Abstract
Description
本発明で使用される支持ガラス12は、後述する樹脂層14を介してフレキシブル基材16を支持し、フレキシブル基材16の強度を補強するためのものであれば、特に限定されない。支持ガラス12の組成としては特に制限されないが、その組成は、例えばアルカリ金属酸化物を含有するガラス(ソーダライムガラスなど)、無アルカリガラスなどの種々の組成のガラスを使用できる。中でも、熱収縮率が小さいことから無アルカリガラスであることが好ましい。樹脂層を形成する前に、汚れや異物等を除去するために、その表面を予め洗浄することが好ましい(図1の符号12、図2A参照)。
本発明に係る樹脂層14は、上述した支持ガラス12の第1主面上に固定され、フレキシブル基材16と積層されたガラス積層体30においては第1主面および第2主面を有するフレキシブル基材16の第1主面に密着している。ダイコート法などにより、ダイ80から樹脂材料14Aを吐出させ、支持ガラス12上に薄膜状に塗工し、その後、乾燥させ所望の厚みの樹脂層14を得る(図1の符号14、図2B、図2C)。フレキシブル基材16の第1主面と樹脂層14との間の剥離強度は、支持ガラス12の第1主面と樹脂層14との間の剥離強度よりも低いことが必要である。すなわち、フレキシブル基材16と支持ガラス12とを分離する際には、フレキシブル基材16の第1主面と樹脂層14との界面で剥離し、支持ガラス12の第1主面と樹脂層14との界面では剥離し難いことが必要である。
上記硬化シリコーン樹脂からなる樹脂層14の厚さは特に限定されず、フレキシブル基材16の種類などにより適宜最適な厚さが選択される。なかでも、5~50μmであることが好ましく、5~30μmであることがより好ましく、7~20μmであることがさらに好ましい。樹脂層14の厚さがこのような範囲であると、フレキシブル基材16表面と樹脂層14との密着がより良好となる。また、気泡や異物が介在しても、フレキシブル基材16のゆがみ欠陥の発生をより抑制することができる。また、樹脂層14の厚さが厚すぎると、形成するのに時間および材料を要するため経済的ではない。
本発明における硬化性シリコーン樹脂組成物14Aには、必要に応じて本発明の効果を損なわない範囲で、各種添加剤が含有されていてもよい。添加剤として、通常、ケイ素原子に結合した水素原子とビニル基の反応を促進する触媒を加えることが好ましい。この触媒としては白金系触媒を用いることが好ましい。
硬化性シリコーン樹脂組成物14Aは、R1 3SiO0.5単位(R1は脂肪族不飽和結合を有さない1価炭化水素基であって炭素数1~10のもの)およびSiO2単位を含有すると共に、R1 3SiO0.5単位/SiO2単位のモル比が0.5~1.7であるポリオルガノシロキサンをさらに含んでいても良い。このポリオルガノシロキサンは、一般的な付加反応型のシリコーン粘着剤組成物に含まれるものである。
(A)アルケニル基(例えば、ビニル基など)を有するポリオルガノシロキサン
(B)R1 3SiO0.5単位およびSiO2単位を含有すると共に、R1 3SiO0.5単位/SiO2単位のモル比が0.5~1.7であるポリオルガノシロキサン
(C)SiH基を含有するポリオルガノシロキサン
(D)白金触媒
などの成分を含んでいることが好ましい。これらの成分のうち、(A)成分、(C)成分、(D)成分については、上記硬化性シリコーン樹脂組成物14Aに既に含まれている。例えば(A)成分は上記両末端及び/又は側鎖中にビニル基を有する直鎖状ポリオルガノシロキサンに対応するものであり、(C)成分は上記分子内にハイドロシリル基を有するオルガノハイドロジェンポリシロキサンに対応するものである。
