Beschreibung
Zusammenfassung:	Disclosed are compositions, which are stabilized against degradation and yellowing during exposure to ultraviolet light by the presence of certain hindered amine 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.
