Patent

CA 2579061

A light management film (1) includes a first layer (10) with a thermoplastic resin and a particular phosphonium sulfonate salt, and a second layer (20) formed from a curable composition and having a refractive index of at least 1.5. The light management film exhibits reduced static electricity build-up and reduced dust attraction, making it easier to handle during fabrication of display devices such as the flat panel displays of laptop computers.

L'invention concerne un film de gestion de lumière (1) comprenant une première couche (10) contenant une résine thermoplastique et un sel de sulfonate de phosphonium, et une deuxième couche (20) formée à partir d'une composition durcissable et ayant un indice de réfraction d'au moins 1,5. Ce film de gestion de lumière présente une accumulation d'électricité statique réduite et une attraction de poussière réduite, ce qui le rend facile à manipuler lors de la fabrication de dispositifs d'affichage tels que des écrans plats d'ordinateurs portables.
