Description
図2に示す構造で表示装置用ウィンドウパネルを製造した。シルセスキオキサン層(製品名:Silplus、NSCC社製)100μm)およびPET(50μm)の積層体の透明高硬度層(新日鉄化学制製)に、アクリル系透明粘着剤(透明高弾性層、10μm)を接合し、ここに透明基材層としてPC(200μm)を積層した。これを炭酸ガスレーザで150mm×70mmに切断して試験サンプルを作製した。
透明基材層としてアリール樹脂(200μm)を用いた点を除いては、上記実施例1と同じように試験サンプルを作製した。
PMMAを単一層として500μmで作製した。
アリール樹脂を単一層として500μmで作製した。
上記実施例1、実施例2、比較例1および比較例2で製造されたサンプルの中心の部分に130gの鋼球を落下させて破壊する高さを5cmずつ高めて測定した。その結果を下記表1に示す。
