観点から、アクリル粒子、ウレタン粒子が好ましい。
光重合開始剤(E)は、上記(A)、上記(B)、上記(C)、及びその他に重合性化合物が添加される場合はその重合性化合物の光による硬化反応を促進するために添加され、硬化性樹脂組成物の硬化に必要な光照射を少なくすることができる。光重合開始剤(D)は、1種のみを単独で使用することもできるし、2種以上を併用することもできる。光重合開始剤としては、光ラジカル重合開始剤、光カチオン重合開始剤、光アニオン重合開始剤等があげられる。この中でも、反応時間を短縮し、生産性を向上させる観点から光ラジカル重合開始剤が好ましい。
本発明の硬化性樹脂組成物には、本発明の目的を阻害しない範囲において、多官能(メタ)アクリル化合物(F)を含有していてもよい。多官能(メタ)アクリル化合物(F)は、多官能ウレタン(メタ)アクリレート化合物(B)とその他成分との相溶化剤として働き、硬化性樹脂組成物の未硬化物が液晶と長く触れ合った場合でも液晶の汚染を防ぐ性能を向上させることが出来る。多官能(メタ)アクリル化合物は、硬化性樹脂組成物の硬化性を阻害しないという観点から(メタ)アクリル基を2個以上有するものが良い。また、硬化性樹脂組成物の硬化物の柔軟性を低下させ、基材への追随性を阻害させないという観点から、(メタ)アクリル基を6個以下有するものが良い。このような多官能(メタ)アクリル化合物としては、既知の化合物を用いることができる。中でも、相溶化剤としてより良く働くとともに、硬化性樹脂組成物の硬化物の柔軟性を低下させず、基材への追随性を阻害させない観点から下記の式3で表される化合物が好ましい。
本発明の硬化性樹脂組成物には、本発明の目的を阻害しない範囲において、界面活性剤(G)を含有していてもよい。界面活性剤(G)は、疎水性が高いため、硬化性樹脂組成物中に含有することで封止材の水分バリア性が向上し、過酷な湿熱試験に曝されても液晶の配向乱れを一層抑制することができる。界面活性剤(G)としては、公知のシリコン系界面活性剤、フッ素系界面活性剤、アクリル系界面活性剤等を特に制限無く用いることができるが、水分バリア性を高めるという観点からフッ素系界面活性剤が好ましい。フッ素系界面活性剤の市販品としては、具体的には、DIC(株)製の「メガファックF-410」、同「F-430」、同「F-444」、同「F-472SF」、同「F-477」、同「F-552」、同「F-553」、同「F-554」、同「F-555」、同「F-556」、同「F-558」、同「F-559」、同「F-561」、同「R-94」、同「RS-72-K」、同「RS-75」等が挙げられる。これら界面活性剤は、単独でも2種以上を併用しても良い。
本発明の硬化性樹脂組成物には、本発明の目的を阻害しない範囲において、シランカップリング剤(H)を含有していてもよい。シランカップリング剤(H)は、他成分や基材との相互作用を向上させ、硬化性樹脂組成物中に含有することで、硬化性樹脂組成物の硬化物の強靭性や基材への接着性が向上し、温度環境の変化によらず基材への追随性をより高めることができる。公知のシランカップリング剤を特に制限無く用いることができるが、封止材を長期間使用した際、シランカップリング剤のブリードアウトによって液晶を汚染し、液晶の配向乱れを発生させてしまうことを防ぐという観点から、(メタ)アクリル基やビニル基、チオール基、エポキシ基、イソシアネート基等の反応性官能基を持つものが好ましい。具体的には、3-(メタ)アクリロキシプロピルメチルジメトキシシラン、3-(メタ)アクリロキシプロピルメチルトリメトキシシラン、3-(メタ)アクリロキシプロピルメチルジエトキシシラン、3-(メタ)アクリロキシプロピルメチルトリエトキシシラン、ビニルトリメトキシシラン、ビニルトリエトキシシラン、3-メルカプトプロピルメチルジメトキシシラン、3-メルカプトプロピルメチルトリメトキシシラン、3-グリシドキシプロピルメチルジメトキシシラン、3-グリシドキシプロピルトリメトキシシラン、3-グリシドキシプロピルメチルジエトキシシラン、3-グリシドキシプロピルトリエトキシシラン、3-イソシアネートプロピルトリエトキシシラン等が挙げられる。これらシランカップリング剤は、単独でも2種以上を併用しても良い。
