<実施例>
図2の構成において、透明基材として膜厚125μmのPET(東レ(株)製のU483−125)を用いた。
<評価内容>
エッチングにより透明導電性膜に配線のパターニングを実施し、透明導電性膜側から目視した際のパターンの不可視性について評価した。
JIS K5600に準拠し、透明導電性膜側の塗膜に1mm間隔の切り込みを縦横11本ずつ入れて100個の碁盤目を作成した。各サンプルにセロハンテープ(セロテープ(登録商標))を貼り付け、消しゴムで複数回擦り付けて密着させた後テープを引き剥がし、塗膜が剥離せず残存した格子の目数を確認した。また、剥離が発生した際には、剥離がアンダーコート層と透明導電性膜、またはアンダーコート層と透明基材のどちらの界面で発生したか確認した。
