Abstract
(EN)
A plastic optical fiber 1 comprises: a plastic optical fiber body 2; and a coloring material 3 that covers the peripheral surface of the plastic optical fiber body. The coloring material 3 is made of a cured product of a curable composition containing: an active energy ray curable multi-functional acrylate; and a colorant. The reaction rate of a vinyl group of the active energy ray curable multi-functional acrylate of the coloring material 3 is 85% or more.
(FR)
Une fibre optique en plastique (1) comprend : un corps de fibre optique en plastique (2) ; et un matériau colorant (3) qui recouvre la surface périphérique du corps de fibre optique en plastique. Le matériau colorant (3) est constitué d'un produit durci d'une composition durcissable contenant : un acrylate multifonctionnel durcissable par rayonnement d'énergie active ; et un colorant. Le taux de réaction d'un groupe vinyle de l'acrylate multifonctionnel durcissable par rayonnement d'énergie active du matériau colorant est supérieur ou égal à 85 %.
(JA)
プラスチック光ファイバー1は、プラスチック光ファイバー本体2と、その周面を被覆するカラーリング材3とを備える。カラーリング材3は、活性エネルギー線硬化型多官能アクリレートと、着色剤とを含む硬化性組成物の硬化物からなる。カラーリング材3における活性エネルギー線硬化型多官能アクリレートにおけるビニル基の反応率が、85%以上である。
