Abstract: front page image
(EN)Disclosed are compositions, which are stabilized against degradation and yellowing during exposure to ultraviolet light by the presence of certain nitroxyl, hydroxyl amine and hydroxyl amine salt additives, a method of stabilizing the compositions by the addition of said additives, to the use of such compositions as media in electroactive devices such as electrochromic and electrophoteric devices, and the electroactive devices comprised of these media.
(FR)La présente invention concerne des compositions qui sont stabilisées envers la dégradation et le jaunissement lors de l'exposition à la lumière ultraviolette par la présence de certains additifs à base de nitroxyle, d’hydroxylamine et de sel d’hydroxylamine. Elle concerne également un procédé de stabilisation des compositions par l'addition desdits additifs, l'utilisation de telles compositions en tant que milieux dans des dispositifs électroactifs tels que des dispositifs électrochromiques et électrophorétiques, ainsi que les dispositifs électroactifs composés de ces milieux.
