Abstract

La présente invention concerne un film réfléchissant blanc comprenant un film blanc et, superposé sur au moins la majeure partie de sa surface, une couche de revêtement ayant des particules sphériques contenant un absorbeur d'ultraviolets et/ou un stabilisateur de lumière. Ainsi, elle fournit un film réfléchissant blanc capable d'offrir, dans un panneau lumineux à cristaux liquides, une amélioration de la luminosité et un maintien de la luminosité lors d'un usage à long terme.