本発明の硬化性樹脂組成物は、本発明の目的を阻害しない範囲において、上記多官能(メタ)アクリル化合物(F)、界面活性剤(G)、シランカップリング剤(H)以外にも、エポキシ化合物や、硬化促進剤、紫外線吸収剤、光安定化剤、酸化防止剤、重合禁止剤、レベリング剤、密着付与剤、可塑剤、消泡剤、遮光材、導電材、スペーサー等の添加剤を含有していてもよい。
本発明の硬化性樹脂組成物は、液晶と混ざりにくい性質を持つ前記(B)を含有することで未硬化の状態での液晶汚染性を低下することができる。また、本発明の硬化性樹脂組成物は、多官能チオール化合物(A)のチオール基と、多官能ウレタン(メタ)アクリレート化合物(B)及び多官能(メタ)アリル化合物(C)の重合性不飽和結合との間にチオール-エン反応が進行し硬化物が得られる。形成されるチオエーテル結合は結合角を柔軟に変化でき、硬化性樹脂組成物の硬化物の柔軟性を高め、封止材の基材への追随性を高めることができる。加えて、多官能ウレタン(メタ)アクリレート化合物(B)の含有するウレタン基は、低温から高温帯においてもウレタン基同士及び他の極性基と水素結合のような強い相互作用を発現できるため、温度環境によらず硬化物が強靭化され、封止材の基材への追随性を高めることができる。また、チオエーテル結合から成る硬化物は、結合角の高柔軟性から原子同士が結合の隙間を埋めるように高密度に硬化できるため、水分バリア性が高く、過酷な湿熱試験に曝されても水分の影響を受けず液晶の配向乱れを抑制することができる。更には、球状フィラー(D)を含有することで、未硬化の硬化性樹脂組成物の形状安定性を向上させ、基材上で長時間濡れ広がりやはじきなく形状を保つことができる。これより、本発明の硬化性樹脂組成物が、未硬化の状態で液晶と接触しても液晶非汚染性を低下させ、且つ、基材上で長時間濡れ広がりやはじきなく形状を保つことができ、また、硬化性樹脂組成物の硬化物からなる封止材が、過酷な湿熱環境下で液晶と接触した状態でも液晶の配向乱れを抑制することに加え、温度環境によらず基材への追随性を高めるためには(A)と(B)、(C)、(D)のいずれも欠く事はできない。また、(A)、(B)、(C)、(D)含有の硬化性樹脂組成物に更に前記(E)を用いることで光照射のみで硬化し上記効果を発現することができる。なお、一般的には(D)を含有することで、硬化性樹脂組成物中の光透過率が低下し光照射のみでの深部の硬化は困難になるが、本発明の硬化性樹脂組成物は、多官能チオール化合物(A)が連鎖移動剤としても寄与するため、光照射のみで十分に深部まで硬化することができる。加えて、(B)と(C)の配合質量比率(B)/(C)が0.1~1.0、且つ(A)のチオール基の官能基濃度と(B)及び(C)の重合性不飽和結合の官能基濃度の合計の割合(チオール基/重合性不飽和結合)が0.5~3.0、さらには、(A)と(B)と(C)の合計100質量部に対して(D)が1~50質量部の割合となるように配合されることで、硬化性樹脂組成物が、未硬化の状態で液晶と接触しても液晶を汚染せず、且つ、基材上で長時間濡れ広がりやはじきなく形状を保つことができ、更には、硬化物が過酷な湿熱環境下で液晶と接触した状態においても液晶の配向乱れを発生させないことに加え、温度環境の変化によらず基材への追随性に優れるものとなる。チオール基の官能基濃度とは、(A)と(B)と(C)の合計100質量部中(A)の質量部数×(A)のチオール基の官能基数/(A)の分子量、で表される数であり、(B)及び(C)の重合性不飽和結合の官能基濃度の合計とは、[(A)と(B)と(C)の合計100質量部中(B)の質量部数×(B)の(メタ)アクリル基数/(B)の分子量]+[(A)と(B)と(C)合計100質量部中の(C)の質量部数×(C)のアリル基数/(C)の分子量]で表される数である。
また、本発明の硬化性樹脂組成物において、封止材の水分バリア性を高め、過酷な湿熱試験下での配向乱れをより抑制するためには、(B)と(C)の配合質量比率(B)/(C)が0.1~0.6であること、硬化性樹脂組成物の硬化物の柔軟性と強靭性を高め、封止材の基材への追随性をより高くするためには、(B)と(C)の配合質量比率(B)/(C)が0.2~1.0であること、低温下から高温下において硬化性樹脂組成物の硬化物の柔軟性と強靭性を高め、温度環境の変化によらず封止材の基材への追随性をより高くするためには、(B)と(C)の配合質量比率(B)/(C)が0.3~1.0であることが好ましく、すなわち、封止材が過酷な湿熱試験に曝されても液晶の配向乱れを抑制する、封止材が温度環境によらず基材への高い追随性を有する、といった各性能をより高く並立するためには、(B)と(C)の配合質量比率(B)/(C)が0.3~0.6であることが好ましい。
