〔12〕前記低反射スプレーコート層が、光透過性を有する上記〔1〕~〔11〕のいずれか一項に記載の低反射材。
〔14〕基材フィルムをさらに備え、前記低反射スプレーコート層が前記基材フィルムの一方の主面側及び他方の主面側にそれぞれ設けられた上記〔1〕~〔12〕のいずれか一項に記載の低反射材。
図1は、本発明の第一実施形態の低反射材100の要部を示す断面図である。この低反射材100は、基材11と、この基材11の一方の主面11a側に設けられた厚み3~100μmの低反射スプレーコート層21と、基材11の他方の面11b側に設けられた粘着層31と、を備えている。すなわち、本実施形態の低反射材100は、低反射スプレーコート層21、基材11、及び粘着層31が、少なくともこの順に配列された積層構造(3層構造)を有する。なお、この積層構造において、低反射スプレーコート層21は表側の最表面に配置されるとともに粘着層31は裏側の最表面に配置されており、低反射スプレーコート層及び粘着層31は、表側及び裏側の最表面にそれぞれ露出した状態で配置されている。なお、低反射スプレーコート層21の表面21aには、本発明の趣旨を逸脱しない範囲において、必要に応じて、帯電防止層や保護層や防汚層や抗菌層や反射防止膜や印刷層等の任意の層が設けられていてもよい。また、低反射スプレーコート層21の表面21aは、本発明の趣旨を逸脱しない範囲において、必要に応じて、帯電防止処理や防汚処理や抗菌処理や反射防止処理等の任意の表面処理が施されていてもよい。
測定長さ:4.0mm
カットオフ波長:0.8mm
測定速度:0.6mm/s
触針:先端半径2μm、頂角60°円錐型の単結晶ダイヤモンド製
なお、上記第一実施形態では、基材11上に低反射スプレーコート層21を設けた積層構造の低反射材100を示したが、本発明は、基材11や粘着層31を省略した態様でも実施可能である。例えば、上述した基材11を剥離させて、低反射スプレーコート層21のみからなる単層構造の低反射材等として実施可能である。また同様に、粘着層31を設けずに、基材11上に低反射スプレーコート層21を設けた2層積層構造の低反射材等として実施可能である。さらに、上記第一実施形態では、基材11上に低反射スプレーコート層21を1層のみ設けた態様を示したが、基材11の一方の主面11a側及び他方の面11b側に低反射スプレーコート層21をそれぞれ設けた態様でも実施可能である。