硬化性シリコーン樹脂組成物14Aは、シランカップリング剤をさらに含んでいても良い。これによって、支持ガラス12の表面を活性化して、支持ガラス12と樹脂層14との結合力を向上することができ、これらの間12、14での意図しない剥離を抑制することができる。
前記のように、硬化性シリコーン樹脂組成物14Aを支持ガラス12の第1主面上で硬化させて硬化シリコーン樹脂からなる樹脂層14を形成することが好ましい。そのために、硬化性シリコーン樹脂組成物14Aを支持ガラス12の片面に塗布して硬化性シリコーン樹脂組成物14Aの層を形成し、次いで前記硬化性シリコーン樹脂組成物14Aを硬化させて前記硬化シリコーン樹脂層14を形成する。硬化性シリコーン樹脂組成物14Aの層の形成は、硬化性シリコーン樹脂組成物14Aが流動性の組成物の場合はそのまま塗布し、硬化性シリコーン樹脂組成物14Aが流動性の低い組成物や流動性のない組成物の場合は、有機溶剤を配合して塗布する。また、硬化性シリコーン樹脂組成物14Aの乳化液や分散液などを使用することもできる。有機溶剤などの揮発性成分を含む塗膜は、次いでその揮発性成分を蒸発除去して硬化性シリコーン樹脂組成物14Aの層とする。硬化性シリコーン樹脂組成物14Aの硬化は、揮発性成分の蒸発除去と連続して行うことができる(図2B、図2C参照)。
硬化後の樹脂層14のフレキシブル基材16側の面は、フレキシブル基材16の設置前(好ましくは、設置の直前)に、予めUVオゾン処理された面であって良い。これによって、樹脂層14の表面を活性化して、樹脂層14とフレキシブル基材16との結合力を高めることができる。この効果は、樹脂層14が粘着性を有する場合に顕著である。即ち、この効果は、硬化性シリコーン樹脂組成物14Aがポリオルガノシロキサン(B)を含む場合に顕著である。
樹脂層14と支持ガラス12との高い固定力(高い剥離強度)を付与するために、支持ガラス12表面に表面改質処理(プライミング処理)を行ってもよい。例えば、シランカップリング剤のような化学的に固定力を向上させる化学的方法(プライマー処理)や、フレーム(火炎)処理のように表面活性基を増加させる物理的方法、サンドブラスト処理のように表面の粗度を増加させることにより引っかかりを増加させる機械的処理方法などが例示される。
本発明で使用されるフレキシブル基材16としては樹脂フィルム、金属フィルム、ガラス/樹脂複合フィルム等が例示される。なお、フレキシブル基材16の透明性については製造する電子デバイスがLCDである場合、およびOLEDの光取り出し側アレイ、および太陽光発電パネルの太陽光入射側のアレイである場合は、透明であることが必須となる。一方、トップエミッションタイプの有機ELディスプレイのバックプレート、および太陽光発電パネルのバックプレート等を製造するためであれば、透明である必要は無い。したがって、非透明な材料を用いることが可能となる(図1の符号16)。
図面において、本発明に係るガラス積層体30は、上記した支持ガラス12、樹脂層14、フレキシブル基材16から構成される。上述したように、樹脂層14は剥離性表面を有し、フレキシブル基材16や電子デバイス用パネル40(電子デバイス用パネルの構成部材18が形成されたフレキシブル基材16)を容易に剥離することができる。より具体的には、樹脂層14表面とフレキシブル基材16表面との間の剥離強度が、8.5N/25mm以下であることが好ましく、7.8N/25mm以下がより好ましく、4.5N/25mm以下が特に好ましい。上記強度内であれば、剥離時の樹脂層14の破壊や、フレキシブル基材16等の破壊などが起こりにくく、好ましい。
