Description

(実施例3)
90/10イソオクチルアクリレート/アクリル酸、0.3重量%のヘキサンジオールジアクリレート、及び0.2重量%のIRGACURE 651光反応開始剤(phototinitiator)(Ciba Specialty)で処方された接着剤組成物を、2本のリボン状の側面発光ダイオード(LED)を22.9cm(9インチ)間隔に(両面接着剤で)取り付けた、0.13mm(5mil)のミラーフィルム(3M(商標)Co.のVikuiti(商標)Enhanced Specular Reflector)にコーティングした。接着剤組成物は、ノッチバーナイフコーターを用いてコーティングし、かつシリコーン剥離ライナ(CP Films T10 0.51mm(2.0mil)ポリエステル剥離ライナ)で被覆した。低強度の紫外線ランプを用いて、接着剤組成物を15分間硬化させた。LEDリボンが完全に封入されるように、接着剤組成物を湿潤厚さ1.78mm(70mil)でコーティングした。接着剤は、厚さ1.02mm(40mil)及び屈折率1.474(アッベ屈折計での計測による)であった。LEDに電力供給できるように、結合点においてリボンから接着剤を除去した。次いで、このLEDが埋め込まれた導光体構成体(22.9cm×91.4cm(9インチ×36インチ)の領域)上に、ポリカーボネートフィルムのない3M(商標)Diamond Grade(商標)Reflective Sheetingを含む可撓性の反射性シーティングを積層した。封入された側面発光LEDに電力供給し、光はPSAの全長22.9cm(9インチ)を容易に通過し、光が反射性シーティングを通って退出する様子が視認可能であった。
