偏光板を含む、ディスプレイ装置にも関する。
本発明に係るグラフト共重合体は、樹脂成分が当該共重合体のみであっても、高強度の樹脂フィルムを形成することができる。また、従来のようにメタクリル系樹脂にコアシェル型グラフト共重合体を配合して分散させる必要がないため、低ヘイズの樹脂フィルムを容易に形成することができる。更に、前記グラフト共重合体は、ゴム成分を含有しているにも関わらず、貯蔵安定性が良好であり、また、溶剤に溶かしてドープを作製した時に、該ドープに濁りが生じにくいという利点もある。結果、該ドープを使用して溶液流延法により製造される樹脂フィルムのヘイズを低くすることができる。
(グラフト共重合体)
本実施形態に係るグラフト共重合体は、架橋(メタ)アクリル系重合体粒子(a)と、非架橋メタクリル系重合体成分(b)を含む。架橋(メタ)アクリル系重合体粒子(a)はゴム成分であるため、強度の改善に寄与し得る。また、非架橋メタクリル系重合体成分(b)によって優れた耐熱性を達成することができる。メタクリル系樹脂にコアシェル型グラフト共重合体を配合してなる従来の系と対比すると、架橋(メタ)アクリル系重合体粒子(a)は、前記コアシェル型グラフト共重合体におけるコアのゴム成分に相当し、非架橋メタクリル系重合体成分(b)は、マトリックスである前記メタクリル系樹脂に相当し得る。
架橋(メタ)アクリル系重合体粒子(a)は、(メタ)アクリル系ゴム粒子である。本実施形態に係るグラフト共重合体は架橋(メタ)アクリル系重合体粒子(a)を含むことによって、例えばフィルム化した時に高い強度を達成することができる。
非架橋メタクリル系重合体成分(b)は、主にメタクリル系単量体が重合して構成され、架橋構造を有しない(即ち、多官能性単量体を使用しない重合によって得られた)重合体である。非架橋メタクリル系重合体成分(b)の少なくとも一部は、架橋(メタ)アクリル系重合体粒子(a)にグラフト結合しており、これによって、架橋(メタ)アクリル系重合体粒子(a)は凝集しにくくなり、本実施形態に係るグラフト共重合体は貯蔵安定性が良好になり、また、フィルム化した時に低ヘイズを達成することができる。
本実施形態に係るグラフト共重合体は、乳化剤と重合開始剤を用いた通常の乳化重合により製造することができる。具体的には、乳化重合により架橋(メタ)アクリル系重合体粒子(a)を形成した後、その重合系に、非架橋メタクリル系重合体成分(b)を構成する単量体成分を添加して引き続き乳化重合を行って非架橋メタクリル系重合体成分(b)を形成する。これにより、非架橋メタクリル系重合体成分(b)の少なくとも一部が、架橋(メタ)アクリル系重合体粒子(a)にグラフト結合したグラフト共重合体を製造することができる。以上の方法によってグラフト共重合体を製造することで、架橋(メタ)アクリル系重合体粒子(a)が非架橋メタクリル系重合体成分(b)中に十分に分散している構成とすることができる。
本実施形態に係るグラフト共重合体は、溶液流延法によるフィルム製造用樹脂組成物を構成することができる。当該樹脂組成物は、樹脂成分として、本実施形態に係るグラフト共重合体のみを含むものであってもよいが、本実施形態に係るグラフト共重合体に加えて、他の樹脂を含有してもよい。そのような樹脂としては特に限定されず、例えば、メタクリル系樹脂、アクリロニトリルスチレン樹脂、スチレン無水マレイン酸樹脂等のスチレン系樹脂、ポリカーボネート樹脂、ポリビニルアセタール樹脂、セルロースアシレート樹脂、ポリフッ化ビニリデンやポリフッ化アルキル(メタ)アクリレート樹脂等のフッ素系樹脂、シリコーン系樹脂、ポリオレフィン系樹脂、ポリエチレンテレフタレート樹脂、ポリブチレンテレフタレート樹脂等が挙げられる。
前記他の樹脂の含有量としては特に限定されないが、例えば、本実施形態に係るグラフト共重合体100重量部に対して、0~50重量部程度であってもよい。さらに、0~30重量部であってもよく、0~10重量部であってもよく、0~5重量部であってもよく、0~1重量部であってもよい。
前記フィルム製造用樹脂組成物は、これを溶剤に溶解または分散させることで、溶液流延法によって樹脂フィルムを製造する際に使用するドープを構成することができる。
前記ドープは、溶液流延法によって樹脂フィルムを製造するのに使用される。具体的には、前記ドープを支持体表面に流延した後、溶剤を蒸発させることにより樹脂フィルムを製造することができる。
本実施形態に係る樹脂フィルムは、前記フィルム製造用樹脂組成物から構成されるものであり、前述したドープの溶液流延法により形成することができる。該樹脂フィルムの厚みは特に限定されないが、500μm以下であることが好ましく、300μm以下がより好ましく、200μm以下がさらに好ましい。また、1μm以上であることが好ましく、5μm以上がより好ましく、10μm以上がさらに好ましく、30μm以上が特に好ましい。
Rth=((nx+ny)/2-nz)×d
各式中、nx、ny、およびnzは、それぞれ、面内において伸張方向(ポリマー鎖の配向方向)をX軸、X軸に垂直な方向をY軸、フィルムの厚さ方向をZ軸とし、それぞれの軸方向の屈折率を表す。また、dはフィルムの厚さを表し、nx-nyは配向複屈折を表す。なお、フィルムのMD方向をX軸とするが、延伸フィルムの場合は延伸方向をX軸とする。
本実施形態に係る樹脂フィルムは靭性が高く柔軟性に富むものであり、未延伸フィルムであってもよいが、延伸フィルムであってもよい。延伸することにより、樹脂フィルムの機械的強度の向上、膜厚精度の向上を図ることができる。
本実施形態に係る樹脂フィルムは、必要に応じて、公知の方法によりフィルム表面の光沢を低減させることができる。そのような方法としては、例えば、無機充填剤または架橋性高分子粒子を添加する方法が挙げられる。また、得られるフィルムにエンボス加工を施すことにより、プリズム形状やパターン、意匠、ナーリングなどの表面凹凸層を形成したり、フィルム表面の光沢を低減させることも可能である。