さらには、本発明の硬化性樹脂組成物において、封止材の水分バリア性を高め、過酷な湿熱試験下での配向乱れをより抑制するためには、(A)のチオール基の官能基濃度と(B)及び(C)の重合性不飽和結合の官能基濃度の合計の割合(チオール基/重合性不飽和結合)が0.7~2.3であることが好ましく、硬化性樹脂組成物の硬化物の柔軟性と強靭性を高め、封止材の基材への追随性をより高くするためには、(A)のチオール基の官能基濃度と(B)及び(C)の重合性不飽和結合の官能基濃度の合計の割合(チオール基/重合性不飽和結合)が0.7~2.5であることが好ましく、低温下から高温下において硬化性樹脂組成物の硬化物の柔軟性と強靭性を高め、温度環境の変化によらず封止材の基材への追随性をより高くするためには、(A)のチオール基の官能基濃度と(B)及び(C)の重合性不飽和結合の官能基濃度の合計の割合(チオール基/重合性不飽和結合)が0.8~2.4であることが好ましく、すなわち、封止材が過酷な湿熱試験に曝されても液晶の配向乱れを抑制する、封止材が温度環境によらず基材への高い追随性を有する、といった各性能をより高く並立するためには、(A)のチオール基の官能基濃度と(B)及び(C)の重合性不飽和結合の官能基濃度の合計の割合(チオール基/重合性不飽和結合)が0.8~2.3であることが好ましい。
加えて、本発明の硬化性樹脂組成物において、未硬化の硬化性樹脂組成物の形状安定性を向上させ、より基材上で塗れ広がりやハジキなく形状を保つことができためには、(A)と(B)と(C)の合計100質量部に対して(D)が2~50質量部であることが好ましく、硬化性樹脂組成物の硬化物の柔軟性と強靭性を損なわず、温度環境の変化によらず封止材の基材への追随性をより高くするためには、(A)と(B)と(C)の合計100質量部に対して(D)が1~40質量部であることが好ましく、すなわち、硬化性樹脂組成物が未硬化の状態で基材上にて長時間濡れ広がりやはじきなく形状を保つことができ、封止材が温度環境によらず基材への高い追随性を有するためには、(A)と(B)と(C)の合計100質量部に対して(D)が2~40質量部であることが好ましい。
そして、本発明の硬化性樹脂組成物において、(A)と(B)と(C)の合計100質量部に対する(E)の割合は、好ましくは0.01~10.0質量部であり、より好ましくは0.1~10.0質量部である。(E)の含有量を上記範囲とすることにより、過酷な湿熱環境下で液晶と接触した状態においても液晶の配向乱れを発生させないことに加え、温度環境の変化によらず基材への追随性に優れる封止材を得ることができる。

本発明のフィルム液晶パネルとは、上記プラスチック透明フィルム基材を用いた基板にて形成された液晶パネルであり、フィルム液晶パネル用の封止材は、上記フィルム液晶パネルに用いられる封止材である。
本発明のフィルム液晶パネルは、一対の上記基板の一方に本発明の硬化性樹脂組成物を塗布した後、その内側に液晶を滴下しもう一方の基板を重ね合わせ、光を照射し上記硬化性樹脂組成物を硬化させることで形成される。また、一対の上記基板の一方に液晶と硬化性樹脂組成物を含む高分子分散型液晶を塗布し、もう一方の基板を重ね合わせ、光を照射し高分子分散型液晶を硬化させた後、本発明の硬化性樹脂組成物を外周に塗布し、光を照射し硬化性樹脂組成物を硬化させることで形成させるものもある。

フィルム液晶パネルの汚染性は、上記のようにフィルム液晶パネルを形成し、実際に電圧を印加して配向具合を確認する手法に加えて、電圧保持率の測定によって評価することも出来る。電圧保持率は液晶セルに電圧を印加し充電された電荷が一定時間後にどの程度保持されているかを確認する評価方法であり、液晶が汚染されている場合、電荷が保持されずに電圧保持率は低下する。汚染性がなく良好な電圧保持率は90%以上が好ましく、より好ましくは95%以上である。