ガラス積層体30の製造は、支持体20の樹脂層14の表面にフレキシブル基材16を積層する方法(積層方法)が好ましい(図2C、図2D参照)。しかし、ガラス積層体30の製造方法は、この積層方法に限られるものではないことは、上述した通りである。積層方法では、フレキシブル基材16の第1主面と樹脂層14の剥離性表面とは、非常に近接した、相対する固体分子間におけるファンデルワールス力に起因する力、すなわち、密着力によって結合させることができると考えられる。したがって、この場合、支持ガラス12とフレキシブル基材16とを樹脂層14を介して積層させた状態に保持することができる。以下、前記支持体20の樹脂層14の表面にフレキシブル基材16を積層する方法によるガラス積層体30の製造方法を説明する。
本発明において、電子デバイス用パネルの構成部材18とは、フレキシブルな基材を使用したLCD、OLED等の表示装置及び、光発電装置において、フレキシブルな基材上に形成された部材やその一部をいう。例えば、LCD、OLED等の表示装置においては、フレキシブルな基材の表面にTFTアレイ(以下、単に「アレイ」という。)やITOの透明電極等を形成する。さらに、必要に応じて保護層その他の層を形成する。また、カラーフィルタ基板については、RGBの色画素用の着色層を形成する。さらに、表基板と裏基板との間に液晶層を挟持させ、駆動用の各種回路パターン等の部材、またはこれらを組み合わせたものが形成される(図2E参照)。
図1において、支持体付き電子デバイス用パネル10は、支持ガラス12、樹脂層14、フレキシブル基材16、電子デバイス用パネルの構成部材18を備えている。
上述した支持体付き電子デバイス用パネル10の製造方法は特に限定されないが、前記したガラス積層体30のフレキシブル基材16表面上に、電子デバイス用パネルの構成部材の少なくとも一部を形成し、その後フレキシブル基材16と硬化シリコーン樹脂層付き支持ガラスとを分離する方法で製造することが好ましい。
上述した支持体付き電子デバイス用パネル10を得た後、さらに、支持体付き電子デバイス用パネル10におけるフレキシブル基材16の第1主面と樹脂層14の剥離性表面とを剥離して電子デバイス用パネル40を得ることができる。上記のように、剥離時のフレキシブル基材16上の構成部材が電子デバイス用パネルに必要な全構成部材の形成の一部である場合には、その後、残りの構成部材をフレキシブル基材16上に形成して電子デバイス用パネルを製造する。フレキシブル基材16の第1主面と樹脂層14の剥離性表面とを剥離する方法は、特に限定されない。
ガラス積層体を10組準備しフレキシブル基材の第2主面を定盤に真空吸着させたうえで、ガラス積層体の一つのコーナー部のフレキシブル基材と樹脂層との界面に、厚さ0.1mmのステンレス製刃物を差し込み、上記フレキシブル基材の第1主面と上記樹脂層の剥離性表面との剥離のきっかけを与えた。
支持ガラス上に樹脂層を形成した支持体から50mm角のサンプルを切り出し、この樹脂表面に同サイズのガラス基板(厚み=0.7mm)を重ねて評価サンプルとした。このサンプルを300℃に加熱したホットプレートに載置し、10℃毎分の昇温スピードで加熱し、サンプル内に発泡・膨れ、フレキシブル基材の剥がれ現象が確認された温度を熱分解開始温度と定義して評価した。

その後、評価サンプルに、構成例4と同様にして、ポリイミドフィルム(三菱ガス化学、ネオプリムL-3430)を積層して、ガラス積層体を得た。
(構成例9)
直鎖状ポリオルガノシロキサン(A)と分岐状ポリオルガノシロキサン(B)との混合重量比(A/B)を10/90とした以外は構成例4と同様の方法にて、ガラス積層体を得た。
構成例1において使用したシリコーン樹脂の代わりに、光照射により粘着力が低下させることが出来る粘着剤(日東電工社製、アクリル硬化型粘着剤)に変更した以外は同じ方法で支持体を作成した。本支持体についても耐熱性評価1を実施したが、300℃のホットプレートにおいてすぐに白煙が発生し、樹脂層の顕著な劣化が認められた。
