村上色彩技術研究所のHM-150Nを使用し、JIS-K-7361の条件で透過率(全光線透過率)を測定した。この際、積層体全体は、光源側に樹脂フィルム(3)が向くように設置した。積層体(A)は、光源側に樹脂フィルム(2)が向くように設置した。積層体(B)は、光源側に樹脂フィルム(3)が向くように設置した。
協和界面科学のドロップメーターDM700と解析ソフトウェアのFAMASを用いて測定した。ステージ上に、CCDカメラから100mm、光源から150mmの位置に積層品サンプル(50mm×50mm)を立てて設置し、光源を背後から当てて、CCDカメラで撮影した。このとき、樹脂フィルム(1)がカメラ側に向くようにし、画面に積層品サンプル端部が入らないように設置した(端部がくるとピントあわせが容易なため)。画像を界面測定解析システムソフトウェアFAMASで確認しながら、フォースハンドルを回して、ピントが合うか否かで判定した。
〇:ピント合わせ成功
×:ピント合わせ不可能
測定対象の積層体中の、100μm~1mmサイズの異物の検査を行った。具体的には、暗室にて、蛍光灯(三波長)に積層体を掲げ、透過光により、目視にて、100μm~1mmサイズの異物の有無の検査を行った。明るい透過光により積層体中の異物の有無が明瞭に検知可能な場合を○、透過光が暗いが積層体中の異物の有無を検知できる場合を△、検知できない場合を×とした。
